The price of hard drive mechanisms has dropped so much in the last 12 months, it's scary. Our budget-minded Asian buddies at
MSY (Caution: world's crappiest website) have, as an example, Western Digital Caviar 8MB IDE 320GB (the really really good ones) for A$95 at the moment.
Where you have to be careful with external drives these days is not so much with the HD mech, but the case, and cheap cases are to be avoided at all costs, especially with 10.5 -- the most commonly used chipset in budget USB-only drive enclosures is the Prolific chipset, and if you have a skim through these forums wou'll find a
lot of whining about how bad these really are. Refusing to mount, refusing to unmount, refusing to format, unmounting by themselves, and loss of data are some of the problems reported with Prolific-based boxes.
Me, I would never buy a LaCie or Western Digital MyBook - they might use very good drives, but their internal electronics are very sub-standard. That 'Elements' case above is a new release from Western Digital, and despite ten minutes of precision google-fu i cannot determine its chipset ... but being USB-only means it can be either Initio (good), NEC (good) or Prolific (very very bad). I'd have to get one and open it up to find out ... but I'd never do that because I won't buy a hard drive that didn't talk FireWire.
I tell everyone the same thing -- get an external that uses the Oxford chipset, because that's the standard chip that Apple use and code for. Buying a cheap USB-based external means you have a 4 in 5 chance of it being Prolific-based.
"But an Oxford-based box alone costs $70 or more, I can get a USB one for $25!" To which I reply, "Cheapskates always pay twice." It is better to pay that bit extra for something that is reliable and problem-free.
My recommended drive enclosures are:
- MacPower IceCube2
- Newmotion Odyssey
- Vantec Nextar
- Sandisk Hardbox
- Newer Technology MicroStak
