WinBench 99 - Transfer Rate Test
We ran WinBench 99's Disk Transfer Rate Test to get a better measure of just how well the transfer rates are over the course of the entire disk. The Disk Transfer Rate test reads from the media in a linear fashion from the beginning (outer tracks) to the end (inner tracks) to find the actual transfer rates of every track on the platter. The numbers below represent the speed at which the benchmark started and ended.WinBench 99's Transfer Rate test began reading the 7200.8 at 70.5MBs/sec. As the drive heads moved closer to the inside of the media, the transfer rates decreased, but not as much as those on the other drives. The test ended with a 70.3MBs/sec transfer rate, which is much higher than the ending rate of other drives. A 200KB/sec drop in transfer rate from start to finish is obviously much better than a 10MB/sec decrease.

mjz5: With our nForce4 platform there is an option under the drive controllers options tab called "Enable command queuing". By checking this option and restarting the system, command queuing will be enabled. Some boards, however, enable NCQ/TCQ by default through the BIOS. You may want to check with your motherboard manual on that.Take care,

Nighteye2 has a good question. How does NCQ work with RAID arrays? Is it better, worse???How would I know if TCQ is enabled on my 74 raptor?

#21 LOL --- you wouldnt want that space anyways even if it was there.... its cant be guaranteed reliable so would you trust 100gb's of your drive that could die at any moment???quorm - Wednesday, April 20, 2005 - link
I have one of the 300gb 7200.8 drives. It's mentioned in the article that all of the 7200.8 drives use a 3x133gb platter configuration. I was wondering if there is any hack to allow access to the remaining 100gb of disk space. Anyone?AtaStrumf - Wednesday, April 20, 2005 - link
Hey, where did all the WD drives (apart from Raptor obviously) go??? I can get a 200 GB PATA model pretty cheap, so I'm seriously considering it. Any advice anyone?n7 - Wednesday, April 20, 2005 - link
Thanx for the review guys :)flatblastard: I'd agree.
The Raptors may not win all the benches, but i find they feel so much snappier than my other 7200RPM drives.
I certainly wouldn't mind adding a 400 Gb Seagate to my collection though :)

Can you guys post a UT2004 for load time graph please.flatblastard - Wednesday, April 20, 2005 - link
I'm using the raptor for my OS, and the 250GB seagate 7200.8 for everything else. I really can't tell which one is faster at loading games...but the raptor is MUCH quicker loading anything else.Icehawk - Wednesday, April 20, 2005 - link
Where were the heavier real-world multi-tasking tests like in the Intel DC previews? In those articles it appeared that NCQ offered some performance boost in heavy I/O situations - here it seems to offer zero benefit.Houdani - Wednesday, April 20, 2005 - link
I dunno. Neither the Seagate nor the Maxtor NCQ drive really impressed me. They didn't stand out from the peleton. For most performance needs, I'd have to give the yellow jersey to the Raptor, although the idle heat is a noteworthy ding.For extra capacity one of the larger models would be prudent, but for a primary drive the Raptor is fairly impressive.
