Which Barracuda .10 is faster?

sam83uk · 15 Aug 2006 at 19:47

What capasity is faster? I know this is a factor in speed due to the platter size/number

Firegod · 15 Aug 2006 at 20:16

I think anything under the 250Gb size are all quick, but after they start to be slightly slower due to the larger capacity and they also draw slightly more power, again, because of the larger capactiy.

That's if I've understood you correctly.

KillBoY_UK · 15 Aug 2006 at 22:48

as far as im aware its the 320gb and lower were the faster ones

Nocturne_sa · 15 Aug 2006 at 23:01

o man i just ordered the 320 GB... :eek:

..shouldve gone for the 250 ..how slow is it compared to the 250? :mad:

TheVoice · 15 Aug 2006 at 23:04

I highly doubt it's noticeable.

Slackworth · 15 Aug 2006 at 23:57

The 320GB is the best all rounder for speed, capacity and value for money.

Nocturne_sa · 15 Aug 2006 at 23:59

anyone got a clue how long OCUK takes to refund your money (distance seller regulation).. im seriously thinking of sending the 320 gb back and getting the 250 instead (although i havent even received it yet

)... speed being the issue... :mad:

There is absolutely no need to send it back, you will NOT notice the difference in speed if there is any at all. Be happy with your purchase!

maranello168 · 16 Aug 2006 at 01:01

i would say keep the 320GB

SiriusB · 16 Aug 2006 at 02:36

I doubt you could tell the difference between the fastest .10 and a Maxtor so I really wouldn't bother sending the 320GB back.

Lol, you really would not notice the difference in speed between the 250Gb and 320Gb version. If you want speed, why did you not go for a Raptor or even SCSI?

james.miller · 16 Aug 2006 at 09:05

320gb = best all rounder/VFM as Mr. adwhitworth rightly said. the higher capacity drives are the fastest, due to a combination of higher density platters and more platters to begin with, both of which lead to higher sustained trasfer rates.

Nocturne_sa · 16 Aug 2006 at 09:35

alrighty then... cheers ppl... itll stick with the 320 then...

Are you sure on that? Not trying to cause bother

but reviews of larger drives always say they are slower than smaller capacity drives due to the larger density and more platters, as it takes longer to get to the data?

james.miller · 16 Aug 2006 at 11:08

thats generally true, and there are conditions where the 750gb loses out to the 500gb ect, but it also has a higher sustained transfer rate - the highest of any 7200rpm drive available. Its swings and roundabouts mate, but overall the review are all placing the 750gb at the top of the roost

Ah fair enough, cool.

Cheers for that!

All 7200.10 drives use platters with a density of 188Gb/platter, so they should all have roughly the same linear sustained transfer rate characteristics. So it really doesn't matter much which drive you get in that regard (linear sustained transfer rate.)

http://techreport.com/onearticle.x/9857:

"Seagate has now made public some new information about the 7200.10s, including their cache sizes and platter density. The 750GB, 500GB, 400GB, and 320GB models all have 16MB of cache, with the 250GB available in either 8MB or 16MB variants, and the 200GB only shipping with 8MB. The drives' platter size has also been revealed to be 188GB/platter across the entire line."

This high areal density is why in sustained transfer's the 7,200RPM .10 Barracuda can meet or exceed that of the 10,000RPM Raptor.

yes, except some have more platters and heads than others dont they

http://www.trustedreviews.com/article.aspx?art=3042

look at the 750gb compared to the 320gb - twice the platters and read heads.

Elric · 18 Aug 2006 at 17:01

Dont worry about the 320. I have three of them, nippy as hell.
