ltfs

Hi, i have a windows 10 pc with DELL perc H200 and an IBM Lto6 drive It works but i suspect the controller is a bottleneck, i only transfer zip/tar files (quite big) but sometimes the copy slows down, and almost never exceeds 150/180 mb/s I bought an used Dell Adaptec PCI-E 12Gb SAS Controller...

Either somebody here, or if you can point me to forums anywhere on the interwebs that I can sign up to to talk to people who use these with any regularity just to ask some questions only they would know. Specific question example - does LTFS (tape file system) store fine grained timestamp...
