Second is absolutely horrendous I/O performance. The file distribution it uses makes it easy to add hard drives and make duplicates. But when its balancing storage or doing its full chkdsk of every drive every 6 hours, throughput and responsiveness drops to ridiculously low levels. It also took a full 5 hours to remove a drive, when there was no more than 20gb of data that needed to be shifted to the other drive. Its all a bit half baked at the moment, to be honest.
At the very least, my suggestion is to not put any data you'd like quick access to on drives that are part of the storage stack. You can just as easily make your own shares on drives that you havent added.
Interesting... I've had no issues with accessing any of the info on the network shares at all. (5 HDDs totaling 1.5TB) I've had 2 DVD image streams going to 2 media devices and somebody accessing the shares on 2 PCs at the same time. No slowdown or hesitations at all.
It works wonderfully until you try and access stuff while copying something, leading to the balancing act. Everything is copied to the main drive, it bounces it to other drives, and theres so much I/O going on, and with no I/O prioritization, it can take forever to do certain basic things.
I really dont understand the need for doing a chkdsk on EVERY disc, every 6 hours. Its a home server for crying out loud, and with data duplication, is it really going to be a crisis if theres a small bit of data thats screwed up on one drive? Hell, the crazy disc activity from the constant chkdsk itself is probably going to wear the drives into failure.
When I was finally fed up with it, I had to jump through all these hoops to reorganize the data. I put in another drive, which was big enough so I could fit pretty much everything on it, and I made the mistake of moving rather than copying the data. Moving deleted data as it was copying, which prompted the drive balancer to start shifting around data while I'm still moving, completely clogging the system up. It took 10 hours to shift about 100gb of data on modern SATA hard drives, in the same system...ridiculous. It should have taken no more than an hour, and even thats at a conservative 30mb/sec. Then to "remove" the nearly empty drive, which should only have had about 20gb of data, took 5 hours. Which wasnt abnormal...it told me "this may take several hours." Wtf?
I really dont understand the rationale behind their disk bouncing system. Why it can't just maintain a unified share, and balancing/duplication for several drives without that nonsense is beyond me.
I liked pretty much everything else about it, but I absolutely refuse to use it until they implement I/O priority, or at the very least, pause balancing and chkdsk when no one is accessing data.
