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:

CPUIntel Core i5-2500K running at 3.3GHz (Turbo & EIST enabled)
MotherboardASRock Z68 Pro3
ChipsetIntel Z68
Chipset DriversIntel 9.1.1.1015 + Intel RST 10.2
MemoryG.Skill RipjawsX DDR3-1600 4 x 8GB (9-9-9-24)
Video CardPalit GeForce GTX 770 JetStream 2GB GDDR5 (1150MHz core clock; 3505MHz GDDR5 effective)

마찬가지로 850프로에 이어 두번째 높은 성능

 

Desktop Iometer - 4KB Random Read

The models with the new MGX controller enjoy excellent random read performance, although the 1TB version isn't bad either. Without knowing the specifications of the MGX controller, it's hard to know what is causing the performance increase, but I still suspect it is due to a higher clock speed.

4KB 랜덤 읽기/쓰기 성능 : 850프로에 이어 역시 2번째 성능

 

 

Desktop Iometer - 128KB Sequential Read

Sequential performance doesn't present any real surprises. Write speed at smaller capacities gets a small boost, but other than that the performance is typical SATA 6Gbps level.

AS-SSD Incompressible Sequential Read/Write Performance

The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers, but most other controllers are unaffected.
