Never buy crappy, consumer-grade SSDs for use in production servers/RAIDs. This might sound obvious but at the company I used to work for, through a series of bad decisions by management and cheapness, we ended up with the cheapest consumer SSDs you can imagine powering all of our storage.

This turned into a nightmare spanning years of failed hard drives and a continues cycle of ridiculousness. Drive failed after a few days, gets taken out, sent back to manufacturer and then replaced with another equally crappy drive destined to fail within days/weeks.

Our ops people were going to the data center multiple times per week to replace failed drives. Lesson I learned: cheaping out on system-critical hardware and software can have long standing consequences and in the end usually doesn't end up actually saving money when you account for time employees have to spend dealing with issues that result from it.
