Capacity and form factor
The Seagate ST1800MM0149 is a 1.8 TB 2.5" internal hard drive built for servers and storage arrays that need fast, reliable capacity in a compact bay. Its 10000 RPM spindle speed and 256 MB buffer serve workloads where consistent throughput matters more than raw bulk.
1.8 TB at 10000 RPM
The 1.80 TB capacity handles operating systems, databases and active project files with low average latency. The 10000 RPM rotation keeps random I/O responsive, but sequential transfers will saturate well before a modern SSD, so the drive runs out of steam on sustained high-queue workloads.
SAS 12Gb/s interface limits
The SAS 12Gb/s interface caps peak bandwidth at 12 Gb/s, so the drive cannot exceed that ceiling even during burst reads from the 256 MB cache. Controllers or backplanes limited to 6 Gb/s will halve the available headroom, and the physical 2.5" form factor prevents use in 3.5"-only bays without an adapter.

Questions about this item
Will the SAS 12Gb/s interface work with my older 6Gb/s SAS controller?
The drive uses a 12Gb/s SAS interface which is backwards compatible with 6Gb/s SAS controllers, though it will run at the lower 6Gb/s speed.
How can I verify the drive is performing at 10000 RPM after installation?
Check the spindle speed reported in your RAID controller BIOS or SMART monitoring tools; it should show 10000 RPM for this model.
Does the bare-drive packaging include mounting screws or a SAS cable?
The product is supplied as a bare drive only; mounting screws and a SAS data cable must be purchased separately.
