ATTO Disk Benchmark

The ATTO Disk Benchmark program is free, and offers a comprehensive set of test variables to work with. In terms of disk performance, it measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. There are some minor improvements made to the 2.46 version of the program that allow for test lengths up to 2GB, but all of our benchmarks are conducted with 256MB total length. ATTO Disk Benchmark requires that an active partition be set on the drive being tested. Please consider the results displayed by this benchmark to be basic bandwidth speed performance indicators.

ATTO Disk Benchmark: Queue Depth 4 (Default)

Our bandwidth speed tests begin with the OCZ Vector 150 solid state drive attached to the Intel P67-Express SATA 6Gb/s controller operating in AHCI mode. Using the ATTO Disk Benchmark tool, the test drive performs basic file transfers ranging from 0.5 KB to 8192 KB.

The 240GB model provided to Benchmark Reviews for testing produced 559 MBps maximum read speeds that plateau from around 256-8192 KB file chunks, and 534 MBps peak write bandwidth that plateaus from 64-8192 KB. These results agree with OCZ’s performance specifications of 550/530 MBps for the 240GB Vector 150 SSD model.

    Nice review as always Olin.
    Just one thing…
    How does it compare to a samsung SSD?
    Or did I miss that part?

    1. Olin Coles

      Unfortunately we do not have a Samsung SSD to compare against because our requests have not been answered. However, for comparison purposes, the Samsung 840 Pro uses 21nm NAND whereas Vector 150 uses 19nm NAND flash. Vector 150 reads at 550 MB/s and writes at 530 while Samsung 840 Pro reads at 540 and writes at 520 MB/s. Both read at 100K IOPS and offer a five-year warranty, but Vector 150 features 50 GB/day endurance compared to 40 GB/day for Samsung 840 Pro. I hope this helps!

    Thank you.

    I guess Samsung don’t need the reviews at this point in time.

    These are awfully close spec wise. Now to wait it out for reliability info.
