How are some SSDs unreliable?

[azeem40]

What makes drives like the Vertex 3 unreliable when some reviews say otherwise? What makes an SSD reliable or not? Thanks.

It's mainly due to the firmware updates - which are mainly the responsibility of the manufacturer - look at this review of the OCZ Vertex 4 using different firmware: http://www.tomshardware.com/reviews/vertex-4-firmware-benchmark,3245.html
