Yes, it's possible to check the amount of written data. Have a look at the Host Writes attribute in Intel's SSD Toolbox (Check SMART Attributes menu).
So in that screenshot, there's actually been 5.37 TB of data written? I was just reading the SSD Toolbox user guide, and it says:
This attribute reports the total number of sectors written by the host system. The raw value is increased by 1 for every 65,536 sectors written by the host. Use the Raw value for this attribute.
I'd have thought it's be easier just to say that the raw value tells you how much data's been written...
Turns out the drive isn't the 2.5" X25-M, but the 1.8" X18-M. I've been searching for reviews, but haven't found any. Does anyone know if the performance specs are the same for both G2 drives?
And was reminded to check whether my system is compatible with it as well - does it matter if I'm using a ICH9R southbridge in terms of TRIM support? My current understanding is that I just need a drive that supports TRIM, Win7, and the Intel chipset drivers.
