Have you tried last release version?
Under windows I can easily read/write about at ~75MB/s without doing nothing but formatting it. My friend has the same drives in Linux, he says he can get ~50MB/s on his very low end system (crap cpu and only 256mb of ram). Under FreeBSD, my write is at best ~6MB/s and read is about ~9MB/s. The CPU, amount of ram, etc are all better than both the above boxes so don't think it's bound by anything externally like that. From what I read, the partitions aren't aligned correctly? What's going on here? For start to finish, how should I partition and format these so they don't suck? diskinfo: Code: [r...@fire2 ~/drive]# diskinfo -v /dev/da3 /dev/da3 512 # sectorsize 2000396746752 # mediasize in bytes (1.8T) 3907024896 # mediasize in sectors 243201 # Cylinders according to firmware. 255 # Heads according to firmware. 63 # Sectors according to firmware. dataconfig.cfg: Code: #http://forums.freebsd.org/showpost.php?p=76148&postcount=38 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 3906961408 1 4.2BSD 4096 32768 bsdlabel/newfs: Code: bsdlabel -R /dev/da3 datadrive.cfg newfs -S 4096 -b 32768 -f 4096 -O 2 -U -m 8 -o space -L u2 /dev/da3 fstab: Code: /dev/da3 /u3 ufs rw 2 2
Can you post detail about your controller? Can you post cache and error recovery mode pages for your disks? Dmesg sample?
