Still, the little-2500K-that-could was maxed out, and it’s bigger brothers could probably reach nearly one-million IOPS. Not bad for a few minutes of tweaking and overclocking. One last run of 4K random reads at a QD of 4 yielded the highest numbers yet - 765137.3 IOPS. There are many facets and possibilities with FC, and the surface has only yet been scratched. As such, it’s not yet for sale but freely available to test.
#FANCYCACHE TEST SOFTWARE#
Romex Software is currently beta testing Fanc圜ache. In the best case scenario, almost all accesses occur directly from the RAM, and performance skyrockets. Fanc圜ache is easy to set up, and much more convenient that traditional RAM drives.Ĭaveats aside, the worst case scenario when using FC with a SSD is that performance will only be as fast as the SSD. If an application is heavily dependent on storage performance, RAM caching can yield incredible performance increases over SSDs alone, much less traditional spinning media. In specific applications, the performance increase could pay serious dividends. Using ECC RAM where possible could help in this respect, but it is seldom seen in most enthusiast systems. More importantly, the risk of data loss is omnipresent - if FC is caching writes to RAM, any fault with the RAM or sudden system crash could result in lost or corrupted data. When the system turns off, the cache disappears. First, since RAM is volatile, the cache is not persistent. Low and high QD randoms, sequential, access times, and IOPS are all marvelous when operating out of the cache.īut there are some caveats. Further, getting more performance when overclocked is just more icing on a hellaciously-fast cake. Intel’s X79 motherboard and Sandy Bridge – E processors could very well crush these mainstream components.Īll things considered, the IO performance and huge throughput that RAM provides when acting as cache for a SSD is a wonder to behold. The midrange components used here are fast, but still outclassed by much faster systems. These are fairy tale numbers, and just the beginning of what could be possible with such an arrangement on a faster system. Each scoring component is moving at least 1700MB/s. Without caching, the distressed Mushkin Chronos Deluxe could only manage a score of 52877. The HDD component of Vantage puts in one of the highest scores around at 622865 points. Now that the upper performance limit has been reached, perhaps a more real-world relevant test would show what this level of performance can achieve.
