3TB SATA desktop drive

This 3TB 3.5 inch drive connects over SATA 6.0Gb/s and spins at 7200 RPM with 64MB cache. It suits desktop workstations that need bulk storage for documents, media libraries or backup images.

Standard 3.5 inch mounting

The drive fits any 3.5 inch bay using the usual four screw holes and standard SATA data and power connectors. No adapter or special bracket is required for typical tower or rackmount chassis.

SATA 6.0Gb/s throughput ceiling

Sequential transfers top out at the SATA 6.0Gb/s interface limit so sustained reads and writes cannot exceed that bandwidth. Random I/O performance is bound by the 7200 RPM rotational speed and mechanical latency.

Questions about this item

What practical speed limit does the SATA 6.0Gb/s interface impose on this DT01ACA300 drive?

The SATA 6.0Gb/s interface caps the maximum theoretical transfer rate at 6.0Gb/s, so sustained reads and writes from the 7200 RPM platters cannot exceed that bandwidth.

What physical space and mounting does the 3.5-inch form factor require?

The drive needs a standard 3.5-inch drive bay and uses the usual bottom or side screw holes for secure mounting in a desktop chassis.

How is the drive installed and which step is often missed?

Connect the SATA data cable to the motherboard and the SATA power cable from the PSU, then initialise and format the 3TB volume in the operating system — the formatting step is frequently overlooked.
