Web site copy for the Seagate Baracuda 500 GB drive used in Time Capsule:
The Seagate® Barracuda® ES enterprise hard drive is the industry’s most reliable, highest capacity 7200-RPM hard drive for 24 x 7, multidrive, business-critical applications.
Web site copy for the Hitachi DeskStar 721010KLA330:
Suggested Applications: Internal and external storage for consumer computers * Networked storage servers * Extreme gaming machines * Video editing arrays
I don't know, sounds like server grade to me. It might not be the very best hard drives in their respective line-ups, but I don't see anything misleading about the drives that Apple went with. I have a suggestion for you, Flashpoint. Instead of regurgitating all the Anti-Apple FUD in the media (mostly by tech reporters with no background in tech), why don't you do some research on your own for a change?
I don't know, Josh, there're only four Apple-related posts on the whole first page, including this one. And frankly I think there are more people interested in the Time Capsule than there are in the Everex gPC, for example.
According to Hitachi, the DeskStar is a desktop-grade drive, whereas their UltraStar is server-grade. Apple states that the same Hitachi DeskStar drives are found in their line of Apple Xserve servers and meet or exceed the 1 million hour Mean Time Between Failure (MTBF) recommended for server-grade hard drives.
"Apple states that the same Hitachi DeskStar drives are found in their line of Apple Xserve servers and meet or exceed the 1 million hour Mean Time Between Failure (MTBF) recommended for server-grade hard drives.
The DESKSTAR is in the Time Capsule."
Since the Deskstar meets Apple's requirements for a server-grade HD and is used in Apple Xserves, wouldn't it be safe to say that according to Apple the deskstar is server-grade.
Thank you for taking the time to prove yourself wrong.
Flash Point, read this: http://research.google.com/archive/disk_failures.pdf Google has a LOT of drives. They've rounded up data on their performance and failure rates. Most of these drives are "consumer" grade.
From the conclusion: "One of our key findings has been the lack of a consistent pattern of higher failure rates for higher temperature drives or for those drives at higher utilization levels."
What they're saying is that consumer grade drives aren't necessarily worse than server grade drives, even at Google's high usage. The thing you get for the extra money is a guarantee that it will work for a while longer than the other ones. And where I say guarantee, I mean educated guess.
Google's way with the disk: each machine has three (four?) straight consumer drives, each with a straight backup of the rest. No RAID. If one of the drives fails, it is replaced. Done. So much for "server" grade!
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
Once again Engadget, way to go above and beyond by making up news for Apple when there is none
The "how would you change" tags lead to more than just apple products. I sure hope there was comparable whining!
Apple claimed the hard drive in this thing would be "SERVER GRADE".
It isn't. The makers claimed it was "Desktop Grade".
FAIL.
Now, dave, they have been pretty good about having a more diverse selection of news stories as of late. You have to give them credit for that?

Flashpoint, it actually is in Hitachi's "server grade" class. It's the lowest-end server grade hard drive they sell, the Deskstar E7K500. http://www.hitachigst.com/portal/site/en/menuitem.8a3bc4482bf8cdd52d4fed26eac4f0a0/
nas + ethernet x'fer speeds = )

Resistance is futile.

According to the data sheet for Deskstar E7K500. http://www.hitachigst.com/portal/site/en/menuitem.8a3bc4482bf8cdd52d4fed26eac4f0a0/
one of the benefits is "SATA 3.0 Gb/s interface, 300MB/s burst data rate for faster data access" Time capsule is nowhere near this speed.
