 In 2010, some manufacturers (notably Samsung) introduced SSD controllers that extended the concept of BGC to analyze the file system used on the SSD, to identify recently deleted files and unpartitioned space. The manufacturer claimed that this would ensure that even systems (operating systems and SATA controller hardware) which do not support TRIM could achieve similar performance. The operation of the Samsung implementation appeared to assume and require an NTFS file system. It is not clear if this feature is still available in currently shipping SSDs from these manufacturers. Systematic data corruption has been reported on these drives if they are not formatted properly using MBR and NTFS.
