Enterprise Capacity Drive
The Seagate ST4000NM0125 is a 4TB 3.5-inch internal hard drive built for servers and storage arrays that require the SAS 12Gb/s interface. It spins at 7200 RPM with a 128MB cache to sustain heavy read and write workloads. The SLC NAND flash component supports data integrity features in demanding environments. This drive suits administrators who need high-capacity, enterprise-grade storage on a 12Gb/s SAS fabric.
Not For Direct Desktop Use
Systems without a SAS host bus adapter or backplane cannot connect this drive, so standard PC builders should look elsewhere. Laptop upgrades and small-form-factor enclosures are unsuitable due to the 3.5-inch form factor. Buyers who need a different interface protocol or a smaller physical size must choose another product.
Interface Is SAS 12Gb/s
The single specification that determines compatibility is the SAS 12Gb/s interface, which requires a matching controller or backplane. Without that connection the drive will not function in the target system. Verify the host hardware supports this interface before purchase.

Pitanja o ovom artiklu
How much heat and noise does the ST4000NM0125 produce during continuous 7200 RPM operation?
The 3.5-inch drive spins at 7200 RPM with a SAS 12Gb/s interface; sustained enterprise workloads generate typical mechanical-drive heat and audible seek noise.
What host connector and controller does the ST4000NM0125 require to function?
It needs a 12 Gb/s SAS backplane or HBA with a compatible SAS cable; the drive uses a standard SAS data and power connector.
Can the ST4000NM0125 share a SAS backplane with older 6 Gb/s SAS drives?
Yes, the 12 Gb/s SAS interface auto-negotiates down to 6 Gb/s, so the 4 TB drive operates alongside legacy SAS devices on the same domain.
