A Closer Look
Silicon Power’s UD70 comes in a small black box similar to some of their other models. Basic specs can be found on the back in several languages. A clear window in the front lets you see the drive
The UD70 is your standard 2280 sized M.2 M-Key drive. It comes with a blue PCB with a sticker covering most of the front.
The back is not black, it’s the same dark blue as the front, but for some reason, we had a hard time getting a good picture of it. There is little to see on the back, the 2TB model doesn’t come populated, but there are contact pads for four more DRAM modules as well as a NAND flash module.
On the front, four QLC 3D NAND flash modules make up the 2TB of capacity. We weren’t able to find a spec sheet for these specific modules.
Closer to the connector we find a Phison E12 controller which is a recent high-performance 8-channel controller that Phison says is capable of up to 600k IOPS.
Cache is handled with a Kingston 512MB DDR3L module running 1866 Mbps.
