What to buy?

I'm looking for a hard drive of around 2 or 3TB that can sustain a write speed of over 80MB/s even when it is close to filling up.

Am I right in saying I should just be looking at the WD Black or the WD Red series for my needs?

I'd be inclined to say Black for performance only. Depending upon your needs, SSD caching might be of interest

most drives should manage above 80mbps once nearly full,even the green drives

Not in small non sequential reads/writes, but you'd be hard pushed to find anything suitable, which is why I was digging for more info

only going off atto,but my oldish Samsung 2tb f4 eco green manages around 85/read/write nearly full

empty it manages 130-140 read/write

the newer hdd's are faster still

Yeah sorry forgot to say it will be big sequential writes ranging from maybe 50gb to 400gb over a 3 or 4 hour period. It's for lossless video capture.

Big files - anything new. A green drive might save you a few pennies in electricity, but not much, so whichever is cheaper (guessing Green without looking)

heres what I got with my 2tb,didnt do the whole test as it was taking too long

heres old atto bench when the drive was empty,sorry I don't have any wd to test but they should be faster
