So if you need a portable hard drive with respectable storage capacity at a reasonable price, you’ll most likely pick a laptop-class drive with a 2.5″ hard drive mechanism inside. I G-Tech’s excellent for 9to5Mac, and have trusted their earlier drives for many years without any issues. (Only the very best internal SSDs now offer and, though notably with much less storage space than the drives covered in this article. See my How-To guides to, and.) If reliability is your major concern, as it generally is mine, I’d suggest you look most seriously at (featuring ultra-reliable Hitachi hard drive mechanisms) and, all of which have three-year warranties. A three-year warranty is the best you can expect from a consumer-grade external drive from a top vendor, regardless of whether it’s a.

Reliability Since MTBF and AFR are such sketchy measures of hard drive reliability, I suggest that you focus on two more tangible factors: the reputation of the manufacturer, and the length of the drive’s warranty. SSDs are just beginning to become mainstream internal drives for computers, and their capacities aren’t yet at the “more than enough space” point. Similarly, don’t be surprised if a solid state drive (SSD) costs much more and offers lower capacity than a mechanical drive. They’ll typically last longer, which is worth something.
