Sonic Series enterprise SSD

The Black Diamond Memory BDSSDS256G is a 2.5 inch SATA III solid state drive built for server and storage arrays. Its 256 GB capacity and Marvell 88SS9188 controller suit administrators who need dependable read performance for boot volumes or mixed workloads.

7 mm z-height and standard SATA connectors

The drive measures 7.00 mm high, 69.86 mm wide and 100.50 mm deep, matching the common 2.5 inch bay. With no moving parts it runs silently, resists shock and reacts to sudden power loss to protect stored data from corruption.

SATA III 6 Gbps interface limits

Sequential reads reach up to 520 MBps and writes up to 470 MBps, which is the practical ceiling of the SATA bus. Buyers who need higher throughput or lower latency should consider drives that use a faster interface. MTBF is rated at 2,000,000 hours and the operating range spans 0 °C to 70 °C.

Questions sur cet article

What maximum sequential speeds does the SATA III interface allow on this drive?

The SATA III link caps practical throughput at 520 MBps read and 470 MBps write for this model.

Will the 7.00 mm height fit a standard 2.5 inch bay or caddy?

Yes, the 7.00 mm z-height matches the common 2.5 inch form factor used in most server and laptop bays.

How is the drive installed and what step is often missed?

Connect the SATA data and power cables, secure the 69.86 mm × 100.50 mm chassis with screws, then initialise the 256 GB volume in the OS — skipping initialisation leaves the drive invisible.
