Questions about this item

What does the 600 MBps external transfer rate mean when the drive is installed in a server?

The 600 MBps figure is the maximum throughput the SAS 6Gb/s link can sustain when the drive is seated in a compatible hot-swap bay; actual sustained speeds depend on the controller, queue depth and workload mix.

What does the SAS 6Gb/s interface cap in real-world use?

The SAS 6Gb/s link caps the drive at 600 MBps external transfer rate, so the storage controller and backplane must support at least 6 Gbit/s lanes to avoid bottlenecks.

What bay size and mounting style does this 2.5" drive require?

It fits a single 2.5" SFF hot-swap bay such as those found in the HP Modular Smart Array 2040 series and other servers with matching SFF trays.
