According to wikipedia, it was once used to refer to a bit level, rather than block level type of striping with parity. These people seem to be making up their own system and it sounds like snakeoil. > the drive is partitioned in 2. > 1/4 of the 2TB QLC is used in Raid level=2 mode. > > The reason is to emulate an SLC with QLC. > Increase speed & longevity by 4x > By reducing size 1/4. I can't tell if you are talking about one drive, or two.

Which two? raid10 is "2 raids in 1" ( raid0 and raid1 ).
