What this drive is

The IBM 90Y8926 is a new 146GB 2.5-inch internal hard drive that spins at 15000 RPM with a 64MB cache. It connects through a SAS 6Gb/s interface and is supplied with an installation publication, warranty information and a safety flyer. The tray type is hot-swap.

Who it suits and who it does not

This drive suits servers or workstations that require a 2.5-inch SAS drive running at 15000 RPM for high-throughput workloads. It does not suit systems that only accept SATA connectors, nor buyers who need a 3.5-inch form factor or capacities above 146GB.

The spec that decides fit

The SAS 6Gb/s interface is the single specification that determines whether this drive will work in your system; the host must provide a compatible SAS backplane or controller.

Questions about this item

How do I confirm the 15000 RPM SAS drive is performing correctly after installation?

Check that the system BIOS or RAID controller detects the 146GB capacity and SAS 6Gb/s link speed, then run a SMART self-test to verify the 2ms average latency and 64MB cache operation.

What ships with the 90Y8926 and what must I source separately?

The box includes the 2.5-inch 146GB hard drive, an installation publication, a warranty sheet and a safety flyer; a hot-swap tray, SAS cables and a compatible 6Gb/s controller are not included.

Which capacity and speed version of the 90Y8926 should I select for a 15K SAS workload?

This model is the 146GB 15000 RPM variant with 64MB cache and SAS 6Gb/s interface; no other capacity or RPM options exist under this part number.
