anyone know what the max data speed for IDE is off the top of their heads?

[BrynF_UK]

the thread title says it all really, but anyone know the maximum data transfers speed for IDE is i.e. between a mobo and a hdd? by speed i mean Mb/s or what have you.

thanks.

I believe its ~133MB/sec

 

[A True Folder]

ATA-6 Ultra-ATA/100, 100MBytes/sec,16 bit data width 40 pin data connector/80 pin cable, with the additional 40 new pins being Ground. Using PIO Modes 0, 1, 2, 3, or 4 and Multiword DMA modes 1 and 2 and Ultra DMA modes 0, 1, 2, 3, 4 and 5. 100MBps Transfer speed = [(1/40nS) x 2 bytes x 2]. Where 40nS cycle time is 2 clock periods at 20nS each. The ATA-6 standard was released in 2002.

ATA-7 Ultra-ATA/133, 133MBytes/sec,16 bit data width 40 pin data connector/80 pin cable, with the additional 40 new pins being Ground. Using PIO Modes 0, 1, 2, 3, or 4 and Multiword DMA modes 0, 1 and 2 and Ultra DMA modes 0, 1, 2, 3, 4, 5 and 6. 133MBps Transfer speed = [(1/30nS) x 2 bytes x 2]. Where 30nS cycle time is 2 clock periods at 15nS each. The ATA-7 standard was released in 2005. With the introduction of Serial ATA, this is the last expected update of the IDE [PATA] bus. SATA is faster, and requires a smaller cable, which means better air flow in the Case.

ATA-33 is 33MBPS, ATA-66 is 66MBPS, ATA-100 is 100MBPS, ATA-133 is 133MBPS, ATA-150 is 150MBPS.
SATA 1.5GBPS (Gigabits, not bytes) and SATA 3.0GBPS are actually faster, but they have the speed of around 150MBPS and 300MBPS. It feels like that.

The trouble is that hard drives cannot read at 300MBps so it is not actually used to full potential
