Extreme Speed Streak - 45mb/s

Hello to all Streak owners
I've just bought a Streak that requires a new screen, and whilst replacing that I will be looking into replacing / upgrading the 2gb internal Micro SD card.
Now I've read some threads on here and believe you have to set it up correctly as it only recognises 2gb at a time, but thats not my query now, I'll find the info and if not then I'll post for help.
Q)
My question is with Micro SD cards getting ever cheaper, and faster, higher performance ones dropping also in price, is it worth going in for these faster, higher performance cards???
Either for general Micro SD storage or internal storage, replacing the 2gb.
I know it seems common sense, by putting a faster or higher performance card in, should make it faster. But...
???)
Can the Streak make full use of the higher performance, faster cards?
When do you reach the point of overkill, or diminishing returns?
Can the streak support higher speed technology? (I believe I read somewhere that in fact the lower class cards were faster, although I don't understand this) If this is correct, someone please explain...
Ideally I'd like to know what is the fastest card the Streak can make use of? And what Micro SD technologies it can support?
Also if anyone has real world speeds for cards, (as I understand, often the numbers, classes manufacturers quote often mean nothing, compared to how they actually perform) or preferred manufacturers they could recommend, or links to tests, benchmarks, reviews etc.
Many, Many, Many thanks to this site and all its contributors,
I've used this site for many years, back when I had an XDA II from O2, lost / forgot that username, then again when got MDA Tmobile, AKA (Blueangel), but I don't post much as usually I'm able to find what I want, buy searching on the site or by xyz or whatever I want site:xda-developers.com in a popular search engine.
Best wishes and Seasons Greetings to you all,
John

Keep this in mind: at a certian point even if the card is compatable, the controller on the device itself will eventually be the bottleneck. Would this be the case? I have no idea, but adding in a faster card then the stock one has shown benefits.

differences in running micro sd class 6 and 10

Hello,
currently, im running a class 6 micro sd card in my hd2. Now, if i replace the card with a class 10, is there a boost i would 'feel'? Or is there no real difference in performance, only on paper?

Normally, no. You'll feel difference only when copying very big files over long time(say large movie over card reader as HD2 hardware bandwith is also limited). For normal, everyday use SD 4 or 6 class is the best choice.

I'm using a 32GB Class 4 SanDisk (partitioned into two 16GB chunks) for my WP7.5 and Android. SD Android builds do tend to seem laggy at times.... is this expected?

Yes. Some SD builds are faster than others, though NAND Android is always superior to SD builds.
Also keep in mind overall Android speed is determined by random access, not sequential(micro SD class!) write/read.

in my experience, the class label placed by the manufacturer is misleading.
the class rating doesn't really talk about maximum speed. instead, it talks about the minimum guaranteed speed. it is best to read benchmarks before you go for a particular sd card.
for example, i used an 8GB sandisk class 2. this means that the card can at least demonstrate class 2 performance. in practice, it was FAST!!! gave about 10+MB read speed and about 7+MB write speed.
then i got a 32GB kingston class 4. this means that the card can at least demonstrate class 4 performance. in practice, it was slower than my previous 8GB sandisk. got about 10+MB read speed and about 3+MB write speed.
so, in conclusion, no one can reliably tell you if a particular card model will feel faster. like others have mentioned, there are already complications like differences in nand and sd and even differences between two seemingly similar nand builds, for example. when we talk about comparisons and observations that YOU will perceive as a result of your purchase, we are really talking about what improvements (or lack of) you will feel in comparison to your existing card. and all we can tell about your existing card or the one you intend to get is the misleading class label on the card.

Thx for the info guys!
NAND Android is always superior to SD builds

Which leads me to another question...
Does anybody know numbers about the performance differences between SD and NAND builds? SD builds differ in speed, retsam88 already said that, but are there some rough numbers?
Are there devices which are known for fast/slow NANDs (or other significant characteristics)? Or are the NANDs identical in every device? Maybe a link?
Sorry for asking stupid questions but I'm pretty new to the customROM-stuff and also want to get some technical background knowledge before diving in in october with the studies .... again, thanks in advance!

Since I had my HD2 like months ago I was always using SD-Roms cause their easy to use via MagLdr & I thought the speed was OK but as you go on using it it becomes laggy...
then I tried an AOKP NAND & there was a significant difference in speed, so now i'm stuck in using NAND Roms., BTW my SD card was a Class 10 type :silly:

Those are very interesting questions must say
As for differences, I'll give you my personal observations:
-Booting up system is both fast on SD and NAND builds.
-Stability is superior on NAND(because SD can corrupt badly if used incorrectly)
-Installing apps is way faster on NAND(say, 15-60sec improvement)
-NAND got limited write/read cycles(a lot though) so SD builds keeps HD2 healthy longer.
-games running on NAND android seems to be bit faster(depends, sometimes 1-3FPS more, sometimes hell of a lot 20FPS+)
As for NAND speeds, HD2 was manufactured by mass scale, so NAND speeds seems to be relative similar with every device. With microSD you got many manufacturers, big companies, small companies, fake companies so results differ a lot. Also SD cards tend to get replaced faster.
Also feel free to ask further questions.

Cool! Thanks again for sharing your knowledge

awww yeeeah, prepare
I hope it's ok, also with an eye on the moderators, coz the thread title is pretty misleading now
Is there a way to replace the NAND?
If so, how much does it cost and can you replace it yourself?
Are there some smartphones/tablets without NANDs?
Which phones are known for having big/small internal storage space?
Which one is more resistant against magnetic influences: NAND or SD?
Beside microSD, are there any more relevant card types used in mobile devices?
If you look towards future, any changes (especially hardware) coming soon? like card type changes, notably increased NAND speed/storage space/
A lot of questions I know, just curious, if you guys know answers, don't hesitate to post ))
and thanks again!

Actually NAND is a way of storing information, both internal HD2 memory and SD cards are built with NAND. We just call HD2 internal memory in short- NAND. NAND is very resistant.

Not much other than microSD, though I saw some smartphones using compact flash mem.

Yes, in short, SSD tech in smartphones.

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?

Why wouldn't it work?

I actually am not bothered by lack if sdcard support as long as bigger storages wont be overpriced like hell. Anyways personally, for me speed and responsivness > sd card support

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:

It was supposed to be a joke.

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.

[Nexus 7] Feasibility of replacing or upgrading Hynix HTC2G83CFR DDR3 RAM

Hi!
Having dug my old Google Nexus 7 2012 out of storage and found it both working and happy in terms of battery lifetime I let my mind wander towards fixing what I consider the main flaw with the device: Its 1 GB of system RAM.
Now, I have my fair share of microsoldering and idle work in BGA soldering and the like but my software hardware is far more lacking. I already know that the Nexus I have holds 4 x Hynix 2Gb HTC2G83CFR DDR3L RAM and the datasheets for it these are fortunately available, I also know that the Tegra T30L chipset supports up to 2GB of RAM. The closest I've been able to scrape together sofar are Hynix 4Gb H5TC4G43MFR but these use 78ball FBGA and 96ball FBGA, but atleast I'm on the right track in finding older chips...
This is where I run into the software knowledge lack; Simply finding fitting chips to replace the old ones and successfully soldering those on will not neccesarily just work out of the box? Depending on the kernel it might detect and make use of the new chips but it might also not.
Am I right in assuming that there will be a need for software side hacking to accomodate the upgrade?
On a sidenote I also found Daniel Sauvageau's musings on doing the exact same thing back in 2016 but there are no follow-ups to it. He does raise a concerning potential roadblock in his article on the matter:
"Find out, preferably in a non-destructive way, whether A15 is actually routed from the SoC to the DRAM BGAs. Without A15, I would need DDR3L DRAM that has 2KB pages instead of the typical 1KB ones found in all eight-bit-wide chips I have looked at. If neither are possible, then this idea is as good as dead"

Any thoughts, ideas or inputs are welcome!
(Yes, I am aware that this is neither particularly economical nor for the faint of heart lacking a decent way to reball BGA)

[nVidia Shield Pro] Increase RAM and eMMC

Good evening.
Was looking at my Shield Pro 2019 sitting on the shelf, and an idea popped into my head; would it be possible to upgrade RAM and eMMC chips? I have no particular reason for this, besides pure curiosity.
I've got access to professional solder equipment, including rework stations capable of desoldering BGAs, xray equipment to inspect said BGAs and about 20 years of experience with soldering and reworking complex circuitry.
If I'm not mistaken, RAM chips are either Micron, Samsung or SK Hynix and the eMMC chip would also likely be supplied by either Micron or SanDisk.
So, disregarding the physical job desoldering/resoldering chips, are there any software issues that must be taken into account?
The eMMC would of course need to be flashed and repartitioned if upgraded to a larger size, but would the RAM chips require any software modifications after swapping them out or would the system simply accept a larger RAM size out of the box?
I've Googled a bit, but couldn't find any concrete information on what changes would be required on the SW/FW side of this.
Best regards, Tim

Unfortunately, this looks like one of those things where ripping it apart and doing the do would be the way to go. Maybe the least "invasive" thing to do would be a RAM upgrade, provided compatible chips of higher capacity are available. Theoretically you wouldn't need to touch anything on the OS side for a bump in RAM capacity. I think the Tegra X1 supports a maximum of 4GB of RAM and the X1+ supports 8GB - allegedly. I suppose the memory controller is built into the SoC itself so there's no tampering with that.
I don't know anyone crazy enough to do that for me... nor am I really willing to apply my very amateur BGA soldering skills on a device like this one.

Both was already done on Nintendo switch (also tegra X1/X1+)
Emmc is the easy part, ram is possible but you need to know which ram are supported.
