After years of backing up to CD's, I'm tired of the "drag 'em off the shelf, erase 'em (I use CD-RW's), gather all the stuff I want to update (using Backup), then sit there reburning 7 CD's of data and 1 or 2 from iPhoto. I guess it's time to break down and buy an external hard drive. Someone I respect suggested a 120 gig model from Transinternational. She's been using it about a month, likes it a lot and pointed me here: http://www.transintl.com/store/category.cfm?Category=405&CFID=758110&CFTOKEN =91612470&RequestTimeOut=500 It'll run me between $185 and $199 according to the site. So I have two questions: First, anybody got a better suggestion? And second, according to the site, I have to decide whether I want a 2 MB cache or an 8 MB cache (for an extra $10-15). I'm not sure what that means (he said with embarassment) but I assume it has something to do with speed? I use a 600 running 10.2.6. TIA Brian
