Toshiba MK01GRRB/R 2.5-inch 6Gb/s SAS 15K RPM Enterprise RAID Report

By: Paul Alcorn | RAID/HBA in IT/Datacenter | Posted: Mar 15, 2013 1:49 pm

128K Sequential Read/Write




The 128K sequential speeds reflect the maximum sequential throughput of the SSD using a realistic file size actually encountered in an enterprise scenario. One area that HDDs continue to provide performance that is competitive with SSDs is with sequential access.


The RAID 5 provides relatively consistent high read speed across the gamut of queue depths. The 8-drive array averages 454MB/s at QD256, the 5 drives provide 280MB/s and the 3 drives score 119MB/s.




The write speeds exhibit more variability, which is likely partially due to the RAID code overhead. RAID incurs serious penalties in write performance, and here we can observe it significantly affecting the speed of the HDDs.


The 8-drive array provides 81MB/s at QD256, the 5-drive array provides 68MB/s, and the 3-drive array averages 50MB/s.
