The AL13SXB60EN may just offer 600GB of storage capacity (also available in 450/300GB) but it’s probably one of the fastest 2.5-inch (15mm thick) enterprise-grade HDDs currently in the market since thanks to its SAS 12Gb/s connectivity (backwards compatible with 6, 3 and 1.5Gb/s), rotational speed of 15000 RPM and 128MB of cache it sports an average latency of just 2.0s.
