This article covers トランセンドジャパン Transcend 3D TLC NAND採用 SSD 120GB M.2 2242 SATA-III 6Gb.

Overview

Transcend's TS120GMTS420S is a 120GB SATA SSD in the M.2 2242 form factor. It features 3D TLC NAND flash memory, delivering sequential read speeds of 500MB/s and write speeds of 350MB/s. Its compact size makes it ideal for space-constrained laptops and embedded systems, offering a reliable storage upgrade at an entry-level price point. Positioned as a budget-friendly option, this drive suits users who need a small-capacity OS drive or secondary storage without breaking the bank.

Compatibility Guide

This SSD uses the M.2 2242 form factor (42mm length) and requires a SATA III (6Gb/s) interface. It is not compatible with PCIe NVMe M.2 slots that only support NVMe signaling. Check your motherboard or laptop manual to confirm that the M.2 slot supports SATA mode. The key is B-key (SATA), but most M.2 slots accept both B and M keys physically. Installation is straightforward: simply insert the drive into the slot and secure it with a screw (if included). No cables are needed.

Product Info

The Transcend TS120GMTS420S was released around 2020 and is classified as an entry-level SATA SSD. With 120GB capacity, it uses 3D TLC NAND for improved reliability over older planar NAND. It carries a 3-year warranty and supports Transcend's SSD Scope management software. Market positioning is firmly in the budget segment, emphasizing affordability and decent performance for basic use cases like boot drives in older systems or secondary storage.

Best Use Cases

Upgrade for compact laptops: Ideal for replacing HDDs or slow eMMC storage in older ultraportables such as ThinkPad X-series or similar. The SATA interface and M.2 2242 size match the specifications of many 2015-2019 laptops, drastically improving boot times and application loading. Budget OS drive: With 120GB, you can install Windows or Linux comfortably. If you have another drive for bulk data, this SSD makes an excellent dedicated boot drive for a tight budget. * Embedded or industrial systems: The Transcend SSD is known for reliability and suitability in embedded PCs or single-board computers that require a small SATA M.2 module.

Things to Consider

The limited 120GB capacity may not accommodate modern games or large applications; it's best used as a dedicated OS drive. Compared to NVMe SSDs, the SATA III interface caps speed at around 550MB/s, so this drive is significantly slower than any modern NVMe model. For desktop PCs without an M.2 2242 slot, an adapter may be needed, but physical clearance can be an issue. The 3-year warranty has a caveat: the SSD Scope health indicator showing 0% voids warranty coverage. Keep an eye on drive health if you plan long-term use. Also, due to its age, newer SSDs in the same price range may offer larger capacities or better performance.
