What reviewers say

WD Blue SA510 SSD

  • 4.6 / 52,700 ratings

Owners rate it highly, mostly as a cheap way to make an old laptop or desktop feel new. Complaints center on sustained write speed and on the SATA ceiling rather than reliability.

What people mention
  • SpeedPraisedOwners say boot times and app launches improve sharply over a hard drive.
  • Sustained writesCriticisedLarge file copies slow down once the cache is exhausted.

  • NoisePraisedUsers note the drive is silent and free of hard-drive vibration.

Questions and answers

Which is faster?
The Seagate Nytro 5350M. Its 7,400 MB/s read is far above the WD Blue SA510's 560 MB/s, but you only see that speed on a PCIe 4.0 NVMe connection.
Will the WD Blue SA510 fit my laptop?
Only if the laptop has a 2.5-inch SATA bay. Many modern laptops use M.2 NVMe slots instead, and this drive will not fit those.
Can I use the Seagate Nytro in a normal desktop?
Only with a PCIe 4.0 x4 NVMe slot or an adapter that accepts a 2.5-inch NVMe drive. A plain SATA port will not work.
Which holds more data?
The Seagate Nytro 5350M at 3.84TB, against 2TB for the WD Blue SA510.
Which lasts longer?
The WD Blue SA510 is rated at 500 TBW. Seagate gives no endurance figure for the Nytro 5350M here, so the WD is the only one with a stated rating.
Is the Seagate worth the extra money?
No new price was given for the Nytro 5350M, so the gap cannot be stated. The WD Blue SA510 is $507.39 at Staples as of November 7, 2026.
