Seagate IronWolf Pro 20TB HDD Review

We tested the 20TB Seagate IronWolf Pro with a number of scenarios that it may face in the real world. The settings for these scenarios are as follows.

File Server
512MB file size, 16KB Block size
80% Read 20% Write 100% Random
I/O queue depth 128

Web Server
1GB file size, 16KB Block size
100% Read 0% Write 100% Random
I/O queue depth 64

Database
2GB file size, 4KB Block size
90% Read 10% Write, 90% Random, 10% Sequential
I/O depth 128

Workstation
1GB file size, 16KB Block Size
70% Read 30% Write 50% Random 50% Sequential
I/O depth 64

The 20TB IronWolf Pro handled the workload scenarios pretty well, with the fastest bandwidth speeds we've seen to date for the File Server test (10.24MB/s) and the Workstation test (5.59MB/s). It didn't fare so well in the Database test with a bandwidth figure of 1.36MB/s.
