Faster Photoshop Scratch for Memory-Limited Macs with Thunderbolt 2
It’s always better to max-out memory if/when performance is suffering from too-little memory in Photoshop.
But all Macs have limits: 16GB for MacBook Pro and MacMini, 32GB for iMac, 64/128GB for 2013 Mac Pro.
Once memory is maxed-out, the Photoshop scratch disk is the next recourse—it should be as fast as possible. For those with Thunderbolt 2 capable Macs, the new OWC Thunderbay Mini with SSDs fits the bill nicely, beating out even the lightning-fast 1TB SSD in the MacBook Pro Retina.
