Toshiba os launching the OCZ VX500 SATA solid state drive (SSD) series, a mid-range SSD designed to replace the aging OCZ Vector 180. The OCZ VX500 abandons the Barefoot 3 controller and uses instead a Toshiba controller. Toshiba's TC358790 controller has been used in several products, including the Q Series Pro client SSDs and the HG6 enterprise/OEM SSD.
The OCZ VX500 makes use of SLC write caching. SLC caching on MLC SSDs allows for the highest peak performance, but at the cost of creating more work that needs to be done later to flush the cache.
Endurance ratings for the SSD is 74 to 592 terabytes written (TBW), making it suitable for write-intensive applications.
The series delivers sequential read/write speeds of up to 550 MB/s and 515 MB/s, and random read/write performance of up to 92,000 and 65,000 4KiB input/output operations per second (IOPS).

|4KB Random Write||49k IOPS||58k IOPS||64k IOPS||65k IOPS|
|Idle Power||125 mW||260 mW|
|Max Power||3.4 W|
|DEVSLP Power||5 mW||unsupported|
|Endurance (TBW)||74 TB||148 TB||296 TB||592 TB|
The OCZ VX500 SATA SSD series is available in four different capacities ranging from 128GB to 1024GB8 and will be backed by a 5-year Advanced Warranty Program. Additionally, each VX500 SSD comes bundled with Acronis TrueImage 10 cloning software.
The initial MSRPs Toshiba has set for the VX500 position it below the Vector 180 and just below the Samsung 850 EVO.
