Hello, I'm looking to update some of my drives (mac pro 2009) and I'm hesitating between two drives. One of them has higher sequential R&W speeds while the other is faster in random R&W. The drive is not going to be used for OS (got that on a SSD). The task which will test the drive the most is opening hundreds of NEF files in Photoshop (average file size = 25MB) as well as saving PS files (bigger file sizes) and saving hundreds of jpeg files in a batch (average file size = 7MB). With such files sizes, is sequential or random speed more important? Thanks.
