- wmf 15y agoSSDs are actually cheaper per IOPS. Considering that everything we knew about hard disk reliability was shown to be wrong (by Google), I wouldn't be surprised if the same holds for SSDs.
- sliverstorm 15y agoIt's hard to see SSD's being a clear win on the surface. It would be very interesting though to see if the cost begins to change when you consider power savings (much smaller than hoped, but they do exist), figure out how much they'd save on HVAC in the datacenters, etc.
- wmf 15y agoHaving worked on power-aware hybrid storage for the last two years, the power savings per GB is pretty much zero; there is significant W/IOPS savings but that still doesn't pay for the capital cost. Performance is really the reason to use SSDs.
- sliverstorm 15y agoper GB is an excellent point, I had not considered that.
- chrisbolt 15y agoHaving installed almost 200 Intel SSDs into servers with 0 failures, I doubt his anecdotal evidence. Also compare with Intel's reported annual failure rates: http://www.anandtech.com/show/4244/intel-ssd-320-review http://www.anandtech.com/show/4244/intel-ssd-320-review and a french retailer: http://www.anandtech.com/show/4202/the-intel-ssd-510-review/3 http://www.anandtech.com/show/4202/the-intel-ssd-510-review/...
