Apple I bought a brand new iMac on Tuesday. I'm pretty sure this will come as a surprise to some, so I figured I might as well offer some background information about this choice - maybe it'll help other people who are also pondering what to buy as their next computer.

But I have to admit that I don't trust SSDs for the long term--even when used as a system drive.

A regular consumer-oriented SSD should last around 10 years as a system drive just fine, even with swap on it. There are several websites about this, including specific burn-in benchmarks that just keep reading/writing the SSD until it goes bust.

Modern computers and hard drives are so damn fast anyway, I honestly can't imagine an SSD being that big of an improvement over a good quality hard drive

The difference is like a night and day. SSDs especially excel at reading small files and/or fragments that are scattered all over the disk because of the miniscule seek times. Out of curiosity I tested my regular HDDs the other day and got 7ms and 9ms seek times whereas a USB 3.0 stick got 0.05ms seek times. That's 140 times faster. And guess what? Typical OS-files and program libraries and binaries tend to be small files, scattered all over the place.

Regular HDDs are still good for sequential data, but even there SSDs these days trump HDDs in speeds, with some going up to 500MB/s sustained sequential write speeds.
