Thread: OCZ 2 Extended SandForce SSD

All OCZ 2 models are based on the SandForce SF-1200 controller. About the special features of this controller and the differences between the small and large SF-1200 SF-1500 version, we are already in our article on the OCZ LE section to SandForce SSD controller received. The only real difference between a 100 and a 120 GB SSD is actually the firmware and the other resulting from this amount of Flash memory that is kept in the drive as a backup. Previously, these were 28% for the 120 GB models are only 13%. The expanded capacity of the SSD is created not by more flash memory (hardware) but by another organization of the memory. This results in principle in a higher error rate of the SSD, for the use of the normal but is neglected. most other SSDs For use as a reserve about 7-10% of the Flash memory.



SandForce The drives are still here so very well equipped. Even with OCZ it is not possible at an old 100 GB 120 GB Vertex Vertex in a firmware update to convert. According to statements from OCZ, this is not readily available. So if ever an update is available is questionable. current extended SSDs with SandForce controller apparently have a small bug in the firmware can cause problems with SMART the all. OCZ Support Forum in this error is already discussed and also with us he has already occurred. (Smart Error after HDDERASE). After an erase of the drive with HDDERASE, it may happen that the SSD in the BIOS boot the system shows when a SMART error. These SSDs are not defective. This is virtually a SMART hoax. The problem is quite simple off by SMART in the BIOS for the appropriate drive to be bypassed.
