I got this cheap old sas HGST SSD1600MM. In the manufacturer's brochure it says that all models have a 1600GB "full initial capacity" and then they have have different models with different capacities (200-1600GB). Does this mean that the all drives have 1600gb physically installed and the unaccessible capacity is used for wear leveling?


Also, I got a sun branded model which is a HUSSM1640 but its capacity is actully 200GB on the label while the cheat sheet says it should be a 400GB model. In software it also has a unique model number that's different from the HGST one. Quite a weird drive.
