DELL ST4000NM0023 4TB 7200RPM 3.5" SAS internal hard drive
A 4 TB, 7200 RPM SAS hard drive with 128 MB cache in a 3.5 inch form factor, supporting hot-swap operation
- 4TB capacity stores large datasets
- 7200RPM spindle delivers fast sequential access
- 128MB cache accelerates frequent read operations
- SAS interface supports dual-port enterprise connectivity
- Hot-swap capability enables drive replacement without downtime
Capacity and interface
The drive provides four terabytes of storage on a twelve gigabit per second SAS link. It is built for servers and workstations that need consistent throughput rather than peak burst speed.
Build integration
The three and a half inch form factor fits standard drive bays and hot-swap carriers. The SAS interface requires a compatible controller or backplane; it will not operate on a SATA-only host.
Sustained workload behaviour
A seven thousand two hundred RPM spindle and one hundred twenty eight megabyte cache deliver steady sequential performance under continuous read and write loads. The Constellation line is engineered for twenty four by seven operation rather than intermittent desktop use.

Fragen zu diesem Artikel
How does the 7200RPM spindle speed affect sustained transfer limits?
The 7200RPM rotation speed and 128MB cache deliver consistent sequential throughput for sustained workloads on the 6Gb/s SAS interface.
What noise, heat or power impact should I expect from the 3.5-inch SAS drive running all day?
The 3.5-inch form factor and 7200RPM motor produce typical enterprise drive acoustics and heat; ensure your chassis provides adequate airflow for continuous operation.
Which SAS controller or backplane must I already have for this 6Gb/s drive to work?
You need a SAS controller or backplane that supports 6Gb/s SAS (SCSI-2) and 3.5-inch hot-swap bays to install and use this drive.
