Being one of the few remaining mechanical components of the computer system, the hard disk drive is also one of the major power consumers. A spinning hard disk platter effectively turns power into heat, working contrary to user expectation. Not surprisingly, most hard disk drive manufacturers have implemented a number of power saving features, reducing the impact of disk drives on one’s electric bill. But one power saving feature from Western Digital has come under increasing fire: the Intellipark system found in their Caviar Green hard disk drives is a serious liability when used in many “always-on” scenarios.
Both Seagate and Western Digital have much to gain from these transactions. Western Digital becomes a full line giant of the industry, a credible competitor, and a successful supplier to OEMs. Seagate also retains its credibility in the market, but also gains access to Samsung, one of the strongest electronics companies in the world. Time will tell which of these companies got the better deal.
This regular series features highlights from the week. I was pretty busy at the Exec Event this week, but did sneak out a few posts about VMware hardware compatibility (SATA/PATA and FCoE CNAs) as well as a review of the Samsung pico-projector I bought for Tech Field Day 4.
SP-H03 Pico Review: Keen touch control but dim lamp, auto-drain battery; tiny but with clunky accessories. A niche product.
Last year, as the pre-release hype around the iPad was reaching its peak, dozens of companies announced their own tablet computers or “pads”. Some predicted doom for Apple’s device even before it was released. After all, how could premium-priced Apple compete with the volume PC makers and all the factories in China? Pretty well, it turns out. Almost a year later, no tablet has even come close to Apple’s mighty iPad, and it currently boasts 95% market share. Where are the iPad killers?
What hard disk drive should you use in a Drobo? Stick to 1.5 or 2 TB models from Seagate and Western Digital, and watch for great deals!
Are “enterprise” drives worth the extra cost in a RAID enclosure? The reason I ask is I’ve had 2 of 4 Seagate ‘consumer’ (7200.12) drives fail in my (Other World Qx2) enclosure. The two drives that failed were maybe a year old, well short of any ‘MBTF’ expectation. Enterprise drives cost nearly twice that of consumer drives.
Single-parity RAID is under attack. Caching is the hottest trend in storage. The end of the high-performance disk drive is imminent. What happened? Increasing areal bit density has caused disk capacity to grow much faster than disk performance. A presentation at Storage Networking World by Ronald Bianchini of Avere exposed the mathematics of this phenomenon.
Although the Drobo “storage robot”, essentially a friendly home RAID enclosure, has long impressed me, it never fit my laptop-oriented lifestyle. But my home network has changed with the addition of a 2009 Mac Mini server, so it was time for me to pick up a Drobo of my own!
Hard disk drives, like the engines in our cars, have been massively upgraded over the last two decades. Although massive IOPS and horsepower get all the headlines, energy-efficient designs deserve a look as well. Manufacturers have recently introduced some new tricks to coax out a little more performance and capacity from a lot less energy, […]
