No I didn't think you were lying to me, I just wondered if you just assumed it, rather than knew, no offence intended as you never know on forums! But I appreciate your expertise.
Well I say only use photoshop, I obviously use a browser as well - chrome -which uses tons of memory. I make websites, so a program I use for that takes up about 800mb.
So in your opinion then, is getting an ssd going to speed up the speed in which photoshop responds? I am so tempted to buy a new macbook but I really don't think I can afford it and I'm not sure whether I need it, it's just my inner 'i-want-a-new-macbook' talking.
And that was my attempt at some dry humour! I'd never call myself an expert when it comes to hardware, but I've done my fair share of research since wanting to upgrade my current setup (top-end 2010 iMac + top-end 2009 MacBook both now with SSDs inside) about 6 months ago. I'm waiting for the next refresh.
The SSD in my MBP really did help me at the time. I was writing a very hefty document and doing some Java programming (Android, shock-horror!). For those tasks, the SSD was enough to add some speed and cut out some spinning wheels. However, since finishing that document and moving back to normal life - also web development until recently - I've realised that the SSD isn't "just like a new Mac" as many might suggest. My MBP gets hot when running my iMac screen from it, and absolutely hates running Photoshop to any real extent. The graphics card struggles, the processor struggles. It's quite simply
old, and running 4 years ahead of its time.
I can't give you a definitive answer to your question of whether you should buy a new Mac or an SSD, because it's subjective. All I can tell you is that an SSD will
only improve read/write speeds. You will
notice improvements doing the following (related to web design/dev):
- Booting your MacBook will be extremely fast
- Opening your apps will become almost instantaneous - even Photoshop, etc.
- Saving and opening large Photoshop files will be faster
- If you're working on very large Photoshop files, then it may improve performance (we're talking much bigger than a website PSD) since PS resorts to using your hard drive as a scratch disk when you run out of allocating memory (more info)
- Saving or opening large video files will be faster
- Any other large read/write operations will be vastly sped up
With a new Mac, you will get all of that (assuming you get an SSD of course), but with the overall improved performance of Photoshop, and other resource intensive programs due to improved processor/graphics/memory performance. Obvious, I know - but perhaps me putting it this plainly will help you decide.
Out of interest, have you tried a fresh install of OS X to see if that helps? After reading your first post again, your symptoms do seem a little extreme given the hardware you're on. I would seriously make a backup ASAP in-case your hardrive is on its way out.
