Questions about this item

What throughput does the SAS 3Gb/s interface cap at in practice?

The SAS 3Gb/s link tops out around 300 MB/s, so sustained reads and writes from the 10000 RPM platters will not exceed that ceiling.

What physical space and mounting does the 3.5" drive with tray require?

It fits a standard 3.5-inch drive bay and ships with the Dell tray that locks into PowerEdge hot-swap cages such as the 1950 III, 2950 III and R900.

How is the drive installed in a PowerEdge server and what step is often missed?

Slide the tray into the hot-swap bay until the latch clicks, then verify the controller BIOS sees the 146GB volume before initializing the array.
