so im thinking of getting a new hard drive to use as a storage disk, but then i got to thinking about the age of my current 320gb main disk, and wondered how fast new drives will be in comparison, these are the scores for my current two, first being my 320gb the second being a slightly newer 500gb in the same machine, want sort of speeds would say the seagate 3TB barracuda thats on special atm score at?

Code: 
sudo hdparm -tT /dev/sda
/dev/sda:
 Timing cached reads:   21464 MB in  2.00 seconds = 10742.66 MB/sec
 Timing buffered disk reads: 210 MB in  3.01 seconds =  69.78 MB/sec
sudo hdparm -tT /dev/sdb
/dev/sdb:
 Timing cached reads:   21304 MB in  2.00 seconds = 10662.50 MB/sec
 Timing buffered disk reads: 252 MB in  3.02 seconds =  83.39 MB/sec
 
you need to benchmark your hdd with atto,the 3tb seagate would be around 150mb read/write

i dont know if youd notice the speed difference,if you put your os on an ssd then the speed difference would be huge

this is from the first disk, same as hdparm virtually, the second was the same as from hdparm too at 512k it seems sin_chase made a thread benching the 2TB version of the seagate on which is helpful tho ^^ totally missed before
 
yeah it will be faster than your current drive,remember though his speeds were on an empty drive,as the drive fills up speeds will drop off
 
im hoping itll be a while before ive filled 3TB to any large degree at least :) ordered it now, according to smart the 320gb im replacing actually has a dozen or so reallocated sectors so it wasnt in the best state even considering its low capacity and slow speeds.
 
/dev/sdc:
Timing cached reads: 22094 MB in 2.00 seconds = 11058.69 MB/sec
Timing buffered disk reads: 518 MB in 3.01 seconds = 172.23 MB/sec

much better from the 3TB, well over double the speed of the old one
