I have heard people mentioning that a HDD will fail either at the beginning or at the end of its life cycle, therefore a stress test should be done on all new HDDs before use.
1. Is it recommended to do a stress test for new HDDs before putting it to use in a NAS?
2. How can I do a stress test? Any software needed? How long will it take? Step by step and alternative methods are appreciated.
3. Can I do it on the NAS itself? This is because I do not own an adapter and power supply for a 3.5" HDD.
4. If #3 is possible, can it be done for the second and subsequent drives on the NAS itself while keeping its RAID configuration? Same reason because I do not own an adapter and power supply.
Thanks and appreciate all responses!
Robbie, in the upcoming videos related to the Synology HAT5300 drive, please consider exploring the following topics.
 Is the Synology HAT5300 8TB drive considerably louder than the 12TB model? Assuming that Synology HAT5300-8T = Toshiba MG06 and HAT5300-12T = MG07, the acoustic specifications (idle) published by Toshiba are 34db versus 20db.
 Will the Synology HAT5300 16TB drive be approved for use in a DiskStation NAS? At present, the Synology HAT5300-16T only appears in the Synology Products Compatibility List for RackStation units.
 Please compare a Synology HAT5300-8T against a Toshiba MG06, to contrast the performance of the ‘same’ hardware with different firmware.
 When examining the performance of a Synology HAT5300 drive, please vary the number of simultaneous clients in a multi-user RAID environment. According to Synology’s data sheet for the HAT5300, the drive does not deliver better performance than others when the number of clients is few.
Given all the great advice you have given over the years, I am about to buy my first "real" NAS, the Synology DS220+. My question is: should I buy WD Red or Seagate Ironwolf for the Synology?
I was originally thinking that a pair of 6TB would be good for what I need the NAS to do, but with the WD SMR/CMR issue, I'm now looking at 8TB drives to eliminate that issue. Please can you give guidance on whether the 7200RPM Seagates are more reliable than the 5400RPM WDs? Do they make more noise (the DS220+ will be next to my router in the living room)? Use more power? For backup and media server, any differences?
Any guidance would be very much appreciated. Thank you.
Mixing very similar drives
Immediately after purchasing 2 drives configured in RAID 1 for my new Numbustor-4 (BTRFS) with plans to later get 2 more identical drives to fill up the NAS and go to either RAID 5 or 6, I learned I purchased a lesser drive which I fear may be eliminated from Seagate’s product line by the time I get two more (very little difference in cost – I feel like a dummy for not noticing there were two types!).
My question is if the lesser drives do go off the market and only the better ones are available, can I still do my plan? If not, I think I am going to beg forgiveness from the wife and get 2 more.
