128K Sequential Performance
The 128K sequential speeds reflect the maximum sequential throughput of the HDD using a file size encountered in normal usage.
The Toshiba 8-drive and 4-drive RAID 0 arrays average 1,144 MB/s and 526 MB/s of sequential read speed, respectively. The 8-drive and 4-drive RAID 5 arrays provide 1,115 MB/s and 583 MB/s, respectively.
The maximum sequential write speeds topped out at 1,144 MB/s and 474 MB/s for RAID 0, and 1,094 MB/s and 575 MB/s for RAID 5.
RAID 0 Database/OLTP
This test emulates Database and On-Line Transaction Processing (OLTP) workloads. OLTP is in essence the processing of transactions such as credit cards and high frequency trading in the financial sector. Databases are the bread and butter of many deployments. These are demanding 8K random workloads with a 66% read and 33% write distribution that can bring even the highest performing solutions down to earth.
The eight-drive RAID 0 array leads the way with 1,509 IOPS, and the four-drive RAID 0 array trails with 808 IOPS. The RAID 5 arrays deliver 748 IOPS and 392 IOPS, respectively.
