Transcend MTS425 M.2 2242 SATA III SSD 250GB

Bottom line: The Transcend MTS425 M.2 2242 SATA III SSD 250GB ($55.99 on Amazon as of 2026-10-06): 2242 short form factor fits slots where 2280 drives physically will not; main trade-off: SATA III caps it near 500MB/s, far below NVMe drives in the same M.2 slot.

Pros & Cons

Pros

  • ✓ 2242 short form factor fits slots where 2280 drives physically will not
  • ✓ SLC cache absorbs write bursts, cutting app and boot load times
  • ✓ LDPC error correction plus RAID engine guard against transfer-level data corruption
  • ✓ DevSleep powers down the SATA interface when idle, extending laptop runtime

Cons

  • ✗ SATA III caps it near 500MB/s, far below NVMe drives in the same M.2 slot
  • ✗ 250GB fills fast if you install more than an OS and a few applications
  • ✗ B+M key is SATA-only, so it will not work in NVMe-exclusive M.2 sockets
  • ✗ SSD Scope health software is Windows-centric, limiting Linux and Mac users

Manufacturer description

The Transcend MTS425 is a 250GB M.2 2242 SATA III SSD built for the short-slot machines that full-length 2280 drives will not fit, including ultrabooks, thin laptops, mini PCs, and desktops with a compact M.2 socket. Sequential reads reach up to 500MB/s, and built-in SLC caching absorbs bursts of writes so boot times, application loads, and general system responsiveness improve over a mechanical hard drive. The 3D TLC NAND is backed by LDPC error correction and a RAID engine that detect and correct transfer errors before they turn into data corruption, which matters on a drive you plan to…

SpecPicks Verdict

SpecPicks scored Transcend MTS425 M.2 2242 SATA III SSD 250GB using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Transcend'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 fit my laptop's M.2 slot?

It is an M.2 2242 drive (42mm long) with a B+M key edge, so it fits short 2242 SATA slots. Check your laptop manual for slot length and whether the socket is SATA or NVMe-only before ordering.

How fast is the Transcend MTS425 250GB?

Transcend rates it at up to 500MB/s, which is the practical ceiling of the SATA III interface. SLC caching helps sustain speed during write bursts.

Is 250GB enough capacity?

250GB comfortably holds Windows plus office and browsing software, but it fills quickly with large games, video projects, or big photo libraries. Treat it as a boot or lightweight-system drive.

What warranty does Transcend include?

The MTS425 carries a three-year limited warranty. Registration and claim details are handled through Transcend, so check the product listing for current terms in your region.

Does it come with cloning or monitoring software?

Yes. Transcend SSD Scope is included free and reports drive health, runs diagnostics, and helps optimize performance so you can monitor the SSD without buying separate utilities.
