ATTO DISK Benchmark over 64k test, the max reading is 152 MB/s and writing is 158 MB/s
CrystalDiskMark reading is 152.4 Mb/s and writing is 156.4 MB/s
FDEBENCH reading is 148 Mb/s and writing is 123 MB/s

USB 3.0 bandwidth break away from the limitation, 30~35 MB/s speed of USB2.0.
For users who using 2.5 or 3.5 inch external HDD box, they can get much higher speed acceleration.
Precondition is waiting for USB3.0 products become more popular, more users can enjoy the high performance from new technology.

As H55 doesnít support RAID, I changed to use single SDD to test transfer rate.
CORSAIR CMFSSD-128GBG2D official spec is 220/180 MB/s

ATTO DISK Benchmark over 64k test, the max reading is 234 MB/s and writing is 188 MB/s
CrystalDiskMark reading is 220.4 Mb/s and writing is 178.2 MB/s
FDEBENCH reading is 214 Mb/s and writing is 182 MB/s

CORSAIR top SSD performance is extremely high. Even it is MLC, the performance is close to SLC.
Back to H55 chip, the HDD transfer ability is around 3% lower than X58/P55. Itís acceptable range.

OC Performance
CPU 200 X 23 => 4600MHz
DRAM DDR3 8GB 1600 CL9 9-9-24 1T
GPU 9600GT 512MB

Hyper 4 X PI 32M=> 13m 54.305s
CPUMARK 99=> 708

Nuclearus Multi Core => 17951
Fritz Chess Benchmark => 17.35/8331

CrystalMark 2004R3 => 215783

1 CPU=> 6289
x CPU=> 14639

PCMark Vantage => 16604

32nm manufacturing can make dual core CPU clock be OC to higher.
This Core i5-660 quality is not better than 661. It needs 1.360V to reach 4.6GHz.
Of course, if you use original Cooler to OC, you need higher voltage to ramp up the speed.

Rising up the CPU voltage to achieve 5GHz in air cooling.
CPUZ official certificate.
Intel Core i5 660 OC 5G / windwithme

Last is power consumption in OC condition.
CPUZ shows 4500MHz and IGP built-in VGA.
Standby - 73W

Full speed - 135W
CPUZ shows 4500MHz and 2 physical cores + 2 HT virtual cores utilize status.

CPUZ shows 4600MHz and 9600GT
Standby - 107W
