Hi All,
   I recently got in a pair of S25CF - Adtron Corporation drives, these are slower (1999-ish) DUAL CF -> 50 pin 2.5" SCSI drives.  I've now gotten the 2mm to 2.54mm 50 pin breakout adapters and am working my way up to trying to test them for install on the upcoming refresh of an Indy & Indigo.    No one knows just how fast they are, but I know they aren't faster than 10MiB/s, likely slower to around 5MiB/s.  Anyway, I've just ordered used, older, SanDisk Ultra II CF cards that *SHOULD* work but it's a gamble....more on all that later.

Anyway to prepare for this (and possibly other SSD-style mods).  I was hoping for any info about optimizations for SSDs on SGIs (both under XFS and Irix setup).  Like:

1. Removal of swap space entirely (Indy has MAX 256MB already installed) or at least swap space on a secondary mechanical drive and NOT on an SSD (during Irix setup and operation).
   
2. Possible filesystem mount options like "don't record file last access dates" or some such things to speed up file systems operations on slow drives.
   
3. Volume alignment tricks, can we do anything inside FX to push entire partition creation to be aligned to 2KiB or such boundaries?
   
4. XFS cluster size being a correct multiple of NAND, assuming 2KiB for now until I know more.
   

I have OTHER SGIs/Linux that can access SCSI drives so if these operations cannot be done during install, I can always prep a drive on another machine (to skip the FX stage on a new machine) to put specific XFS cluster values and the like on a drive before OS installation.  I know Linux can read (possibly create?) SGI volume partition schemes.  So if the ENTIRE partition scheme needs to be setup on Linux to be aligned, then placed in a running Irix machine to format XFS V1 or V2, I can do that!

Anything else I might not know?

So, Info?  Please post what you got, I'd like to at least have this be a good place to establish SSD practices to get as much speed as possible from SSD/SD/CF SCSI solutions.

Thanks!
