Silicon Power Ace A55 2TB SATA SSD

The Silicon Power Ace A55 is a 2.5 inch SATA internal solid state drive built for consumers who need a straightforward capacity upgrade. It fits laptops and desktops with a standard 7mm drive bay and connects over the SATA III interface.

2TB capacity with SATA speed limits

The drive offers 2TB of usable space, enough for an operating system, applications and a large media library. Sequential reads reach up to 500 MBps and writes up to 450 MBps, so large file copies move quickly within the SATA bottleneck. Random mixed workloads and sustained heavy writes will hit the interface ceiling before the flash does.

Silent operation with low power draw

With no moving parts the SSD runs completely silent in normal use. Power consumption stays low, helping notebook battery life and keeping system thermals easy to manage. The 1,500,000 hour MTBF and 1500G shock rating reflect the inherent durability of the solid state design.

Questions about this item

Will this 2.5" 7mm drive fit my laptop's drive bay?

The drive measures 4.96 in by 4.88 in by 0.35 in and weighs 50g, matching the standard 2.5 inch 7mm form factor used in most laptops and Ultrabooks.

What real-world speed can I expect from the SATA III interface?

Sequential read reaches up to 500 MBps and write up to 450 MBps, so boot times and application loading are noticeably faster than a mechanical hard drive.

How does the SLC Cache feature affect daily use and drive life?

SLC Cache writes incoming data to a faster portion first, boosting peak write performance and reducing write amplification for better endurance over the 1,500,000-hour MTBF rating.
