SFS partition size

[Caius]

Hey. I'm currently prepping a 320GB IDE harddrive to use in my Amiga. What is the largest partition size SFS will allow? I'm using version 1.277. And I'm using AmigaOS 3.9 (before you ask;) )

According to the old website (http://www.xs4all.nl/~hjohn/SFS/features.htm), the limit is about 2000 GB.
I don't think this is different for the current version of SFS.

My current drive is 1500 GB.  So I am almost to the limit of SFS ability.

Just checked an old changes.txt file.
These are the current max partition sizes (from version 1.245  and up):
 
- SFS now refuses to format too large partitions and existing too large
  partitions are mounted read-only. The current partition size limits
  of SFS are:
   64 GB with   512 bytes/block
  128 GB with  1024 bytes/block
  256 GB with  2048 bytes/block
  512 GB with  4096 bytes/block
    1 TB with  8192 bytes/block
    2 TB with 16384 and 32768 bytes/block

I believe that information was later corrected. For sfs 1.x the max size is 128gb. For 2.x it can handle much larger partitions.

You are correct.
 
Quote from the changes.txt file:
 
1.254 (4.3.2006)
- The limits mentioned in the 1.245 notes were wrong, sorry. The actual
partition size limit of SFS 1.x is 128 GB, no matter which blocksize
you are using. Changed the checks to the actual limits. You can
continue to use too large partitions, but you may get "disk full"
errors (instead of a trashed partition) even if there is still free
space on the partition.
 
Edit:
for 'SFS2' partitions the limit is 1 TB, but it can be more depending on the blocksize, with 32KB/Block it's 64 TB.

What is the size limit for SFS 2.x?

Is there SFS 2.x for 680x0 systems?

Is SFS 2.x regarded as "working reliably"?

I read on forums before that there were 2 different SFS 2.x by 2 different people. :confused:

Anyone knows the answers?

Does anyone know the partition size limit of PFS?
FFS?

See my previous post.

Thanks for the answers so far. I have another one. For each partition, what's a good value for the "Buffers" field in HDToolBox? I'm guessing that setting it too high will simply cost a lot of memory without actually giving a performance gain. I'm using the internal IDE port on a A4000, if that matters.

Somewhere between 100 and 150 buffers will do.
