When your data centre is bursting with unstructured files, you need storage that never quits, even under constant load. The Seagate Constellation ES.3 (ST1000NM0023-RFB) 1TB 7200RPM 128MB SAS Hard Drive is a rugged 1 TB enterprise hard drive designed for 24×7 bulk storage, delivering reliable performance while keeping power costs low.
Usages of a 1 TB Hard Drive
Ideal for servers that handle massive daily backups, virtual machine libraries, or high-volume transaction logs, this drive fits seamlessly into rack-mount arrays, enabling continuous data capture without slowing down your workflow.
Benefits of Seagate Hard Drive
- Reliability: MTBF of 1 400 000 h ensures years of uninterrupted service.
- Energy efficiency: Low idle (4.84 W) and typical (8.93 W) power draw reduces operating costs.
- Speed: Consistent 7 200 RPM rotation provides predictable latency of 4.16 ms.
- Capacity: 1 TB storage lets you consolidate large data sets on a single disk.
- Compatibility: SAS interface delivers 6 Gbit/s transfer rates for fast data movement.
Seagate Hard Drive Performance
Choosing this drive means you get enterprise-grade durability without the premium price of higher-capacity models. Its 128 MB buffer smooths large file transfers, while the 3.5-inch form factor fits standard server bays, making installation straightforward.
Built for harsh environments, the drive tolerates shocks up to 70 G operating and 300 G non-operating, plus vibration resistance, so you can rely on it even in busy data halls. The wide operating temperature range (5 - 60 °C) ensures stable performance year-round.
