Before we continue with the results from the noise production measurements let's start by mentioning that the harddisks were all tested as-is, so without any settings changed in the acoustic management some of them offered.

Re: WD1200JB
Yeah, we were suprised by these numbers too and contacted Western Digital that sent us two new harddisks, unfortunately these performed identical and we have yet to find a cause. For now we'd just not recommend these disks wholeheartedly as the numbers seem a little off, and as pointed out by others might not be a good indication of their performance, but are accurate as per our findings.
Strange thing is the fact that both the 1200BB and 1200JB experienced the same problem, whereas the 800BB and 800JB were not affected. You'd think that if one disk is defective the other would still do well, but both 120GB WD disks performed less than expected. From what we've learnt both the 80 and 120GB versions of these 7200-rpm WD disks use the same control hardware, which makes the PCB mounted underneath virtually identical. The only difference would be a different firmware.
Although we could've pulled these two disks from the article or postponed the article to a later date we felt we did everything possible to setup a proper testbed and testing environment. If the 1200BB and 1200JB weren't able to show their full potential under these conditions whereas the other disks were able to then whose to blame? We'll be sure to update the article when we get new information from WD regarding this or do a new roundup (as there's a whole set of new disks on the horizon) in a few weeks that might shed a different light on things. For now we'll just stick with the results we've measured and cannot recommend the 1200JB or 1200BB.
Kind regards,

Er is op dit moment blijkbaar nog geen logische verklaring, wordt vervolgd (hoop ik)

Boasting the ultimate in ATA capacity and performance, the WD1200JB rivals today's top SCSI drives when it comes to single-user desktop performance.
With desktop performance and capacity vastly superior to the competition as well as a surprisingly low operating temperature, the Caviar WD1200JB reaffirms Western Digital's preeminence in the IDE desktop performance segment. In fact, for desktop usage, the JB bests all 10k RPM drives save only Maxtor's Atlas 10k III.

So, what can we deduce from the tests?
Firstly, we have to repeat the phrase said in the introduction:
WD800JB is as fast as both WD1000JB and WD1200JB, but of smaller storage capacity and better value.
It should also be acknowledged that JB drives from Western Digital have no absolute superiority, just like there's no absolute perfection…
Every HDD reviewed here has its advantages and shortcomings, and I hope the growing amount of tests allowed us to look at HDD performance from a new angle.
The analysis of the results shown by the WD drives of different capacity uncovered a certain anomaly. WD 1000BB was faster in some tests than the JB HDDs! As you may guess, I was rather intrigued and carried out a little investigation. A few drives (unfortunately, not all) were still in my possession and I wrote down the firmware version numbers from them:
WD1000BB-00CAA0: 08 Feb, 2002 DCM: HSEACV2CA firmware 16.06V16
WD800JB-00CRA1: 11 Apr, 2002 DCM: HSFHCV2CA firmware 17.07W17
WD1000JB-32CWE0: 31 Jan, 2002 DCM: HSEBBT2CH firmware 22.04A22
WD1200JB-75CRA0: 01 Feb, 2002 DCM: HSEANA2CA firmware 16.06V16
Look at the firmware version of WD1000BB. It's the same as WD1200JB has! It turns out that the same firmware is used in both BB and JB hard disk drive families. That's why these HDDs behave much alike in the benchmarks. Well, from now on we'll have to pay attention to the HDD firmware version as well, it seems...
Ben toch wel eens benieuwd welke firmware Sander heeft gebruikt bij zijn tests?
En of de resultaten dan zo anders zouden kunnen zijn.
