I would like to hear your thoughts on this particular SSD. It's going for $170 on Amazon right now and I have a $150 gift card, making this a steal for me. I know it uses TLC flash vs MLC flash, but is there really any huge difference? My iMac only has SATA II and I know the 830 is only marginally faster than the 840, so do you think I would actually notice a difference? I'll probably be selling my iMac next year anyways, thus the longevity of the SSD isn't crucial to me. Let me know your thoughts and opinions and happy Thanksgiving to everyone!
