With the Radeon R7, AMD has made its long awaited entrance into the consumer solid state drive market. The result of a partnership between AMD and OCZ, this good looking, ultra-slim drive combines the Indilinx-infused Barefoot 3 M00 controller with Toshiba´s latest A19nm MLC NAND flash to deliver a good mix of performance, endurance and value. In our sequential read and write tests, the 240GB version of the Radeon R7 was able to read at speeds as high as 549 MB/s and write at speeds in excess of 425 MB/s. It also did reasonably well in our random write tests, producing more than 59,000 IOPS at low queue depths. As you´d expect, the Radeon R7 performed better at higher queue depths. However, it still had a hard time keeping up with some of the higher priced, enthusiast-oriented SSDs like OCZ´s own Vector 150 and Samsung´s 850 PRO. Despite its many strengths, OCZ´s Barefoot 3 controller has been around for a few years now and is starting to get a bit long in the tooth. Where the latest controllers from Marvell and Samsung offer support for Device Sleep (DEVSLP) mode and self-encrypting drive (SED) technologies that are TCG Opal 2.0 and eDrive compliant, the Barefoot 3 does not. Given, this probably isn´t an issue if you´re looking for an SSD for your gaming rig. However, these are things you may want to consider if the Radeon R7 is going in a laptop or you´re in a situation where data security is a concern. The Radeon R7 is available now in 120GB, 240GB and 480GB capacities. Prices on Amazon currently range from $85 up to $244, with the 240GB version reviewed here going for about $130.
