[Q] SD Card Worth It?

I am going to pick one of these up, but before I did, had a quick question (anyone with a WP7 can answer)
Do you feel that 8gb is enough space? Or do you wish you had more? Should I get an SD Card?

Most definitely. I have loaded most of my music and a few videos and I already used over 6GB. That's pretty much all the stock phone has. Now, I have over 14GB still left. Might put some movies on it.

My only disappointment in the focus is the 8GB stock NAND. For a $199 on contract device, 16GB really should be the minimum, especially considering a few other WP7 phones, to say nothing of Android phones and the iPhone, all start at $199 with 16GB.
That said, adding the SD card isn't that big a deal as long as you do it before you've filled the device up. For some reason there seems to be no ability to do a full backup of the phone by any means I've been able to find.

The problem with the SD Cards is that there's intense confusion/miscommunication about which cards work well. Just because it works with 6GB doesn't mean anything. What seems to happen is once you get to 8GB filled, the phone's performance takes a nose-dive, sometimes leading to losing all data.

"Enough space" depends on you, not us. I have an iPhone, iPad and iPod, all 16GB units, each with some 14GB or so of music & apps on them so it the first thing I did when I brought the Focus home was slap an 8GB card in there, format it and load it up. I have maybe 2GB free and it's worked without a single glitch for the past two weeks. For reference, mine is a Sandisk class 2. People seem to have problems with cards other than Sandisk and other than class 2 and I noticed absolutely no performance problems so if you're going to try it, try that and keep the receipt in case you need to return or swap it should something go sour.

Enough Space?
I agree with Mark, whether there is enough space or not really depends on what your usage requirements are.
I had a 32GB Zune and when I bought my Samsung Focus the Zune had over 20GB of data on it. So for me adding and 32GB SD card to the Focus was not only a desire but a very strong selling point for the Phone.
And yes, I am seeing a few issues with the Sandisk Card that is in it. Currently they are not enough to make me yank the Card because I (again) bought the device to specifically be a convergence device for myself and I am at heart a tester and tinkerer so figuring how exactly how WP7 works.doesn't work with an SD Card and the statement that MS and Samsung are working on a fix is enough for me right now.
Smaller Sized Cards seem to be more reliable than larger cards (not to mention less expensive) but that appears to anecdotal evidence as well. My 32GB Sandisk only causes freezes and resets when on Battery for example and I've not had anyone else confirm if they are seeing the same.
Not great answers but, hey, this is the fun of learning as we go along...

I have more than 11GB on my Focus with no issues at all. No slow-downs, no hiccups, no data loss period. I am currently using a PNY 16GB Class 2 card. I previously had a Centon 8GB Class 6 card with the same results.
If you read the thread on MicroSD cards, it seems there are some cards that have been working pretty much flawlessly. Both of the cards I mentioned have worked perfectly for me. I gave the 8GB to a friend and he is using it in his Focus as well.

For me, to really make a portable phone/audio/video device be best for me it would need at least 150GB of storage... and a few TB if i wanted to listen to music lossless and a few movies.

You know, I was thinking about this the other day...the phone has 8GB of internal memory and if you put in an SD card it stripes data across it and the internal memory. If the card is 8GB or smaller that's fine but what happens if the SD card is larger than internal memory? It doesn't stripe the first 8GB and set the rest up as another partition and it does appear to use but it can't be striped. Now you've mentioned that smaller sized cards work better and my 8GB card works perfectly. I wonder if the file system's attempt to work with a larger card is inherently unstable? I know that if you put two different sized drives in a Windows box and stripe across them you will only end up with double the size of the smallest drive, not the actual sum of the two. Might be an interesting poll...indicate the size of your SD card and if the phone has been 100% stable since inserting it.

I'm not totally convinced based on comments in blogs that the disks are "striped". I think a lot of people are saying this and maybe using the term out of context and everyone just keeps using it. Has Microsoft actually come out to say "WP7 performs RAID 0 configuration"? For a phone OS which was never intended to see anything other than a single drive, don't you think throwing a RAID controller in there just for kicks is a little absurd?
The other term is "span" and if I had money, I'd bet that the two disks were spanned as a single partition, as opposed to striping like RAID 0 does.
Despite all of that, I have tried a 16gb class 4 with more issues than I cared for and currently have an 8gb class 4 with negligible issues. Any card you get, I'd run on Vista/Windows 7 and test for ReadyBoost. That at least tests the card for random access speed, which is important. My 16gb failed readyboost and had lots of issues in my Focus, whereas the 8gb passed and the only issues I've seen with that one are issues that other people might have experienced on their own phones sans sd card.

I've read both, striped and spanned...who knows. Considering how slow SD memory always was in old WinMo devices, I didn't think it absurd to stripe data to provide the same kind of speed boost you get when striping hard drives. Hard as it might be to believe, it may have just been that WinMo was slow. I hadn't thought of the readyboost test, that's a good idea. Readyboost is pretty picky.

32 GB vs 16 GB

what are you guys getting? I ve pre-ordered for the 16gb but thinking to maybe switch to 32gb, for I ve heard 32gb is noticeably faster cuz of bigger storage Idk if that is true... This is my first time using android tablet, ditching ipad finally. I know there is an extended sd card option but still would you buy 32 gb for $50 more?

32gb... Some of these games coming out are over 1gb each, and some are approaching 2gb. I like to have things installed and not have to do the install/uninstall shuffle. Plus to have space for other things. All Media and storage go on the 64gb micro sd card though.

I pre-ordered a 16GB black from Best Buy, then changed my mind to a 32 GB white.
Best to have too much than too little.

They kind of want you to buy the 32gb version since the 16gb version is only 50 bucks less. That being said, I think it matters less on a tablet than on a phone because I always root my tablets. There's less downside from voiding warranty because my tablet is always safe and secure in it's case inside my bag while I'm on the run whereas my phone can be accidentally dropped at any time. That's just me though.
The faster speed from having a larger internal sd card is of somewhat miniscule benefit. For something like a 128gb and 256gb ssd, the improvement will be mildly noticeable but not so much on a tiny sd card. Get the one that fits your needs.
I really want a black one because I prefer understatement (don't want to get robbed too). So if I get a 32gb version, it will be because the 16gb version is only available in white in the states right now.

I got the black 32GB from Best Buy always nice to have extra, also have a 64GB sd card for it.

changed to 32 gb...lol

I was on the fence about getting which one to get too. I decided to get the 16gb because of the Amazon $50 gift card promotion. I don't game alot, so the huge app sizes are not as much as an issue for me. I will put in a 64gb sd card for videos and pictures.

i never game as much as i think i'm going to and always have tons of space left over, lol. i bought just about every emulator and a bunch of games, most of which i've never played or never installed.
i did preorder the 32GB for two reasons - 1: if i want black and by the 11th there's only one choice
2: i swear i'm gonna start playing those games i bought, lol
i also bought another 64GB sd for media. i got a 64 in my ativ 500t and 700t but only a 32 in my gn8. the only reason my phones have 32gb is b/c tw roms are crazy huge compared to AOSP and nandroids are taking 4GB a piece! otherwise 16GB would have been enough.

I feel you about the size of the tw roms. Hopefully, there will be root and a streamlined tw rom to help out a bit with that.

For SSDs why is there any benefit to speed based on size at all? I assumed the OP was just confusing RAM with storage.
For magnetic HDDs, bigger is faster for the same amount of data because on a bigger drive more of that data can be stored towards the edge. The edge of the platter moves quicker, so you get faster R/W times.
Why would different size SSDs have different speeds?

You get faster speeds on larger SSD drives because of the way the controller works. There are more cells working in parallel which increases speed. Each individual bit of information acts rather slowly in emmc and is pretty consistent across devices as long as the type of Nand is the same. It's the controller which makes the difference in speed and the controller is better when it has more parallel units working in tandem. So in the SSD world, bigger is better.

32g enough for video games

For those hoping for a MicroSD card with the rumoured active S6, We're doomed.

While the headline might seem familiar with the same keywords of Samsung producing 128GB flash storage modules, this story is different from the previous one. Last month, Samsung announced a 128GB storage based on the new and anticipated UFS 2.0 standard and targeted for flagship high-end devices — it made its debut in the Galaxy S6 and S6 Edge. This new module, however, is based on the established eMMC standard and it will appear in mass market mid-range devices.
If you missed the previous explanation about the difference between eMMC and UFS, you should know that eMMC is the de-facto standard for storage on smartphones right now. It differs from the swanky UFS 2.0 in two areas: it can't read and write simultaneously and it doesn't have a Command Queue system to sort and re-order the tasks it needs to perform. By comparison, it is slower than UFS, but it remains significantly faster than external MicroSD storage.
Samsung's new 128GB flash uses eMMC 5.0 (there's a newer 5.1 standard that is slightly faster), and can deliver sequential reading speeds of 260 MB/s, random reading at 6000 IOPS (input/output per second), and random writing at 5000 IOPS. It is a "value-focused" module and the company's aim is for "mid-market smartphones [to] be able to increase their storage capacity to 128GB." There's no word on when this module will start appearing in phones and tablets, but you should hear about 128GB devices from Samsung and other OEMs later in the year.
It's worth noting that Samsung also highlights the speed gains compared to external memory cards in its press release, so you might want to take the hint that the company's devices that will be equipped with this new flash module won't have a MicroSD slot. Financially, it makes a lot of sense given the mark-up difference that added built-in storage incurs compared to external storage. And Samsung can rake in that extra casheesh instead of sending it SanDisk's (or Kingston's or other companies') way.

Complaining about the lack of micro SD is still a thing? I thought we went over this... multiple times...
It's time to accept the reality that all of the S6 versions will not have micro SD. If you need a micro SD then simply grab another phone.

I don't buy it. Does that mean USB OTG isn't going to work, either?

There's nothing in the software which prohibits it from being discovered by a file browser. It works but read/write speed in the music/video player apps is slower than if the files were on the internal storage themselves.

So, is this a confirmation on a feature which may or may not exist, on a phone which doesn't currently exist?

The SD card was an issue when the phone only had 8 or 16 GB of internal storage. Now that the phone has minimum 32 GB with an option of having 64Gb (of much faster storage) for a manageable price I don't think the SD card is a problem anymore. Most people i know only use a 32 GB SD card anyway.

Looks like USB OTG will work fine:

Samsung's Galaxy S6 Active may come with a microSD card slot, but at a high cost
Reddit user “garshol” sat down with a Samsung rep a couple of days ago to discuss the new Galaxies, and the Active was among the topics at the table. The ruggedized version of Sammy's latest flagship will boast “similar” hardware under the hood, according to the report, and will come with an SD card slot. However, it will also come at a cost – according to garshol's posts, the Active's camera will be a lower class than the one on the flagship model, but at least it may still have OIS. Additionally, the endurance model will not have a fingerprint scanner, and will lack a heartbeat sensor.
http://www.phonearena.com/news/Sams...-microSD-card-slot-but-at-a-high-cost_id67615

These tradeoffs would be acceptable to me. I'm curious about what the dimensions and weight of the phone will be.
I've read a few comments on some sites that suggest including an SD card slot and its associated controller slow down the overall performance of a phone, even if there's no SD card inserted. I have no idea if this is true, but if so, I can at least understand why the S6 lacks SD from a performance standpoint. I've assumed that Samsung's assertion that SD was too slow for the S6 was because they didn't want benchmarks/comments that the built-in internal storage is lightning fast, but SD card is still slow. More of a "we don't want any suggestions that ANY aspect of the S6 is slow", even though most users are well aware of SD's limitations and are primarily interested in simply having the ability to easily expand the storage space despite it not keeping up with the phone storage speeds.

I definitely will not be getting the S6 due to the lack of removable battery and lack of micro SD slot. I think that HTC and LG are going in the right direction here.

Xperia z3c max sdxc size

I was having a conversation with a friend who claims that most phones made in the last 2 years can take a sdxc card up to 2tb and the 128gb limit mentioned is null. I saw some new phones listed as 200gb max instead of the 128, but would they take up to 2tb I wonder. What do you guys think about this

i think it can be capable of having 128gbs without problems, no more, but lets wait until someone confirms it having a sony running more than 128gigs

If you use SD Cards above 64Gb, Zen/vr/tripndroid are the best choices since they work well with High-Speed Cards. Also At 64 GB if you are using a UHS-3 Card you can set the Read Ahead Cache to around 4096Kb but if not 2048Kb is fine as well... I don't really recommend 200GB Cards since they strain the system, theres probably a reason why the Z3C is only advertised to handle 128GB Cards

What? The Linux kernel has no problem handling exabyte block devices. SDXC can handle up to 2 TiB. What part of the system is being strained, and how so? I don't see any reason that any device supporting SDXC would struggle with anything up to 2 TiB.

My old Xperia Play officialy supports only 32GB, however 128GB SD card worked well in it. So I don't think, there is some real limit, but I didn't see larger SD card than 512 GB.

No worries, I just wasn't sure if you knew something I didn't. I wouldn't put too much faith in their marketing team. They probably just found the biggest card they thought existed and made sure it worked. Either that or they were afraid "2" would look smaller than a competitor's listing that says "128" to people who have no idea what "GB" or "TB" mean.
I would love to have a 2 TB sd card. That wouldn't come close to holding my entire movie collection, but at least I would be able to fit my entire music collection plus a bunch of movies. I can't even fit half my music on a 200 GB card. Having all my music on my phone would be amazing. I expect 2 TB cards will be around in about five years. It will become affordable just like 200 GB has.

good advices
thanks

I was thinking the same. Even though it's obvious, it isn't obvious to everyone (actually, there is only a small minority of the android-users who even know that android uses a linux kernel, even fewer knows what it is).
The system COULD be put under strain though, if you format the micro SD-card in to NTFS. I have an i7 4710MQ laptop. If I write more than 1GB of data on a NTFS-formatted partition the fans run at full strength. Though, I don't see why anyone would use NTFS. Maybe it is formatted as exFAT and there is some strain because of that? FAT32/VFAT has a limit of 8TB, so I don't see why someone would prefer exFAT.

Yeah NTFS and Linux don't work great together. The problem with FAT32 is the 4 GiB file size limit which can be a frustrating hindrance since > 4 GiB files are quite common these days. exFAT supports much larger files. Personally I use ext4 on all of my storage. I think it is the best choice if you are predominantly mounting it in Linux.

I use a 200Gb sandisk.

Max SD speed & capacity supported by Huawei P8lite? Different sources confuse me!

Can someone provide some insight about this total mess? I got this Huawei P8lite (or P8 Lite? damn hipster names!) and no idea about what faster and bigger capacity microsd card supports!
Android Pit, CNET, Car Phonehouse and XDA says 128GB.
Ubergizmo says 144 GB (16GB+128GB?)
Notebook Check says the specifications are 32GB, but it worked with a 64GB SDXC card.
Phone Scoop says "up to 32GB".
GSM Arena says it supports 256GB.
256GB can be too much space, but I find convenient to use the phone as some kind of HDD and use some syncing tool (Syncthing, Dropbox) to have all files on all my systems and backup online. I'm worried about those slim microusb connectors, something I need to solve
What's the maximum speed this device is able to support? I'm unable to locate it too? Why isn't specified? How to locate it? Sandisk Xtreme PRO has U3 (UHS 3) and supports reads up to 275MB/s* and writtings up to 100MB/s, for example. Can this mobile support it?

Thanks for your input, it's greatly appreciated. What capacity that SD card had?
Yes, it said the same here. I know that's going to be an issue, as I want a massive SD card for different stuff.
Are there someone that casually has big SD cards (128GB+?) and wants to do some tests? What about speed tests?

I don't really use that space. I am fine with 16GB class 10 external SD card(the slow one was class 4 8GB). I don't think this phone can handle 128GB sdcard well since it's a midrange phone. However I can ask Huawei care center about this.

@Suleiman01 i think it should, i have the G play/ Honor 4x (same hardware specs than p8 lite, except internal storage, battery and screen size), and it says max support 64gb, but a 128GB sdcard works too

Then you are right. But it might not be able to handle 128GB+ sdcard. I have emailed Huawei lets see what they say.

Basically it can support all sizes but depends on the file system used. I have a Sony 32GB Class 10 which by default was formatted in FAT32 and i have formatted it to exFAT and it works great on my P8. If the phone supports officially at least 64GB cards then it'll support bigger sized ones because SD cards with capacity of 64GB and up by default come in exFAT file format so this means that it can support higher capacities. Here's the proof
If you are going to buy one then go for the fastest possible or you will have stutters while listening to music and doing some file transfers at the same time. ????

I have a Sandisk 128GB (Obviously formated to FAT32) and works good as hell. All SD cards formatted to FAT32 should work.

What about using EXT4 instead? I use Linux.

Ive never seen a microsd card formatted to ext4. Bigger cards are formatted to exFat which is the formatting that a lot of phones dont support and thats why they say thay they dont support sdcards over xxxGB, but what they actually dont support is exfat. Thats why if you format any size card to FAT32 it will work on any phone regardless of what the manufacturer specifies as the maximum sdcard size. Also ive heard EXT4 is not very nice on flash memories since it wears them out very quickly because of indexing, but I might be going way far here.
Edit: Anyhow linux will support FAT32 so i dont think that makes a problem

@pilililo2
It would be very interesting to know. I know EXT4 provides extensions for SSDs and such since years, but not sure about flash drives (that it seems to use some kind of "HDD emulation in them", right?).
There's this 2010 article about what's the fastest filesystem for cheap flash devices

SDXC cards are mandated to be using exFAT (just like SDHC cards have to use VFAT, and indeed this is the only difference between the two) by the SD card standard. If you don't use this, you are strictly speaking
in violation of the standard and the cards might not behave as designed.
In particular, the card is allowed to only do efficient garbage collection for the access patterns that you get with a single exFAT partition that spans the entire card and has all its metadata aligned exactly in the way that the spec defines.
In practice, things tend to work mostly ok with other file systems, but if you use NTFS or ext3 (rather than ext4), you are usually asking for
trouble.
The best longevity would be provided by f2fs, which is designed to work fine on most SD cards. The downside is that it only works on relatively modern Linux kernels (3.x or higher).
I would expect that cards today use only dynamic wear leveling, not static wear leveling as real SSDs do. This means that content on a read-only partition will decay with the normal life of the card (several years, but depending on the quality of the card and the environmental conditions, e.g. not too hot), independent of the presence of partitions you write to.
Dynamic wear leveling works best if you have a lot of unused blocks, so a good strategy for long life would be to leave a whole partition (e.g. 20% of the size of the writable partition, the more you have, the longer the card will survive) that never gets written after manufacturing, or at least gets erased using the fitrim ioctl command after the initial imaging.
For a 128 GB card with 115GB of actual space, you could then use something like:
* 80GB zisofs/cramfs/squashfs for static data
* 30GB f2fs/ext4 for writable data
* 5GB unused space for wear leveling

You very probably already know that exFAT is totally owned by Microsoft and that there's a leaked GPL-based.exFAT driver for Linux kernel, but this filesystem it's patent encumbered and not merged into mainline.
Why do I mention this?
Because it's a pain in the butt to use it across operating systems and needing to use a custom kernel on your Linux box makes things harder.
I know many custom ROMs with custom kernels use exFAT and very probably even official kernels too, but that's a gray area. Phone manufacturers are able to pay the Microsoft's Android Tax if they want to.

Sooo, what about the bus speed? Is p8 lite compatible with UHC 3 even?
