I was just reading stuff about ZFS, and wonder if it would be
beneficial for me to use it. I store a lots of multimedia files in my
HD, they usually have the size of > 1GB (e.g. 1.2, 1.7 or even
bigger), and my system is running UFS.

simply use UFS with big blocks (-b 65536 -f 8192) will be OK.

BTW i have such change in param.h on every system i have:

--- param.h~    2008-10-09 20:49:54.000000000 +0200
+++ param.h     2008-10-09 20:49:54.000000000 +0200

 #ifndef MAXPHYS
-#define MAXPHYS (128 * 1024) /* max raw I/O transfer size */ +#define MAXPHYS (1024 * 1024) /* max raw I/O transfer size */

no idea why it's not the default.

 so can I buy a new HD, say 500GB, and format it ZFS style and use it
along with other UFS? and will ZFS performs better than UFS in my

there may be slight (if any) speedup with transfer speed, and HUGE (like 10x) increase in CPU load. on slower CPUs transfers will be actually slower.
