Thunderbolt SSD as a scratch disk in CS6

What kind of speed increase am I likely to see as opposed to just having my scratch disk on the home drive?

New iMac also comes with a fusion drive, which I assume will speed things up dramatically as well. Will adding a thunderbolt SSD as a scratch disk further increase speed?

Thanks
 
You probably will be if you're browsing back and fore Neil. Have to say, I'd be interested in the outcome. TB is a technology I've not used, but I'm interested if it's as good as it's supposedly claimed to be (actual throughput and latency issues included). The big area Macs lack on is data I/O as they have no backplane to plug anything into.........

even with a large chunk of ram?

i like the idea of PCI breakout via thunderbolt.

i get the reasons why but its just a pain that its so hard to get without having to fit a motherboard with it onboard.

It depends... I'm not sure how much LR keeps in memory or the system keeps in cache. If you're generally browsing up and down the catalogue, at some point it's going to have to access the disk... There's always more disk than RAM!

Have to say that it looks to be a very, very expensive way of adding high speed peripherals. Without going down the whole Apple debate, it costs as much as buying a new PC to add single PCI-e expansion via Thunderbolt at the moment. I know it will get cheaper but.........
 
I have 32gb of ram.

When I had 16gb on my old iMac, it used to fill pretty quickly. A lot of my shots are 50+ layers and have to be saved as PSB files. Some composites go as large as 100 layers. That's in 16 bit, too.

It gets to the point where CS6 becomes so slow, I have to save my work and shut PS down and restart in order to get it back up to speed again.

REALLY hoping this will solve at least part of the issue.
 
Ahh... PS... Yes, that's going to use as much RAM as you can throw at it if you're getting that complex.... Sorry, I was thinking Lightroom which is more conservative with memory.
 
so what do you reckon, Andy? Good idea? It's about £160 for a 120gb disk, so not staggeringly expensive, but I'd avoid it if the boost I'd see is only marginal.

What is it attaching to (and what else does the machine have disk wise)?

If I read it right, the fusion drive has 128GB of SSD. If so, I don't think it's going to be a big speed adder to be honest. You have 32G + 128G there anyway, managed by the OS.

Personally, I'd wait and see if the speeds were "intolerable" (they won't be with that spec..) ;)
