For about a year and a half now, the
largest capacity you could get in a single 3.5” hard disk without
accompanying enclosure was 3TB (3000GB). Eventually Hitachi released
some 4TB models, but now those drives have some competition from
Western Digital. True to its name, the new WD
Black WD4001FAEX trades the silent, steady operation typical of
such high-capacity drives for all-out high performance.
Alongside the massive capacity are a
full 7200 RPM rotational speed, 64MB of cache, SATA III 6Gbps
interface compatibility, dual-stage actuator technology for faster
seek performance, a dual-core microcontroller, and an enticing
five-year warranty, among others. The official
datasheet gives a sustained data rate of 154MB/s – I'm assuming
that's an average, but either way, using one of these as a mass
storage drive for things like video editing would be a decent idea.
Anyway, the Western Digital Black 4TB
hard drives are stamped with $339 USD MSRP's and should be hitting
computer stores over the next couple of weeks. (Via StorageReview).
