Buy the WD_Black SN7100 2TB.

It does everything a normal PC actually needs for $100 less, without the Samsung's reported reliability drama.

What was compared

Samsung SSD 990 PRO 2TB, PCIe 4.0 M.2 2280, Up to 7,450 MB/s | NVMe Internal Solid State H... — $389.99
WD_Black SN7100 2TB NVMe SSD - Gen4 PCIe, M.2 2280, Up to 7,250 MB/s Read Speed, Up to 6,9... — $289.99

1. Same real drive experience, $100 cheaper
289.99 vs 389.99 for a drive that reads only 200 MB/s slower than the 990 Pro. Unless you're a video editor pushing sustained transfers all day, you will never feel that gap.
2. Owners report the 990 Pro failing, not this one
Multiple 990 Pro owners describe rapid health degradation, random drop-offs and system lockups months into use. That pattern doesn't show up in SN7100 owner feedback.
3. That DRAM cache only matters in workstations
The 990 Pro's onboard DRAM pays off under sustained, queue-deep write loads like professional video work. For gaming, booting Windows and normal multitasking, the DRAM-less SN7100 never hits that ceiling.
4. Built to work outside a desktop tower too
WD designed the SN7100 for laptops and handheld gaming devices, meaning tighter power efficiency and less heat to manage. The 990 Pro is a desktop-only specialist by comparison.
5. Yes, the 990 Pro is faster on paper. Skip it.
The Samsung wins on peak sequential and sustained write numbers, no argument there. But that edge only shows up in workstation-grade workloads, while its reliability complaints are the kind of risk you don't want in a boot drive.
