This article covers Transcend 3D TLC NAND採用 SSD 240GB M.2 2280 SATA III 6Gb.

Overview

The Transcend TS240GMTS820S is an M.2 2280 SATA III 6Gb/s internal SSD with a 240GB capacity, built with 3D TLC NAND flash memory. It delivers sequential read and write speeds of up to 480MB/s, making it a solid choice for budget-conscious users looking to upgrade from a traditional hard drive. This drive is positioned as an entry-level storage solution, ideal for small-form-factor PCs and laptops where space is at a premium. Transcend backs this SSD with a 3-year warranty, and the included SSD Scope software allows you to monitor drive health and estimate remaining lifespan. Note that the warranty does not apply if the SSD Scope health indicator reaches 0%.

Compatibility Guide

This SSD uses the M.2 2280 form factor and requires a SATA III 6Gb/s interface. It is crucial that your motherboard or laptop has an M.2 slot that supports SATA mode, as NVMe-only slots will not recognize this drive. Some motherboards offer dual-mode M.2 slots that can be switched between SATA and PCIe in the BIOS. Form factor: M.2 2280 Interface: SATA III 6Gb/s (requires SATA 6Gbps port) Compatible with: Desktops and laptops with an M.2 SATA slot Caution: Not compatible with NVMe-only M.2 slots

Product Info

The Transcend TS240GMTS820S was released around 2018 and sits in the entry-level price tier. Its market position is as a cost-effective upgrade for boot drives and basic application storage, rather than for high-speed data transfers or large media libraries. Capacity: 240GB Interface: SATA III 6Gb/s Form factor: M.2 2280 NAND flash: 3D TLC Sequential read: up to 480MB/s Sequential write: up to 480MB/s Warranty: 3 years (excludes drives with 0% SSD Scope health indicator) Software: Transcend SSD Scope (health monitoring and lifespan estimation)

Best Use Cases

Budget PC builders: If you are building a low-cost system and want a noticeable speed boost over an HDD, this SSD is a great fit. The 240GB capacity is enough for the operating system and a few essential applications, dramatically improving boot times and program loading. Upgrading compact PCs and laptops: For thin notebooks or Mini-ITX builds where a 2.5-inch drive won't fit, this M.2 SATA SSD is a perfect space-saving solution. Its low power consumption and minimal heat output make it suitable for thermally constrained environments. * Secondary storage: If your primary drive is a fast NVMe SSD, adding this SATA SSD as a secondary drive for documents, downloads, or game libraries is a practical way to expand capacity without occupying an NVMe slot or consuming PCIe lanes.

Things to Consider

The most significant limitation is the SATA III interface, which caps performance at around 480MB/s. This is far slower than even entry-level NVMe SSDs, so this drive is not suitable for tasks that demand high sequential throughput, such as 4K video editing or loading large game worlds. With only 240GB of storage, you will quickly run out of space if you install multiple modern games or store large media collections. For a similar price, you might find a 480GB SATA SSD or a budget NVMe drive that offers better value per gigabyte. Always verify that your system has an M.2 slot that supports SATA mode. Many newer motherboards have NVMe-only M.2 slots, and using this drive in such a slot will result in it not being detected. Check your motherboard manual or specifications before purchasing. ## Alternatives
Direct competitors in the same price bracket include the Crucial BX500 and Kingston A400 series, both of which are 2.5-inch SATA SSDs. They offer similar performance and pricing, but their larger form factor makes them unsuitable for systems that only have M.2 slots. The Transcend TS240GMTS820S wins on space efficiency. If your system supports NVMe, consider the WD Blue SN580 or similar budget NVMe drives. They cost a bit more but deliver dramatically faster speeds (up to 4,000MB/s), making them a better long-term investment for most users. However, if you are limited to SATA M.2 slots, the Transcend is a reliable and affordable choice.
