    Does anyone yet make a .8TB to 1TB Flash memory in a 3.5" drive physical
    format. Or other physical size that is fairly dense. If so, could you
    pass on a reference? The interface would need to support about at a
    400MB/s sustained rate. I can work with any interface such as Fiber
    Channel or whatever .
    thanks for any tips

    How about Solid State Hard Drives ?


    or an I-Ram / I-Ram2 / Hyperdrive ?, these all use DDR Ram.

    Here is an SSD with a PCI Express x8 interface.
    Sustained write 600MB/sec. 10000 IOPS. 1TB capacity.


    Listed as about $4700


    I think inside the box, you'll find four SSD drives and a RAID controller with cache.

    This one appears to be built as a drive mechanism, and is available with
    different interfaces. The IOPS rating is higher. But the sustained write
    rate is too low. Perhaps two of the 2.5" ones in RAID0 would do, using
    SATA 6Gb/sec interfaces.


    So at least that gives some idea as to whether it can be done or not.
    It may require you to do some RAID0 magic, to get what you want.

    A couple of these RAIDed, might come close. 2 x 220MB/sec on SATA 3Gb/sec interfaces.


    Just a matter of finding one that fits the box you're trying to stuff it in.
