Horrible 5.0.6 firmware ruins SSD
*update 1/12/14* Firmware is not the issue, Kingston switched to asynchronous NAND
Seems I found the real culprit after speaking with several SSD experts on various tech forums, get ready for a class action lawsuit Kingston. Here's the scam, Kingston switched to cheap asynchronous memory chips that don't run in parallel after the first few months of production.
That means single channel bandwidth instead of multiple channels like earlier v300 SSD's. Instead of running at 200mhz, its running at 66mhz. This effects read and write speeds enormously.
Kingston hid this fact by using solvent on the original labeling of the memory chips, then printed their own logo on top. Kingston does not manufacture any memory themselves. When SSD was shipped out for review it used quality Toshiba 19nm NAND but Kingston used solvent on chips labels and printed their own. This was odd, but the reason for it soon became obvious. After only a few months they switched to inferior quality chips with the same Kingston label.
NO OTHER SSD MANUFACTURER ERASES ORIGINAL NAND LABEL AND PRINTS THEIR OWN ON TOP!
This is FRAUD in my opinion and Kingston could very well be seeing a class action lawsuit coming there way for this stunt. Other SSD makers have tried this crap in the past and got busted. They were forced to RMA all the drives back to synchronous memory chips which cost much more.
Kingston switched to cheaper quality NAND without saying a word. Firmware for Sandforce SSD's cannot cause you to lose 70 percent of read and write speeds. Lesson learned, never buy anything from Kingston again, they are criminals.
