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.

I agree, this is the way to go if you happen to have an SSD. SSD for the system, hard drive for data. But I have to admit that I don't trust SSDs for the long term--even when used as a system drive. For example, if you regularly do a fresh install of your OS while keeping your /home directory intact, and you use a distro that has a release cycle of under a year, how many OS installs will you be able to do before bits start to go bad? Never mind the typical package updates throughout the lifespan of a distro; there are usually lots of those.

The fact that these things have to even be considered makes hard drives a more attractive choice in my opinion. Also, if you're a distro hopper you may run into problems sooner. What about swap space... should you put your swap partition on a hard drive, and then suffer the slowdown of using a hard drive anyway (eliminating one of SSD's biggest advantages) as soon you start running out of RAM--all because the SSD cannot be trusted for frequent rewrites?

Do the maths. 3000 p/e cycles per block. So for a 128GB drive with ideal wear levelling, you can write ~3000 * 128GB. If you write 64GB a day (unlikely) you'd get 6000 days worth of writes. That's > 16 years.

My guess is your SSD will outlive your machine, and may well die a related death before the FLASH dies.
