Toshiba OCZ RD400 PCIe NVMe Solid State Drive Overview
Like many of the new NVMe drives the OCZ RD400 comes in the form of an M.2 drive in a PCI-Express adapter. The reason for this is many people do not have the newer motherboards that have M.2 slots with NVMe support. If you happen to have a motherboard that does have a 32 Gb/s M.2 slot then no need to buy theis version of this drive with the adapter, Toshiba does offer just the plain M.2 versions of the drive.
The drive does come with a full-height PCI bracket installed, but remember you do have the half-height bracket if you have a low-profile case. Unlike the Intel 750 there really is no cooling (heatsinks) on either side of this drive.
At the center of the PCI-Express adapter is the M.2 slot with the actual OCZ RD400 drive installed. For those wondering the OCZ RD400 is an 80 mm long M.2 drive, which seems to be the standard for most M.2 solid state drives these days.
Just like on a motherboard all you have to do is remove a single screw to take the M.2 drive out. You will not void your warranty if you remove the drive! There is some thermal tape on the backside of the drive. This should help out with cooling a little bit.
Taking the sticker off the drive a getting a closer look at it we can see what powers the RD400. The controller is Toshiba’s proprietary NVMe controller, which has a part number of TC58NCP070GSB. Our 512GB version of the drive has two 128G-bit Toshiba 15 nm MLC NAND chips. The final chip is a DRAM cache chip which is a Samsung LPDDR3 DRAM chip.
