    (Explicative of your choice here)!!!

    Check these numbers out:

    Wrt32bit: 2266
    Wrt8KB: 936228
    Read8KB: 3276800

    Keep in mind this is an empty card. Let me copy my data back and get some real world numbers.

    Was this FAT32 without a backup FAT? Did the numbers hold up for repeated tests while it was an empty card? I saw that the filled card tested out like before ...

    Just to complete the picture on the cards that I tried, the Transcend and the A-Data (I got a replacement A-Data which worked reliably after having first received a flaky A-Data). Both cards tested out in the same range using CardSpeed:

    4GB Transcend x150 Fat32 (32K clusters)
    ----------------------------------------
    Wrt32bit: 18-24 bytes/sec
    Wrt8KB: 36817-48455 bytes/sec
    Read8KB: 3276800 bytes/sec

    4GB A-Data x150 Fat32 (32K clusters)
    ------------------------------------
    Wrt32bit: 18-23 bytes/sec
    Wrt8KB: 36561-45829 bytes/sec
    Read8KB: 3276800 bytes/sec

    However, when using VFSMark, I got consistently better marks (in the areas I care about) from the Transcend:

    4GB Transcend x150 Fat32 (32K clusters)
    ----------------------------------------
    File Create: 120-121
    File Delete: 92-93
    File Write: 16-17
    DB Export: 77-81
    DB Import: 122-129

    4GB A-Data x150 Fat32 (32K clusters)
    ------------------------------------
    File Create: 72-75
    File Delete: 42-44
    File Write: 11-16
    DB Export: 42-51
    DB Import: 118-129

    So, at least for me, the Transcend is the better performing card.

    TOPRAM 4GB SD (Ebay) advertised as 150x:
    (Since returned)

    Write 8KB: ~55KB/sec.
    Read 8KB: ~3.2MB/sec.

    Reformatted with 32K clusters:

    Write 8KB: >200KB/sec. (empty)
    Read 8KB: ~3.2MB/sec.

    The CardSpeed rating was "excellent." So why did I return it? Using Audacity (an audio recording from the makers of CardSpeed), the real world performance of the card was inadequate. The audio recorded on the card skipped--like a slow card would skip regularly. (This is the purpose for which I needed the card.) I got similar results with a reformatted slow 1GB card.

    Can we trust these numbers? Anyone else do any real world audio write testing?

    (BTW, for dictations, I use an 4-5 year old 64MB SD card that has seen a lot of use. Standard formatting yields "excellent" results:

    Write 8KB: ~165KB/sec.
    Read 8KB: ~1.7MB/sec.)

    Lastly, the writeup on optimizing card speed in ERicJ's post mentions a bunch of formatting tools that allow you to block the creation of the "Backup FAT", but they all seem to be for PocketPC. Does anyone know of any Palm-based or even WinXP-based utilities that could do the same trick? I'd like to find out if that possibly helps speed, on the Palm side as well.
    I was wondering the same thing.

    So, does anybody know how we might go about disabling the creation of the "Backup FAT" if we don't own a PocketPC?

    Can someone confirm if the Transcend comes stock with 32k clusters? If it doesn't...Mac tool to reformat and adjust clusters?

    You'll have to get down down and dirty with the command line interface, but newfs_msdos has everything you need, including clustersize, and disabling the fat backup.

    I'm currently formated Fat32 w/ 32k Clusters.
    I have the Ridata 4GB PRO 150X
    Wrt32bit:24 bytes/sec
    Wrt8KB:46479 bytes/sec
    Read8KB:2912711 bytes/sec

    Does disabling the creation of the "Backup FAT"
    really make a diff w/ these 150X Cards?

    Not nearly as much a difference as reformatting with 32K clusters. I only saw about a 5-10 percent improvement by disabling the backup fat table. Whereas the move from 4k to 32k clusters was orders of magnitute faster.

    any experiences with OCZ brand? they're pretty cheap at outpost dot com

    My ideal is to have programs on the card load and close at speeds that are as similar as possible to programs on the palm main memory.

    Out of the posted metrics, obviously the Read8Kb metric is important for program loading, but what about when programs are saved back to the card?Wrt32bit or Wrt8KB?

    SanDisk Ultra II at 2GB is ten times faster than the 4GB cards at Wrt32bit, but is that significant for using LauncherX and PowerRun?

    I'd like to move to a 4GB card, but not if my day to day programs will load slower.

    Currently there is a real tradeoff between performance and capacity between the 2GB and 4GB cards. For those of us that need the extra capacity, there are ways to make the speed more tolerable, but there is no way to get a Trancend card to perform at U2 or U3 speeds. Being that performance is you primary criterion, I would go for the fastest 2G card that you can get.

    One note. The 4G cards that are available today are no longer made. For capacities larger than 2G, the SD card allience has deemed fit to make a new incompatible standard called SDHD, which is not compatible with any currently shipping or announced Treos. (I'd imagine the 800 series phones will support SDHD, but they haven't been announced yet).

    One thing to note. On the 700p I have enough room to install all of the applications that I need on a day to day basis with 37MB to spare. I only use the SD card for storing data. So the performance is bearable. (I don't use Zlauncher anymore, because the 700p has enough internal memory)

    some of this info is over my head but if i am interested in getting a 2gb card, which would the winner be? looking for card primarily to run tomtom6 on, for my treo 700p

    Hi all,

    I'm looking for a fast 4GB SD card for my new Treo 680 (upgraded from a 650).

    I bought an A-Data 4GB SD 150x card a couple months ago, but now that I'm using it in my Treo 680 the write speeds seem rather slow compared to my old Panasonic 512MB SD card. My A-Data 4GB card is formatted with 32kB clusters.

    Is there a faster writing 4GB standard SD (not SDHC) card available that I can use in a Treo 680? Thanks!

    Speeds from Card Speed:

    A-Data 4GB in Treo 680:
    Wrt32bit: 15-22 bytes/sec
    Wrt8KB: 32244-34813 bytes/sec
    Read8KB: 2912711-33276800 bytes/sec

    Panasonic 512MB in Treo 680:
    Wrt32bit: 82-154 bytes/sec
    Wrt8KB: 129134-238312 bytes/sec
    Read8KB: 2912711 bytes/sec

    Panasonic 512MB in Treo 650:
    Wrt32bit: 98-152 bytes/sec
    Wrt8KB: 164870-281875 bytes/sec
    Read8KB: 2383127-2621440 bytes/sec

    Thanks!

    Based on this information wouldn't the best way to format the SanDisk 2gb Ultra II be 4k clusters?

    Code:
    C:\Documents and Settings\Dad>format /FS:FAT32 /a:32K F:
    Insert new disk for drive F:
    and press ENTER when ready...
    The type of the file system is FAT.
    The new file system is FAT32.
    Verifying 1937M
    The specified cluster size is too big for FAT32.
    When I tried formating like you stated with FAT32 32k clusters that is the error I got. Used the regular FAT and 32k and it formated correctly? Did I do something wrong?

    No one has any more info on this?

    I get the same message when I attempt to format both a 1GB Transcend 80x as well as a 2GB ATP Pro 150x.

    does this speed test work on SDHC cards or just SD cards?

    how do u format the card on the treo?
