Pros & Cons

Pros

  • ✓ Up to 550 MB/s reads saturate the SATA III 6 Gb/s bus
  • ✓ SLC caching absorbs bursts of small writes during patches and updates
  • ✓ 2.5in/7mm case fits nearly any laptop bay or desktop with an adapter
  • ✓ Free WD SSD Dashboard monitors drive health and firmware

Cons

  • ✗ SATA III caps speed near 550 MB/s - NVMe drives are several times faster
  • ✗ WD Green is the entry tier; WD Blue and Black target heavier workloads
  • ✗ No DRAM cache is typical of this tier, so sustained large writes can slow
  • ✗ 2.5in form factor is dead weight in modern M.2-only laptops

How fast is the WD Green 2TB SSD?

Western Digital rates it at up to 550 MB/s over the SATA III 6 Gb/s interface, which is effectively the ceiling for any SATA drive.

Will this fit my laptop?

Does it come with software to check drive health?

Yes, the free WD SSD Dashboard lets you monitor storage status and drive health after installation.
