Has anyone laid out the procedure for what to do with a new SD card and WP7 install? I've noticed many posts about it but no one saying exactly "this is what to do". I think this might be why there are so many posts about SD card failures. So if I have a new SD card and an HD2 and I want WP7, what do I do? Thanks ahead of time... Mod if there is an answer to this, I couldn't find it.

If you're just planning to run WP7 (so no fancy dualbooting with Android), there's not much to do, besides backing up anything on the card that you would like to keep. Your phone will create the necessary partitions and take care of the formatting on first boot, if I'm not mistaken.
Not really sure what you mean by "SD card failures". I don't recall reading any posts about that, unless you're referring to the random problems people are having with WP7 and some brands/types of SD cards (not really the result of any card failure).
aye what he said, if you have issues such as lag, wifi not working, random reboots etc then its an SD issue, that means you are out of luck with that current card, . Dont believe anyone when they tell you to buy a spacific card, there is no consistancy in the building of these things so where as you might have issues, someone else with the same card may be fine.i personally have had a wee bit of luck by filling my card with more music
the story is, i had no issues at all with my SD card, but one day after dumping some more music on i started getting reboot issues, took the music off and all was well, then i tried slapping more music on, about 200MB more, and that was it, all is ok again.
its a pure guess, well perhaps an educated guess, but i believe that for whatever reason WP7 had issues accessing a portion of my card, by filling it up some more it prevented WP7 from using it, and thus all is ok again, to be clear, the music played fine however!

That's interesting because I have had the same experience. I have been playing around with multiple size cards and brands. I have yet to get one work right. I have also discovered how you format them makes a difference; for example I have a Patriot class 4 16GB card that using EASEUS to format (low level) it worked but had lag at certain times, for example when going through setup on a fresh install of WP7. It was at a dead crawl with the same config with Android. I then formatted it with Minitool and it was unusable (dead dead crawl) with either WP7 and Android. I also tested a Kingston class 4 32GB w/ wp7 and it was about the same as the Patriot w/ EASEUS formatting. No card I have found outperforms (in the phone) the Sandisk Class 2 16GB card that came with the phone. My suspicion is that the cards that came with the phones have had something done to the sectors by the phone manufacturers. I need to hear from someone who really knows the I/O and Cardbus architecture of phones. My point is there should be a way to get all cards working with any phone, might not be to specs of the card but between tweaking formatting and other hacks they all should work.

My phone came with a Sandisk 2GB card and WP7 has offered me a SD Card Failed message regardless of what technique I have used to Format it...

Lower class sd-cards have way better random reads/write speeds. This means they are better for storing file-caches, system files, and other rather small/scatered files. A higher class card will have awesome read/write speeds, but they do sacrifice the random speeds (they will preemptively load huge chunks of the file they are writing/reading to/from. So, they will have an overhead when accessing a file, that will be attenuated only if the operations made with that file are long. If u wanna write/read a large chunk of small non-sequential file/s, a class 2 is awesome. Which means that these cards are adequate form OS being run from them. Of course, when syncing with zune, you WILL notice a very decreased speed (since the files are being passed sequencially), but the system per se will operate silky smooth.
Hope this helped. Kudos mate

just about to write all of that myself but you beet me too it!
to add to that, no two cards are alike, make and model makes no difference hence my issue with the "working SD card" thread on here, there is no way to know other than trying it
My wee issue is possibly related to some dodgy parts within the card, it reports perfect but if internal components are not consistant it may explain my rather odd situation

In your situation i'd risk say it might have occured some corruption when transfering those musics. At least, considering that all is well now. It is unlikely that a sector of your card is/was permanently damaged, as repeting the operation worked, aye? Also, since I don't know what the file system is used by WP7, I do not know what maintenance the file system requires (such as defragmentation and whatnot)
perhaps, but it is repeatable, if i remove 400MB of music from my device its fine, if then copy 200 on to the card it reboots randomly, if i then copy the additional 200 back to the card it works fine
Potentially your correct, it may be some sign of wear on the card, but either way the music plays fine, which possibly suggests the random access speeds issue again, if it is sub-par sectors on the card that may explain it
Has anybody tried brainmasters mod to speed up the sd card on their MT4G? It looks like he found a way to change the default cache size for reading your sd card. It looks interesting and wonder if it really does speed up the card on the phone. I just wanted to get some opinions before I attempt this on my phone. Anyways here is the link.
http://forum.xda-developers.com/showthread.php?t=1010807
did a test on the stock sdcard and got 3.4 write speed and 126.6 on read. think ill try and report the results to see if its worth it or not.
edit: temp changed cache from 128 to 3072. write speed went up to 4.4 and reading speed dropped to 102.6
says you need to find the right setting to get the best result for your phone, so could be improved a bit.
I tried this (first doing it manually then flashing the 3048 one) it definitely made an improvement when I did it manually but I don't think the flash stuck because it still says 128. Thing is the read still seems better then it was originally but not as good as the manual change.
The one described here: http://forum.xda-developers.com/showthread.php?t=1010807
http://forum.xda-developers.com/showthread.php?t=1021647
Doubled my read speeds. Went from @15 to 30+. Gallery seems snappier. Media Scanning finishes up quicker.
However - Write speeds seem wonky, they vary from 2 to 6 depending on how the phone feels I guess. I don't think the patch is a monumental change, and it makes me wonder why the cache size wasn't increased to begin with since it obviously effects read speeds. Maybe Samsung knows more than us.
Will this not shorten the lifespan of the SD card? There has to be a downside somewhere...
I tried it and it works great. Just make sure after you flash it you check the permissions to make sure it is correct.

It just changes the read-ahead cache on the phone so your phone reads larger chunks of the sd card in one burst. So instead of doing 5 reads (for example) the phone can read 5x as much at one time and hold that data in the cache. That way it doesn't get stuck waiting on the sd card every time it runs through the data held in the cache.
No big downside for this one.
Hey all,
So I'm pretty new to android but have been lurking here for awhile and you guys have got me off to a pretty solid footing. Currently running a S4 (ATT) on Goldeneye Rom with some other little tweaks here and there. Phone runs great, smooth, fast, etc, no problems at all.
I had picked up a Sandisk Ultra 64gb class 10 sd card only to find out it likes to use exFat as its format. After working with CWM and even basic things like music files I saw exFat to not be the most compatible and everyone raves how much easier Fat32 is.
So I made the jump and formated the SD via fat32 Gui tool on windows. It failed a couple of times for reasons unknown to me but finally i got a card with 59.4 gb of space in Fat32, good enough for me, although loosing 4gb is kind of strange.
Everything, like CWM for example, reads perfectly but write speeds are incredibly slow. Using the A1 SD Bench app it reports a 9.32mb/s write speed. Impossible, a 37mb file I copied over took almost 3-4min to complete.
Any point in the right direction would be greatly appreciated. Might just have to go back to exfat
Thanks.
Edit: Slightly after this post I ran the benchmark again, write speed at 2.93, thats more believable.
I'm testing SD card speeds/rates on Note 10+ (512GB, Exynos) with Androbench. The same way as I did for my Note 9. The results go into the same google sheet as the old ones. As of this moment, it is mostly Work in Progress... and it should get some LG results, too, some day Soon(tm). I'll hopefully get most of the Note 10+ stuff done tomorrow.
Sheet here: https://docs.google.com/spreadsheets/d/1rs8S2yreJYYms6ik8NgoGagZ_6OKrU5bu1FotHJVz6g/edit?usp=sharing
Preliminary results with only 3 cards tested: seems my Note 10+ is getting even slightly slower results than Note 9.
Lucky me, it seems I won't be using an SD card on this phone; I got the 512GB model so there is plenty of internal storage, and I might end up using the slot for second SIM. (And the Note 9 will remain in use for video recording, due to needing 3.5mm mic input, which seems to be a no-go with the Note 10+ for the time being... So I won't be even needing much of that big internal space on the N10+ anyway.)
Feel free to add your own results in this thread, like done in the old thread for Note 9, I'll copy them to the sheet. Please remember to specify the particular Note 10+ model (i.e. which SoC), its state (which firmware and version, rooting/scheduler tweaks/etc.) and which card (preferably with specific product code / SKU, as namings are often ambiguous (due to manufacturers reusing the same name for different card tech/generation/whatnot, see how I record them on the 'extras' sheet).
Here is the Note 9 thread for reference: https://forum.xda-developers.com/galaxy-note-9/help/note-9-sd-card-slot-speed-rating-t3833981
EDIT: All the significant tests are done (need to clean up the sheet, still). Most cards behave relatively the same way as on Note 9, i.e. slower card is still lower, with roughly the same proportions. But there are couple notable differences. Especially Lexar 633x 128GB managed to squeeze a higher random write rate (yet is otherwise slower just like other cards). The UHS-II 3 card is still utter crap (with decent sequentials, which are comparable to good UHS-I cards) - i.e. even this flagship phone still doesn't work with that better interface, but only with UHS-I.
And indeed almost all results are slightly down compared to Note 9 results. Since there was a random good peak sequential result among everything, it makes me think the system could do better, if the firmware was working better for this use case. Perhaps, e.g., the scheduler/CPU state management and Androbench combination somehow has timings which end up mostly keeping the work on a slower core and/or in a slower state, and the result is unnecessary delays or such. And the random high score could be explained then by a random higher-demand process keeping the CPU at better state for a moment, Androbench benefiting from it as a side-effect. All that is just speculation, of course. And it does not affect the end result: most users may see less than flagship level card performance.

Judging from those numbers, I think you forgot to switch the test target to the card in the settings; it measured the speed of the internal storage, which is indeed reeeaally fast.
Oops feel a tit now haha just added it again
Here is mine. Samsung 512GB EVO Select (U3) 100MB/s
Galaxy Note 10 Plus 5G Verizon
My Note 4 pretty much gives the same results. 82MB/s seq R, 54 MB/s seq W, 9.9 MB/s random R, 2.8 MB/s random W.
This is with SanDisk extreme UHS-I A2 256GB. I wish they made the card interface faster as everything else gets faster!!!
Hi guys, just found this topic and tested my card in Note 10+
It's weird, I have high read speeds but very slow write speed. Have Samsung EVO Plus 128GB.
OP, I think you may be missing the whole point of using a data drive, its primary purpose is to retain critical data. It read speed is somewhat critical in that you need to be able to play music and vids from it with no glitches. The 10+ with a V30 rated card is well capable of that.
Data drives should never used for running apks.
Internal memory should never be used for critical data storage; only the OS, loaded apks, temporary folders and the DCIM folder (for temporary holding until transferred to data drive).
Temporary folders/vetting data before it goes onto the data drive is important, use the download folder for this. Open any downloaded images in the download folder before transferring to the data drive. A malware jpeg will do far less damage here than if it gets on the data drive! I've had a malware jpeg that effected the Android OS, they are real. Generally their rein of terror is confined to the folder they're in, but not always especially if you unwittingly move it!
Scan anything questionable (especially apk downloads)with online Virustotal.
Any downloads not recognized, delete without opening! Trojan preloaders will sometimes get by the browser and autodownload in spite of settings. Look at the download folder daily for crap that don't belong. This happens very rarely but it's of paramount importance you nip it in the bud.
Everything you need for a full reload including installable app copies, backup setting for all apps that support it, any passwords, all critical data that is on the phone goes on the data drive.
Back the SD card up redundantly with at least 2 hdds that are physically and electronically isolated from each other and the PC. I use more than 2 hdds including a .5tb OTG flashstick. Stagger backups when possible to help limit the possibility all will be compromised by a malware file.
Using the SD card as a data makes the phone more secure and secures your critical data better. Makes backups and reloads much easier.
Done right no PC, cloud crap or internet is needed for a full reload/restore. Plan ahead and develop a plan that protects and preserves your critical data or you will lose it eventually. Plan ahead for a factory reset so it goes fast and seamlessly to a fully restored phone with little or no data loss.
Currently I'm using 68 of 512gb internal and 344 of 465gb on the SD card. Will be upgrading to a 1tb card soon.

I agree with blackhawk. I have owned Samsung Galaxy devices, including SM-N975F 256GB/256GB since S6.
I store my CD audio on the SD, and I also store my backups of my phone there.
If you end up somehow clobbering your OS and need to restore there is no better way than having a backup that is easily available!

Exactly. I just upgraded from a .5tb to a 1tb V30 SD card on my N10+.
These speeds are real usage and more then fast enough to use as a data drive for streaming vids, whatever.
Internal copy times:
Old .5tb card (read speed)
SD card > internal memory [email protected]
New 1tb card (write speed)
Internal memory>SD card [email protected]
Both cards are V30 Sandisk Extremes.
N975U running on Pie.
The N10+ is a snappy fast device with exceptional capabilities if used correctly.
By comparison the new Samsung flagships suck.
My other N10+ N975U1 it came factory loaded with Android 10, neither one will be upgraded.
Sandisk Extreme V30 rated, 1tb:
