Unitiserve HDD vs SSD

Posted by: AlainRch on 22 June 2013

Hi

what is the best choice between HDD and SSD ?

FWIW I had an OCZ SSD in my PC that just suddenly died. The only good thing was that the replacement sent under warranty was a better (faster) product. Fitting the SSD to my PC made it go so much faster that I have not bothered upgrading the CPU.

 

I have spinning disks in my NAS because they are larger and cheaper.

sounds like a very good setup that you have with low risk. How do you backup your music to a remote NAS? I also understand that all NAS will have some noice based on your experience, and therefore shoudl focus on putting somewhere far away.
 
Of course if a nas can be hidden in a place where noise is not an issue, and you do not run a risc of overheating the unit this  is the best way to do it. In my Apartment there is no room where I can store a noisy nas away. Therefore I did not get a nas until I was sure that the unit was very close to silent. I bought a readynas duo v2, that sits under my desktop. I can only here it when I have turned  my laptop off and I am not playing music.

Claus, i am in the same position as you now, but in a few month i will move to a bigger appartment and hope to put the nas somewhere.

Still would need to be silent - thanks for the tip, any experience with different HDD vendors/models in terms of noise and reliability?

Thanks
Lars

did you have a chance to listen to an Aurender S10?

SSD and HDD onboard, only digi out, ipad app and extrem building quality!

I like this design of this server very much...

I heard an Aurender into a MSB dac...very nice.  The app is excellent,

 

Aurender can read from a NAS but two years later, still a primitive process.  Fill the HDD and then what?!?

 

Aurender has a two year warranty...not sufficient for this kind of product, IMO.

 

7K USD...

Errmm those people who think SSDs are better than a HDDs from a failure point of view need tothink again.

Yes an SSD is faster and has no moving parts but all SSDs fail just like HDD and unfortunately when they fail they tend to fail completely with no chance of recovering anything.

Even worse SSDs fail without giving you much warning whereas a HDD will typically generate errors for some time before it fails.

My local dealer is talking about the (new?) helium-filled hard drives by HGST (owned by Western Digital).

Probably just a lot of hot air....

 

sorry

There is also the SSD/HD hybrid drive...although I have not heard of one in a NAS yet, just PC's

 

Possibly, more trouble than they are worth.....

SSD drives usually implement the same smart monitoring technology as spinning drives.  You can monitor the drive health if your are inclined.  In the early days of ssd,  drive controllers often failed.  The newer generation have much greater reliability.  That said, the real chance of any drive ever failing is quite minimal. (My first hard drive 50mb IBM is still running after > 20 years)  The only time I've experienced is failure was via USB interface when accidentally shut off / unplugged during write operation.  A ssd would not suffer a head crash and would survive such an event.  (Of course I always purchase high quality drives.)

 

if you really want a good backup solution, don't use a hdd or ssd.  Use tape or better look into Amazons Glacier long term storage solution.  The cost is about $.01 / GB / Month.  Completely secure and quite easy to use.

I use tape.  But I can no longer enter my cellar, as it's full:
