I have a server I want to run FreeNAS on, that only has 1GB of memory. My question is can I use FreeNAS and use the UFS filesystem with only 1GB of memory? I only want to use CIFS/SMB and FTP at this time. I have 3 of 4 drive spaces loaded, with drive 1 40GB, drive 2 80GB, and drive 3 120 GB. These are SATA drives. Thanks.
