TO NAS, or not, TO NAS

Oct 19, 2013 9:00 PM

I'm setting up my digital eq work flow(chain).

Been reading the DAM book.

Peter Krogh says that he doesn't personally recommend using NAS as primary storage

as of the writing of the last version of the DAM book....2009.

 

I bought a Synology 1813+ to handle all the digital files in my life 8tb total.

I want to put my photo library on there and run lightroom and photoshop.

I will keep the lightroom catalog on the local drive...my smoking fast macbook pro SSD.

Used to use the 1st gen intel tower but the laptop just blew its doors off.

 

Is this safe?

or should I use a NON-NAS primary external?

 

Ultimatley, one of the following two set-ups were what I had in mind...

 

NAS>local back up & glacier

OR

External NON-NAS > NAS > glacier

 

Thank you for any advice and opinions,

 

Alex

    I don't have my copy of his book to hand - does he give a specific reason?

    Others may not agree with me, but my view is that the primary purpose of a NAS is to enable sharing of data across a Local network. So if there's no requirement for that level of sharing of original image files, what's the point of putting them on a slower (and possibly less reliable) medium?

     

    I keep all my image files on internal drives, but even if I couldn't do that I'd use fast external drives (eSata or USB3). I do use a NAS, but it's only used as one of my several external backup devices, plus some file sharing between the family members.

    Yes, my primary's a Synology NAS as, like you, I'm primarily MacBook Pro based.

     

    I emailed Peter to check his current thoughts on the matter, and forwarded the reply he'd sent to you, confirming that he's more comfortable with images stored on NAS now as long as it's a good quality like Synology.

    I would think the primary reason not to use NAS for primary storage would be *speed*. I'm not a Mac user so can't comment on what the latest interconnects are for these systems, but most (modern) internal HDD interconnects are much faster than the gigabit interconnects used to transfer data between the host and the NAS device(s) (even the Synology, which tries to optimize the 1GB LAN ports by using link aggregation). SATA 3 can handle up to 6GB/s so it's native link speed is a factor of 2.5 or 4 faster than the NAS.

     

    Of course there are plenty of other factors that contribute to speed/performance so this isn't the only consideration, but the general question regarding why Peter briefly mentions not recommending this (I see the reference is my copy as well) likely relates to speed. In the end the speed question is also partly related to how Lightroom manages disk i/o. I've not really noticed LR being very disk bound (mostly memory and CPU bound from what I can tell), so perhaps the disk i/o performance isn't all that relevant to LR...

     

    I briefly just looked at Apple's Thunderbolt technology (which is apparently available on the Mac Pros) and this seems like a much higher performing interconnect for external peripherals (including NAS devices like the Synology). Obviously, technologies/devices like this render the local vs. remote interconnect performance differences moot .

    Ya, that is one impressive box to be sure! Too expensive for my home needs, but I've been wanting to get a Synology DS411slim ever since Linux Torvalds solicited feedback on G+ for his home backup needs (https://plus.google.com/+LinusTorvalds/posts/REfnCV1y8Dy and https://plus.google.com/+LinusTorvalds/posts/hvnMn1fFKEm) .
