Hi guys, I really don’t frequently post here. I bought my first iMac 21.5” in 2009 and sold it recently for $150 with wireless mouse and keyboard. LOL! It’s in great shape and still working great, but it’s getting too slow for my Video editing using Filmora. So last week, I bought a 27” iMac 5k base model with 1Tb fusion drive. I already upgraded the memory to 24Gig of RAM . I’ve heard 24Gig of Ram is the ideal amount for video editing base from iMac RAM youtube tester. Anything higher doesn’t benefit you much for the money. Then I bought an external Samsung T5 500 Gb SSD for $197 ( I could not afford Apple SSD 500GB- 1TB SSD right now.) I formatted the T5 to the new MacOS High Sierra APFS and boot the system from the External T5. I’m also using a TRIM app for the external SSD. Here is the speed of the Samsung T5 via USB-C connection to iMac Thunderbolt 3. I just use the internal 1TB Fusion drive for storage. BTW, I also have the MacOS High Sierra installed in the fusion drive and converted the remaining space to APFS. Although, I don’t boot the iMac from that drive and fusion drive doesnt benefit much to the new APFS. BTW, I love the magic mouse and keyboard... Here is my old 21.5 “ My new 27” 5k Unfortunately, I haven't tested the system yet for my video editing seession.. Any recommendation or something that I’ve missed?
