Hi All, First time poster, long time MacRumors reader. A quick thanks to everyone here for their great insights over the years. I just received the nMP (6-core/16GB/512GB/D700) and started setting it up. I noticed something interesting - I tested the speed of my external USB 3.0 drive and noticed it ran at least 50-60MB/s slower than on my 13" rMBP (2013). The external drive is an Intel 520 480GB SSD in an Oyen Digital USB 3/eSATA enclosure. On the rMBP it works amazing, actually was faster than the Seagate thunderbolt adapter, which I sent back. AJA: ~400MB/s read/write on the rMP vs. mid-300s on the nMP BlackMagic: 400+ read on the rMBP, mid-300s on the nMP Anyone else noticed this or would know why this is? Thanks!
