At the heart of all of the SSDs on the bench today is Phison's PS5007-11 or E7 quad-core, 8-channel NVMe controller.

Going from top to bottom, we have 960GB, 480GB, and 240GB M.2 SSDs.

Phison labels their M.2 drives on the motherboard side of the drives. This allows for better cooling on the controller side. The drives are labeled as non-OP, but they are actually Over-Provisioned, which is typically how they will be sold on the retail market. The 240GB and 480GB drives are single sided designs, and the 960GB drive is double sided. All of the drives we are testing today feature Toshiba 15nm planar MLC (2bit) flash.

The controller side of the 480GB AIC SSD. This drive features 2MB DRAM per GB of flash. Double the DRAM cache of the M.2 versions, which is why the AIC is a bit faster. Like the M.2 drives, the AIC is labeled as 512GB, but it is actually overprovisioned, resulting in 480GB.
