Your backup drive just died, and the last one you grabbed off a shelf was a 5400 RPM desktop disk with a 1-year warranty. You needed enterprise-grade storage that holds up under sustained workloads without blinking. This is it.
The WD Gold 4TB (WD4004FRYZ) spins at 7200 RPM with a 256MB cache, pushing sustained transfers up to 267 MB/s over SATA 6 Gb/s. Western Digital projects 2,000,000 hours MTBF and a 0.44% annualised failure rate. That's a drive built for the job, not a consumer platter repackaged.
Drops straight into any standard 3.5-inch bay. No adapter, no fiddling. RoHS compliant. Assembled in Thailand. Carries a full 5-year limited warranty from Western Digital.
$439 RRP. One drive. Five years of coverage. Sorted
