Large slow energy efficient disks are extremely useful for storing the main bulk of images I find, and slow is relative, even my 5400rpm disks in a NAS across an (admittedly fast) network can write images out vastly faster than darktable can do the processing to produce that export file. Using a faster disk here really won't buy all that much.
Where disk speed does give a real benefit is for temporary cache files and anything doing random access such as the sql database. For that sort of stuff the faster the device the better - and SSD is king. -----Original Message----- From: Tony Arnold [mailto:[email protected]] Sent: 21 March 2013 23:48 To: [email protected] Subject: Re: [Darktable-users] Difference between i7 processors for Darktable Luis, I was once advised by a previous boss to always buy the machine with the best performance you can afford! Is there any choice in disk speed? I would avoid 5400rpm disks (are they still sold, I'm not sure). I would think that would have an effect, especially if you are exporting a large number of images.
