QNAP Systems, Inc. is pleased to announce Western Digital Caviar Green 2TB (WD20EADS) SATA hard drive is now supported by the entire TS-109/ 209/ 409/ 509/ 439/ 639/ 809 /809U-RP and the latest TS-119/ 219 Turbo NAS series.

'The latest 2TB Caviar Green hard drives from Western Digital consume up to 70% less power than two 1TB hard drives and are relatively quiet in operation. These hard drives are ideal for customers requiring higher capacities and the right balance of energy conservation and ensured reliability. The maximum capacity can be extended up to a total of 16TB now on a TS-809 or 809U-RP' says Andy Chuo, Product Manager from QNAP. The complete HDD compatibility list is available here.

Japanese hardware manufacturer Logitec (≠ Logitech) released the new LHD-ED line of 1.5TB external hard drives, variants of which are segregated on the basis of connectivity options:

• Model LHD-EDU2 provides just USB 2.0
• Model LHD-EDFU2 provides USB 2.0 and FireWire
• Model LHD-EDSAU2 provides USB 2.0 and eSATA

Connectivity aside, the variants are identical in measuring 42 × 225 × 132.5 mm, weighing 1.1 kg (around 2.42 lbs), and feature hard drives with spindle-speeds of 7,200 rpm. They are backed by a one-year company warranty, and will go on sale by the end of this month at prices ranging between US $282 and $304.

Hitachi Global Storage Technologies (Hitachi GST) today announced the CinemaStar C5K500, a 2.5-inch hard drive with up to 500GB of audio video storage capacity designed for digital video applications that require compact design and low power usage. This fourth-generation small form factor CinemaStar drive delivers a balance of capacity, cool operation and ruggedness to provide manufacturers with more eco-friendly options for slim digital video recorders (DVRs), set-top boxes and surveillance systems. The CinemaStar drive is designed for use in continuous "24x7" applications and has a read/write power specification that is 22 percent lower than previous models.

Seagate today introduced its Constellation family ofnew enterprise storage solutions for Tier 2 nearline storage applications. The two new drive models, the 2.5-inch Constellation and the 3.5-inch Constellation ES hard drives, include a combination of features that enable high capacities, increased power efficiency, enterprise-class reliability, and data security. Both drives also include PowerChoice from Seagate, which decreases power consumption by up to 54% for record power savings in enterprise environments.

"The need for greater storage capacity will continue to expand in multiple directions and dimensions, but there will be an increasing scrutiny of all storage system purchases, with an eye to decreasing power consumption, footprint, and cost per GB in unprecedented ways," said John Monroe, a research vice president at Gartner. "Performance will not be ignored, but a flexible balance of capacity, cost per GB, power and speed will become more crucial in fulfilling end-user storage demands at varied price points."

Seagate today announced two new members of its award-winning Cheetah enterprise-class hard drive family: the Cheetah 15K.7 hard drive and the Cheetah NS.2 hard drive. Current economic challenges have put even more focus on reducing spending to ensure long-term business sustainability. For businesses that have an existing investment based on a standard 3.5-inch enterprise infrastructure, the new Cheetah drives bolster sustainability through easy drive/system integration, and provide improved levels of system performance, capacity, reliability, and lower power consumption.

Broadening its storage solutions for Mac, WD today introduced two new external hard drives - the My Passport for Mac portable drive and the My Book Mac Edition external hard drive. Pre-formatted for Mac and offering a simple USB interface, these drives offer the ever-growing Mac community reliable, easy-to-use storage. WD's latest Mac-ready drives work seamlessly with Apple Time Machine or other popular Mac backup software to provide protection for consumers' valuable digital photos and media.

No, seriously don't. An engineer at Sun Microsystems' Fishworks lab discovered that yelling at your hard-drive causes sharp (yet momentary) increases in the hard-drive's latency. The engineer demonstrated this by yelling a portion of a server holding a RAID JBOD array, while monitoring its IO/s and latencies of the drive he was yelling at it. Each time he yelled at it, there was a surge in the drive's latency. The engineer posted his demonstration on YouTube. Now you know that yelling at your hard-drive isn't going to help, or is it? This opens up some interesting topics to research on, of how the rather loud environment enterprise hard-drives are put through in high-density storage environments impact on them, and to what extant vibration dampening helps them.
