Naravno da postoji razlika i u praksi, ali je iskljucivo ovisna o onome sto radis na kompu (velicina transfera, te o Cluster Size-u).

Razlika je ~10% na strani 64KB (za OS npr.)

Ako je rijec o vecim fajlovima (storage) onda je ipak bolje 128KB.





Evo i par svjeta o postavljanju diskova:

1) 3072 sector offset = works. I observed performance increases no less than 12% avg (see below) – and I did some pretty extensive and specific testing.

2) Disabling NCQ. I was surprised to find that this helped increase average speeds up to 9%. Once you've installed your OS, go under your device settings, select each of the three nVidia RAID controllers (Port 0 & 1 tabs) and uncheck the "Enable command queuing". Click "no" to the restart option, until you're done your last.

3) Contrary to what you might read out there on the subject, disabling your Write Cache WILL cripple your drive speeds. Maybe I’m doing something wrong, but I strongly recommend against disabling Write Cache.

4) Your first partition will be the fastest (closest to edge of disk), so if you were really anal, you should create a parition for your games, and THEN your C: partition.

5) If you’re going for pure performance, and want to use the full 6 drives in RAID-0, try not to get anything larger than 320gb – with nForce having only 32-bit LBA addressing, your limit for an array will be 2tb. Might as well just go with six 150gb Raptors

6) My particular time simulator is bias towards equal read and writes. You may find your usage warrants more emphasis on reads than writes. If you would like, I can send you the time simulator spreadsheet, and you can edit the number of files in the simulator.
