Silver 3.5 inch SATA hard drive with exposed circuit board

Seagate

Seagate Constellation ES.3 ST1000NM0023 1TB 7200RPM 128MB 3.5" SATA internal hard drive

SKU CH-FEB4-WX4S1

1 TB 3.5" SATA enterprise hard drive, 7200 RPM with 128 MB cache for nearline storage

  • 1 TB capacity for large-scale storage
  • 7200 RPM spindle speed for responsive data access
  • 128 MB cache buffer to accelerate read and write operations
  • SATA 6 Gb/s interface for broad system compatibility
  • Perpendicular magnetic recording technology for reliable high-density storage

Enterprise Storage Drive

The Seagate Constellation ES.3 ST1000NM0023 is a 1000GB 3.5in internal hard drive built for continuous operation. It spins at 7200RPM with a 128MB cache and connects through a SATA 6Gb/s interface. The unit arrives with zero hours on the motor.

Suited for RAID and Archive Workloads

This drive fits servers and NAS enclosures that need sustained write throughput and Drive Self Test monitoring. It is not for buyers who want solid-state latency or silent operation in a desktop PC. Laptop builders and compact-system integrators should look at something else because the 3.5in form factor will not fit.

SATA 6Gb/s Interface Decides Compatibility

The single specification that decides fitment is the SATA 6Gb/s interface. Your backplane or controller must expose a standard SATA port running at 6Gb/s; SAS-only connectors will not work. Verify the host connector type before ordering.

Questions about this item

How does the 7200 RPM speed affect real-world performance in a desktop system?

The 7200 RPM spindle delivers faster sequential read and write speeds than slower drives, reducing load times for large files and improving responsiveness when the operating system accesses scattered data.

What does the SATA 6Gb/s interface mean for actual transfer rates?

The drive connects via a standard SATA 6Gb/s port, providing compatibility with modern motherboards and controllers while the mechanical media determines the sustained throughput ceiling.

Will this 3.5-inch drive fit in a standard desktop drive bay?

Yes, the 3.5-inch form factor matches the standard internal bay dimensions used in most desktop chassis, and the drive weighs 2.0 pound for secure mounting.
