Much ado about Time Capsule

A little “much ado about nothing” … No server class hard disk in Apples Time Capsule. You can find rants about that here (on german) and here (on english). You don´t really need an enterprise class harddrive in the Time Capsule. The Time Capsule HD should switch off as often as possible to save power. Enterprise HD´s like the Ultrastars are qualified for 24/7 operations. For home use this is nonsensical. More interesting to me for a backup device is the error rate: 1E15 with the Deskstar 7K1000 (The corresponding Ultrastar has the same bit error rate) means one error every 120 TB. That´s acceptable for such a device. (especiallly when you consider that normal consumer drives delivers such an error every 12 TB). I do not assume they use ZFS in the Capsule … My problem with the Time Capsule is the single disk. I saw to many hard disk dying to trust a single hard drive, even enterprise FC high-end ones …
