File Allocation Table ? Is Microsoft still pushing that? I thought that Microsoft took off with HPFS ( High Performance File System ) from OS/2 and then released a thing called NTFS. I don't think that Microsoft ever published the inner details of NTFS did they? In any case .. you don't need to worry about such things with UFS. You need to worry about other things like blocks size and fragmentation size and inode density as well as possible alternate sectors per cylinder and the maximum number of logical blocks belonging to one file. So, as an example of a UFS filesystem that is currently up and running here : # mkfs -m /dev/rdsk/c0t1d0s5 mkfs -F ufs -o nsect=228,ntrack=10,bsize=4096,fragsize=1024, cgsize=8,free=3,rps=120,nbpi=1024,opt=t,apc=2,gap=0,nrpos=8,maxcontig=1 /dev/rdsk/c0t1d0s5 6030600 so .. a different set of issues at play. For the most part you will never see those details. I hope. Also, I fail to see the benefits tweaking those UFS parameters anymore and so I hope you never need to see them. With HPFS and NTFS you never saw the details and couldn't. With UFS and ZFS I hope that you won't care to see the details and you just use them. Think ZFS as your future and you will be fine. It has all the features that a user could ever want in a filesystem and it feels like a SAN half the time.
