Enterprise 15 000 RPM SAS drive
The Seagate Cheetah 15K.5 ST3146855SS is a 3.5 inch internal hard drive built for enterprise storage. It spins at 15 000 RPM with a 16 MB cache and connects through a SAS 3Gb/s interface. The 146 GB capacity and 4 ms average seek time suit high-transaction workloads. Condition is refurbished.
Suits high-IOPS servers not capacity-first arrays
This drive fits servers that need low latency and sustained random I/O for databases or transaction logs. The 15 000 RPM spindle and SAS signalling support hot-swap bays in rack enclosures. Builders who need more storage per bay should look at larger-capacity alternatives. Buyers without a SAS backplane or HBA cannot use this drive.
SAS 3Gb/s interface decides compatibility
The single specification that determines fit is the SAS 3Gb/s interface. A compatible SAS controller or backplane is mandatory; the drive will not operate on any other bus. Verify the host system provides a SAS 3Gb/s port before purchase.

שאלות על הפריט הזה
At 15000 RPM, what is the first limit that appears during sustained use?
The SAS 3Gb/s interface caps sustained throughput at 3 Gb/s, so the bus becomes the bottleneck before the mechanical speed does.
How much noise, heat or power does the drive produce when running all day?
Enterprise 15000 RPM drives run hotter and louder than desktop models; expect noticeable heat and audible seek noise in continuous operation.
What must the system already have for this drive to work?
A compatible SAS 3Gb/s controller or backplane is required; the drive will not work with other port types.
