Hi all, I'm in a bit of an internal debate about whether I should stick a 500GB Samsung 840 EVO into my MacBook Pro (see sig) or whether I should wait and upgrade it in a couple of years. Specifics I use it mainly for audio recording and post-production across several DAWs and mastering suites. I tend to upgrade every five years, so I'm only two away from finishing this system's lifecycle. I don't sell my Macs on: typically, they get passed round the family. The stock 5400rpm 500GB drive doesn't feel slow once it's booted up. I keep my OS X partition (and my Windows 8.1 one) as clutter-free as possible. The new MacBook Pros have PCIe SSDs, which are around twice the speed of the SATA III crop. Whether I'd feel this extra benefit is debatable, but still. I'd also add another 4GB of RAM to bring it's total up to 8GB (may as well, since I'm under the hood anyway). Total cost of the upgrade would be £240. It seems expensive for two-year's use, plus it's about 15% of the cost of a new machine. What would you guys/girls advise?
