Testing HD Performance & RAM In MDD Under X.4 or X.5
Posted by: trag on 2012-07-15 19:35:26 What do folks recommend to use to test RAM for defects in an MDD under 10.4 or 10.5. I guess I could boot into 9.2 and use the old standby, RAMometer. Also, what do folks recommend to test hard disk performance? I have here an MDD which has been working mostly trouble-free for years with 1.5 GB of RAM. I have a .5GB stick on hand I pulled from a G4 Mini and I'd like to add it, but I'm concerned that I'll screw up a good thing. No reason for my suspicion, just paranoia. So I want to test the RAM after I add the odd stick. Also, after a hard drive failure, I've finally installed a 6880M in the machine, and configured it to boot off of mirrored volumes in OS9 and 10.4 and 10.5. I'd like to compare the disk performance I'm getting now, mirrored volumes on a 6880M, to what I was getting off of singleton drives on the built-in bus. If I've taken a small performance hit, it's worth it for the redundancy. But I had to jump through enough installation hoops to get this working, that I want to confirm that it's not running at something like 25% of what a drive on the built-in would run at. I haven't noticed any substantial performance hit, so it's probably fine, but numbers are reassuring. Thanks.
