Hi everyone, I'm in the market for a new 27" iMac to replace my 2011 model for work and I'm somewhat torn between getting an SSD for applications and using my 1TB external USB drive for files or just getting the 1TB Fusion drive. I do web design and development so I have quite a lot of files from clients sitting on my machine so I'm going to mostly be spending my time using PHPStorm (a PHP IDE for website development) with either MAMP or Vagrant and Photoshop and Lightroom for managing client photos etc. Does anyone have experience in both drives? I've read reviews saying that the SSD cache on the Fusion drive isn't as big as it used to be (24Gb now)? I'm not sure we can spring for the 512Gb SSD so I think we would be on the 256Gb model if that would be a factor. Any thoughts / opinions would be greatly appreciated.
