[Greg Ball] “My problem is that I’ve been editing for years on E-sata drives. So all of my projects are on those drives. How would I be able to access those drives on a new Mac or iMac?
I really don’t want to spend $6K on a new mac. “
If your physical drives are over 5 yrs old they should probably be replaced. Some studies show a 20% annual failure rate if the HDD is 5 yrs old.
If you mean you’ve been using eSATA drives (in general) for years but the HDDs themselves are newer, you could put them in a 2-bay or 4-bay Thunderbolt or USB-C chassis like one of these: https://eshop.macsales.com/shop/hard-drives/External-Enclosures/3.5-Inch-Drives
I have several 4-drive and 2-drive OWC Thunderbolt enclosures which generally work well. However I just got the Mercury Elite Pro Dock. I really don’t like it because the fan is so loud, and I am not sensitive to noise: https://eshop.macsales.com/shop/owc-mercury-elite-pro-dock
I’d personally consider a top-spec 8-core iMac 27. I have a 2017 iMac 27 and a 10-core iMac Pro. The iMP is great, very quiet and has 4 Thunderbolt 3/USB-C and 4 USB-A ports, also 10-gig ethernet.
The regular iMac 27 only has two Thunderbolt 3/USB-C ports and 4 USB-A ports, but with daisy-chained Thunderbolt drives you generally don’t need as many ports.
If you need to replace a bunch of older 4TB drives, several of those will fit on a single 2-drive enclosure with 12TB drives. However the 4-drive enclosures aren’t much more expensive and are a lot faster.
The iMac Pro is very quiet but supposedly the new 8-core iMac 27 is also significantly improved acoustically, just not equal to the iMP.
The regular iMac is a little smoother on some 4k H264 codecs, maybe due to Quick Sync vs the iMP’s T2 chip. However your old Mac Pro has no hardware transcode acceleration whatsoever, so anything would be an improvement over that.
If Apple would just update the iMac Pro that could be a nice option. But even the top-spec regular iMac 27 is much faster than your current machine.
