Dell Constellation ES.3 4TB SAS drive
The Dell Constellation ES.3 ST4000NM0023 is a new 4TB 3.5-inch internal hard drive built for servers and storage arrays. It spins at 7200RPM, uses a SAS 6Gb/s interface and provides a 128MB cache. The package includes an R Series caddy for direct mounting in compatible Dell bays.
Suited for SAS-based servers and arrays
This drive fits systems that accept 3.5-inch SAS drives and can supply the required 6Gb/s connection. It is not for laptops, small-form-factor PCs or any chassis limited to 2.5-inch bays. Buyers whose hardware only offers a different drive interface or form factor should look elsewhere.
SAS 6Gb/s interface decides compatibility
The single specification that determines fit is the SAS 6Gb/s interface; the host controller and backplane must support this exact standard. Verify that your server or enclosure lists SAS 6Gb/s support before purchasing.

Questions about this item
What SAS controller or backplane do I need to connect this 3.5" 6 Gb/s drive?
A SAS host bus adapter or RAID card with a 6 Gb/s wide port and a 3.5" drive bay with SAS backplane or breakout cable.
Will this 7200 RPM 4 TB SAS drive work in my older 3 Gb/s SAS enclosure?
Yes, the 6 Gb/s interface negotiates down to 3 Gb/s so the drive will operate at the slower link speed.
How can I confirm the 128 MB cache and 7200 RPM speed are active after installation?
Check the drive model ST4000NM0023 in BIOS or a SMART utility; it will report 7200 RPM and 128 MB buffer.
