Silicon Power has decided to opt for the minimalist approach with packaging on the UD90 – just like their other product lines. Having no-fuss packaging is a great idea since this can be easily recycled once the drive is removed. As you can see there is very little by way of information, aside from some of the basic stats surrounding the speed, capacity and warranty. To extract the drive from the packet, we just need to slice the back. The drive comes on its own with a plastic container.


UD90 conforms to the M.2 form factor and more specifically the 2280 size, it has no integrated heatsink like other M.2 SSDs you find on the market, so in this sense it will have no issues in terms of physical compatibility. The sticker that sits over the top side is nicely designed and should marry up with other hardware reasonably well.

UD90 uses the Phison E21T controller which is DRAM-less. This drive also lends itself to using 176-layer TLC Flash.

Over the next pages we’ll be putting the UD90 under examination to see what you can expect in terms of performance.
