I wouldn't call them typical overall, but there have been a few notable mess ups. Like the 128GB drives on the 2012 MBA models, that apparently had lousy firmware that caused premature failure of many of them.
The problems that are cropping aren't so much with the SSD technology itself, but with things like the support hardware and firmware that have bugs, or software that isn't quite optimized to handle SSD storage, which MUST be treated a bit differently from traditional hard drives.
Hard drives aren't perfect either though.Ask anyone who's bought Western Digital drives recently, or the Seagate 1.5TB drives back in 2008, or ask an IT person about the reputation of Hitachi "DeathStar" drives.
Meanwhile, we've been using a cheaper, slightly slower form of SSD for years and haven't really paid much attention to it. It's in our smartphones and tablets.
