Silicon Power Slim S55 480GB SATA SSD

The Silicon Power Slim S55 is a 2.5-inch internal solid-state drive with 480GB capacity. It uses TLC memory and a SATA III interface for consumer PCs and ultra-slim notebooks. The 7mm height fits Ultrabooks and standard drive bays alike.

SATA III 6Gbps interface limits and compatibility

The drive connects through the SATA III 6Gbps interface, which is backwards compatible with SATA II 3Gbps ports. Sequential reads reach up to 520 MBps and writes up to 480 MBps on this bus. Random 4KB performance peaks at 43,000 IOPS read and 24,000 IOPS write. TRIM, Garbage Collection, NCQ and RAID support are included.

7mm form factor decides fit

A 7.00mm z-height determines whether the Slim S55 fits a specific laptop or desktop bay. The drive measures 69.85mm wide by 100.00mm deep and weighs 2.78 oz. Shock resistance is rated at 1500G and vibration resistance at 20G.

Questions about this item

Will the 7 mm height fit my ultrabook's 2.5" bay?

Yes, the drive measures exactly 7.00 mm tall, matching the standard slim 2.5" slot used in most ultrabooks and thin laptops.

Can I use this SSD with an older laptop that only has SATA II ports?

The SATA III interface is backwards compatible with SATA II 3 Gbps, so the drive will work though sequential speeds will be limited to the older bus.

What daily workload does the 43,000 random read IOPS figure translate to?

That level of 4 KB random read performance keeps operating system boot, application launch and multitasking snappy on typical office and web workloads.
