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.
Drobo: First Impressions

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!

Posted by Stephen in Enterprise storage, Everything, Terabyte home on 25. Aug, 2009 | View Comments
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, [...]

Western Digital announced this morning the world’s first “1 TB mobile hard drive!” But although the news is great for storage-hungry folks looking for a portable external drive, it doesn’t quite mark a sea change in the storage industry since this drive cannot be used in (most) laptops.

The inexorable march of areal density continues with this week’s release of two breakthrough two-platter hard disk drives:
First up is Seagate, with their next-generation 3.5″ “7200.12″ drive family. Boasting 500 GB per platter, the drives are initially offered in 500 GB, 750 GB, and 1 TB versions, but we expect a 1.5 TB three-platter and [...]

There is a battle shaping up in the enterprise storage industry. On one side are those who see flash storage as an upgrade for the disk drive, and on the other are those who see it as a cache between the CPU and the drive. It’s a fundamental difference of opinion – flash chips can [...]
Big Little Disks Are On The Way

The relentless march of hard drive capacity is about to reach its next cantonment as 500 GB 2.5″ drives begin to arrive this month. These little half-terabyte wonders will continue the downward pressure on price and challenge flash-based drives just as they stake their claim in the main stream of the market.
Specialized Desktop Hard Drives

I will begin my overview of the specialized hard drive market with the ubiquitous desktop disk drive. While just about any drive could be used in a desktop computer, the class is generally defined by what it lacks – compact size, power efficiency, exotic interfaces, special drive features, and high performance are all [...]

Posted by Stephen in Enterprise storage, Terabyte home on 03. Aug, 2007 | View Comments
Lately, there has been a lot of buzz in the enterprise storage arena about whether so-called “enterprise drives” are really any better than plain-Jane hard drives in Enterprise applications. This came to a head with the controversial findings of Google and CMU, but it’s been simmering under the covers everywhere from TiVo communities to [...]
