Transcend SSD370 (Premium) 256GB SATA 6Gb/s Internal Solid State Drive

Model: TS256GSSD370 | Series: SSD370 | 256GB Capacity | 2.5" Form Factor

The Transcend SSD370 (often referred to in its aluminum chassis version as the SSD370S) was a standout "performance-value" drive during the transition to 3D NAND. Known for its inclusion of MLC (Multi-Level Cell) NAND, it offers significantly higher write endurance and better long-term reliability than the cheaper TLC or QLC drives common in today's budget market.

• Capacity: 💾 256 GB

• Interface: ⚡ SATA 6Gb/s (SATA III)

• NAND Type: 🧠 MLC NAND Flash (High Endurance)

• Controller: 🧠 Transcend TS6500 (Silicon Motion SM2246EN base)

• Sequential Read: 🏎️ Up to 560 MB/s

• Sequential Write: ✍️ Up to 310 MB/s

• Random Read/Write: 📉 70,000 / 70,000 IOPS

• Endurance (TBW): 🛡️ 280 TBW (Total Bytes Written)

• MTBF: 🕒 1.5 Million Hours

• MLC Advantage: Most consumer drives today use TLC or QLC memory, which can wear out faster. The SSD370 uses MLC NAND, which stores fewer bits per cell. This results in superior data retention and a much higher endurance rating—making it an excellent choice for a drive that will see a lot of writing.

• DevSleep Support: This drive supports SATA Device Sleep Mode (DevSleep). Unlike traditional standby modes, DevSleep completely shuts down the SATA interface when not in use, which can significantly extend the battery life of a laptop while still allowing the drive to wake up in under 100 milliseconds.

• Aggressive Garbage Collection: The firmware includes advanced garbage collection and wear-leveling algorithms. These ensure that the drive maintains its speed over time by proactively cleaning up "stale" data blocks, preventing the slow-down common in older SSDs as they fill up.

• SSD Scope Software: Transcend provides a dedicated software suite that allows users to monitor S.M.A.R.T. health status, enable TRIM, update firmware, and even clone their existing hard drive to the new SSD with a single click.

• Target Systems:

  • Desktop Upgrades: Often included a 3.5-inch bracket in the box, making it easy to install in older PC cases that lack dedicated 2.5" SSD mounts.

  • Laptops & Ultrabooks: Its 7mm slim profile fits in modern thin-and-light notebooks as well as older mainstream laptops.

  • Legacy PCs: Fully backward compatible with SATA II (3Gb/s) and SATA I (1.5Gb/s) systems.

• Ideal Workloads:

  • Home Office: Reliable, snappy performance for multitasking and general Installation Note

    💡 Pro Tip: The TS256GSSD370 is the version housed in a durable plastic case, while the "S" suffix version (TS256GSSD370S) features an aluminum housing. Internally, they are nearly identical, but the aluminum version offers slightly better heat dissipation for sustained workloads.

    The Transcend SSD370 is a "Universal Soldier" of storage. Its MLC flash makes it much more durable than modern budget drives, making it a reliable pick for both legacy system revivals and active professional use.
