What HDD for Core?

Dupree, being in a similar position, with a core on order, I asked the same question of naim support. The advise given is that the 2 listed are just examples, and that pretty much any HDX would be OK.

i also enquirer about specific drive specs such as read speeds, drive rpm, etc. I was advised that the demands of the core are quite low, and again any good he'd drive would be suitable.

one query is o know what is the limiting factor in drive size? Naim quote 8tb, but what if you source a 10tb, would that work equally well?

I think if Naim say it can handle up to 8TB internally then they probably mean that is the max, not that they thought that would be the most anyone would want to try.....

phil harris told about seagate and also samsung 850 evo. Personnally i would put samsung ssd 850 pro , the best, but expensive ( 1000 eur for 1tb). but i don't know if it is possible( evo yes, but pro?)

Keler, I don't think the Samsung evo can be bought at the required capacity, I think they only go to 4tb

Indeed the first question I would have is to compare SSD vs. HDD SQ within Core. The capacity issue may possibly be addressed via external HDD or NAS.  

Chag -

I have Seagate ST6000VN0041 IronWolf 6TB inside my preproduction box, and a 512Gb Samsung USB3 drive hung off the back too

edited to say i fitted both, device came with nothing

i was not talking about capacity, just 2 models of ssd drives that Phil Harris(naim audio consultant) recommends to the uniti core. All models will not be compatible.

i am personally waiting to hear comparaison between uniti core and unitserve as servers with ndx or nds. which is best in sound quality.

If you convince yourself that the uServe "sounds better," you better think long and hard about whether it's a device you want to and can live with for the long-term. It's one thing if you own one and are "invested" in it; quite another if you are just now looking to acquire a server.  Be forewarned!  In EVERY case I'd put my eggs in the basket of Naim's latest development vs. the unit that was introduced in 2010.

i am not convinced that unitserve sounds better. It is my question. But for now , on this forum, two persons have compared it to the unitserve: one thinks the core sounds better and the other one the contrary. So i just follow the forum and wait. Normally the core have to sound better, but perhaps the sound is the same . I don't know. 

I installed a Samsung EVO 850 2TB, works perfectly

Any thoughts on SSD vs. HDD?  

have you read my posting on storage on core?

It is well worth a read for sure.

But it doesn't, nor do I recall any post doing so, comment on HDD or SSD regarding SQ.

After reading your original article I thought I would swap from HDD to SSD as I didn't like the thought of the HDD whirring away 24/7. But I am waiting for the new Core firmware, with metadata editing hopefully, before swapping the drive and reimporting all my US-based music into the Core again.

Why would a DVR/Surveillance drive be recommended?  They are optimized for constant writes. I would think a NAS drive would be optimum. Good write performance, but more reads.

It's because it runs all the time, unless the Core goes into deep sleep. Phil has previously commented that a NAS drive might be sub-optimal because it could give up trying to read a tricky sector more quickly as a NAS drive thinks of the population of users not just the current read (my words -his explanation was more technical!)

Deep sleep = off

i am far from convinced there is a sq difference 

I don't think there should be a SQ difference either.

But I am occasionally surprised by what I do hear nevertheless when I approach something with scepticism. (Although I don't admit that if Hungry Halibut is listening ....)

If you read the seagate blurb the pipeline series trades off read speed and quick access for a lower noise performance. I had presumed this is why Naim recommended. I have had the core for a few weeks and am delighted. I have now ordered a second seagate hdd as a mirror back up to use along with a seagate usb back up. All are at 4 TB capacity.

Can you post the link?

Thanks

Funny, it didn't show up when I searched "Core"

I think noise is the main issue for me.  My problem is I don't see the Seagate Pipeline for sale here in Canada (the Barracuda is available) I can get the Samsung SSD but I'm put off by the price.  The cost for me off the Samsung SSD is roughly 4.5X the cost of the Seagate Barracuda.  

My plan is to use my Core as a source with no NAS.  I plan to plug a portable drive into the rear usb as a back-up.    

I don't have a huge library - Maybe 400 disks.  So I anticipate 1TB will be adequate for several years.

You may not need as much as you think. I have about 300 discs ripped in WAV in my Unitiserve and it is only about 280 GB.

i believe the Seagate Pipeline is known as "Video" in some markets.
