Asus PCIe GEN2 SATA6G expansion card

HDTach RW & HDTune Pro

HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives (ZIP/JAZZ), flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device possible. The benchmark was run with the drive in a clean, unformatted state. The results can be seen below run on the ICH10R controller first then with the Asus 6G controller:

HDTune Pro
HD Tune Pro is a complete hard disk benchmarking, status and erasing utility by EFD Software. Capable of benchmarking performance across 100% of the disk HDTune is especially useful for mechanical hard drives that have greater performance towards the centre of the platter. As SSD drives do not suffer from any noticeable performance degradation across the entire capacity of the disk, this makes HD Tune an excellent utility for displaying the differences in performance between the two types of media. Our testing procedure involved running both the read and write benchmark tests on each of the drives with screen shots of the results being taken at the end of each benchmark run. The benchmark was run with the drive in a clean, unformatted state.The results can be seen below:

Results Analysis
Both HDtune Pro and HDTach RW showed improvements were to be had using there expansion card. However, the results were not that significant, boosting the speed of the ICH10R controller by a little over 10MB/s in all the tests run evening out at around 9% improvment by using the Asus 6G controller. What IS significant is the burst rate which increases by a fair margin in both read and write tests with improvements that double in HDTach RW and increase by over 50% in HDtune pro. Burst speed gives an indication of the controllers speed and as the above results show, the Asus PCIe GEN2 SATA6G controller performs admirably in this department. In todays market, storage space is still held high on the list and perhaps the biggest reason why SSD's are still not as popular as mechanical hard disks so this leap in burst speed will no doubt be greeted with open arms by those looking for a large storage solution AND speed.
Let's see what our other benchmarks make of the expansion card...

Be nice to see if this affected Crossfire or SLI performance as the Gigabyte solution does.

Good review as usual though Rich Quote

It all depends on how many slots you have available. With P55 having 16 lanes available, taking 4 up with the SATA6 card will have some effect on SLI performance, if indeed you have a spare slot to begin with on P55. X58 however has more lanes so SLI/xfire performance will not be affected unless you intend on running 2x dual GPU cards that require the full 16 lanes or indeed triSLI/crossfireX.Quote

Amazes me that the population on a close up look is for USB. The parts are ofc missing.

I did think, looking at another manufacturer, that the un-soldered bits were for eSATA of sorts. Apparently not.

Nice review.

Not a bad price tbh. Online stores may massage that a little. Wouldn't be too suprized if a fully populated version comes out afterwards. They're *******s for doing that. Bring out the lesser - get u to buy it - then out comes the trump card.Quote

Great idea for those on older tech but still want the speed. Once some drives come out at a decent price, or I pick up a 6G capable SSD I may grab this too Quote

I'd be interested to see this card with a RAID setup of SSD's.Quote
