I know that hard drives aren't the coolest components out there, but hey, I'm a hoarder, and it looks like I'll be in the market for something around the 4TB range fairly soon. (I just did a really quick cleanup of my main data partition this morning and got back to around 280GB free, but then I took the Uplay+ promotion and downloaded AC Odyssey and now I'm down to 170. I guess I'll uninstall it when the month ends and there's more crap that I could get rid of, but the writing is on the wall - I need more space.) Therefore, I took a look at the hardware listings and saw that 4-6TB drives cost around what I expected, but then I noticed a weird thing - all of the drives were 5400 or 5900rpm models. Last time I bought a hard drive, normally they were spinning at 7200rpm, except for WD Green and the likes, cheap models which were usually built to a lower quality standard and thus less reliable, but now it's WD Blue and Purple and various Seagates too. So what gives? Are all HDDs now crap, or are WD Blues, Purples and other stuff rated for 24/7 operation still fine? What about the performance? I know that, due to the high density, they should be just fine as far as sequential reading is concerned, but seek times on 3.5" 5x00rpm hard drives?! Sounds bad! But how bad is it? I'm fully aware of the existence of SSDs, but at the moment, I need the space more badly and funds are limited, plus I'm curious, so what gives? Is 5400rpm the new norm? Are the new drives as reliable as the old ones and are they actually worse performing, or is there some trickery, like more heads?
