Hitachi has managed to shrink the thickness of 2.5-inch hard drives down to 7mm only. They’ve just announced the availability of these hard drives which have two versions, TravelStar and CinemaStar ready to go into some devices such as laptops, netbooks and AV gadgets.
The Hitachi TravelStar hard drives are meant for use in laptops or netbooks, whereas the CinemaStar is best to be used in AV streaming devices. Both models have been designed to consume lower power to suit portable devices and they’re also shock resistant and quiet acoustics.
The two models will have storage capacity up to 320GB, making them the highest capacity 7mm hard drives available. The TravelStar hard drives will have two models ready, the Travelstar Z7K320 and Travelstar Z5K320, which the major differences are the cache memory and the spinning speeds. Read the specs below for more details.
The Travelstar Z7K320 hard drive: This is the first 7mm 2.5-inch hard drive in the industry that spins 7,200rpm. The drive also has 16MB of cache memory and supports the Serial ATA 3Gbps. Hitachi claims that the drive can deliver up to an 18 percent improvement in application performance over the 5,400rpm models of the same capacity. The drive features a halogen-free design and low power consumption at just 1.8 watts during operation and 0.8 watt when idle.
The Travelstar Z5K320 hard drive: This is the lower-end ultraportable SATA 3Gbps hard drive that has 8MB of cache and spins at 5,400rpm. The drive consumes even less energy than the Z7k320 with just 1.6 watts during operation and 0.55 watts when idle.
The CinemaStar Z5K320 hard drive: Hitachi claims that this is the first 7mm hard drive designed specifically for AV-streaming devices, such as set-top boxes and DVRs. It allows these device to stay compact while offering a large amount of storage. The drive comes with 8MB of cache memory, supports SATA 3Gbps, and spins at 5,400rpm. It also futures low-energy consumption and quiet acoustics.
