have had a few intel 730 ssd's for few years, since 2014 when it was released and used them a ton. I think hours on them , last time I checked , were around 21,000 each , and still rated at 100% health. I believe these ssd's are good for millions of hours and they had a 5 year warranty. To be honest though, I think crucial, intel, Samsung, adata, and WD are all good companies to buy ssd's from. Did have problems with Sandisk, multiple times, and do not recommend that brand. They are just a crappy ssd with slow speeds as soon they get a little hot.
