I was lucky to get a new 500 Gb portable hard drive for Christmas. It was one of the Western Digital Passport series, a very small USB drive. I already had 4 of these, 2 with 160 Gb, 1 at 250 Gb and 1 at 320 Gb. One might think it all adds up to a lot of giga-bytes, but with hard drives, the larger capacity are much more useful than multiple drives that add up to that capacity.
Also laying on my desk are 3 different 2.5 in bare drives that have been removed from various notebook computers, 1 at 160 Gb, and 2 at 100 Gb. I have an external dock I can plug these into, but what do I use them for? They are too small to hold an image of my current Mac Book Pro hard drive. It becomes a bother to split backups over multiple drives. So they just kind of sit there, like paper weights.
I also have a 3.5 in, 500 GB bare drive sitting next to them. It failed awhile ago. It is still under warranty so I need to send it back to Maxtor to get a replacement, but I have not got around to it. I guess I just have drives coming out the Ying Yang.
My new minimum sizes:
2.5 in drive – 500 Gb
3.5 in drive – 1 Tb
