Seagate

Seagate Constellation ES.3 ST2000NM0033 2TB 7200RPM 128MB 3.5" SATA internal hard drive

SKU CH-XWAN-70FA4

Enterprise-class 3.5" SATA hard drive delivering 2000GB capacity with 7200RPM speed and 128MB cache

  • 2 TB capacity stores large media libraries
  • 7200 RPM spindle speed speeds up file access
  • 128 MB cache buffers bursts for smoother throughput
  • SATA 6 Gb/s interface enables fast host transfers
  • 5 inch form factor fits standard desktop bays

Product identity

The Seagate Constellation ES.3 ST2000NM0033 is a 2000GB internal hard drive designed for desktop systems that need high-capacity bulk storage. It spins at 7200RPM and provides a 128MB cache to smooth sustained read and write workloads.

SATA 6Gb/s interface limits

The drive uses the SATA 6Gb/s interface, which caps real-world throughput below the theoretical maximum. Sequential speeds will not exceed the bus limit, and random I/O performance is constrained by mechanical latency inherent to rotating media.

Pre-installation checks

Verify that your motherboard or controller has a free SATA 6Gb/s port and that the chassis can accommodate a 3.5in drive. Ensure the power supply includes a spare SATA power connector and that the operating system supports drives of this capacity.

商品問答

Should I pick the 2TB model or a different capacity?

The ST2000NM0033 is the 2TB version; choose it when you need 2000GB of storage in a single 3.5" bay.

What does the 7200RPM rating mean for everyday use?

7200RPM gives faster sequential throughput and lower access latency than slower drives, helping with large file transfers and boot times.

Is the SATA 6Gb/s interface a bottleneck for this drive?

The 6Gb/s SATA link caps the burst rate at 6Gb/s, but sustained reads from the platters stay well below that limit.
