    Is this an self made SSD?

    appears to be maximum 6X 32gb SDHC cards

    Read 130mb/s write 85mb/s and all in raid 0

    Pretty cheap eh? I think some time back one of our members did the same thing where he put 2 SDHC cards onto on of those SSD-"adapters" for a total for something like 8GBs? At the thing he would have saved like ~$500-$600. It still is a great money saver if you are in the SSD market.

    Japanese website's are really strange looking. I dont understand much of anything on that webpage other than the pictures. It looks like a pretty cool device. It is similar to the dual compact flash to sata adaptors which addonics makes. It seems interesting, but I am not sure that the sd cards will last that long.
    Looks promising though, for the cheap SSD buyer.

    I don't think they are saying THIS device can do those numbers. In fact no SDHC card can do 130/85 let alone a 32GB SDHC.

    It's striping across 6 cards so you can do a theoretical 6x the performance of the individual cards.

    You'd need ~22MB read and 14MB write to get these speeds across 6 cards.

    So for about $400 you have 192GB of SSD. Not terrible, not killer.

    no, if they are in RAID or any other configuration, the speeds don't' stack. You don't get 400MB/sec when RAIDing 4 regular HDD together...

    Yes, you do get (near) linear gains with RAID-0; with the tradeoff that you give up any form of data protection. This is especially true when talking about using solid state rather than mechanical devices.
    Here's just one example.

    You are subject to interface limitations among other things, and your speed gains depend significantly on the hardware/software implementing the array.

    Sounds nice but don't NAND flash memory used in SD cards, USB flash drives have quite limited write cycles? Not really suitable for them to have an operating system on them don't you think?

    Is this by any chance from the Addonics factory? The PCB, component descriptions, colors look exactly like my CF2SATA adapters...

    If you did this you would HAVE to keep a backup of everything and be prepared to ID/swap a bad SD card.

    Yes, those are highly limited...their lifetimes will be very short unless you configure the OS to not have a swap drive, defrag, etc.
