"For improved performance, choose a disk cache folder on a fast hard drive or SSD separate from your footage, and allocate as much space as possible." Hi, I'm currently running a RAID 0 with 2, Samsung 970 PRO M.2 drives (full desc. below). Now I'm a bit worried that my workstation is not optimal for After Effects, considering all my video files, my OS + AE application + Disk Cache are all going to this one drive (since RAID 0 combines both of my M.2 into one drive making it a lot faster, but less stable). Also running 64GB DDR4 RAM @ 3400 MHz. (SAMSUNG 970 PRO M.2 2280 512GB PCIe Gen3. X4, NVMe 1.3 64L V-NAND 2-bit MLC Internal Solid State Drive (SSD) MZ-V7P512BW) Here's a comment by 2 different individuals regarding this: The rules are different with SSD drives versus mechanical HDD's. SSD drives have a latency in microseconds where as mechanical drives have a latency in milliseconds. This means SSD drives can read and write far more files in a given time segment than mechanical drives. If you have an SSD then cache and media files can go there without issue. You can also include cache files easily with an OS drive on an SSD. Mechanical drives are where the separate drive philosophy really developed from. Although you can run media and cache from the same drive provided the drives and interface ie e-sata, USB3 or TB are fast enough. Firewire and USb2 would not be Eric-ADK Tech Manager You don't want the same drive/bus being used for varying read and write operations at the same time. That is a useful principle. But having cache files on the same drive as the OS and applications is in alignment with that principle; the OS is mostly read from the disk at boot, the applications are mostly read from the disk at application start, and the cache files are read and written during program run time. There is very little overlap. What you do _not_ want to do is have cache files on the same disk/bus as footage files or exported files, since those assets are being used at the same time. Todd Kopriva, Adobe Systems Incorporated After Effects quality engineering This comment however was back in 2013. I'm currently running a high end M.2 SSD that reads at 3550MB/s and writes at 3450MB/s which is incredibly fast. How much performance am I losing by having a setup where I'm running everyone on 1, RAID 0 drive using 2 M.2 SSD's? I also have a NAS HDD in order to store/archive all of my completed videos, etcetcra. Thank you.
