In our large SSD Roundup was the Crucial RealSSD C300 get hold of thanks to the excellent performance of the award for Best Hard Goods Product, the main incentive of RAID 0 is due to significantly increase transfer rates. In simplified terms, the amount of data on both disks involved is divided thus, read and write requests can be made on both drives in parallel, depending on the situation, should theoretically almost double the data throughput possible.


The mainboard of our new test system is equipped with AMD 870 chipset, thanks to the South Bridge 850 has six ports with native SATA 6 Gbit / s. This already is a possible bottleneck and prevent all STDs can be operated at their maximum capacity, also with regard to future SSDs the speed interface is useful.


For all the time of testing SSDs latest firmware is used, Crucial SSDs are operated both on-board RAID controller, it is given to the driver from AMD (ahcix64s.sys), version 3.1.1540.151 for use and the chunk size was defined to 64 Kbytes.

In Crystal Disk Mark is similar to the AS SSD benchmark is a synthetic tool, for the tests, a 1000 MB file is written to the hard disk or read. This is done for a sequential, random based on the other with 512 KByte and 4 KByte data blocks, the 4K-QD32-test is working with 32 concurrent requests.


All results of the AS SSD benchmarks are confirmed in this benchmark, the sequential transfer rates and 512K benefit greatly from RAID 0 In the 4K tests a slight Steigerung is recognizable. The anomalies in the simultaneous reading of 4K files can also be observed here, with the concurrent writing of 32 4K files the performance increases by 51 percent.


It is always on the intended use, the sequential transfer rates will benefit enormously from the merger of the two Crucial SSDs, this extra capacity is especially noticeable when copying large amounts of data, for everyday work can be felt but little of the increased performance. Applications run only slightly faster than with a single SSD and the antivirus benchmark shows an acceleration in the low single-digit percentage range, the boot process of Windows 7 by the RAID 0 even held back normal.
