Test Systems
For AnandTech Storage Benches, performance consistency, random and sequential performance, performance vs transfer size and load power consumption we use the following system:
| CPU | Intel Core i5-2500K running at 3.3GHz (Turbo & EIST enabled) |
| Motherboard | AsRock Z68 Pro3 |
| Chipset | Intel Z68 |
| Chipset Drivers | Intel 9.1.1.1015 + Intel RST 10.2 |
| Memory | G.Skill RipjawsX DDR3-1600 4 x 8GB (9-9-9-24) |
| Video Card | Palit GeForce GTX 770 JetStream 2GB GDDR5 (1150MHz core clock; 3505MHz GDDR5 effective) |
| Video Drivers | NVIDIA GeForce 332.21 WHQL |
| Desktop Resolution | 1920 x 1080 |
| OS | Windows 7 x64 |
Due to the lower over-provisioning, the X300s ends up being slightly slower than the Extreme Pro and Extreme II. Still, the X300s is a solid performer and faster than e.g. Intel's SSD Pro 2500, which is Intel's offering to the business market. Ultimately the 850 Pro is the fastest SED on the market but the X300s provides a more complete set of features with the inclusion of Wave's EMBASSY Security Control.
The X300s does not perform that well in our 2011 Storage Benches. I would say that the 2011 Benches, especially the Light suite, are closer to a typical corporate workload with lots of email and office use, so I would give more value to that instead of the 2013 Bench. The X300s is still okay in both 2011 Benches and better than the Intel SSD Pro 2500, but I was expecting a bit more given the performance of the Extreme Pro and Extreme II.
Sequential read performance is excellent and sequential write is okay too, making the X300s equivalent to the Extreme Pro.
