As a SAN drive for home this is great. No real problems. The MyCloud is very flaky. It only works sometimes. Awfully slow when it does work. I went ahead and let it update to OS5 before storing any data on it. It took 11 days to finish indexing! And that was only after doing what support said to NOT do. I rebooted. It seems to get hung after a couple of days and has to be rebooted so it can actually finish indexing.
5 stars as a home SAN. 1 star as a MyCloud for accessing files from outside of home.
And .. yes I have a very good ISP with fast access. Everything else I run has no problems.
