Performance highlights — continued

FileBench
FileBench looks at copy speeds using real-world files. Most of the file sets are self-explanatory: movies, RAW images, and MP3s. The TR set includes the image, HTML, and spreadsheet files that make up typical TR content, while the Mozilla set comprises all the files needed to compile the open-source browser. Click on the buttons below the graph to see the results for each set.


The Premier Pro performs reasonably well here. It's not the fastest SSD in the bunch, but its copy speeds are competitive across all file types.

Once again, the Crucial M550 512GB sticks close. Although the gaps between the two are slightly wider in some of the tests, that's more due to the fact that FileBench has greater run-to-run variance than our other benchmarks.

IOMeter
IOMeter highlights performance under a scaling load that increases the number of concurrent I/O requests. Desktop systems rarely deal with more than a few simultaneous requests, but the command queue associated with the Serial ATA spec supports up to 32. Ramping up the number of requests gives us a sense of how the Premier Pro 920 might perform in more demanding enterprise environments.

The SP920 and M550 512GB are right on top of each other. Neither is competitive with the best SSDs in this test, but they both hit higher I/O rates than all of the Samsung drives, at least for the lighter loads that are typical of desktop systems. The SP920 wasn't designed for demanding enterprise loads.

Power consumption
We tested power consumption under load with IOMeter's workstation access pattern chewing through 32 concurrent I/O requests. Idle power consumption was probed one minute after processing Windows 7's idle tasks on an empty desktop.

Another test, another set of nearly identical results for the brothers from different mothers. The Premier Pro is pretty power-efficient overall, making it well-suited to notebooks. The differences in power consumption aren't big enough to matter in a desktop system, though. They might not even make a meaningful difference in pint-sized systems like the Intel NUC and Gigabyte Brix Pro.
