Performance - USB 3.0 and SATA3 6G storage performance
USB 3.0 and SATA3 6G storage performance
So here's where I will get a little lazy charts wise. With the new SATA3 6G controller and USB 3.0 controllers we started adding SSD performance numbers measured on such interfaces (when applicable). Putting these in nicely styled charts would be better, but with technology so new we just do not have anything out there yet to compare to, so here are some RAW numbers:
USB 3.0 performance Read MB/sec Write MB/secMSI 890GX | X4 965 132 108GA-890G | X6 1090T 173 144ASUS Maximus II Ex | 870 178 134ASUS C4F 890FX | X6 1095T 181 156ASUS 890GX |X4 965 195 175ASUS R III Ex | 980X 200 155Above you can see a N002 series A-DATA SSD running over its the USB 3.0 interface on the motherboard. As you can see, the implementation works out really well. Nearing 175 MB/sec read and 144 MB/sec write performance. A little below the competition, but nothing worrysome.
| SATA6G AHCI | Read MB/sec | Write MB/sec |
| ASUS C4F 890FX | X6 1095T | 261 | 159 |
| ASUS 890GX |X4 965 | 265 | 176 |
| ECS H55H-I Core i5 661 | 265 | 184 |
| ECS A890GXM-A |X4 965 | 266 | 174 |
| MSI 890GX | X4 965 | 267 | 178 |
| ASUS R III Ex | 980X | 271 | 180 |
| GA-890G | X6 1090T | 272 | 178 |
Now here we connected the same SSD towards the SATA3 (6Gbit). In the BIOS we now choose AHCI. A small note is in order here, AHCI mode is a little faster for SSDs opposed to HDDs. As you can see that performance is definitely stunning, look at the read speeds there ... roughly 270 MB/sec (!).
However on the other end of the spectrum we see a drop in performance at the smaller files. Intel definitely is be faster in AHCI mode with small file sizes. Alternatively we recommend you simply use SATA mode in the BIOS and leave AHCI for what it is. Right, let's go check out some games and their performance.
