Model: Toshiba OCZ RD400 512GB PCIe NVMe M.2 Solid State Drive

Toshiba has been a leader in the consumer electronics industry for as long as I can remember. Founded more than 70 years ago, this Japanese company manufacturers everything from tiny electronic components to consumer products like televisions, Blu-ray players and personal computers. Toshiba is no stranger to the storage industry either. The company designs and manufactures high-quality flash memory-based storage solutions, SSDs and hard disk drives for the consumer and enterprise markets.

To strengthen their position in the SSD market, Toshiba purchased the assets of OCZ Technology's SSD business in December of 2013. The business was soon re-launched as an independently-operated subsidiary named OCZ Storage Solutions. OCZ has continued to operate this way until recently, when Toshiba fully absorbed the business, turning the subsidiary into one of its sub-brands. To reduce the overlap between product lines, OCZ also pulled out of the enterprise market and will function as a consumer-only brand.

The first drive launched under Toshiba's new OCZ sub-brand is the RD400. Designed with enthusiasts and hard-core gamers in mind, the RD400 is the company's first  consumer-ready Non-Volatile Memory Express (NVMe) SSD. This NVMe 1.1 compliant, M.2 form factor drive is powered by Toshiba's TC58NCP070GSB controller and is available with up to 1TB of their 15nm MLC NAND flash. With its PCIe Gen3 x4 lane interface, the RD400 also shatters the traditional SATA bottleneck by delivering over four times the performance of SATA SSDs.

The RD400 is available in 128GB, 256GB, 512GB and 1TB capacities. For this review, OCZ sent us the 512GB version of the drive which is capable of delivering up to 2,600 MB/s sequential read and 1,600 MB/s sequential write speeds as well as up to 190,000 random read and 120,000 random write IOPS.
