4TB raid 0 (4x1TB) on LSI 1068E gets ...... 14 MB/s read???
My 4 disk raid is far slower than I expected
measured using: # hdparm -tT /dev/sdb1
Timing cached reads: 32356 MB in 2.00 seconds = 16211.66 MB/sec
Timing buffered disk reads: 44 MB in 3.04 seconds = 14.46 MB/sec
2x xeon x5680
48 GB ram
integrated LSI 1068E controller (recognized for some reason as MegaRAID SAS 8208ELP/8208ELP, which is an add-in card similar in functionality to the integrated controller)
1x samsung spinpoint 1TB (system)
4x samsung spinpoint 1TB RAID 0 (workspace) formatted as ext3, single partition
The system seems to recognize the 4TB raid fine, its just slow. any ideas?
