I thought the wear worries about SSDs were old news. AFAIK newer drives last as long as mechanical
They last at least as long and probably longer.

I'd never buy an SSD, though. They may be reliable in the sense that they don't fail randomly, but they wear out crazily fast(a year, give or take, some friends had there's fail in ~ 9 months). While I haven't lately had a much better track record with physical drives, I can typically get 2-3 years out of them, longer, depending on how many fucks I have to give about the machine it's in(I've actually got some 10+ year old mechanical drives still trucking).
One person's failure within 9 months is pretty far from being representative of the population.
For the past three generations, SSDs in general have been very reliable and very long lived. It's been more than 5 years since reliability was a valid concern for SSDs.
Some brands and product lines within brands are more reliable than others with Intel generally being the most reliable and Intel's server line being the most most reliable. The difference in reliability between the top brands (Intel, Samsung, Crucial, Micron, OCZ, etc.) is small enough to make them substitutable for each other for most applications.
There are web pages that suggest that SSDs won't tolerate frequent and sustained writes "because it'll wear our the electronics", however these articles are written before 2011 or lack any cited sources (that's code for "they're unsubstantiated opinion").
The articles that cite actual testing, objective metrics such as rates of return, or in the case of
TechReport.Com perform actual 18 month long endurance test themselves indicate that SSDs will outlast manufacturers' estimated lifetimes not merely by "significant margins", but by multiples.
Quote:All of the drives surpassed their official endurance specifications by writing hundreds of terabytes without issue. Delivering on the manufacturer-guaranteed write tolerance wouldn't normally be cause for celebration, but the scale makes this achievement important. Most PC users, myself included, write no more than a few terabytes per year. Even 100TB is far more endurance than the typical consumer needs.
I keep my mechanical drives spinning 24x7 throughout their life (server with 18 drives (boot mirror and 2x 8drive raid-5)).
They usually live a bit longer than their 5 year warranties, and I find that when one fails, the others within the same array follow within a year.
If you're only getting 3 years out of your mechanical drives, you might look for environmental influences that are shortening their lives.
If you've for a 10 year old drive "that's still trucking along" you should probably give some serious consideration to moving that machine's task to a VM on contemporary hardware. Abstracting the OS from the hardware will make it much easier to keep the role that machine performs going as hardware continues to evolve.

I went with a 32GB USB3 and copied DDO onto it and have never looked back.
USB3 sticks are cheap and simple. Only caveat is you need a reasonably modern machine with USB3 ports to get this benefit.
USB3 is much faster than USB2, but for DDO USB2 is fast enough to provide a significant improvement over mechanical hard drives because DDO's bottleneck in most cases is random access time, not transfer rate.
Don't deny yourself faster instance changes because you "only have USB2".
