I will be running Mac OS 7.5.5 and will be formatting it with the version of Disk Tools that came with that OS. (It would be about 80 GB and I would partition it quite a few times to make sure that no partition is over 4 GB).
hum... My notes say that the max vol size was increased from 4 GB to 2 TB in System 7.5.2 (July '95). Is this not correct?
This computer will be run as a webserver and filesever so anything to boost the transfer speed would be nice. So far, the system is holding up very well and to make sure that this continues, I will put the website it is serving on a RAM disk (~20 MB) so the access time is almost immediate.
As for HDD speeds, if I do get a new HDD is there any benifit to a new drive controller?
If the system has a lot of RAM and VM is off (so the OS and running apps are mostly memory resident), and the web pages are all in a RAM Disk, the speed of your HD or its controller will mean little. IOW, the only advantage will be on the disk you use for file serving.
Also, does drive cache over 2 MB even matter? If the HDD performs typically better than the bus itself is there *any* justification in a larger cache?
It depends on the type of i/o activity you do. System 7 has a crummy scatter-gather algorithm for the cache.
Larger disk caches will usually increase performance on sequential read-heavy applications. But will decrease performace if you write (takes longer for the mostly-full cache to flush to disk).
