Last Friday, I bought a new Red 8TB (WD80EFZX-68UW8N0) to add to the two 3TB Reds (WD30EFRX-68AX9N0) in my Synology 918+. I was surprised by the noise to put it mildly.
I know the Red Helium drive seeking is supposed to be slightly louder as per the knowledge base, but didn’t expect this loud.
Still, some (here, on Reddit, etc.) call the drives “much louder” while others say they can’t hear them - it’s rather subjective and not easy to compare with random isolated recordings from others. The “How to tell” knowledge base article doesn’t really help here either.
But since the Synology spins up the drives in order, in my case it’s easy to make a direct comparison. This is a single take recording of the spin ups from about 1 foot away from the NAS - no edits, except slight noise reduction (to make the 3TB drives actually audible over fan noise etc. - in their five years of service I’ve hardly ever actually noticed them) + 12 dB (linear) amplification:
00:00 - first Red 3TB drive spins up
00:09 - second Red 3TB drive spins up
00:15 - Red 8TB drive spins up
The sound level when generally seeking remains the same as right after the spin-up (not the grinding at 0:31, but the rest). Haven’t heard this level of hard drive noise since the early 90’s.
I’ve done Synology’s Quick and Extended SMART tests, which both report the drive as healthy, and the SMART info after those tests also looks OK to me. Performance is also good.
Since I only have a laptop around at the moment, and no e.g. USB-to-SATA cable, I can’t test the drive on Windows yet - but for now, just checking if this noise is to be expected?
