Transcend TS480GMTS420S – 420S 480 GB Solid State Drive – M.2 2242 SATA SSD

Transcend’s ultra-compact 420S M.2 SATA III 6Gb/s SSD meets the high-performance demands and strict size constraints of small form factor devices. It fits perfectly in Ultrabooks and thin, lightweight notebooks. Moreover, it combines high-quality 3D NAND flash with enhanced firmware algorithms to deliver outstanding reliability and speed.

Unlike traditional planar NAND chips, 3D NAND flash stacks memory cells vertically in multiple layers. As a result, this advanced structure boosts performance and endurance by overcoming the density limitations of 2D NAND technology.

In addition, Transcend’s M.2 SSDs—including the 420S—comply with both Type 2242 and 2280 M.2 form factors. Therefore, they are ideal for modern Ultrabooks and compact notebooks. Measuring just 42mm in length, the 420S enables quick and space-saving upgrades while significantly boosting system energy efficiency.

Thanks to the SATA III 6Gb/s interface and a powerful controller, the 420S achieves impressive read and write speeds of up to 530MB/s and 480MB/s. When used as a cache drive, it reduces boot time by up to 1.5 times compared to conventional hard drives.

Furthermore, the drive supports up to 75,000 IOPS for 4K random read/write, which dramatically reduces loading times. Consequently, users experience smooth performance during graphics-intensive and multimedia applications.

The M.2 form factor not only saves space but also supports greater storage capacities compared to mSATA and half-slim drives. Despite its compact design, the 420S includes advanced technologies such as a RAID engine, built-in SLC caching, and LDPC (Low-Density Parity Check) coding. These features work together to maintain data integrity and deliver faster access times.

Additionally, wear-leveling technology distributes data evenly across memory cells, which extends the SSD’s lifespan. The built-in SLC caching stores frequently accessed data, further enhancing speed and responsiveness.

Transcend also provides SSD Scope software, which allows users to monitor drive health, optimize performance, and update firmware effortlessly. As a result, users can maintain their SSD’s top performance over time. The drive also includes power-loss protection to help prevent data loss during unexpected shutdowns. Moreover, its low power consumption makes it ideal for extending battery life in notebooks.

In conclusion, Transcend rigorously tests every SSD to ensure high-quality standards. Therefore, the 420S stands out as a reliable, durable, and high-performing upgrade for any compact computing system.
