Hitachi Global Storage Technologies today announced its first enterprise-class 4TB desktop hard drive.
Seagate said it is the first hard-drive maker to achieve the milestone storage density of 1 terabit (1 trillion bits) per square inch on a disk platter.
Western Digital’s latest My Passport Studio has a solid build and multiple connections, but slow transfer speeds and a preinstalled security app hamstring an otherwise decent drive.
Western Digital on Thursday revealed that its new My Book Thunderbolt Duo, a two-drive desktop RAID array equipped with Thunderbolt connectivity, is now available for purchase for $600 (4TB capacity) and $700 (6TB capacity).
