- jacquesm 10y agoFor now. Making unqualified statements about the future is where the problem lies. In the long run, silicon will win over spinning rust and 'the long run' seems to be a lot shorter than we previously thought.
- vidarh 10y agoDisks are more expensive for most server use today than SSDs. You can't just look at cost per GB. You need to look at cost to process per GB, and then the vastly increased IOPS and transfer rates provided by SSDs makes them cheaper for most applications where data is regularly accessed at this point. There are niches, such as long term archival, backups, etc. where disks may still be competitive, but even those are rapidly being eroded. For things like web servers or database servers, I'll never provision another machine without SSDs.
