Here is the result of my SSD

What do you think?

At least it shows that the speed is far above the SATA II specs (300 Mb/s maximum). So it only can be achieved on a SATA III port (600 Mb/s).

Results of only one Samsung SSDS 840 Pro in my desktop shows some different values. More high for reading  "Seq" section about 525 Mb/s ----- 512K block about the same ----- 4k block about 34 Mb/s ----- 4K QD32 about 400 Mb/s (That is about twice the speed).
But for write I have lower values for "Seq" + 512K blocks ----> below 400 Mb/s, more high for 4K blocks ----> 123 Mb/s, and also for the last 4K QD32 block ----> 366 Mb/s

These different values could be part of using other drivers, chipset, settings etc. of the Toolbox and as I use RAID-0 from time to time, the AHCI-mode can not be used (I have to change setting in BIOS already).
