I just built a RAID0 array using four (4) Samsung 940 Pro 256GB SSD drives and an LSI MegaRaid SAS 9240-4i RAID controller. Firmware on all drives was updated to DXM04B0Q. Firware on LSI card was updated to latest (2.130.364-1847). Array stripe size is set to 64KB (largest available) and all settings in LSI volume setup wizard were left at defaults. Drive was formatted regularly under Windows 7x64. The card is in a PCIeX16 slot.
CrystalDiskMark results are as follows:
Is this normal? It seems to fall a bit short of my calculations for the potential of this setup. I know this is still fast, but not as fast as it should be I'm afraid. I need at the very least 1.5GB/s for heavy I/O video / audio work. What do you think the bottleneck here is? Any thoughts / tips on setup?
Thanks
