Hybrid drive for thin laptops

The Seagate ST500LX012 is a 500 GB solid-state hybrid drive built for 2.5 inch bays only 5 mm high. It combines a 5400 RPM platter with 8 GB of NAND flash cache to deliver SSD-like boot and application speeds over a SATA 6.0 Gb/s link. The all-in-one design fits ultra-thin notebooks and small-form-factor systems where a full-height drive will not fit.

Suits capacity-first upgraders

This drive targets users who need 500 GB of space in a slim chassis and want faster start-up than a standard hard disk. Buyers who require sustained write throughput for video editing or database work should consider a pure solid-state drive instead. Systems limited to SATA 3.0 Gb/s will still operate but at the slower bus rate.

Drop-in SATA installation

Installation is a straight swap: secure the 69.85 mm by 100.35 mm unit in the bay, connect the SATA data and power cables, and the drive appears as a single volume with no extra drivers. The hybrid controller manages caching automatically. A small number of units may show up to 25 bad sectors; a full surface scan before deployment is recommended.

Questions about this item

Does my laptop need a 2.5 inch bay that accepts a 5mm high drive for the ST500LX012?

Yes, the drive is a 2.5 inch form factor with a maximum height of 5mm, so the bay must accommodate that thickness.

Will the SATA 6.0Gb/s interface on this hybrid drive work with my older laptop that only supports SATA 3.0Gb/s?

The SATA 6.0Gb/s interface is backward compatible and will operate at the slower 3.0Gb/s speed on older controllers.

How can I verify the 8GB NAND flash cache is accelerating boot and load times after installing the ST500LX012?

You should notice faster boot and application launch speeds compared to a standard 5400 RPM hard drive, as the hybrid design caches frequent data in the 8GB NAND flash.
