I agree that both would probably work for two years. The big difference between enterprise SSDs and consumer one is write endurance. If you are using this for let's say an embedded web server, the number of writes to the SSD will be minimal and there wouldn't be much difference in terms of reliability between the two classes of drives. If you are building something to log data, you may want to consider an enterprise class SSD.

Probably both. Note: consumer grade 2.5" hard drives (meant for laptops), *might* not be as long term reliable as enterprise grade 2.5" hard drives (meant for servers). The SSD will be faster than the rotating rust drive. > > (Note: I am looking at this Kingston 240GB ssdNOW 300 that I pulled > from a notebook that had to be upgraded to a 480GB SSD) > > thanks > > _______________________________________________ > Arm-dev mailing list > Arm-dev at centos.org > https://lists.centos.org/mailman/listinfo/arm-dev > > -- Robert Heller -- 978-544-6933 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services heller at deepsoft.com -- Webhosting Services _______________________________________________ Arm-dev mailing list Arm-dev at centos.org https://lists.centos.org/mailman/listinfo/arm-dev
