Enterprise bulk-data drive
The Seagate Exos 7E8 ST4000NM005A is a 4TB SAS 12Gb/s internal hard drive built for 24×7 enterprise workloads. It spins at 7200 RPM with a 256MB cache and uses conventional magnetic recording technology. The 3.5-inch form factor fits standard drive bays in servers and storage arrays.
Suited for high-capacity RAID and replicated systems
This drive suits IT professionals who need up to 550 TB per year workload rating and a 2 million hour MTBF rating in multi-drive environments. On-the-fly error correction and rotational vibration design help maintain consistent performance. It is not for buyers who need a different interface, a smaller form factor, or a drive rated for lighter desktop workloads.
SAS 12Gb/s interface decides compatibility
The single specification that decides fit is the SAS 12Gb/s interface; the drive requires a backplane or controller that supports this protocol. A 512e sector format ensures broad compatibility with existing enterprise infrastructure. Confirm your system accepts SAS drives before purchase.
