Buy good brands like Samsung and Intel and start using the thing. People seem to think they are fragile but I've found that the above two name brands are anything but.
"A poor man can't afford a cheap suit."
So far, I have adhered to that recommendation: you can't afford to spend your money on crap.
We're also looking at M.2 and PCI-express SSDs, using bandwidth from the PCI-E bus. Not entirely very cheap at the moment.
I just took a chance on an ADATA SP550, and would've looked again at Samsung or Crucial but for the ADATA specs and other features. Taken with a grain of salt to be sure, the Egg customer reviews seemed encouraging. 480GB for about $110. No problems yet; the drive has been in the system for a couple months now. And that's about 25% of what I'd spent on a 500GB 840-Pro in early 2014.
And . . so far . . . it shows about 1.4TB of accumulated writes. Since this includes the cloning of a Win 7 OS and the installation of a Win 10 on a separate partition, and since the last time I looked at it two weeks ago when it was about 1.29TB, I could be writing more than 200GB/month. Suppose it's really double that; suppose I'm writing 5TB per annum. The drive will still be pre-adolescent after 5 years.
