Access times are totally horrible. 20ms. lachen.gif The first 300GB is good and fast, so that's fine for OS/Apps/Games - but the rest is too high... way higher than most 5400RPM drives. Good for storage, but not so great for other stuff.
I'd try flashing the drive's firmware to see if that helps:
http://knowledge.seagate.com/articles/en_US/FAQ/223651en
And if it doesn't, partition it in at least two. Make the first only as large as you need for games (or other active data on the drive), and then make the second for storage of anything that isn't accessed at the same time as your games. That should keep access times as low as possible when playing. thumb.gif (I suggest this because if access times get too high, some games or engines will fail to load important models/textures/files before they are needed, which can cause stutters. Keeping all the data close together towards the edge should help prevent that.)

Some have burst speeds higher than that. If a drive were doing something highly sequential (video editing/encoding, benchmarking, etc.), then it might matter - but for Apps/Games and regular usage it does not.
Edit: Have you checked if you can adjust the AAM settings in HDTune? It looks like a pretty good drive for the price. smile.gif But if you can figure out how to drop those access times, it'll be way faster. That would take it from a good deal to a really great deal. thumb.gif
tried to update the firmware and it was up to date already,.I do not know too much about HDDs but I was going to ask about the benifits of partioning a drive, but looks like you beat me to it. I'll try and set up a 500GB partion for games and report back wiith the results.

Not sure what AAM settings are but I'll have a look around and see what I can find in HDtune

edit- well my drive doesn't support AAM settings, or at least not how it is currently set up. Partitioned it into 3 new volumes to see if that helps my times at all. Will post back some new results when HDtune is done. Any advice on how you could think to make it faster wopuld be much appreciated!

new bench with 3 volumes, didn't help much

Edit 2 - just saw this deal on Amazon. $90 for this drive

AAM is Advanced/Automatic Accoustic Management
http://en.wikipedia.org/wiki/Automatic_acoustic_management

It makes drives less noisy when seeking, but the tradeoff is access times. Some drives have it turned on by default, and some have it turned off - your drive probably has it forced on, and doesn't allow it to be configured.

It "didn't help much" because HDTune tests entire drives rather than partitions. Notice the scale at the bottom of the graph? If you want to check how it performs for a 500GB partition, you need to enable the 'Short Stroke' option and enter in 500GB. I think you'll find it performs quite nicely when only dealing with a smaller amount of platter.

Looks like you got the sequential speeds fixed. 168MB/sec avg sequential... you'll be the envy of many people here once they see that. biggrin.gif They'll be even more envious if a 500GB test shows good results.

read up on a bit on short stroking from a guide on here and that helped. here are the new results with a 500gb short stroke. yes im using a virtual keyboard cuz mine doesnt get here till monday lol.

338

edit from brother PC - got those access times way down compared to before, 13.3 I'll take that. and those sequential times went up even higher too biggrin.gif
