Ranked by what users actually praise

Overall Impression

Blazing speed and strong sale pricing make this a favorite pickup for gamers and PC builders. Multiple commenters report near-advertised 7000+ MB/s speeds, describing it as among the fastest NVMe drives they've used, with some calling it 'the best purchase of my life.' Buyers frequently mention snagging 1TB, 2TB, and 4TB units on Black Friday, Cyber Monday, or Prime Day deals at prices well below MSRP, often citing it as a great bang for the buck compared to Samsung or Seagate alternatives for PS5 or PC builds.

Reliability is inconsistent, with some drives dying suddenly or failing to be detected. Several users report the drive suddenly disappearing from BIOS or Disk Management after weeks or months of use, sometimes with large amounts of data lost, particularly in 8TB units and external enclosures. Others describe games crashing repeatedly until switching back to a Samsung drive, or one of two purchased 8TB drives freezing the system entirely, suggesting possible unit-to-unit quality variance or heat-related failure.

Heat management and companion software are recurring pain points. Some buyers report the controller running notably hot during heavy use or in third-party enclosures without proper thermal pads, occasionally linked to failures. Others found it stayed cool without a heatsink under lighter use. Meanwhile, WD's Dashboard app is repeatedly criticized for spiking CPU usage dramatically, with WD's own support reportedly confirming the issue without a fix, souring an otherwise strong drive.
