M.2 is a form factor, meant for laptops.
AIC adapter allows the M.2 form factor SSD to plug into PCIe 3.0 slot
U.2 is specifically for the Intel 750 SSD, some kind of new synergistic thing.????????????? expensive!
SATAe is using 4 PCIe lanes....????????
None required for day to day pc use. but! I feel the need for speed..........
All get 32GB/s speeds, all just different form factors of the various SSD's for PCIe lanes. I generalized a lot, but I read some stuff just yesterday about this.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820228165&ignorebbr=1I'm considering 2 in RAID 0.
As far as mobo question, the 2 boards are practically the same. the g1 has dual lan, 3.1 usb. The UD gigabyte boards are tough, I am using their basic boards, nothing fancy, now. I learned my lesson with an ASUS Stryker Extreme mobo, It was the ethusiasts, OC board of its day. I could hardly get it to run at defaults. unstable, rma'ed 4 times cuz it just quit. So why do I need the G1 if the UD4 will do same with less things that can break.
same sound, lan, ports, chipset, dimms, pcie slots, bios, mostly the same yes?....
Broadwell having 40 PCIe lanes means a whole new line of hardware changes. SATA is done except for storage and backup spinner drives where you want redundancy x10. As long as the base file is saved elsewhere, when an SSD dies u lose nada.
