Here are the results: The following results are from testing from the drives connected via port multiplier to the RAID DSA3GPX8-4E controller. Note ada0, ada1, ada2, ada3 and ada4 did not have the SATA2 jumpers, while the rest of the drives did.

With read cache disabled, the speed is 7.89 MB/s while read cache enabled allows speeds at around 600MB/s root@superstorage ~]# arcconf setcache 1 logicaldrive 1 roff Controllers found: 1 Command completed successfully.

I need to thank Sum my "helper" on getting this testing done for me. Thanks. -- View this message in context: http://freebsd.1045724.n5.nabble.com/Addonics-SIS3124-Controller-and-T-tp4220441p4390480.html Sent from the freebsd-hardware mailing list archive at Nabble.com.
