I finally got the SSD for my Macbook Pro I've been hankering after for a long time now. It's fantastic, just like everyone said it would be.
Should you upgrade your current machine with an SSD? Probably. Should you make sure there's an SSD in your next machine? Definitely.
Here's the interesting thing though - it doesn't feel fast any more, and I've only had it for a bit over a month. So what's happened? Something must have gone wrong technically. Maybe it needs to be sent back and replaced with a new, fast again drive? Nup. The drive is still working perfectly. It's just that crazy fast is the new normal. Which means if I ever switched back to a regular spinning disk, it would be painfully slow. The only thing that has changed is my perception of it.
In many ways, it's a great problem to have. My machine is now fast enough that I don't notice it's limitations in my current use cases - most notably creating and running lots of virtual machines concurrently.
Other upgrades that had a similar effect include putting 16GB of RAM in the MBP and the retina display on the newer model iPhones and iPads. Once you've used them for a short period of time, you really only notice when they're not there any more.
Ultimately, this is how technology should be. So adequately specced that it doesn't draw attention to itself. Once those technological limits are out of the way, the technology fades into the background and you can get on with the important work you have to do. The technology serves you, it's a lever for your creativity, and it doesn't break you out of your flow with painfully slow file transfers and memory limits.
Here's a speed test (5GB data transfers) for the original 5400RPM disk Apple shipped.
And here's the Samsung 830 SSD.
In the context of "fast enough", the numbers barely matter. It's fast enough, for now.
