There couldn’t be a better time than the present to purchase an SSD, and on the same token, it’s also a strange time. Performance drives cost the same as budget drives, and a perfect example of this is Corsair’s Force F90. It’s priced-right, offers incredible performance, and makes perfect use of its SandForce SF-1200 controller.
HD Tune has long been one of our favorite storage benchmarks, thanks in part to its ease-of-use, and its ability to deliver consistent results (which is obviously important). Since we are using HD Tune on storage devices that also house our OS, we’re unable to test the write performance, so here, we stick to both Read and Access Times.
The Corsair Force 90GB puts up more good results in the HD Tune program, although the larger capacity Vertex 2 gains a slight edge. It is good to see that despite a one-fourth reduction in capacity, that drive performance isn’t appreciably changed.
Again we show the access times as these are the hallmark of solid-state drives, which can’t be underscored enough. Three milliseconds to read a 1MB file sounds like a long time by SSD standards, but in actuality it is the quickest time here. The lone mechanical drive requires ten times as long to access the same size file by comparison. Bandwidth isn’t just a flat value, it is determined by the type as well as the size of the file operation that is utilized for the comparison.
HD Tach is a program similar to HD Tune, and although it hasn’t been updated in a few years, it’s still decent for testing SSDs. It offers a different method for calculating burst rates, as well as offering access time measurements below 0.1ms, which is unfortunately the limit for HD Tune. With a massive new program rewrite in the works, we look forward to seeing what the upcoming new version can do.
HD Tach is unfortunately showing its age as it is the only program that isn’t updated to natively support Windows 7 or Vista. A complete rewrite of the program was announced, but until then we will toss numbers in from this one to contrast with HD Tune. The 90GB Force didn’t fare well in this program, but again neither did drives like the Revo so we won’t read into this one.
