Silicon Power 2TB NVMe M.2 PCIe Gen3x4 2280 SSD Solid State Drive (SP002TBP34A60M28) vs WD_BLACK SN850X 2TB NVMe SSD

This is the drive you buy when you want 2TB for the price of a decent dinner out. It runs on Silicon Motion's SM2263XT controller with TLC NAND, and it skips a dedicated DRAM cache in favor of Host Memory Buffer to keep the cost down.

In day-to-day use it is genuinely fine. Windows boots fast, games load fine, and large transfers are quick right up until the SLC cache fills, at which point write speed drops noticeably. That is the trade you accept at this price.

At Gen3 speeds of roughly 2,200 MB/s read, it is no match for a Gen4 drive, and it is not the one to drop in a PS5. But as a bulk storage or secondary game drive, it does exactly what it promises and nothing it does not.

The SN850X is one of the best Gen4 SSDs you can buy, and the bare version is the smart way to own it. You get the full 7,300 MB/s read and 6,600 MB/s write, a proper 2GB DDR4 DRAM cache, and a controller that holds its speed under sustained load far better than budget drives.

Where it really shines is the stuff a spec sheet hides: random performance and consistency. Game levels stream in, big project files open instantly, and it stays fast when you hammer it.

The only real watch-out is heat. Without a heatsink it can run warm under heavy sustained writes, so pair it with a motherboard M.2 heatsink. Most modern boards include one, which makes this version the better value than paying extra for WD's.
