Any other ideas? Obviously there’s more drastic measures (clone, remove from TM, format, benchmark, clone back, add to TM) and if you were better prepared ahead of time you could account for this as well (when setting up TM disk create second container on same disk, use one for TM and the other for benchmarking), but I was hoping there might be some little trick I could use to allow the benchmark to just run in place, without too much kerfuffle. In addition to disk performance, the full version of System Test (included in the full Desktop software downloads) can also evaluate your PCIe. So if you’re looking for something else that a benchmarking tool gives you, that tool likely needs write access to the TM volume, which we no longer have.Īre there any simple workarounds?

That makes sense for a lot of reasons, but it also means benchmarking a TM disk “in situ” has become difficult, say if you’re suspecting the disk is not performing so well and you want to check details. Cross platform and license free Blackmagic RAW is the world’s only truly modern, high performance, professional RAW codec that is open, cross platform and free. results with other users and see which parts you can upgrade together with.
