I20 disk driver, etc.. Should I use?

[Bob Gustafson]

I noticed that my current disk drivers are deprecated - use I20...

I ran across a note a FAQ and a HOWTO on installing i20 disk driver
support. I think I have a compatible SCSI adapter and disks.

I guess the big questions are:

1) will I get any benefit from using i20 (i.e., faster, safer, more disk
fail info, etc.)

2) will I risk screwing up my current disk data?

3) does smartd info work through i20 ?

Thanks for any info
