Hi all,
I have a Samsung 840 EVO 120G SSD, and my CrystalDiskMark results are the following:



The problem is that I don't know what these categories mean (except Seq Read / Write). So I have 3 questions:
1. What do Seq Q32T1 / 4K Q32T1 / 4K mean?
2. What are the equivalents for these in the SSD's specification or how can I calculate them (if there isn't an exact match)?
3. What values would be normal according to the specs?

Thanks,
hazazs

I was wondering about them too. Other 840 EVO results are about 50-60 MB/s. I'm happy that mine is over 100 MB/s, but besides this these scores tell me nothing at all.
