When box is checked (without buffer flushing), in case of power failure or sudden reset, data losses may be vast and uncontrollable, you may even lose data unrelated to files being written because file-system updates occur with same principles. Without this checkbox, if failure occurs at any point, you'll always have at least the old version of data. But many programs are aware of that (all programs which are designed with safety in mind) so, for example, they don't just overwrite data in place: they create a new file, write data there, flush cache to ensure it's written, then remove the old file. Usually data losses may only be possible in cases of faulty hardware or unclean shutdowns (sudden power outages, heat protection kick-ins, BSODs, etc.). I understand there could be a roundabout driver solution here, but I want to stay within warranty and try to find out what's going on so I can get Dell to support this and issue an official solution. I updated my Intel RST drivers and that didn't help. See also Slow SSD performance (Toshiba 1GB NVMe). In case it's helpful, I learned about that checkbox in the first place from reading, but this doesn't explain to me why CDM would still be fast. Does anyone know what's going on here? My concern is that according to that checkbox description, I should NOT have it checked since my drive doesn't have its own power supply, but AS SSD is so slow, I'm concerned other programs may be affected. ![]() When running a benchmark using the program AS SSD on an NVMe drive, When the second checkbox seen in the image below is unchecked, the drive gets terrible write performance in AS SSD (see first benchmark screenshot below), but not in CrystalDiskMark (see last screenshot) however, if I check that box, then AS SSD performs well.
