Saw this zdnet.com article on facebook study of SSD reliability. This is for server class PCIe SSDs. Article gives info on failure modes seen on facebook server based systems. I've never tried flash/ssd based drives, don't have any hand's on experience/comments.
Facebook's SSD findings: Failure, fatigue and the data center: SSDs revolutionized data storage, even though we know little about how well they work. Now researchers at Facebook and Carnegie-Mellon share millions of hours of SSD experience

A Large-Scale Study of Flash Memory Failures in the Field

copy/paste from start of the Abstract
"Servers use ash memory based solid state drives (SSDs) as a high-performance alternative to hard disk drives to store persistent data. Unfortunately, recent increases in flash density have also brought about decreases in chip-level reliability. In a data center environment, flash-based SSD failures can lead to downtime and, in the worst case, data loss. As a result, it is important to understand flash memory reliability characteristics over flash lifetime in a realistic production data center environment running modern applications and system software"
