PX05SRB192Y - Toshiba PX05SRB 1.92TB SAS 12Gb/s 2.5-Inch SSD

Toshiba PX05SRB192Y 1.92TB SAS 2.5" SSD

The PX05SRB192Y is Toshiba’s PX05SRB at 1.92TB, a 2.5-inch enterprise drive running SAS at 12Gb/s on multi-level cell flash, rated Read Intensive. That rating describes what the host sends toward the drive, which isn’t always what the drive ends up receiving once a RAID controller sits between the two. It’s an internal part for server bays, with RoHS and WEEE compliance listed.

Key Features

• 1.92TB of capacity in a single 2.5-inch internal drive
• SAS interface running at 12Gb/s
• Read Intensive endurance rating
• Multi-level cell flash
• Toshiba enterprise PX05SRB series
• RoHS and WEEE compliant, part number PX05SRB192Y

Performance and Applications

Parity adds writing that nobody asked for. In a RAID 5 group, altering a small piece of data means reading the old data, reading the old parity, then writing both back out again. One write from the application turns into several across the drives. RAID 6 compounds it further, with a second parity block to keep current. A read-intensive drive sitting in a parity group therefore absorbs noticeably more writing than the workload above it appears to generate. Size the endurance against how the array behaves, not just what the application does.

Compatibility and Installation

You’ll need a SAS controller or backplane, a free 2.5-inch bay, and the carrier tray your chassis generation takes. Where the group runs RAID 10 rather than parity, that write multiplication shrinks considerably, which makes read intensive drives a comfortable fit in mirrored sets.

Toshiba PX05SRB192Y 1.92TB SSD for Read-Led RAID Groups

For a group where reads dominate and the RAID level keeps the write penalty in check, this sits in the right tier. 1.92TB of SAS flash at 12Gb/s, in a standard 2.5 inch bay.
