Toshiba OCZ VX500 512GB Review

Rating: 8.0.

Toshiba OCZ already has the RD400 in the high-end/enthusiast SSD market segment and the TR150 at the value end of it. Notably missing was a new up to date drive to compete in the mainstream market. That gap has now been filled with the launch of the VX500 series.  It will take over from the old VT180 (Vector 180) mainstream series as that product line becomes end of life.



The VX500 range is made up of 128GB, 256GB, 512GB and 1TB capacities. Under the skin, the controller and the 15nm 512Gbit MLC NAND are all Toshiba in-house designs. Incidentally, while the 512GB drive and lower capacities do not have any separate cache memory chip(s), the 1TB drive does make use of a single cache chip.

Toshiba OCZ quotes sequential performance figure for the 512GB drive at up to 550MB/s for reads and up to 515MB/s for writes. Random 4K performance is listed as up to 92,000 IOPS for reads with writes up to 65,000 IOPS.

Endurance for the 512GB drive is quoted at 296TB TBW, which works out to be around 162GB a day as the whole VX500 range is backed by a 5yr warranty.

Physical Specifications:

  • Usable Capacities: 128GB, 256GB, 512GB, 1TB

    Great review thanks!

    Seems like a decent drive, does make me wonder if they are going to continue the old Vector (VT) line and try and claw back some of the high end consumer market segment.

    This seems like a very safe, solid drive and that should’t be an issue. But for better or worse OCZ was always a fairly avant guarde, forward looking company. This drive feels like a tweaked rebaged of the Q300, is this what OCZ has become?

    What happened to Barefoot 3 and Indilinx controllers, sure they lacked low power sates, but it rivalled the might of Samsung for years! I was really hoping to see an evolution of this tech. Hell maybe it (The IP) has been incorporated into the new Toshiba Controllers and we would never know. But the new Tosh drives seem to behave so different in the benchmarks I doubt it.

    I guess I was just hoping for something a little different from OCZ, in a very very similar and saturated SSD Market. For better or worse they always had an interesting product line up…
