320 GB SATA hard drive
The WD3200AAJS is a 320 GB hard drive that spins at 7200 RPM with a 16 MB cache. It uses a standard SATA interface and a 3.5 in form factor. The drive belongs to the WD Caviar Blue product line and is supplied in new condition. It suits desktop builds that need basic magnetic storage.
Thermals noise and power
The 7200 RPM spindle speed produces typical mechanical drive acoustics and heat output for desktop use. Power draw follows conventional 3.5 in SATA patterns during active and idle states. No specialised cooling features are mentioned in the specifications. The shock-resistant design helps protect data during normal handling.
Build quality and connectors
The drive mounts in any standard 3.5 in bay using industry-standard SATA data and power connectors. OEM packaging means no retail accessories or cables are included. The SATA interface ensures broad compatibility with desktop motherboards and controllers. Buyers who need higher capacities or solid-state speeds should consider other options.

Questions about this item
How do I install the 3.5" SATA WD3200AAJS and what step is often missed?
Mount the drive in a 3.5" bay using four screws, connect the SATA data cable to the motherboard and the SATA power cable from the PSU, then initialise the 320GB volume in Disk Management — the step most often missed is assigning a drive letter after formatting.
What maintenance or replacement will the WD3200AAJS need later?
The 7200 RPM mechanical drive has no user-serviceable parts; monitor SMART attributes for reallocated sectors and plan replacement when the drive shows increasing error counts or unusual noise.
What limit appears first on the WD3200AAJS during sustained use?
The 16 MB cache and 7200 RPM platter speed cap sustained transfer rates; under continuous writes the drive will hit its mechanical throughput ceiling before any interface bottleneck.
