I have an iMac with an SSD 250GB drive in which my applications are loaded and a further 2TB drive in which I would like to load Logos data on to. Can I do this an if so how do I go about doing this? Thank you. Alan

You will need to choose Custom installation process during the setup of Logos, and choose the 2nd drive for the entire installation of Logos. The software and the books can't be installed on separate drives if that was what You were asking.

The performance drop would be palpable. I wouldn't recommend it.

Thanks for your advice. I will need to consider whether this is the way I should go as I am aware that some of the performance may be lost in the process.

"some" is a conservative estimate.

I'd guess something in the neighborhood of a 5-10x drop in speed.

However the wiki does have instructions for installation on more than one computer, that would work for you. You basically copy some files out of the Logos director, uninstall logos, re-install logos ensuring you check the box about not checking for updates on first load, then start Logos with the ctrl button pushed, use the scan command, and viola.

Consider putting other programs and/or their data onto the 2 TB drive. Otherwise you can use symbolic links in OS X to put your Resources folder onto the drive whilst Logos thinks it is in its original location.

Welcome Big Smile

Thread => Install on SSD includes symbolic link discussion

Likewise have an iMac with 250 GB internal SSD; planning to add Thunderbolt external SSD RAID, which should be as fast or faster than internal SSD.

One external Thunderbolt RAID is drobo mini => http://www.droboworks.com/Drobo-Mini.asp

Alan, I have a late 2010 MacBook Air with Logos 5 installed to an external storage volume and it works well for me. Many posts postulate severely degraded performance - not my experience. My setup is straight forward but atypical.

I suggest you consider a trial run. If you temporarily setup a new user account on your iMac you can make a separate Logos 5 install to this user account trying the symbolic link solution and locating the linked to elements on your 2TB hdd. You can use the Scan command to import copies of resources from your existing installation to save time versus downloading.

As to performance I have two actively used Logos libraries - separate accounts - installed for use on my MacBook. I have a smallish library installed natively on OS X Snow Leopard and a considerably larger library installed natively on Windows 8 Pro using BootCamp. The smaller library is installed to the internal SSD. The larger library is installed to a microSDXC card attached via USB 2. In day to day use the difference in perceived performance is not severe.

For additional comparison, I have a separate installation of the larger library on a Dell M6600 workstation, running Windows 7 Pro 64bit, with a 2.4GHz first generation i7 quad core, 16GiB RAM and, a 2GiB NVidia Quadro 3000m GPU. My impression is that CPU, GPU, and RAM effect perceived performance more than Disk I/O except when indexing.
