JAPANESE MANUFACTURER Hitachi has released two small 500GB, 5,400RPM hard disks.
The company claims that its Travelstar Z5K500 drives are the industry's highest capacity, one-disk, 7mm z-height hard disk drives.
Each drive has 8MB of cache memory, a SATA 3.0Gbps interface and consumes just 1.8W of power in operation. The hard drives are Advanced Format-ready, feature a sound output of 2.1 bels during seeks and, optionally, are available with bulk data encryption.
Bulk data encryption scrambles data using a key as it is being written to the disk and then descrambles it with the key as it is retrieved.
The Travelstar Z5K500 drive family is also being offered in Enhanced Availability (EA) models in capacities of 320GB and 500GB, which are designed and fine-tuned for applications needing "always-on" protection. These are typically low transaction environments including blade servers, network routers, video surveillance and compact RAID systems.
Hitachi says it will start shipping these hard drives this month, and the 500GB model has already been announced as the base for G-Technology's new G-Drive slim portable hard drive that is expected to become available in early 2011. µ
