Brand new Win 10 build

i3 /Gigabyte GA-Z170N-Gaming 5 / 16GB / Samsung SM951 256GB M.2 PCI-e Gen3 8Gbps x 4 AHCI Solid State Drive

Seemed to be working fine, I then added a 3TB WD Red drive today for storage purposes and drive is detected / formatted through Disk Management etc but either reading or writing any data to it and the whole computer goes slow (ie starts writing at about 100MB / s but within about 10 seconds it falls to <1MB /s and stays there) while anything else , lets say IE, goes unresponsive etc etc

Device manager everything appears installed /recognised correctly (although strangely the Bios doesn't recognise the Samsung as an NVE drive - but still boots fine albeit a little slow ~45s to password box)

I'm just going to be writing a lot of BD rips to the WD drive while I save up for a new NAS system, but this performance (90 mins to copy a single sub 20Gb file) just feels majorly slow

Any ideas greatfully appreciated

Thank you bledd - spot on, hundreds of errors mentioning bad blocks

Just running a "data lifeguard diagnostics" tool from WD's website (which looks like it will take 400 mins / 6hrs + to complete, although its probably an immediate return anyway

This is why you should NEVER do a 'quick' format on a new drive!
Always do a FULL format as this would have detected the bad sectors during your DOA window.
