HPT366 controller slower than IDE
HPT366 controller slower than IDE
I have measured the speed of my BP6 motherboard with AIDA32, and I found that the speed of the disk (QUANTUM FIREBALL CR4) is substantially slower, if I connect it to the HPT366 controller. Can anyone tell me, why?

Could be several things.
Drive not in UDMA mode 4. Not using a true ATA/66 cable (80-pin). Older HPT366 driver or BIOS. When the HPT366 BIOS screen opens; what's BIOS version and does UDMA 4 show at the right end of the hard drive statement. What HPT366 driver revision are you using?
I did some benchmarks a few years back on the same thing.
I found negligible difference between the two interfaces, using the correct cables and transfer mode.
I never use the HPT as I found it to be non-advantageous and possibly damaging to disk drives.

The drive is UDMA 4 mode, the cable is a true ATA/66 cable. HTP366 BIOS version is 1.22, driver is WinXP 1.30.hyperspace wrote:Welcome to BP6.Com, hg !hg wrote:I have measured the speed of my BP6 motherboard with AIDA32, and I found that the speed of the disk (QUANTUM FIREBALL CR4) is substantially slower, if I connect it to the HPT366 controller.

What Fireball ist that? Older type? Capacity?
For me, the HPT366 has always been much faster, at least when it came to disk transfer rates. For my old Fujitsu 40GB, 25 MB/s was the limit on the standard IDE, while it reached 40 MB/s on the HPT366.
