The new Macs with M1 chips offer great performance, however a lot of hardware devices including LTO drives need new drivers. So far this has restricted their use as archive machines.
However ATTO have recently released new drivers for their SAS and FC interfaces. A while ago Magstor released drivers for their Thunderbolt 3 LTO drives. At YoYotta we have tested both with M1 Macs and see full performance working with LTO + LTFS. You will need to install software drivers, which will be found on the manufacturer’s websites. Note that Netstor and mLogic LTO hardware will need ATTO SAS H680 drivers.
Using an M1 Mac mini with our YoYotta Automation software we were able to write and verify to four LTO drives at full speed, whilst the Mac remained cool. A big improvement over the 2018 Mac mini, which whilst powerful did get hot !
There are some limitations to these new M1 Macs and we are always updating our ‘Which Mac ?’ web page with the latest information.
