用電多咗，但隻牛少咗50w

Have been using ds1010+ for nearly 7 yrs?  So, reliable/durable.

It seems DS1517+ is a disappointment (to many of us).  I think DS916+ is the best 4-bay model in their product line, so far.

ps. Recently switched from Q to S (DS216+II) for the sake of Btrfs resilient data integrity, snapshot (1GB ram is good enough) and the extremely stable/versatile DSM.
