Transferse is slow.

I am tranfering from a m2 to a network drive. Hooked up to USB 2, Going 2ish meg a sec. no idea why it is so slow, I am doing it in linus, but other transfers arent this slow. Umder 700 gigs been a few hours only half way.

You do not mention if this is lots of small files or a few big ones. Small files will go painfully slow, even worse over a network, whereas larger files can be quite close locally and over the network.

M.2 is a connector type. Doesn't even have to be storage. What matters is NVMe (and what PCIe generation) or SATA. Even at SATA speeds of 600MB/s, though, you're ultimately limited by either you network link speed and/or the USB 2.0 connection. Assuming a fairly standard 1Gbps LAN, that's a maximum transfer rate of 125MB/s. USB 2.0, though, has a maximum transfer speed of 480Mbps or 60MB/s. Therefore the absolute best case scenario is around 3.5 hours to transfer 700MB to a drive over USB 2.0, networked or not.
