NAS HDD Showdown: WD Red vs. Seagate NAS - Benchmarks - Multi-Client Test

NAS HDD Showdown: WD Red vs. Seagate NAS
We've wanted to put these two drives together for a showdown ever since Seagate announced its NAS hard drive that competes with WD's Red NAS drive.

Benchmarks - Multi-Client Test

 

The Intel NAS Performance Tool (NASPT) is an excellent way to determine NAS performance in a single user environment. Any review that only uses NASPT assumes that only a single computer will access the target NAS at one time. We took issue with this method of testing and spent over a year designing, building, programming and finally validating the TweakTown Multi-Client Test.

 

The test uses Microsoft Office data recorded to traces and played back to the NAS from up to 120 Windows 7 installations (clients). We record total throughput of all clients and average response time per client.

 

 

Throughput

In our custom multi-client test with Office files, the WD Red ramped up throughput faster and peaked at a higher speed. The performance was also steady with a high user count with the Red, but the Seagate NAS started to deliver inconsistent performance halfway through the test.

 

NCQ Priority Information is a feature not found on the Seagate NAS and we suspect the inconsistent performance with 40+ users is related to this.

 

 

Latency

Latency holds steady through the range, until we run out of CPU processing power in our Thecus N6850, at roughly 100 users.
