Hi, I need some information that I'm having a hard time finding online. Folks here are probably my best bet I have a 2012 iMac, 1TB fusion, the rest is maxed out. I mainly do Lightroom + photoshop + iMovie - all with huge files. I want to put my photos/videos on an external SSD. My assumptions is that an external SSD, connected via Thunderbolt will be much faster than the internal fusion drive, especially if the external SSDs are set up in Raid 0. I got the Lacie Little Big Disk 512 SSD (Thunderbolt). The whining of the fan drove me crazy so I returned it. I didn't think of removing the fan as I just realized some have. I'm about to order the Pegasus J4 instead. The information on the J4 is hard to come by but from what I've read it's pretty silent and the performance is great. I also like that it's expandable to 4 drives. I plan to get 2 x 256 SSDs and set them up in Raid 0 in the J4. 1/ Do you guys agree that this will increase speed substantially vs. the internal drive 2/ Do I need to get top tier SSDs (like OWC or Samsung 840 Pro) to make the best use of the J4 or whether, given that I'm going to set them up in Raid 0, I don't need to go overboard and get the best possible SSDs? 3/ Fan noise: can someone confirm that the J4 is more silent than the LBD? 4/ I know that the J4 has a user serviceable fan, which means that I can remove the fan if I find it too noisy. How safe is that given that I'm going to have SSDs in it? Thanks!
