1 TB enterprise SATA drive

This 1 TB Seagate Constellation ES.3 drive spins at 7200 RPM and carries a 128 MB cache. It is built for desktop or server workloads that demand sustained throughput on a standard SATA 6 Gb/s link. The bare drive arrives without cables or mounting hardware.

Check SATA port and 3.5 inch bay

Verify that your motherboard or controller offers a free SATA 6 Gb/s port and that the chassis has an open 3.5 inch drive bay with mounting points. A SATA data cable and a SATA power connector from the power supply are also required for installation.

Fits RAID arrays and bulk storage

The drive slots into multi-bay enclosures or direct-attached backplanes where 3.5 inch SATA drives are supported. Its 128 MB buffer helps absorb burst writes in RAID configurations while freeing faster solid-state media for operating system and application duties.

Questions about this item

Does the ST1000NM0033 ship with cables or a mounting bracket, or do I need to buy them separately?

The drive is supplied as a bare unit only; SATA data and power cables plus any 3.5" mounting hardware must be purchased separately.

Should I choose the 128 MB cache version or is there another capacity option for this model?

This specific model ST1000NM0033 provides 1 TB capacity with a 128 MB buffer; no other cache sizes are offered for this part number.

How does the 7200 RPM spindle speed affect everyday desktop performance?

The 7200 RPM rotation delivers faster sequential throughput and lower access latency than slower drives, improving boot times and large-file transfers in a typical desktop.
