I wonder if this is the right place to ask, as the Filesystem in User Space implementation is a separate project. In Solaris ZFS runs in kernel. FUSE implementations are slow, no doubt. Same goes for other FUSE implementations, such as for NTFS. Regards, Tonmaus -- This message posted from op

I'm building another 24-bay rackmount storage server, and I'm considering what drives to put in the bays. My chassis is a Supermicro SC846A, so the backplane supports SAS or SATA; my controllers are LSI3081E, again supporting SAS or SATA. Looking at drives, Seagate offers an enterprise (Constellat
