32GB SD cards

[iofthestorm]

Anyone using a 32GB SDHC card in their Fascinate? Just asking because there's one on sale on the Newegg Shell Shocker later today (check at 10AM pacific time). Wondering about speeds and such, and whether Class 10 is worth it (seems like if you want to fill such a big card, it'd be nice to have the faster write speeds of Class 10 but I've seen some reports of incompatibilities/problems with C10 devices).

I was just benchmarking the card that came in my Fascinate (which is supposedly Class 2) with SD Tools and I get 5-8MB/s writes and 16-18MB/s reads which is way better than the Class 2 minimums. The one on the shell shocker is a Class 4 so I'm just wondering whether it'll be a downgrade in terms of speed (just because it's rated for significantly lower speeds than what I'm getting with the internal one). I'll probably end up getting it anyway because I've got ~1GB free on my current one and I want to play with an Ubuntu chroot install.

i got the sandisk 32g class 10 it was worth it. Seems to R/W faster but that maybe due to the SD card boost read ahead cache hack. I think mine is set to 512K. Whether its faster or not the extra space is always a plus

Guess ill find out the hard way with ya, bought one as well. Was also wandering about the speed difference. Noticed the one that came with was class 2 and the 32 was class 4, hoped it at least wouldn't be any worse as i am content with the speed of the included sd. Was really surprised to see that it was a class 2.

Oh well just have to wait until it gets here and see.

DO NOT BUY THE Patriot LX Class 10 32GB CARD!!!

After a few months of light usage (i hardly ever connected it to transfer anything, just had HD seasons of breaking bad, chuck, human target and sparta that I never had time to finish watching) I finally hooked it up for maybe the 6th time since i purchased it, and after transferring some music and more shows, i got a "Damaged SD Card" error. For the last month since that occurrence, I have had to reformat the card at least once a week, and set up my music and just a few episodes at a time (because whats the point of putting seasons on if i'll just have to transfer them over again in a few days) consistently. Sure, it moves along at 12MB/s, but certainly not worth the hassle.

This is not an issue that I have heard of with Class 2 or Class 4 32GB micro SDHC cards, and Patriot says they are working with Microsoft and Google to determine the cause of the issue, but Newegg reviews indicate that this is not an isolated incident.

Good luck with the SanDisk card!!!

Mhm, I got the A-Data 32GB class 4 from Newegg. I benchmarked it and it's not as amazing as the built in card (around 5-6MB/s write and 12MB/s read) but it's not super slow. Yeah, I ended up avoiding the Class 10 cards for that reason actually. It's nice to have so much free space now; I think I'm going to try installing Ubuntu in a chroot jail again.

The new PNY class 10 for tablets is now in stock at Newegg, just ordered one with free shipping.

I got this exact card -- Just arrived yesterday.. I am getting AWFUL performance from it. I mean it performed like 3MB/s write and 8MB/s read.. It only fluxuated by about +-1MB with various SD read_ahead changes.. So disappointed. The worst thing is my phone is NOTICEABLY worse-off with the card in (weird stutters, etc).

Which leads me to something else altogether -- Has anyone noticed that with no SD card in the phone it just flies? I mean even the old SD card which didn't SEEM to give me any stutters was a matter of night and day with it in our out.

jt's CM7 Test Build 10 / EC09 radio / OBT .13 kernel @1400mhz
Old radio was EB01.

_______Update________

So I hadn't tried the card today with the EC09 radio (why should it make any difference?). It seems to have made a difference. Below are my results (with SD Booster app to change Read Ahead value, and AnTuTu benchmark just doing SD Card IO).

PNY 16GB MicroSDHC P-SDU16G10TEFS2

Read Ahead, AVG Write, AVG Read
4096, 6.4MB/s, 15.4MB/s
2048, 6.5MB/s, 15.4MB/s
1024, 6.5MB/s, 15.5MB/s
512, 6.0MB/s, 16.1MB/s
256, 7.4MB/s, 16.3MB/s
256 (2nd pass to verify), 7.4MB/s, 15.9MB/s
128, 6.9MB/s, 14.8MB/s

FAT32 / 16GB Partition

I hope this helps someone. Still not sure why my write speeds are so slow on Android when I've seen them hanging around 12MB/s in Windows (When using FAT32).

Patriot has a lifetime manufacturer warranty on most of their memory. You should contact them about getting a replacement. I run their RAM on my custom built personal pc. It is super stable. Just hoping to help.

I've used both the Patriot class 10 32gb card and the wintec 32gb class 10 card. Both have corrupted my data after a few days. Heard the sandisk and the lexar cards are good, so you may want to give them a shot.

Got the scandisk class 4 32gb and it's satisfactory

i was just about to buy a larger card when stumbling onto this post.
Does the read/write speed slow down as the card gets bigger in size?

No, but I have found that cheaper/nonbranded cards tend to be slower. Read reviews before buying.

I've got a lexar 32gb class 10. It's absolutely terrible. It takes so long for pictures from the gallery to load after you take a picture for example. Anything using hte SD card is slow as molasses. Oddly every benchmark I throw at it shows high speeds, so I have no idea what is going on with it.

 

[tulalhyt]

may be could try this (get rid the lba) could help the perfomance and compatibility ?

try read this thread (hope help), I'm not try it my self on my fasci, since my class 10 msd still on it's way send to me.
