I do graphic designing, prepress & most of the file management at a small (2 owners – 5 employees) print shop. Although its not a huge operation, we're very busy and the iMac that I work on has taken a decent beating over the past few years, and definitely needs an upgrade because the performance of the HDD thats currently being used can be pretty bad at inconveniently random times. I use an SSD with my MacBook at home, and the performance between the two is always noticeable, so we're looking to get a SSD running on the iMac.
My question is, since we will have a lot of file reading/writing, and are constantly running relatively big applications like MS Office and the Adobe Suite, even though I'm intending on setting up a separate external drive for file storage, does anyone have experience with what SSDs perform best both in terms of longevity and speed in a commercial printing environment such as what I mentioned, and which perform best for Macs? We're also trying to keep the cost below $400 or so.
