Pros & Cons
Pros
- ✓ 2TB capacity in the mainstream SATA tier, room for large game libraries
- ✓ Up to 560 MB/s read essentially saturates the SATA III 6 Gb/s bus
- ✓ 7mm z-height fits ultrabooks and slim laptop bays that reject 9.5mm drives
- ✓ 2.5-inch SATA works in older desktops and laptops with no M.2 slot
Cons
- ✗ 560 MB/s read is a fraction of what an NVMe Gen4 drive delivers
- ✗ SATA III interface is a hard ceiling - no headroom as systems get faster
- ✗ Write speed (520 MB/s) trails read speed on sustained transfers
- ✗ Needs a 2.5-inch bay plus SATA data and power cables, unlike M.2 drives
Manufacturer description
The WD Blue SA510 2TB brings mainstream SATA storage to any desktop or laptop with a free 2.5-inch bay. Western Digital rates this drive at up to 560 MB/s sequential read and up to 520 MB/s sequential write over a SATA III 6 Gb/s interface, which is effectively the ceiling of what SATA allows -- so the SA510 is about saturating the bus you already have rather than chasing NVMe numbers. The 7mm z-height matters more than the spec sheet suggests: it clears the drive bays in most ultrabooks, older gaming laptops, and small-form-factor cases where a thicker 9.5mm drive will not seat. At 2TB…
SpecPicks Verdict
SpecPicks scored Western Digital 2TB WD Blue SA510 SATA Internal Solid State Drive SSD using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Western Digital's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for ssds & storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
How fast is the WD Blue SA510 2TB?
Western Digital rates it at up to 560 MB/s sequential read and up to 520 MB/s sequential write over SATA III 6 Gb/s. That is at the practical limit of the SATA interface -- an NVMe drive would be several times faster, but only if your system has a free M.2 slot.
Will this fit in my laptop?
It is a 2.5-inch drive at 7mm thickness, which is the slim standard that fits most laptop drive bays, including ultrabooks that reject 9.5mm drives. Confirm your laptop has a 2.5-inch SATA bay rather than only an M.2 slot before ordering.
Is 2TB enough for a game library?
2TB holds roughly 15-25 modern AAA titles at current install sizes, or far more indie and older games. Many builders pair it with a smaller NVMe boot drive and use the SA510 as the bulk library drive.
What warranty does the WD Blue SA510 come with?
Western Digital publishes warranty terms by capacity and region for the WD Blue SA510 line. Check the current product listing and Western Digital's support page for the terms that apply to the 2TB WDS200T3B0A model you are buying.
