Use CrystalDiskMark8 to test the performance of the ramdisk
Basic Tab:
Size:512MB
Allocate Memory Dynamically: uncheck
File System: NTFS
Advanced Tab:
Cluster Size: Default
Quick Format: uncheck
Enable NTFS Compression: uncheck
Use Mount Point: uncheck
Additional Parameters: empty
if check the "Use AWE physical memory" option, will get a very slow 4k read/write speed
SEQ1M(Q8T1): Read 5208MB/s Write 6435MB/s
RND1M(Q8T8): Read 16527MB/s Write 30410MB/s
RND4K(Q32T1): Read 233MB/s Write 222MB/s
RND4K(Q1T1): Read 232MB/s Write 224MB/s
if not check the option, can get a good performance:
SEQ1M(Q8T1): Read 6153MB/s Write 7360MB/s
RND1M(Q8T8): Read 6034MB/s Write 9123MB/s
RND4K(Q32T1): Read 1307MB/s Write 1061MB/s
RND4K(Q1T1): Read 886MB/s Write 785MB/s
I have used three pc to test, all of them got the similar results, is this a problem?
