SKU CH-A07D-MPD6M

A 500 GB 3.5-inch desktop hard drive spinning at 7200 RPM with a 32 MB cache and a SATA 6 Gb/s interface

  • 500 GB capacity stores large media libraries
  • 7200 RPM spindle speed delivers quick file access
  • 32 MB cache buffers bursts for smooth transfers
  • SATA 6 Gb/s interface fits standard desktop bays
  • 5 inch form factor installs in typical tower cases

Desktop storage for everyday workloads

This 3.5 inch SATA hard drive delivers 500 GB of capacity at 7200 RPM with a 32 MB cache. It suits desktop PCs that need reliable bulk storage for documents, media libraries and backups. The drive is new with zero hours recorded.

Thermals noise and typical power draw

At 7200 RPM the unit runs within normal desktop thermal limits and produces the usual mechanical hum of a spinning platter drive. Power consumption stays modest during reads and writes, fitting standard SATA power delivery without extra connectors. No active cooling beyond case airflow is required.

Build quality and daily connectivity

The standard 3.5 inch SATA form factor fits any desktop drive bay and uses common data and power cables. A 32 MB buffer helps smooth burst transfers in routine use. Buyers who need more storage capacity or faster solid-state speeds should consider other options.

Questions about this item

How do I install this 3.5" SATA hard drive and which step is most often missed?

Mount the drive in a 3.5" bay, connect the SATA data cable to the motherboard and the SATA power cable from the PSU, then initialise the 500 GB volume in Disk Management — the step most often missed is assigning a drive letter after formatting.

What maintenance or replacement will this 7200 RPM drive need later?

No scheduled maintenance is required; keep the system ventilated so the 3.5" drive stays cool, run occasional SMART checks, and replace the unit only if SMART reports reallocated sectors or the drive develops unusual noise.

What limit appears first on this SATA 6Gb/s drive during sustained writes?

The 7200 RPM platters and 32 MB cache set the sustained throughput ceiling; once the buffer fills, write speed settles at the mechanical media rate rather than the 6 Gb/s interface maximum.
