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 WD Se array averages 645 IOPS in this mixed workload test, while the Red array trails with 555 IOPS at QD256.
The WD Red actually beats out the Se array in the lower-end of the latency chart, with great results in the .6-.8ms and 1-2ms range.
RAID 0 Fileserver
The File Server profile represents typical file server workloads that are very relevant to NAS usage. This profile tests a wide variety of different file sizes simultaneously to simulate multiple users with an 80% read and 20% write distribution.
The WD Red again only trails slightly, with an impressive average of 689 IOPS at QD256, a result that is very close to the 791 IOPS from the WD Se array.
