Results: Enterprise Workload Performance
Our next set of tests simulates different enterprise-oriented workloads, including database, file server, Web server, and workstation configurations.
Notice that the results are pretty similar, regardless of whether you're looking at the 200 or 800 GB model. This is the case largely because high-end workloads are generally biased to read operations. Both capacities offer the same read performance, so it's no surprise to see them so close to each other.
At lower queue depths, the 800 GB SSD DC S3700 is consistently faster in each workload. It also exhibits an advantage in the file server workload. However, if your application mostly involves read operations, any of Intel's available capacities should be suitable. Our only warning would be that the 100 GB drive, which we don't have in-house, is rated for significantly lower write performance.
Our database workload (also categorized as transaction processing) involves purely random I/O. Its profile consists of 67% reads and 33% writes using 8 KB transfers.
The file server workload consists of 80% random reads of varying transfer sizes.
The Web server (100% read, varying transfer size) and workstation (80% reads, 80% random) workloads show the same basic trend.
but it's wonderful when you can have all four.
Kudos to Intel for raising the bar yet again on SSD quality. Eagerly awaiting trickle-down effect.
For 2.5" HDDs, you have ~1W idle and 2-2.5W seek/spin-up.
I'm a little surprised at how much power Intel's enterprise SSDs are using. I'm guessing a good chunk of the reason comes from having extra circuitry to do the double-conversion from 5/12V to ~30V and then back down to whatever the SSD needs.
You nailed it. If you look at 2.5" 15K and 10K RPM drive, the Intel is better on W/GB, but it is pretty high when compared to other SSDs.
i am not sure if watt/GB is important for storage.
Reason : the new philosophy is to "hurry up, finish the work, and relax".
