Transcend MTS430 512GB M.2 2242 SATAIII SSD with Dram Cache

Bottom line: The Transcend MTS430 512GB M.2 2242 SATAIII SSD with Dram Cache: DRAM cache (DDR3) keeps access times low, unlike DRAM-less 2242 rivals; main trade-off: SATA III caps it at 560MB/s — NVMe drives run several times faster.

Pros & Cons

Pros

  • ✓ DRAM cache (DDR3) keeps access times low, unlike DRAM-less 2242 rivals
  • ✓ M.2 2242 length fits short slots that reject 2280 drives
  • ✓ Hits SATA III ceiling: up to 560MB/s read, 500MB/s write
  • ✓ 5-year warranty from Transcend
  • ✓ LDPC error correction plus a RAID engine guard against transfer errors

Cons

  • ✗ SATA III caps it at 560MB/s — NVMe drives run several times faster
  • ✗ B+M key and 2242 length must both match your slot
  • ✗ 512GB fills fast if you store games or video projects
  • ✗ TLC NAND slows once the SLC cache is exhausted on long writes

Manufacturer description

The Transcend MTS430 512GB is an M.2 2242 SATA III SSD built for the short-slot bays that full-length 2280 drives can't fill — ultrabooks, thin notebooks, mini PCs, and older laptops with a B+M key socket. Transcend rates it at up to 560MB/s sequential read and 500MB/s write over the SATA III 6Gb/s interface, which is the practical ceiling for the SATA bus, so you get the full jump from a mechanical drive without needing an NVMe slot. What separates it from budget 2242 drives is the DDR3 DRAM cache: a dedicated buffer for frequently accessed data that keeps access times short under sustained…

SpecPicks Verdict

SpecPicks scored Transcend MTS430 512GB M.2 2242 SATAIII SSD with Dram Cache 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.

Frequently Asked Questions

Will this fit my laptop's M.2 slot?

It is an M.2 2242 module (42mm long) with a B+M key connector. Check that your machine's slot accepts a 2242-length SATA drive — a 2280-only slot will not hold it, and an NVMe-only slot will not detect it.

How fast is the Transcend MTS430 512GB?

Transcend rates it at up to 560MB/s sequential read and 500MB/s sequential write over the SATA III 6Gb/s interface. That is at the top of what SATA allows, though NVMe drives are considerably faster.

Does it have a DRAM cache?

Yes. It uses a DDR3 DRAM cache that holds a temporary copy of frequently accessed data to shorten access times. It also uses an SLC cache layer in front of the 3D TLC NAND for write bursts.

What warranty does Transcend include?

Transcend lists a 5-year warranty on this drive. Check the product listing for current registration requirements and regional terms before you buy.

Is it reliable enough for a daily-driver laptop?

It includes a RAID engine plus LDPC (Low-Density Parity Check) error correction to detect and correct data transfer errors.

Key Features

  • M.2 2242 Form Factor: The MTS430S has a small, space-saving design, making it suitable for ultrabooks, thin laptops, and other devices with limited internal space.
  • SATA III 6Gb/s Interface: It uses the SATA III interface, offering fast sequential read and write speeds of up to 560MB/s and 500MB/s, respectively.
  • DRAM Cache: It includes a DRAM cache that stores a temporary copy of the most frequently accessed data, which helps to significantly shorten access times and improve overall performance.
  • Data Integrity Technologies: The SSD incorporates several advanced features to ensure data reliability and longevity. These include a RAID engine and LDPC (Low-Density Parity Check) coding to detect and correct data transfer errors.
  • 5 Year Warranty
