    I recently picked up 6x Samsung SM843T 480gb SSD's, and thought I'd give them a review, since they're extremely affordable for what they are, and a few people jumped on them when I posted the deal.

    My system configuration is as follows:
    Dell R310 with X3430 cpu & 8gb ram
    Dell H800 HW raid controller with 1gb cache
    LSI 620J DAS

    Through research I've managed to learn that the drives are already 17% overprovisioned from the factory, so the 480gb SSD's are actually 560gb SSD's, leaving room for garbage collection.

    So far I've had zero issues with the drives, considering I bought them used. 5 were like new, one had some use, but still had overall good health. Here's hte smart data: 6x Samsung SM843T 480gb Enterprise SSD's

    Under Windows storage spaces Parity Array:

    Under Perc H800 1gb cache controller configured as raid5:

    Single Intel 730 series 240gb SSD performance:

    IOPS when using Raid5:

    IOPS of the Intel 730 series 240gb single drive:

    If anyone wants other tests run I'd be happy to run them before i move to production.

    Enabled the H800's Cut-Through IO, and re-testing.

    Here's raid5:

    I can't even finish these tests. Cut-through IO in this application is bad.

    For those that are curious:
