Hi, I'm new to FreeBSD (and UNIX in general), and I have read through the handbook and various websites to gain some insight on this question, but haven't found a concrete solution yet, and I'm hoping you guys can help. I'm wanting to build a FreeBSD 7.0 based file server for a small/medium company that I work for and I've got the box up and running, samba is working fine, the only problem that I can see is that the array that I installed (3ware 9650SE) with 3 WD 1TB SATA drives in RAID 5 seems to be performing very slowly. This isn't just an issue of slow access over the network for the Windows users, but when I transfer a few GB from directory to directory on the array, or from the system disk to the array or vice versa. Now, this is how I set up the array. I installed the card, popped in the drives. The card bios found the drives and allowed me to setup in RAID 5. Then, FreeBSD booted and found the "disk" as da0. I want the entire array to be one big chunk of space. In other words, I don't need a bunch of slices or partitions (or DO I? I'm still very new to the whole slice vs. partition concept) I typed newfs /dev/da0 . A ton of numbers went across the screen, then I mounted /dev/da0 at /usr/home/storage. It works, but perhaps I missed a step that would have made things easier/perform better, etc. Besides creating the file system a different way, what would be an optimum stripe size for the array? I will using this for storing, basically, a TON of word documents and email messages, and a few large .pst files. So, the average file size will be in the 25-100K range, but a few 1-2GB files. Thanks for ANY and all help. If this question has been asked and answered a million times, please forgive me and just point me to the place where I can read up on this issue. Thanks, RF
