Pros & Cons

Pros

✓ Up to 545 MB/s sequential reads -- saturates the SATA III 6 Gb/s ceiling
✓ SLC caching absorbs burst writes during app launches and file copies
✓ Ultra-low power draw extends laptop battery life on sustained reads

Cons

✗ SATA III caps it at 545 MB/s -- NVMe M.2 drives run several times faster

✗ 480GB fills fast if you install modern games alongside the OS
✗ No published TBW endurance or DRAM cache spec in the listing details

Manufacturer description

The WD Green 480GB SSD (WDS480G3G0B) is Western Digital's entry-level SATA drive, built for people upgrading a laptop or filling out a desktop's storage without touching the boot budget. It ships in the M.2 2280 form factor on a SATA III 6 Gb/s interface, with sequential reads rated up to 545 MB/s -- roughly the practical ceiling for SATA, and about five times what a spinning 7200 RPM drive delivers on the same connection. SLC caching absorbs bursts of small writes, so routine work like booting, launching apps, and moving project folders finishes quickly rather than queuing behind the drive…

SpecPicks Verdict

SpecPicks scored Western Digital 480GB WD Green 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. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Will this M.2 drive work in any M.2 slot on my motherboard?

Only in a slot that supports SATA-mode M.2. This is a SATA III 6 Gb/s drive in an M.2 2280 shell, not an NVMe drive. Many boards have PCIe-only M.2 slots, so check your motherboard manual for SATA M.2 support before buying.

How fast is the WD Green 480GB compared to a hard drive?

Western Digital rates it at up to 545 MB/s sequential reads, which is the practical maximum for the SATA III 6 Gb/s interface. That is roughly five times the throughput of a typical 7200 RPM mechanical hard drive on the same connection.

Is 480GB enough capacity for a gaming PC?

It is enough for Windows plus a handful of titles, but modern games routinely run 50-100GB each, so a 480GB drive fills quickly. It works better as a boot and application drive, or as a secondary drive in a laptop with limited bays.

What warranty comes with this drive?

Western Digital covers the WD Green SATA SSD with a 3-year limited warranty. Registering the drive in the free Western Digital SSD Dashboard also lets you monitor health status and firmware over the life of the drive.

Does it drain laptop battery the way a hard drive does?

No. Western Digital specifies ultra-low power draw for the WD Green line specifically so laptops run longer between charges. It also has no moving parts and is shock-resistant, which helps in a machine that gets carried around.
