- 4 TB capacity stores large datasets
- 7200 RPM spindle delivers fast sequential throughput
- SAS 12 Gb/s interface enables high-speed host connectivity
- 5 inch form factor fits standard drive bays
- Self-encrypting 512N sectors protect data at rest
Dell 4 TB SAS internal drive
This Dell ST4000NM0135 is a 4 TB internal hard drive built for servers and storage arrays that require SAS connectivity. It suits administrators adding nearline capacity to compatible Dell enclosures or JBODs.
Thermals noise and power in normal use
The 7200 RPM spindle and SAS 12 Gb/s interface operate within typical enterprise drive thermal and acoustic envelopes for 3.5 in form factors. Power draw follows standard enterprise HDD profiles under sustained read-write workloads.
Self-encrypting 512N sector format
Hardware-based self-encryption with 512-byte native sectors secures data at rest without host software overhead. Buyers needing non-SED drives or 4Kn sector formatting should select a different model.

Questions about this item
How is the 3.5 in SAS drive installed in a server bay, and what step is often missed?
Slide the drive into a hot-swap carrier, secure the screws, then connect the SAS cable and enable the SED encryption key in the RAID controller before first use.
What maintenance or replacement will the 7200 RPM HDD need later?
Plan to replace the drive after its rated workload limit; monitor SMART reallocated-sector counts and keep firmware current to extend service life.
What limit appears first under sustained 12 Gb/s SAS writes?
The 7200 RPM mechanical throughput ceiling is reached before the 12 Gb/s interface saturates, capping sustained transfer rates.
