TR FileBench — Real-world copy speeds
FileBench, which was concocted by TR's resident developer Bruno "morphine" Ferreira, runs through a series of file copy operations using Windows 7's xcopy command. Using xcopy produces nearly identical copy speeds to dragging and dropping files using the Windows GUI, so our results should be representative of typical real-world performance. We tested using the following five file sets—note the differences in average file sizes and their compressibility. We evaluated the compressibility of each file set by comparing its size before and after being run through 7-Zip's "ultra" compression scheme.
|Number of files||Average file size||Total size||Compressibility|
The names of most of the file sets are self-explanatory. The Mozilla set is made up of all the files necessary to compile the browser, while the TR set includes years worth of the images, HTML files, and spreadsheets behind my reviews. Those two sets contain much larger numbers of smaller files than the other three. They're also the most amenable to compression.
To get a sense of how aggressively each SSD reclaims flash pages tagged by the TRIM command, the SSDs are tested in a simulated used state after crunching IOMeter's workstation access pattern for 30 minutes. The drives are also tested in a factory fresh state, right after a secure erase, to see if there is any discrepancy between the two states. There wasn't much of one with the Premier SP610, so we're only presenting the used-state scores.
Well, well. Despite its controller-level handicap, the SP610 copies the files in our TR test faster than all the other SSDs. It ties for the highest copy speed with the similarly small files in the Mozilla test, too, but the SP610 isn't as competitive in the movie, RAW, and MP3 tests. Those tests involve much larger files—and much higher speeds overall.
If I were to lazily lean on another automotive analogy, I might suggest that the SP610 is faster in the corners, as it darts from small file to small file, than it is on the straights, where its top speed isn't high enough to keep up with larger, lengthier transfers. But I'd never stoop to such tactics to spice up an otherwise dull subject.
