Enterprise SSD for SATA arrays

The Black Diamond Memory Sonic Series BDSSDS1T is a 1 TB 2.5 inch SATA III solid-state drive built with TLC NAND and a Marvell 88SS9187 controller. It targets server and storage-array builders who need reliable capacity on the legacy SATA bus. The 7 mm height fits standard drive bays and hot-swap trays.

SATA III throughput ceiling

The drive connects through the SATA III 6 Gbps interface, so sequential reads top out at 520 MBps and writes at 460 MBps. Random I/O and sustained writes will sit well below those peaks. Builders planning all-flash arrays must budget for the interface bottleneck rather than the NAND potential.

TLC endurance for mixed workloads

TLC flash trades write endurance for cost, making this model suited to read-heavy or mixed workloads rather than write-intensive logging or caching tiers. The 2 million hour MTBF rating supports always-on operation, but lifetime writes are limited by the memory technology. Choose a different drive class for heavy write duty.

Questions about this item

Should I pick the 256 GB, 512 GB or 1 TB Sonic Series SSD?

The 1 TB model BDSSDS1T gives the most space for OS, applications and data on a single 2.5 inch SATA drive.

What does the 520 MBps sequential read mean for everyday server use?

It lets the Marvell 88SS9187 controller serve large files and boot images at near SATA III line speed, cutting load times versus mechanical drives.

Does the SATA III 6 Gbps interface limit the 460 MBps write rate in practice?

Yes, the SATA III ceiling caps sustained writes at the rated 460 MBps, so the drive cannot exceed that throughput regardless of workload.
