Finally, a 4TB hard drive. That’s one more than three!
MOST OF US DON'T NEED 4TB hard drives. Most of us don’t even need 3TB drives. Unless you create, edit, or store lots of high-definition video; have backups of all your machines; have a massive lossless audio library; or…. You know what? Maybe we do need 4TB drives. After a couple of years making do with puny 3TB drives (like animals!), it’s time to get 25 percent more stuff into our 3.5-inch drives. Though other drive makers offer 4TB external drives, Hitachi GST is the first drive maker to give you 4TB on the inside. And didn’t your mother or mother-equivalent teach you that it’s what’s on the inside that counts?
We’ve been expecting 4TB drives since Seagate’s 1TB/platter 3TB drive in the January 2012 issue, but the four-platter 4TB 7,200rpm drive we’ve been dreaming of isn’t here yet. Instead, we get Hitachi’s Deskstar 5K4000, which packs a full four terabytes into a standard 3.5-inch drive, but on five platters, not four. The platters have a maximum areal density of 443Gb per square inch. The 5K4000 has 32MB of cache, a 6Gb/s SATA controller, and a spin speed of 5,400rpm.
