SanDisk Ultra II Plus USB

Our final entry from SanDisk isn't exactly a USB flash drive. Instead, it is a SD card that has a USB interface directly on the card itself. The drive can be used both as a SD card and as a USB drive. Obviously here, we are more concerned with it as a USB drive.

To reveal the USB connector, you simply push the rear part of the SD card down and that part snaps away, revealing a USB connector. Much like the I-Stick's USB connector, there's obviously no metal surround, just the actual USB contacts themselves mounted to the plastic card.

Unfortunately, because of the nature of the card/drive, it actually feels quite flimsy. So although the form factor is nice, it isn't as solid feeling of a drive as PQI's I-Stick, since it is made of multiple movable pieces.

Obviously, this drive is more for users who have a camera or device that can use a SD card, as it makes for an easy way to get the contents of the drive onto a computer without worrying about finding a reader.

    Do the read and write speeds change for the 1gb and above models? Would I get the same performance, or should I stick with the 512mb? Reply

    what kinf of benchmark are you guys using? How come some of those drive write speed is sooooo low!? Like Trenscent, OCZ Rally, i've seen some reviews out there which says other wise. Reply

    here's the review by tom's

    if you look at the trenscend jet flash, it actually has the highest write speed average out at 23.3 mb/s vs anandtech's 8.7 mb/s !? what the hell?

    It looked like Tom's test is testing the write speed between USB host and flash drive's controller's memory buffer, instead of actual write speed, which can only be verify by doing a read after writing is completed. There are also reports that http://www.auphanonline.com/articles/view.php?arti...">cluster size may affect the write access behaviour. BTW, Tom's http://www.tomshardware.com/2005/08/10/two_fast_an...">later review has simultaneous reads and writes benchmark, which slows Memina Rocket to a halt. Reply

    In addition, even when using buffered write in SiSoft Sandra, it is extremely unlikely that Transcend Jetflash 110 can write anywhere near 23.3MB/s. http://www.oc.com.tw/article/0510/readparticle.asp...">This benchmark shows that when doing random write with Kingston DataTraveler ELITE, write speed dropped more than a half compared to sequential write.

    I'm the in-house support for a university building and I've had absolutely horrible luck with Lexar drives. Lexar often fails to detect entirely on somewhat older machines (the Latitude C840, for example) and has also displayed a relatively high failure rate for me. I don't have any positive or negative impressions of Kingston drives, so I can't say anything there, but I will say that I've had by far the best luck with Sandisk drives. I've never had one fail on me, and I've seen them go through wash cycles, get run over by a car, and get left out in the rain. Compatibility has been universal as well. They may not be the fastest drives but they really are the only ones I've ever trusted. Reply

    i work for a flash memory controller maker and in all honesty the most meaningful performance test is random write. and no one really advertise that since sequential read speeds seem much more appealing and marketable. i can get a dual-channel & interleaving enabled usb 2.0 pen drive with micron or samsung nand-type flash to go up to 34mB/s in sequential read, but the engineer who designed this still tells me that he'd rather use and-type flash from renesas (formerly hitachi) since and flash has a better random write than nand flash.

    and knowing what i know, if you use your pen drive very often, and i suspect some of you may be in that boat, i'd check out some of the burn-in testing results especially since companies are not entirely using only samsung nand flash. certain new flash whether nand-type or ag-and-type and even some high-density samsung flash seem to be displaying a need for extra care in ecc. data-verify errors are fatal, especially if it's the only copy you got...

    anand, perhaps a little visit to some of the design houses for these controllers the next time when you're in taiwan is in order. computex is only 9 months away.

    Although not reviewed here, I got the A Data key from newegg.com simply because they say it works with Linux on the package. I know any key will, but they are the only ones to have the guts to say it. Thanks for admitting Linux exists. Lifetime warranty too. Reply

    here is a link for another link, to an app that can make many (but probably not all) usb drives bootable and a couple of other hints/tips.

    O.T. - for some reason i get a message that says i do not have permission to access this forum when i tried to create a new login with my e-mail address. did i get banned or something? i have only posted once (it was about the gta:lcs website). i also cannot log in with the origianl user name and password.

    p.s. - it is o.k. to post links like this right?
