OCZ Vector 150 SSD Review

AS-SSD Benchmark

Alex Schepeljanski of Alex Intelligent Software develops the free AS SSD Benchmark utility for testing storage devices. The AS SSD Benchmark tests sequential read and write speeds, input/output operational performance, and response times.

AS-SSD Benchmark uses compressed data, so sequential file transfer speeds are reported lower than with other tools using uncompressed data. For this reason, we will concentrate on the operational IOPS performance in this section.

Beginning with sequential transfer performance, the 240GB OCZ Vector 150 solid state drive produced speeds up to 507.18 MB/s for reads and 494.43 MB/s writes. Single-threaded 4K IOPS performance tests deliver 22.25 MB/s read and 66.27 MB/s write, while the 64-thread 4K reads recorded 338.75 MB/s and write performance was at 304.05 MB/s.

AS-SSD 64-thread 4KB IOPS performance results are displayed in the chart below, which compares several enthusiast-level storage products currently on the market. In the 64-thread 4KB IOPS performance tests, the 240GB OCZ Vector 150 SSD easily surpassed much of the competition, and nearly matched performance with the original Vertex 4 solid state drive.

The chart below is sorted by total combined performance, which helps illustrate which products offer the best operational input/output under load:

    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.
