I'm replacing my mac's HD due to suspicious behavior that seems to point to a failing disk. My current WD is still under warranty, however, I have to send it in before they send me a replacement and I just can't be computer less for any amount of time (working on an animation for my undergrad thesis). For all that I mentioned above, I decided to get a new HD to replace the current one before sending it in for warranty and keep the replacement they'll send me as a back up. I currently have a 750GB WD Scorpio Black 7200RPM 2.5" SATA HD 16MB Cache and I'm wondering if I should get another similar WD, a 750GB Seagate Momentus or if there are any better options out there (that are not SSD because I can't afford it atm). Advice, please? If you've had any good or bad experiences with those or other HDDs, I'd love to hear them.
