Deskstar 75GXP is it for 66MB or 100MB tranfer rate boards?

I'm getting a msi k7t pro with a 66MB IDE connetion and all the deskstar HD's say ATA/100 does this mean that it's for 100MB boards?

it'll work with an ATA66 board, but it's one of the first drives to have ATA100 support, and will not move data as fast with an ATA66 board than with an ATA100 board

<< and will not move data as fast with an ATA66 board than with an ATA100 board >>



Thats not true at all, ide drives can barely sustain 30-35 megs/second transfer rates. If you think that an ata100 drive will be faster on a ata100 controller compared to a ata66 controller, you are dead wrong.

That's only true from the cache in the drive (a whopping 2MB) transfering to main memory. That's the only time you'll see 100MB/s

I think an IBM 75GXP can break 33MB/s going disk platter to host, so if you had two of them on a single ATA66 channel you might lose 4MB/s or something of transfer rate.

But a Single 75GXP will come no where near maxing out an ATA66 channel by itself.

Two 75GXPs in RAID-0 on an ATA66 RAID controller can max out the interface.
It's weird seeing the WinBench99 Transfer Rate test with the top part of it as flat as can be. heh

75GXP hits like 37mb/sec tops. That's only at the beginning of the drive too. ATA66 improves it's overall performance only about 5-10%, ata100 is pointless. 2 Drives in RAID0 shouldn't max out ata66. More to the point if you're gonna have a RAID, what are you doing with 2 drives on one chanel.

I understand what habby and noriaki are saying, but I did not explain myself thorougly. I was thinking of a friend who had a RAID array setup with two Deskstars, and could get better throughput OVER 66MB/s. Sorry if I caused any confusion. I was aware that the ATA66 would not be maxed out, therefore the ATA100 would make no difference with only 1 drive attached.

How would you setup a RAID 0 array given two 75GXP drives and a motherboard with RAID on it like the KT7? I'm not too familiar with how RAID is put together, and is this the best way to max out speed and performance given by the 75GXP drives?

 

[Doomguy]

Burst speed wont really help your performance at all.

Setting up RAID is easier than installing Windows, if that's a fair comparison. It's really simple, and, just a quick note, you will NOT max out the ATA100 bandwith. It's near impossible, if not just plain impossible.
