Pros: None. Well, I suppose the initial setup was simple enough. Minus trying to get SATARAID5 working with UAC on Windows 7. Once that was setup, I was able to create my RAID 5 within a couple minutes. It took forever to set up, but that was expected given 4x1TB HDD in a RAID 5. Probably took over 20 hours

Cons: Where to start.... 1) Took forever to build the RAID 5 volume. Over 20 hours. 2) Rebuilds every time my computer restarts or goes to sleep. Sometimes the rebuilds will take 15 minutes, other times it'll take upwards of 3 hours 3) Random drive(s) drops every couple of weeks. No rhyme or reason to which drive drops. All drives have been independently tested using manufacturer tools and all come back clean. I've put them in different systems and they have no problems, so the HDD's are fine. The box will drop one drive, and then a couple minutes later drops a second drive bringing the RAID 5 down. I will need to pop the HDD's and reinsert them MULTIPLE times along with power cycling the unit a couple times and then eventually it'll successfully rebuild after 15 hours. Luckily I have yet to lose data with all of these drops while I've been actively using the files on the RAID. But the frequency at which this happens and the inconsistency of the fix needed means I don't trust this unit beyond its abilities as a paperweight. Rosewill support - don't bother responding. I've tried updating firmwares, drivers, the works and the issues still persist. And judging by the other reviewers on here I'm not the only one with the issue. I bought this unit thinking it'd be a great cheap RAID 5 box. I've totally learned my lesson and will fork over the extra money for a real RAID box instead of continuing to deal with this paperweight.
