A good SSD has a transfer speed is around 10x the one on a magnet plate drive, and search time is in nanoseconds, instead of milliseconds. They make no noise, and use very little power.
Difference really depends on what you do. But everything from near instant start up time of applications to super fast compression comes in handy. It feels like a new computer.
Great, thanks for all the info! I think I'll go ahead with the purchase, then use it as an external drive when I get a new computer.
Using it as an external drive, would I get the speed performance that you'd get from using it as an internal drive? If that makes sense... or would I need a Thunderbolt enclosure or something of the kind?
It looks like I can get either an Intel or an OCZ drive for reasonably cheap. As my next computer will most likely be an iMac, would I be able to put to use that FireWire 800 with the SSD?
For OCZ the only model I can recommend is the Vertex 4.
If its a new iMac Thunderbolt or USB 3.0 would be the way to go, new Ivybridge models should be available later this year according to the rumours but current models a Firewire or Thunderbolt enclosure would work fine.
If it's external, then the only limitation would be the transfer rate of the connector cable you are using. I'd recommend usb3, but that means the SSD must have a usb3 port and your computer must also have a usb3 card to take full advantage, otherwise it will be limited to 2.0 speeds. It will be faster than an external HDD because there's no time spent spooling up a disk, but it probably won't be to the SSDs full potential.
There's an appreciable difference, program load times, boot times, and programs that need to read data from the hard drive often or large amounts of data. General usage doesn't its not as noticeable but it will feel snappier overall.
Has anyone with an SSD installed on their computer noticed a dramatic increase? Would you say it's worth the fairly high price?
