External Hard Drive OK with Audirvana?

Rate this topic

Recommended Posts

Hi folks: sorry if this is a dumb question, but I wanted to ask if there are any reasons why I shouldn't be using an external HD (Seagate SSD Portable) to store my Audirvana library on? It's plugged into an older Macbook Pro, which in turn is connected to a Chord 2cute. I have a number of DSD files, and I wondered if there might be any speed issues with the data going through the Seagate's USB 2.0 cable to the laptop? Any and all advice gratefully received, thanks...

I have most files stored on external drives and have no problem playing DSD. I am using other players instead of Audirvana, but used Audirvana before, no issues because of external storage.

I do exactly that, times two. I have one portable USB hard drive connected to a bridged Mac Mini, and another powered HD connected via USB to the Airport Express Base Station, essentially an NAS.

 

I used to have dropouts and slow connection/lag issues using a very old NAS when playing DSF files, so I switched to external hard drives and have no throughput issues. I do upsample all files x2. Lag issues did not affect anything other than playback of hi rez files, i.e. 16/44 wav and FLAC files never had problems.

Thanks guys: much appreciated. I wanted to make sure I hadn't inadvertently added a choke to the system. I run 24-bit files, and as you can imagine, I can't store them in my laptop.

 

Cheers and Best,

Dave

@Dave Hansford consider this:

 

The theoretical highest data transfer speed you get for a USB 2.0 interface is 480 Mbit/s, or 480, 000 kbit/s.

 

Uncompressed Redbook audio is 1411 kbit/s.

Uncompressed 24/192 PCM audio is 9216 kbit/s.

Uncompressed DSD 128 is 11, 288 kbit/s.

 

Can you see why audio will not choke your system now?

Re a bridged macmini, is it possible for a ThunderBolt only HD, with TB to gig ethernet adaptor, to be directly connected to a router for access by the macmini? Or any way for it to be connected straight to the macmini?

(bridging to router has taken up the TB input!).
