How to get a high HDD score on pcmark2002?

[vaporize]

I read a lot of posts with new hard drives (7200 rpm, 8mb buffer) that are scoring around a 1000 HDD points on pcmark2002. But I am seeing many scores on futuremark site that go all the way up to 13000. I know these people didnt spend a ton of money on just their hard drive so how did they do it? I want a score around 8000+. Is this something to do with RAID or combining 2 hard drives. Can someone tell me what hard drive and configuration I should use to get these high scores?
p.s. I know these scores arent important in real-world but it gets me to work toward something so that I will have more info when I build my new comp in a few weeks.
-thanks

Well a RAID-0 array (striping) will improve performance.

Better than me explaining it, here's a quote from Tom's Hardware Guide:

RAID 0 is using a mechanism called 'data striping'. It maps data across a number of different hard drives to create one large drive. The data is stored onto the physical drives in consecutive 'stripes', which are of defined size. This means that a file that is larger than the actual stripe size is distributed over the hard drives in the array, so that the different stripes of that file can be read in parallel. In this case the data transfer rate of the RAID 0 Array or 'Stripe Set' is the product of the data transfer rate of the slowest drive in the array times the number of drives that are in the array. If identical hard drives are used, the data transfer bandwidth is simply multiplied by the number of drives. A stripe set of four drives with a data transfer speed of 20 MB/s can therefore reach speeds of 80 MB/s, because data is read or written to or from the four drives in parallel. Of course this example is only valid if the data is indeed distributed over all the four hard drives. Making the stripe size small enough can insure this.

The bad part about striping is that if one HD dies, you basically lose all the data...

Of course, the people with the really high scores are probably using like 15,000 rpm SCSI hard drives. Those are really expensive, even for small drives (like an 18 GB Seagate is about $350)...

18 GB SCSI is about $150 if not less

 

[Goosemaster]

Here is whatyou can get for around $350


1 Maxtor Atlas 10K III "Orca", 73.4 GB, Ultra160 Wide LVD SCSI-3, 10,000 RPM, 4.5 ms seek, 8MB cache, A/V Rated, 3.5" LP, 68 pin interface, 5-year warranty.

OR



Maxtor Atlas 15K Ultra320 SCSI, 36.7 GB, Wide LVD SCSI-3, 15,000 RPM, 3.2 ms seek, 8 MB cache, A/V Rated, 3.5" LP, 80 pin SCA interface, 5-year warranty.

THat one is pretty much the fastest mechanical HD in the world



OR
Seagate Cheetah 15K.3, 36.7 GB, Ultra320 SCA-2 LVD SCSI-3, 15,000 RPM, 3.6 ms seek, 8 MB cache, A/V rated, 3.5" LP, 80 pin interface, hot-swap only, 5-year warranty.

Second fastest

Goosemaster just curious but what kind of scores do you think a solid state hard drive would get? I know no one has one because they are extremely expersive i believe.

 

[Boogak]

Maybe they set up a RAM drive and ran the benchmarks off that?

 

[Goosemaster]

Solid State HD do not really excel in sustained transfer rates. THey only get 50MB/s according to the specs I once saw.

Where they excel. Where the fastest SCSI HDs have access times of a little over 3ms(theorectical-not taking latceny into affect) and closer to 4-5ms for ACTUAL, SS drives have access point in single-digit nanoseconds.....I think 7 or 9ns was the number.

VERY big difference.

Assuuming nano is 10^9 (I forget) And assuming milli is 10^4

THere is a MASSIVE difference in access time performance...



Why do you think google uses 'em?😎
