My home office has among other things a Compaq RAID array of 5 36GB drives and a few 18GB/9GB as well. MAN OH MAN that thing gets loud!
If it weren't for all the other machines and the fan that blows straight on all of them, those drives would drive me nuts. As it is, everything else combined managed to be even louder. :) How well do the save files compress? Probably not much, being psuedo-random binary, but maybe a bit... in which case if you had an NTFS partition you could make your Prime directory compressed, or periodically zip up your old save files. Just a thought. Hey, I just tried and they do compress sort of okay... 71% of original size just using default zip settings. Using max compression doesn't improve anymore than the default. Curiously, using zip -1 (lowest compression) results in the smallest file by a few ten thousand bytes... due to smaller library I'm sure. I doubt George would be interested in working in a little simple zip routine when saving/reading save files? It might slow it down too much for some folks (although honestly, it takes a fraction of a second to zip using the lowest compression level), but maybe a nice option for those looking to save a bit of space when testing large exponents. Especially if you save interim files or have 2 saved files... the space savings would add up quickly.
