Thanks for the reply Kynan, A few 'pointers' drives read faster thn they write, and they read sequentially-oriented files faster than randomly located files. Packet size, state of the drives fragmentation and free space, and size of the file also affects speed (not just the 'time', but actual per second transfer rate). I run DiskWarrior on several drives (including all partitions, about every two weeks. Have for years. Also running Speed Disk very regularly. Since 1978 I had one drive die on me: A LaCie that had less than 48 hours of actual time on it. It was a factory dud. No great loss of data, as it was a simple backup portable. Still, a pain in the backside. LaCie replaced it after the warranty ran out. I never got around to the 'fix' in the warranty period. I have an EZQuest potable drive that has been running, almost non-stop, for 2 1/2 years. No heat generation, very reliable 911 chip, etc. The new (to me) EZQuest 7200/800FW/USB-2 drive is very nice. Close to 45 MB/sec reads, 32 MB writes. Random reads are 9MB slower, random writes are equivalent to sequential. Very nice. I advocate that people use what suits, and works for, them, in their own style of work. My relayed experience with the Ti-Book is testimonial, not prescriptive. :=) I run maintenance regularly. My cron has been altered to riun DiskWarrioor periodically, and i dump caches on reboots. All of the caches. Considering my CPU is at 667, I am happy. There are times when i reboot, and 40-50 apps shut down sequentially. it's rather astonishing when you think about it. I want to start looking for a re-conditioned 1 GB or higher Ti-Book, w/64MB of VRAM, in the Fall. I'll bite the bullet as far as OS 9 goes, but i'm keeping the Ti 667, forever, i hope. It's been through a lot and served me well. When times and fortunes (specifically , my own) change, i will swap out the Motherboard, drop a SuperDrive in it, and be on my way. ~flipper
