Bests & Worsts Reviews from Amazon

This is my first review. I was pretty excited to get this drive because I saw it in “good” price and for all the positive reviews, however, I did a little research and I found that this drive is SLOW, because Kingston advertise that is about 450 megabytes per second both read and write but it does at approximately 170-130. I’ll summarize the info for you. There are 3 types of firmware with this drive, the one I got has the firmware 5.0.6, which is the main problem because it slows down the drive for any reason. The other two are previous 5.0.5 firmware’s (they don’t have the problem), you can find which firmware the drive has by looking at the sticker in front of the drive, the one I got is 506ABBF0, or 5.0.6, you can also see it if you download the toolbox program from Kingston website. However, by now there is no possibility to downgrade to the previous 5.0.5 firmware, or upgrade to the already release 5.0.7 that might correct the problem. The thing is that maybe all of this was planned. First Kingston sell this drive with the 5.0.5 firmware and quality components that reaches incredible speed and everybody rate it with positive reviews, but once it has gain a high reputation Kingston now produces a low quality cheap NAND flash inside of it, several people complains that maybe the problem is far beyond the firmware, maybe is the crappy quality products inside of this drive and therefore the firmware upgrade will never come, because the problem might be the product itself. I use different benchmark programs (like crystal disk mark, as ssd or atto) and all the speeds and writes in sequential mode are around the 170-130, not even close to the 450 mb that Kingston advertise. Save your money and instead go for a Samsung or San Disk drive, I read that they do what they say about the writing and reading speeds. I’m from Mexico and I bought this drive online at amazon, I don’t know if I can return it, and if I can ¿how? Should I have to pay for the shipping cost? Now I know why the drive was “on sale”, Amazon wants to get rid of it. If you don’t believe my story and you think “It will not happen to me” first I encouraged you to just google: 506ABBF0 firmware. I regret about purchasing this drive, I WILL NEVER BUY KINGSTON PRODUCTS AGAIN. By the way, amazon shipping service are great, I receive the drive just in a few days after I place the order, shame that I just got a lemon drive.
