Lies, Damn Lies, and Benchmarks
If you’ve noticed, we don’t publish IOPS or latency numbers for TrueNAS or FreeNAS storage. Now, we realize if you’re comparing storage solutions by looking at brochures and fact sheets, this might be frustrating, but I assure you we don’t do it because we’re hiding anything.

Also supported is the SCSI UNMAP command, which is used to recover capacity when a VM is moved or deleted.
A Complete Guide to FreeNAS Hardware Design, Part IV: Network Notes & Conclusion
