    I figured I'd put up a thread to sing the praises of these two amazing storage solutions.

    As a professional photographer...I'm always in the search for solutions that allow me to transfer and edit files as quickly as possible. For a while I used the Promise Pegasus R6 to house both my images and a backup. Just a few weeks ago, after getting my new Mac Pro, I decided to take a leap of faith and make a very substantial investment into a couple of new storage options. So far, I've been beyond happy with the setup.

    I purchased four Lacie Thunderbolt 2 PCIe 1TB external drives and set them up into a 4TB RAID 0. Two of them are each plugged into separate Thunderbolt 2 sockets, so that, as a single array, they use two Thunderbolt sockets instead of one. I used this array to hold my current Lightroom catalogue and the corresponding RAW files. The attached file is the Blackmagic test for this array.

    Then I use an Areca ARC-8050T2 to hold all of my subsequent catalogues and RAW files...the idea being that whenever the Lacie array (4TB) filled up, I transfer that catalogue to the Areca array, and open a new catalogue for my current database. The Areca has 8 bays of 4TB WD Red drives installed, in a RAID 10 array which gives me 16TB of useable space. This array gets about 600 MB/s...not bad at all for standard 7200 WD Red drives.

    I now use the old Pegasus 2 R6s as the backups for this setup.

    This setup was a good bit more than I actually wanted to spend...but even considering the significant price paid, I am incredibly happy with the result.

    By the way, the Pegasus R6 is an excellent storage option as well...when I first bought it, they did not support SSDs...but a recent firmware update took care of that problem and they now hold pretty much any hard drive or SSD I've thrown at it.

    So, how's Lightroom performance connected to this generously funded raid? ;)

    Have you considered RAID 10 for the LaCie? That resulting 2TB raid would have better failure redundancy and great speed too.
