I've had this drive for a while now, and I've been very happy with it considering it was a humungous improvement on metal disk booting, copying...etc...etc.  But I've built a few rigs for others with the cheap $60.00 SSD's with pretty standard hardware and I soon learned my SSD just isn't performing how it should do.

I picked up a Kingston 60GB SSD for my father.  The damn thing boots in 4 seconds flat due to the ASUS quick BIOS setting being on 1 second.

I recently reinstalled Windows on my machine and I'll be lucky to get a 20 second boot now.   I decided to do some synthetic benchmarking.  It seemed to score pretty damn poorly compared to what people are getting on YouTube with a similar or same drive.

Rig:

Mushkin Chronos 480GB SSD (MKNSSDCR480GB-7)
AMD Phenom II Thunban X2 Hexa-Core 1090T Processor (3.0Ghz @ 3.9GHz overclocked)
16GB of Kingston DDR3 Memory in Duel Channel configuration
GIGABYTE 990FXA UD5 Motherboard

I'm getting pretty terrible results in the low hundreds where some are hitting 540 - 550MB/s plus.  Which is what is advertised on the internet.  The SSD is running stock firmware.  Have not touched firmware on the motherboard either.  It is in an AHCI configuration with 3 other 1TB Western Digital Black Edition drives.
Where do I start?  Formatting and installing as an AHCI drive from square one did not seem to do much.  AHCI drivers are installed.  It's on a SATA3 6.0GB/s port with a 6GB/s cable.  Something which I changed recently as I didn't realise the cable made a difference!  Learn something every day.

It has a 3 year warranty.  Should I be returning it?  I'm going to have to dig up the damn receipt!
