How do maxtors handle 41MHz PCI speed?

[kami]

See a good deal on a 20GB 7200rpm ata/66 maxtor. I'm guessing it's a DiamondMax or whatever they are called but I'm not 100% sure. Anyone know if they have problems with 41MHz PCI speed?

Are you gonna run 164MHz front side bus?

I have no problems running mine at various different FSBs between 100 and 133.

No I have a computer (not mine) that uses 83mhz bus and needs a new hard drive. Just need to know if they have any problems with 41MHz PCI.

 

[LXi]

No, I ran at 124MHz FSB for quite a while, which results a 41MHz PCI bus, no problems at all. Make sure the Maxtor is a new model though.

cool, thanks.

mine does 83 mhz bus flawlessly

I have a Maxtor Diamondmax 40+ that will not run at 34.5 mHz on a Asus P3V4X. It is a royal pain since I want to overclock my system a little more. I have a P3 550E that will run at 733 mHz with the defalt voltage. I tested the system by running the FSB and memory at 100 mHz and then slowly increasing the speed until the system crapped out. I don't know if the motherboard HD controller has any effect. I do know that this system will not tolerate any non-standard PCI speeds.

And you blame that on your hard drive? There can be a variety of factors causing systems to dislike funny front side buses. And how can you be so certain that it's your hard drive? Anyone of your PCI devices might be the cause of this problem, the AGP video card is also very sensative to non-standard front side buses. There is no way to conclude that it's Maxtor's fault unless you've tried another hard drive brand and it works at FSBs that the Maxtor refuse to.

Well right now on the system there is a IBM 22GXP 13.5gig and a Fujitsu 4.3gig dma/33. The Fujitsu has some trouble working sometimes unless I turn DMA off. The IBM works fine...IBMs are great for high PCI speeds.

Just hoping maxtors are too

Last month I fried a brand new 30 Gb Maxtor 5400 rpm within an hour, running at 38.3 MHz (FSB 115). After that it wouldn't even work at 33 MHz. This is on an ultra stable BX system.

Then a few weeks later, I corrupted my old Quantum 10 Gb drive at 38.3. However, the drive is fine, and still runs great at 37.3 MHz, with no bad sectors after reformatting.

My IBM 34 GXP 20 Gb drive was perfectly fine throughout all of this. I think I'm going to stick with 37.5 MHz or less from now on. I may drop down to 36.7 actually. (That way I can drop my CPU voltage too.)

I note that the guys over at www.storagereview.com on the forum are very reluctant to go above 37.5 with any drive, with many of them refusing to go over 35 MHz. Now I agree with the 37.5 number. Then again, most of them aren't hardcore overclockers like us AnandTechers. 😉

Consider yourself warned.

Nearly all hard drives run at 41.5Mhz PCI just fine, as long as you don't enable UDMA. However, this completely kills drive's performance. If you want a HDD which handles 41.5MHz w/ UDMA I suggest you look at Quantum or new IBM (GXP, not GP) drives.

And yes, Maxtor drives - at least the 5400rpm models - are the worst to handle overclocking. I also have first-hand bad experiences with 5400rpm Seagate Medallist drives.
