February 22, 201016 yr I just want to mention that I've had a pretty rotten time dealing with Stardom/Raidon ST-6600 external enclosure with SIL-3726 port multiplier on it. The main reason I need it is because I've maxed out the internal bays on my system (11 drives on 7 bays) and I currently have 14 drives total. Here are some approximate numbers from me trying to tweak the system. I use parity check speed (taken on first 1-2 minutes) to get a quick snapshot of overall system's speed.. the following numbers are pretty much in chronological order of me troubleshooting it: 5 drives on ST6600, connected to RocketRAID 2310 (no NCQ) : 19MB/sec enabled NCQ : 25MB/sec connected to onboard JMicron controller : 10MB/sec connected to SIL-3132 controller : 15MB/sec reduced the drives on ST6600 down to 3 drives : 49MB/sec It's a huge bottleneck on my system (P5B-E Plus mobo, Pentium-D 3Ghz, 1GB ram, RocketRAID 2310, SIL3132) and unfortunately I can't tweak the PCI-E 'max payload size' on the mobo BIOS, which is supposed to improve the speed. I still have a few things to look into and tweak on my system... - Make sure the SIL-3726 use firmware 1.0114 - Try a different eSATA case - Try a different external enclosure, preferably one with Broadcom port multiplier chipset If there's any other Port multiplier user, I'd appreciate it if you could share your experiences here... If anyone has any more idea on what to do with my system to eek out more performance out of it, I'd very much appreciate that too!

Try re-arranging the drive layout and staggering the drives on different paths/controllers. Internal port, External port on the port multiplier, Internal port, External port on the port multiplier, , etc, etc. The rotation between controllers may help reads occur at a faster rate. Someone a while back said it helped, albeit a small amount.
