SLC, MLC, and TLC are different types of Nand, each with different physical properties, you can't "flash" one to another. This renders the idea impossible although the concept is intriguing.
1. If you write more than 50% of the free space on the drive all at the same time, it will slow down temporarily until the write is finished. Once the write is finished the drive will take a moment to perform some "cleanup" and then will return to the faster state.
Example: You have 75GB free...
There really isn't anything to "fix" because 3 weeks or 6 months from now you might be down that 20MB/s again through your pattern of usage. Very few drives stay at the very top of their performance 100% of the time. A secure erase will reset everything to out of the box performance though.
We may not be able to get it back without a secure erase. What is the date of your drivers? Right click the line above (in device manager) and select driver and see the date it was published.
You do have a fairly old chipset and even with newer drivers, you may not get the speed. Newer drivers...
They are absolutely related in a fixed way.
IOPS x (the file size you are measuring the IOPS for) = throughput. Change the IOPS and you change the throughput, change the file size and you change the throughput.
@ Berryracer,
His partition is aligned, it shows in AS-SSD as fine. He is using a SATAII SSD and motherboard, you are using a SATAIII SSD and motherboard, you are going to blow him out of the water on AS-SSD scores.
He is also using a SF based SSD which in AS-SSD scores lower in writes because...
Yes, the Windows Toolbox can't update an SF based drive when Windows is running from it. Bootable tools allow the drive to be secondary and update anything.
For the OCZ drive, use the bootable tools: http://www.ocztechnologyforum.com/forum/showthread.php?105168-NEW!!-OCZ-Bootable-Toolbox-PC-Edition
Just make sure you are in AHCI mode, you won't have to worry about drivers this way.
Because of the driver listed in AS-SSD. "asahci64". When connected to the Intel SATA3 ports and the proper Intel RST drivers are installed, the driver says "IAstorA"
You have the drive connected to the wrong SATA ports. You have them on the ASMedia SATA3 ports and thus you have lower performance.
Connect the drive to one of the 2 Intel SATA3 ports.
The 560/430 benchmark is also done with ATTO, not AS-SSD.
It is not common for the SSD to develop bad sectors.
It is common that new Nand may have some, which are found and noted during the initial manufacturing and bad block scan. Which is what the OP is most likely seeing.
