Best OCZ MLC SSDs
There are 15 OCZ MLC SSDs compared here. The fastest is the OCZ RD400 at 2600 MB/s read, and the highest-rated for endurance is the OCZ INTREPID 3600 (1498 TBW). Sequential reads across the group span 400–2600 MB/s.
Why this configuration
A OCZ MLC SSD is a legacy endurance choice. MLC stores two bits per cell instead of three, so these older drives take far more rewriting than a modern budget drive, at a much higher cost per gigabyte. OCZ specifically tends to be chosen here for its firmware track record and warranty support.
Usually chosen for: write-heavy secondary roles and keeping older machines useful.
Good fit: mainstream desktop and laptop builds.
