WD Red’s are tried & tested - but not the Pro-Red’s they are intended for business & high speed access.
I read good stuff about the IronWolfs, nothing much to choose other than Red’s are more economical running slower disc speed, quieter & cooler. Whatever the MTBF on them is exceptional. Personally I would stick with Red’s as thats what I have & zero problems for 5 yearst. , .
Just been through a similar decision…I decided to go with the IronWolf drives. I’ve only had them in place about 3 weeks and all seems well. Certainly the WD Reds also seem like a good option. I stuck with Seagate primarily as I had Barracuda drives before and they had been in my NAS for 9 years without any issue so couldn’t complain. Only time will tell. The drives do make some noise, it’s not a problem for me as NAS no where near the music room but that might also be a consideration for you.
I looked at the specs and pricing comparing Seagate The Iron Wolf and WD Red drives. The Iron Wolf drives were slightly cheaper and slightly better spec (including slightly lower power consumption, and hence running very slightly cooler), the biggest difference was a better MTBF for the Seagate drives.
I does seem like a straight two horse race between the tried and tested WD Red, and the newer kid on the block in the Seagate IronWolf, with the WD slightly in front.
The NAS will not be used to stream music, but will merely act as a backup to the 2Tb drive in my HDX ripper/ server, so at least I won’t have to get into the debate over which third party UPnP server or ripping software is best.
I’ve been running two Ironwolf 10TB drives in my 718+ for a year with no problems. I run a UPS on the NAS (and have a secondary NAS that is used as a backup, plus regular USB backups), so that plus the 2 drive mirroring should be enough to resolve my data loss paranoia
There may still be someone left at Naim who is able to do this. Otherwise, given that I managed it, it’s not impossible. Naim did publish a how-to guide, which may still help, despite being written for a much older Synology model. https://www.naimaudio.com/sites/default/files/kb/RS2105_Synology_DS212j_Setup.pdf
Use this, plus the info in the HDX manual, and you’ll get there.
If you have WAVs, I would convert them all to FLAC before doing anything else.
As someone who, rightly or not, has convinced himself that WAV sounds better than FLAC, I’m reluctant to do this, though I do accept that FLAC handles metadata better than Naim’s proprietary version of WAV, particularly if I ever moved on from Naim gear.
I know that I can have them convert back to WAV on the fly for replay, but then that opens up the whole question of the processing affecting SQ.
If I simply back them up as WAV from the HDX, would I not be able to convert them to FLAC at a later date, should that ever become necessary?
If you convert to FLAC after transfer, it’s too late, the metadata will not be properly added into the FLAC files, so you need to do it on the HDX. (It takes a while if you have a large library, but when you do your initial backup, it will then be much quicker with the reduced file size.)
On my Unitiserve, I listened to various different albums before committing, and concluded that FLAC converted to WAV on the fly sounded identical to straight WAV. The streamer would get the exact same WAV fed to it either way, so I wouldn’t expect anything else. How this would go using the HDX internal DAC, I wouldn’t know. After all, the whole point of feeding WAV to your streamer is that the workload of unpacking FLACs is done remotely on the server.
The main advantage to my mind is that you can then run a UPnP server on the NAS, so it your HDX stops working, you don’t just have a backup of the music folder, you have a complete backup server that allows you to continue listening while you get it fixed.
If you have a bit of time before you reach the point of no return, I would suggest converting a few albums to FLAC, and having a listen. Then turn on transcoding on the fly, and see if it sounds any different to straight WAV.
Arghhh … so are we saying that if the HDX were to pack in, and having simply backed up the Naim rips in WAV to the NAS, if I then subsequently installed a UPnP server on the NAS, that software wouldn’t find the metadata contained in the Naim WAV rips?
