Now I know I've seen posts that mention small block write speed as being important, but the numbers I've seen posted really didn't make me think the Patriot was the cause. The other is a Kingston Class 4 4gig that tests out as significantly slower than the Patriot, but didn't really run froyo any slower. One of those is a Class 10 Patriot 8gig, which I've seen mentioned as an acceptable boot disk. Over the last couple of months as I have mucked around with SD booting various flavors of froyo and, more recently, CM7, I have found it maddening that there are apparently so many people that LOVE those versions, even people that seemed to have the same SD card as the two I've tried. Thank you a.fenderson!Īpril minor update with a Transcend SD (see ) update: Thanks to waxhell for compiling all of the results in this thread (at least as of mid-december! OK, so I took a while to get this posted.)ĥ/20 update: SD card performance benchmark table by a.fenderson from later in this thread added at the bottom of this post. I'll have to wait til Monday to try it our since I'm currently not able to access the internet at home. Curious about that but it seems I have a winner for CM7 on SD. The first test I ran on the Random 4k QD=32 got me 1.5MB/s write. Now these numbers seem to change for me depending on the test. Random Write 4KB (QD=32) : 0.607 MB/s įor those looking for a specific place to purchase a card instead of hoping an praying that the one you find at your local B&M will work like I have been (up to 3 16GB cards right now 1 good 2 bad for CM7 on SD), this card right here: SanDisk 32GB Class 4 (brand new, got off eBay) SanDisk 16GB Class 4 (brand new, just purchased) SanDisk 16GB Class 2 (at least 2 years old from my phone): I'm really enjoying the Nook w/ CM7 on it. Thanks for the info in this thread and this forum. I tried "sudo dd if=/dev/sdc if=/dev/sdd/ucenter.img" hoping to rip the card to an image file on a USB drive but it didn't work saying something on the order of the file wasn't present. img file off that card and move it to a SanDisk 16GB card with the "dd if=/" thing but can't figure out how to do that in Linux. I was wondering if there is a way that I can rip the. I also have a Microcenter 16GB Class 4 that works fine except for the web browsing thing. Any ideas? Should the cards be formatted first or will this work as long as there is free space on them? There is little info in the help file or online as far as I can tell. I'm right clicking on both the 32 bit and 64 bit versions and run as admin in Windows 7 64bit on my laptop w/ the built in SD card reader and an adapter. Each time I try it says that "Failed Create File". I have a very stable 8GB SanDisk Class 4 but can't get the CrystalDiskMark 3.0.1 to run.
