Hey Stephen,
I can recommend the workflow at my workplace.
We use an mTape Thunderbolt LTO-6 drive (https://www.mlogic.com/products/mtape) and Quantum Ultrium 6 Data Cartridges which hold around 2,400GB of data per tape. To format and archive to these tapes we use a free LTFS software called LTFSQuicktools. Only problem I’ve ever had was recently, and the solution was just to not have Adobe Creative Cloud running when using these products.
It’s pretty speedy – for example right now I’m copying 730GB of rushes and it’s estimating an hour and a half.
Any other questions please don’t hesitate to ask.
Kind regards,
Francis
