Well, another approach might be to just aquire an 80 GB drive and install that as a replacement. You will lose the extra capacity, but it will save you time and effort.

Given the size of the drives, I seriously doubt you will see much if any real improvements over 128MB. Under a heavy load, lots of users ast once, you might, but it will be limited. All you are really getting here is a larger cache, and as we all know, there are diminishing returns on increasing cache beyond a certain point in any given system. In this case system being smaller, old, slower drives, with a single 100baseT ethernet connection. If you had a 4000 with 4 x 250 GB drives, or a 4500 with a larger OS, faster CPU, dual Gigabit ethernet, and 4 x 400 GB drives, it would make more difference.

Should work fine. The limit is 137 GB, but if memory serves, you will get about 134 GB out of each drive, so somewhere around a 390 GB RAID 5 array.
