Cia jau matkiu subtilybes, o ne z170

z170 duoda SATA3.0 6portus,  20PCI-e lanes, USB 3.0 Up to 10
Ka su sitais reikalais nuveikti sugalvoja ASUS ar Gigabyte - ju reikalas.
Z170 negarantuoja tarkim Intelinio LAN, tai nera chipset'o reikalas.

Visokie USB3.1, m2, sata express'ai << lego rezultatas.

Kas asmeniskai del m.2 ir SATA Express << fak, ka cia prigalvojo, net knisa aiskintis :)
m.2 portas + m.2 device'as .. na OK, principe tinka.. greitis galimai didesnis, forma patogi..

Red: Legacy SATA per SATA Express'a == tai jei Legasius, tai ir pajungsiu per SATA..
Orange/Purple: PCIe SSD .. NVM moderniau/geriau.. sakyciau 
su laiku turetu issigryninti velniai zino kokio plocio portas i tiesiog PCIe linka.

3 SATA Express Connectors for up to 16Gb/s Data Transfer

SATA Express interface supports both PCI Express and SATA storage devices by 
exposing multiple PCI Express lanes and two SATA 3.0 (6 Gbit/s) ports through the same host-side 
SATA Express connector. Exposed PCI Express lanes provide a pure 
PCI Express connection between the host and storage device <..>

16Gb/s .. tai jei  two SATA 3.0 (6 Gbit/s) << cia yra 12Gb/s .. jei 2 PCIe3.0 lanes = 2*8GT/s = 16Gb/s
Prie ko cia tas "SATA", jei tie 16Gbps eina per "pure PCI Express"?

3 x SATA Express connectors
6 x SATA 6Gb/s connectors

Kitas dalykas.. Z170 duoda 6 portus SATA3, Gigabyte deda 3 SATA Express'us.
6 portu jau reikia vien SATA Express'ams, tuo tarpu dar ir paprastu 6 portu ilituoja.
6+6=12vnt. ... cia multiplexina ar koki sh?

* Refer to "1-7 Internal Connectors," for the supported configurations with the M.2, SATA Express, and SATA connectors.
kazkaip irgi neradau uzuominu apie kokius limitations
