Dell ST9146853SS 146GB 15K SAS drive
This Dell ST9146853SS is a 146GB 2.5-inch internal hard drive spinning at 15000 RPM. It connects through a SAS 6Gb/s interface and uses a 512n sector format. The drive is built for enterprise storage workloads and arrives in new condition.
Suits servers needing 15K SAS drives.
This drive suits servers and arrays that require a 2.5-inch 15000 RPM SAS drive with a 512n sector size. It is not for systems that only accept 3.5-inch form factors. It is also not for buyers who need a larger capacity than 146GB.
The 512n sector size decides compatibility
The single specification that decides fit is the 512n sector format. Controllers or backplanes that require 512e or 4Kn sectors will not work correctly with this drive. Verify that your hardware supports native 512-byte sectors before purchase.

Questions about this item
How much power does the 15000 RPM SAS drive draw when running continuously?
The 15000 RPM enterprise SAS drive is built for sustained operation in storage arrays; its power draw matches the standard 2.5" SAS specification for this class.
What controller or backplane is required to use this 6Gb/s SAS drive?
A SAS host bus adapter or RAID controller with a 6Gb/s SAS port and a 2.5" drive bay or backplane that accepts SAS connectors is needed.
Will this 512n sector drive work in a server that currently uses 512e drives?
Yes, the 512n native sector format is compatible with controllers and backplanes that also support 512e drives, so it can sit alongside them.
