Our take on the Seagate 3.5" Cache Internal HD 500GB SATA

This is a 500GB Seagate desktop hard drive with a 3.5-inch form factor and a SATA 3 Gb/s interface. It is a bare internal drive meant to replace or add storage inside a desktop PC or enclosure, not a portable drive. Its capacity and older SATA link put it well below today's high-capacity drives, so it suits basic storage, backups and reviving older machines rather than fast or large-scale use. Buyers should expect mechanical hard drive speeds, not SSD performance.

Best forReplacing a failed drive in an older desktop PCAdding bulk storage for documents, photos and backupsBudget builds and home servers that use 3.5-inch baysExternal enclosure or NAS projects

Pros

Standard 3.5-inch desktop form factor fits most PC bays
SATA 3 Gb/s interface works with common desktop motherboards
500GB is enough for an OS, programs and everyday files
Simple bare-drive install with no software bundle

Cons

Mechanical drive, so slower than any SSD
500GB is small next to current multi-terabyte drives
SATA 3 Gb/s caps throughput below newer SATA 6 Gb/s drives
No cables, screws or mounting hardware mentioned

Questions and answers

Is this drive fast enough for a Windows install?: It can run Windows, but a mechanical 500GB drive boots and loads programs much slower than an SSD. Use it for storage and keep the OS on an SSD if you can.
Will it fit my desktop?: It is a 3.5-inch drive, so it fits standard desktop bays and many enclosures. Laptops and small-form-factor cases that take 2.5-inch drives will not fit it.
Does SATA 3 Gb/s work with my motherboard?: Yes. SATA is backward compatible, so it connects to SATA 3 Gb/s and 6 Gb/s ports, running at the slower link speed.
What comes in the box?: The drive is listed as new with all originally boxed contents included. SATA cables and mounting screws are not stated, so check your case and board for those.
Is it good for a NAS or always-on server?: It is a general desktop drive, not a drive rated for continuous multi-drive use. For a NAS, a drive built for that workload is the safer choice.
Where is the Seagate 3.5" Cache Internal HD 500GB SATA cheapest?: At Protech Supply, for $19.00, 70% under what the other stores charge, as of our latest check.
Where can I buy the Seagate 3.5" Cache Internal HD 500GB SATA?: 13 stores we checked sell it, including PayMore Sugar Land, Protech Supply, Amazon, eBay, Newegg Business.
