Dell SAVVIO 15K.3 146GB SAS drive
This Dell SAVVIO 15K.3 ST9146853SS is a 146GB 2.5-inch internal hard drive spinning at 15000RPM with a 64MB buffer. It uses a SAS 6Gb/s interface and ships new with an R Series tray for direct installation in compatible bays.
Suits servers needing 15K SAS spindles
The 15000RPM rotational speed and SAS interface target enterprise servers and storage arrays that require high IOPS from a 2.5-inch form factor. It is not for desktop PCs or laptops lacking a SAS controller, nor for users who need larger capacity than 146GB.
SAS 6Gb/s interface and 15000RPM speed
The single specification that decides fitment is the SAS 6Gb/s interface combined with 15000RPM spindle speed; the host system must provide a SAS backplane or controller that supports this signalling rate and the physical 2.5-inch bay with R Series tray mounting.

Domande su questo articolo
Is the 146 GB model the only capacity available for this drive?
The drive is offered as a single 146 GB capacity with a 15000 RPM spindle and 64 MB cache.
What does the 15000 RPM spindle speed mean for daily server workloads?
The 15000 RPM rotation gives low latency and high IOPS for transaction-heavy applications such as databases.
Will the SAS 6 Gb/s interface run at full speed on a 3 Gb/s backplane?
The 6 Gb/s SAS link auto-negotiates down to 3 Gb/s on older backplanes, limiting peak throughput to that slower rate.
