Capacity and interface
This 500GB desktop hard drive uses a SATA 3.0Gb/s interface and spins at 7200 RPM with a 16MB cache. It suits builders adding bulk storage to a desktop PC or replacing an older mechanical drive. The 3.5-inch form factor fits standard drive bays. It is not for users who need solid-state speed or a smaller 2.5-inch form factor for laptops.
Sustained workload behaviour
The drive delivers an average seek time of 8.2ms and average latency of 4.16ms during continuous read and write operations. Native command queuing helps order requests efficiently when the drive handles multiple simultaneous tasks. Write performance averages 9ms. It is not for workloads demanding the low latency and high IOPS of flash storage.
Thermals noise and power
The manufacturer highlights whisper-quiet acoustics and a rugged, efficient system design for normal desktop use. Best-in-class operating and non-operating shock resistance supports reliability during daily operation. The bare-drive packaging means no retail accessories are included. It is not for silent builds that require fanless or solid-state components.

Questions about this item
How loud and hot does the ST3500641AS run during continuous 7200 RPM operation?
The 7200 RPM spindle and 16 MB cache are designed for whisper-quiet acoustics and rugged, efficient system design, keeping noise and heat low even under sustained load.
Which SATA host interface and power connector must my desktop already provide for this bare drive?
A SATA 3.0 Gb/s data port and a standard 15-pin SATA power connector are required; the drive ships without cables or brackets.
Will the 500 GB BarraCuda 7200.9 work reliably alongside an older SATA 1.5 Gb/s controller?
Yes, the SATA 3.0 Gb/s interface is backward compatible with 1.5 Gb/s hosts, and native command queuing helps maintain performance on legacy chipsets.
