4 TB SAS drive for Dell servers

This 4 TB SAS hard drive operates at 7200 RPM and ships with a Dell caddy. It is built for Dell PowerEdge R720, R720xd, R730, T620 and MD3200 systems. Buyers who need a different interface or a smaller form factor cannot use this drive.

Thermals and power in normal use

The 3.5 inch mechanical design produces typical heat and vibration for a 7200 RPM spindle. Acoustic output matches standard enterprise SAS drives under sustained workloads. Power draw follows the Constellation series profile for sequential and random access patterns.

Build quality and daily mounting

Each unit is tested with Hard Disk Sentinel and only drives reporting proper health are shipped. The included caddy enables direct insertion into supported Dell chassis without extra hardware. Cosmetic imperfections on the enclosure do not affect function. Drives are packed in OEM or retail packaging that may vary.

Questions about this item

How do I install the 3.5" SAS drive with its caddy in a Dell R720 server?

Slide the caddy into an empty 3.5" bay until the latch clicks, then connect the SAS data and power cables to the backplane.

Will the 7200 RPM spindle bearings need replacement during the drive's life?

The sealed bearing assembly is rated for continuous operation and is not user-serviceable; no scheduled bearing replacement is required.

At what point does the 6 Gb/s SAS interface become the throughput bottleneck during sustained writes?

Sequential transfers saturate near the 6 Gb/s link speed, so the interface limit appears before the 7200 RPM media can deliver higher rates.
