Are velociraptors the fastest

lol what is this thread turning into

anyways how many platters does the 500gb seagate have?

is it a single platter 500 or multi platter, that would also make a difference i assume

7200.12 is single 500GB platter

ah thats ok then

i have a few more questions

does the head of drive have a stationary or idle position or is it just random

have you got your drive yet? would love to see some results

might pick a pair of them myself to run in raid 0

also i can see both your points on this,

short stroking would mean the head would only use the allocated 150gb of the 500gb (which is the fastest)

does that mean the head would only ever travel in that 150gb section?

partitioning the drive to 150gb and 350gb and with data only on the 150gb partition should give the same result, shouldn't it?

and for example if you have movies on the 350gb and when you access them then and only then you get a performance hit?

i dunno, i guess testing will only tell us lol

indexing etc means that by partitioning then using the slow part for archive you will have less performance than short-stroking.whether this matters to you is a different matter.

Yes, exactly. And it's not really a 'performance hit' it's just not quite as quick as the outer edge, the slowest part of the drive will still be read at about 70MB/s.....

I agreed with you all along providing the rest of the drive wasn't general use, which doesn't bother me as my back up is all external, therefore I just want the fast outer partition for a boot drive and RAID 0 setup for everything else.

Have to delay my testing, recieved the drive today and just RMA'd it back to OcUK. Stopped my PC from booting when connected and made a beeping noise :confused:

As soon as I took it out all was well...

Outside of benchmarks it hardly matters in the slightest. Same as any situation, doing more than one noticeable read/write operation one a single disk is painful, doesn't matter which part of the disk you're using.

And of course in the real world you won't really notice any difference from any of this at all.

Occur to anyone else that you could also do this with a raptor were you so inclined?

maddness · 21 Jul 2009 at 16:06

raptors are much more expensive and short stroking an expensive raptor will give you heart pains

i had a few raptors in the past but couldnt stand the constant clicking, that would drive me nuts

Short-stroking a Raptor will just make them more expensive per gb than a decent SSD

some intresting pictures on that other page

if your Not intrested int he super fast speeds of SSD buy 2 WD black or 2 samsung F1 (500gb or more) in RAID 0 and make the first partition 200GB for OS, games and programs, you get more performance boost that way then using 1 raptor also far cheaper as well,
if your got £300 to Spend Buy ONE SSD OCZ starting from Agility 128gb (OS/games/programs) and 1 500GB/1TB disk (save Any files onto this disk big and small)
trust me the SSD is 2-10x response time faster then an raptor or any 15000RPM disk
