Transcend MTS425S 1 TB (TS1TMTS425S)

The Transcend MTS425S is a line of compact internal SATA SSDs in the M.2 2242 form factor designed for ultrabooks, thin laptops, mini PCs, and embedded systems where standard 2.5-inch drives or longer M.2 2280 modules don't fit. The series uses the SATA III 6 Gbps interface with 3D NAND and is available in capacities of 250 GB, 500 GB, 1 TB, and 2 TB. All models share identical dimensions of 42.0 × 22.0 × 3.58 mm and weigh around 5 grams, making them ideal for thin devices with short M.2 2242 slots. Read and write speeds vary by capacity: the 250 GB model delivers up to 500/330 MB/s, the 500 GB reaches up to 530/480 MB/s, while the 1 TB and 2 TB models achieve up to 550/500 MB/s respectively. 4K random access performance also scales with capacity, reaching 40,000/75,000 IOPS on the 250 GB, 50,000/75,000 IOPS on the 500 GB, 55,000/72,000 IOPS on the 1 TB, and 55,000/80,000 IOPS on the 2 TB model. The series includes SLC caching, LDPC ECC, Garbage Collection, DevSleep, and S.M.A.R.T. monitoring, with write endurance ranging from 90 TBW on the 250 GB to 720 TBW on the 2 TB. The Transcend MTS425S is perfectly suited for upgrading compact laptops or mini systems when you need a SATA SSD in the short M.2 2242 format without sacrificing speed compared to traditional 2.5-inch models.
