The Transcend 425S is a compact M.2 SATA III 6Gb/s solid state drive designed to bring faster performance to slim devices. Utilizing high-quality 3D NAND flash, this 250GB model provides a significant speed boost over traditional hard drives for quicker system boot times. You can expect sequential read speeds up to 530MB/s and write speeds up to 480MB/s, while 4K random performance reaches up to 75,000 IOPS to ensure a snappy response when running multimedia applications. Measuring just 42mm in length and weighing only 5g, this drive is specifically tailored for Ultrabooks and lightweight notebooks where internal space is limited. It operates on a DC +3.3V voltage and includes DevSleep technology, which intelligently shuts down the SATA interface during inactivity to help extend your laptop's battery life. To maintain long-term health, the drive employs wear-leveling and garbage collection to distribute data evenly and prolong the lifespan of the memory cells. This 250GB SSD is an ideal choice for users looking to upgrade a small-form-factor laptop without sacrificing reliability. It comes with LDPC coding to prevent data corruption and is compatible with Transcend SSD Scope software, allowing you to monitor the drive's condition and optimize its performance directly from your operating system.
