240 GB SATA III drive for consumer upgrades

The Silicon Power Slim S55 is a 2.5 inch internal solid-state drive with a 240 GB capacity. It uses TLC memory and a SATA III interface to deliver sequential read speeds up to 460 MBps and write speeds up to 370 MBps. The 7 mm height suits ultra-slim notebooks as well as standard desktops. A mean time between failures of 1,500,000 hours supports long-term reliability.

Thermals noise and power in normal use

With no moving parts the drive runs silently and generates minimal heat during typical workloads. Shock resistance of 1500G and vibration resistance of 20G protect data integrity in mobile environments. Low power draw helps extend battery life in laptops while keeping system temperatures stable. TRIM, garbage collection and ECC maintain consistent performance over time.

Build fit and system integration

The 2.5 inch form factor fits any standard drive bay or caddy and the SATA III connection is backward compatible with SATA II 3Gbps ports. At 7 mm thick it leaves room for thermal pads or brackets in tight chassis designs. Wear levelling and bad block management extend the usable lifespan of the TLC memory. S.M.A.R.T. monitoring gives the operating system early warning of health changes.

Questions about this item

Will this 2.5-inch 7mm drive fit my ultrabook?

The drive is 7mm tall, 69.85mm wide and 100mm deep, matching the standard 2.5-inch slim bay used in most ultrabooks.

Does it work with an older laptop that only has SATA II?

Yes, the SATA III interface is backwards compatible with SATA II, so it will run at the slower 3Gbps link speed.

What software features help keep data safe over time?

The controller supports TRIM, garbage collection, wear levelling, bad-block management, S.M.A.R.T. monitoring and ECC error correction.
