First off... Hi everybody! I found this site when searching for an answer to the below question. Hopefully somebody can help. I'm putting together my first Mac. It's pretty much a beast as I'll be using it for audio (Cubase 5 with a lot of VSTs and up to 24 channels at once) and video editing (Final Cut - a lot of HD, some uncompressed), as well as generic family photoshop stuff. It's (probably) a pretty typical configuration for us not-quite-rich and missing-mortgage-payments to-pay-for-this-ourselves types: An early 2008 2.8 dual quad core mac pro with 18GB of memory. It will have an 80GB Intel X25-m SSD boot/application disk with 4 Seagate 7200.11 1.5TB disks in RAID 0/stripe (so it's all internal) for data using the OS for RAID, and of course dual external drives for time capsule backups (4 disks striped without any mirroring is risky!) with the original 340GB drive used for Carbon Copy images of the SSD (yes, I'm paranoid - rightfully so, long story) I would like to know if the SSD or the 4 disk stripe is the best option for swap and /tmp performance. I'm a little concerned about wear on the SSD (if that is the better solution). My (very limited) understanding of SSDs is that the cells do wear out. While this may not be an issue for simple boot/app drives which are (relative to swap) infrequently accessed, it could be a serious one for something that gets as much I/O as swap. I'm also curious about the difference in performance between system/OS RAID 0 and hardware RAID 0. I don't think I'll be maxing out all 8 cores for a while, but how does it compare with say 4 free cores vs a RocketRaid card? If you have pointers to benchmarks and/or real life experience with these various configs, please reply. Thank you in advance for your help!
