Hard disk drives encounter errors from time to time, so it’s a good thing that most have the ability to recover data anyway. But RAID systems usually have their own error recovery capabilities and can be thrown off when a hard disk pauses I/O. So it’s a good idea to use hard disk drives that allow you to disable or limit error recovery in RAID systems.
Have you ever wondered if mounting a hard disk drive on its side or even upside-down affects its lifespan or reliability? According to every drive manufacturer, it’s perfectly acceptable to mount a hard disk drive in any orientation as long as it’s not tilted and has sufficient cooling.
I’ve written a few times about my quest to build the ultimate home storage/server rig. But one issue was surprisingly vexing: What kind of case has room for a dozen or more hard disk drives? In this update, I’ll talk about the various options as well as the one I ultimately picked: The NZXT H440 (and a Corsair power supply).
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.
Seagate is one of the world’s most-successful hard disk drive companies, consistently ranked first in overall sales for a decade. The company is respected for their high-end products, but is aggressively moving into the world of smaller hard disks for laptops and portable storage as well. The company’s mainstream “Momentus” portable hard disk family has kept pace with the industry, but Seagate will soon break away with a major jump in areal density. Using public information, and the first product in this line, we will consider what Seagate’s eighth-generation Momentus family will look like.
One reason I decided to work with the folks at DCIG to collect data for their Small Business Storage Array Buyers’ Guide was to learn more about the various products in the space. One difference I noted in these small arrays, which usually hold 4 to 8 drives, is their use of hard disk drive carriers or sleds. There are pros and cons to both approaches, but I was pleased to see that all arrays so far include everything needed to install a drive.
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.
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, […]
That didn’t take long! Less than a month after Hitachi introduced their 2 TB enterprise disk drive, Xyratex has announced that they will offer the drive in their OEM storage systems. The A7K2000 is 7200 rpm 5-platter design with a 3 Mb/s SATA interface: Not exactly high-end, but backed by the reputable folks at Hitachi […]
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.
