File system's properties
Not counting security, which file system (ext3, ext2, NTFS, FAT32, FAT16, Drivespace 3 and others I'm too stupid to know about such as mac's and solaris') is the best at speed, non-recoverable errors (not considering the hard drive's errors), effective use of drive space, non-fragmentation, recoverability from power loss, etc.?
How reliable is memory? If I set up a ram drive, will I have more data loss or less (concerning data decay NOT power loss)?
