       | SSDs sacrifice durability of data for io speed

         | that is called the consumer SSD market.

         | You'd at least hope that enterprise SSDs with a Dell sticker on
         | them are better.

         | The article doesn't really support this claim. It argues SSDs
         | sacrifice speed and durability for capacity and cost and then

         | ongoing test to find out.
         | 
         | I do wish the test had more than $13 TLC drives though.

       | This is what I do. I hate doing it, but it's for posterity's
       | sake. I'd be lost without certain data. I have old virtual
       | machine disk images that I've been using for years, ISOs of
       | obscure software, and other rarities. Every 4 years I buy a new
       | 4TB HDD and copy over files to a freshly bought disk.

       | Making more copies, with some geographic distribution, is more
       | important than the durability of any particular technology. This
       | applies to everything from SSDs, HDDs, CDs, to paper, to DNA.
       | 
       | If you want your data to last, replicate it all the time.
