The "disconnect" issue is generally related to Sandforce based devices.
Its a lot better on later devices / firmware and does depend on the
controller / MB they are connected to.
We have ~ 1000 SSD's in production most being consumer grade Sandforce
based and disks, from various manufactures, drops are still fairly rare
now; I'd estimate ~ 1 or 2 per month.
Samsung 840 Pro's seem pretty good too for consumer devices.
Regards
Steve
