Real World Tests - Multitasking Performance

To provide a real world example of multitasking, we run Outlook and import 450MB of emails into an account. We then measure the time that it takes our benchmarking utility to zip a single 300MB file. To compare our results, we calculate the difference between the multitasked process and the single task file zip process.

Outlook + Zip a 300MB File Within Drive
Multitasked File Zip Only % Difference
Seagate 7200.9 500GB, 16MB, 3.0GB/sec 69.215 59.707 15.9%
Hitachi 7K500, 16MB, 3.0GB/sec 70.512 62.156 13.4%
Western Digital WD1600JS 69.25 61.443 12.7%


The WD4000YR looks like it performs the best out of the three while running multiple tasks but only by a second or two. It zips a 300MB file while importing emails in Outlook about 12.7% slower than just performing the file zip operation on its own while the Hitachi and Seagate drives handle this task 13.4-15.9% slower.

    Kinda reminds me of AGP... or PCI... or pretty much most of the standards these days getting replaced by "better faster must have!" standards that cost the end user money and offer no real improvement in performance.


    I can understand mentioning AGP, but PCI? You gotta be kidding me... that bus is such a bottleneck. You dont even have to run PCI cards to find out, just stress all the on-board stuff on a feature rich mobo and you'll notice it too.

    Which explains the rush from the mfts to get PCI-Ex cards out the door. :p Really, the only 2 cards that i can see benifiting from the PCI Express bus are high level RAID cards and gigabit ethernet... both of which are being fully integrated into southbridges anyway.

    You said AGP and PCI, not AGP and PCIe. Obviously there isn't a lot of difference between the latter, but there is quite a bit of difference between the former.

    They are integrated into southbridge and still utilize the PCI bus mostly. PCI bus aint only the slot you see on your mobo, you know..

    High level RAID? A single PATA drive has an interface speed identical to that of the PCI bus (133MB/s) these days, all by itself. And then there's SATA with 150MB/s and 300MB/s interface speeds now. Not to mention the PCI bus is usually shared with a multitude of devices, all wanting some bandwidth.

    It seems anomalous that the Western Digital Raptor 10000RPM drive is sooo much slower in the Doom 3 level load test compared to all the other drives. It sticks out like a sore thumb. It doesn't make sense because it had been dominating the other tests...
