I seem to recall that when Snow Leopard was released, a big deal was made about how it figures out hard drive usage. It is now base 10, or something like that. 1000 MB = 1GB, whereas before 1024 MB = 1GB. How do hard drive manufacturers figure this out? In other words, if I am looking to replace my hard drive with an SSD, am I comparing "apples to apples" (pun intended) with regards to what my "Finder" tells me I'm using and with what the hard drive manufacturer is saying its drive can handle? Thanks, and Happy New year.
