450GB 15000RPM SAS enterprise drive
The Seagate Cheetah 15K.7 ST3450857SS is a 3.5 inch internal hard drive built for servers and storage arrays that demand high transaction rates. It spins at 15000RPM and connects through a 6Gb/s SAS interface with a 16MB cache. The drive is supplied new in a lot of ten units.
Suited for multi-drive arrays.
This drive fits administrators expanding or repairing SAS-based RAID sets, JBOD enclosures or backup targets where consistent 15K spindle speed matters. It is not for systems that lack a SAS host bus adapter or backplane, nor for workloads that need larger capacity per spindle.
6Gb/s SAS interface decides compatibility
The single specification that determines whether this is the right part is the 6Gb/s SAS interface; the drive will only operate when connected to a compatible SAS controller or expander that supports this signalling rate.

Questions about this item
Will the 15000RPM SAS 6Gb/s interface work with my existing 3Gb/s SAS backplane?
The drive uses a 6Gb/s SAS interface that negotiates down to 3Gb/s on older backplanes, so it will function at the lower speed without hardware changes.
How can I verify the 450GB 15000RPM drive is healthy after installation?
Run the manufacturer diagnostic utility to check SMART attributes, confirm the 16MB cache is detected, and listen for the characteristic high-speed spindle sound during seek operations.
The listing mentions a lot of 10 drives — does each unit include a mounting tray or only the bare 3.5in mechanism?
Only the bare 3.5in mechanism is supplied; SAS data and power cables plus any server-specific mounting tray must be purchased separately.
