Silicon Power UD90 1 TB M.2 NVMe SSD

[W1zzard]

Priced at $110, the Silicon Power UD90 is an affordable PCI-Express 4.0 M.2 NVMe SSD, offering transfer rates of up to 4.8 GB/s. Under the hood, the UD90 uses the new Phison E21 controller and Micron's 176-layer 3D TLC NAND.

Decent drive, but overpriced; SM should've rather sampled you the 2TB SKU.

Would it be possible to add a power draw test similarly to what Anandtech does? The E21 controller should be noticeably more power-sipping than its competitors, which might make this drive a good use-case for a laptop or similar portable device.

And what is with manufacturers offering such small pSLC caches FFS? Why don't they just make the cache size itself dynamically to how full the drive is, i.e. the less data the drive has on it the larger the cache is and the faster it performs with large files? This seems like an extremely simple firmware feature to implement.

You can checkout power consumption on tH: https://www.tomshardware.com/reviews/silicon-power-ud90-ssd-review/2
which pretty much confirms what you say, it's really looking good for low power applications. I hope we see more competition using this controller so that we can see its price go down. Silicon Power is supposed to be a "budget" brand, but their pricing has not kept up with the times.

While WD is still being crazy where I live with the SN850 1TB at ~ 180USD, the KC3000 is getting cheaper and cheaper everyday. The 1TB now sits at ~105USD and the 2TB sits at ~210USD. This bodes well for maybe one day the 4TB version to hit a sane price too, it currently sits at ~600USD.

I wish 4TB was mid and 8TB large and 2TB small for ssds...................., instead its like sub-1TB econo/subcompact, 1TB small, 2TB mid and 4TB very large

1TB is fine for OS/Boot drive, however for storage, steam etc. it's a bit on the small side, and prices don't scale. When four separate 1TB drives are cheaper than one 4TB drive, that's called a rip off.

Reddit user reported that 2TB version of this nvme (UD90) he received is using Micron QLC.

Hi Since Forspoken supports Direct Storage could you add that to your storage reviews in the Gaming loading section?

I just picked up the Silicon Power UD90 here in the states from NewEgg for $95usd for the 2 TB version. Plan to store all my games on this drive and will not be my boot drive. I use a Crucial P5 Plus for that; another good performance\value M.2.
