SSDs are much faster than traditional hard drives and in many cases can be noticeably faster than the older style drives. In some cases (most commonly working with RAW footage) even an SSD is not fast enough, so we recommend using the newer M.2 (flash storage) style drive which are around three times faster than a standard SSD.
In general, we recommend a two to four hard drive configuration depending on your budget and desired performance level:
Primary Drive - OS/Software (SSD) - Includes macOS and applications. An SSD is highly recommended as it will greatly improve how fast the macOS and applications startup.
Secondary Drive - Project Files / Dedicated Media Cache/Scratch (SSD) - Using a dedicated SSD for your media cache and scratch files can at times improve performance when playing and scrubbing through compositions.
Optional Storage Drive (Platter) - For long term storage where the high speed of SSDs is typically not required, a larger traditional platter hard drive is a good choice as they are still much cheaper per GB than SSDs.
