HD Tune performance reading, is it real?

[AGTDenton]

Hi Guys

A friend of mine suggested I test the performance of my disk setup before I put it into production.

I was genuinely intrigued so I decided to download HD Tune and test it on my Stablebit drive pool.

Amazingly it reports 5000+MB/s READ performance. I then decided to test one of the individual disks and got a more realistic 245MB/s.

I then tried Crystal Disk Mark, however, this shows 245MB/s on the Stablebit drive pool and on an individual disk.

Is HD Tune wrong?

My Spec is:

• 4 x 6TB HGST NAS drives. HDN726060ALE614
• RocketStor 6414TS 4-Bay tower
• Highpoint 2711 HBA
• Windows 7 Pro
• i5 3470S
• 12GB RAM

Thanks

The StableBit DrivePool drive isn't a real drive. It's emulated.  So, depending on how HD Tune is testing the performance, it would either be fairly accurate, or completely wrong. 

I'm not really sure how HD Tune is checking the performance, but I'd guess that it's reading internal NTFS data, so that's why it's getting back the super high speeds.  And that is why Crystal Disk Mark is getting back realistic speeds (probably reading actual files).
