Are there any measures of the >impact on wear? Hi, I wonder why I need to read on all computer related mailing list the same questions related to SSDs again and again. For what do we get HDDs or SSDs? We get them for using them. However, there is a very clear answer to your question. Keep the SSD in the original packaging, never use it, this does reduce wear a lot. However, if you decide to use it for read and write operations, you can handle it in the same way as you handle a HDD, just use the trim command from time to time. SSDs don't break after a year, if you use them. They last for years. Non of mine ever failed. Probably SSDs suffer from less wear than HDDs do, time will show us. I'm using HDDs only for backups and to archive data. Handles, light switches, everything wears out. This is the nature of everyday objects, but all those things last for a reasonable time, if you use them. SSDs aren't cheap USB sticks, they are made for modern computers that write and read way more data, than computers did a few years back. Swap is probably never used, but software sizes, picture and video sizes, and other data sizes, professional and home used data increased a lot. What exactly makes you think, that SSDs need gentle treatment? Regards, Ralf
