Dell MY58D 3 TB SAS drive

This Dell MY58D is a 3.5 inch internal hard drive with a 3 TB capacity and a SAS 6Gb/s interface. It spins at 7200 RPM and includes a 64 MB buffer for sustained throughput. The bare drive ships with a tray for Dell PowerEdge and PowerVault servers. Condition is new.

Suited for server storage arrays

The drive fits Dell PowerEdge and PowerVault systems that accept 3.5 inch SAS drives with the supplied tray. Buyers who need a different interface or a larger capacity should look at other options. Desktop chassis without SAS backplane support cannot use this drive.

SAS 6Gb/s interface decides compatibility

The single specification that determines fit is the SAS 6Gb/s interface paired with the 3.5 inch form factor. A controller or backplane must provide native SAS signalling and the correct physical connector. Without that match the drive will not function.

Questions about this item

How often will the 7200 RPM spindle and 64 MB buffer require replacement?

Mechanical drives like this 3.5 inch SAS unit have no scheduled replacement interval for the spindle or buffer; they run until wear or failure occurs.

What limit appears first during sustained writes on the SAS 6Gb/s interface?

The 7200 RPM rotational speed caps sustained throughput before the 6Gb/s SAS link saturates.

How much noise and heat does the 5.1 unit drive produce in all-day operation?

Expect typical 3.5 inch enterprise drive acoustics and heat output; the 7200 RPM spindle and SAS electronics generate measurable warmth and audible seek noise.
