Re: A fair response.
Agreed laptops are a significant compromise. I had a work 16GB (two channel) i5 T450 Lenovo Ultrabook with SATA attached SSD, but cursed the lack of IO bandwidth; my new i7-6800K desktop, at home, with NVMe attached Samsung SSD 950 PRO, 32GB RAM (4 channel) and NVIDIA 1060 GPU is so much faster and easily worth the extra cost! My stopgap i3 HP laptop at home is now rarely used on a Dell USB3 dock.
Out of curiosity I did some research on the /costly/ Razor Core GPU enclosure for laptops and apparently you lose half the speed of a GPU mounted in a desktop PC, so it looks dire value!
I stopped bothering with fake RAID in desktops years ago, I now use and occasionally build new FreeNAS boxes with many-TB ZRAID2 arrays of WD Red drives and Parity RAM which are /much/ safer and faster than fake RAID and tired RAID 1 or 5; I share these on my Gigabit LAN and WiFi with multiple devices including Android tablets.
