The Apple Time Capsule is the only external hard drive made by Apple. Overall, Time Capsule has received decent reviews by all major review sites. The one consistant problem reported with Time Capsules is that some tend to die out after a year or so of use. Honestly, all external hard drives have received some bad reviews for dying out early. The problem with Time Capsules is, the price. If a Time Capsule goes bad on you after a year, there goes $300 bucks. But remember, anything you buy... doesn't matter what it is... carries some type of risk. There are many different types of lemons, and some are more sour than others.
On the good side, Time Capsules are actually a bit more than an external hard drive. They are also a WiFi router. This makes them the ideal choice for continuous wireless backup on a Mac. Want to have fully automated backup, no strings cords attached? Time Capsule may be the best bet.
One thing to note about Time Capsules. They are designed to be a backup drive, not a drive to store extra files on. Do not get a Time Capsule if you are looking for a way to store extra stuff.
4 stars out of 5 due to price.
