Apple IDE Cannot Access Beyond 137GB

An anonymous reader writes: "iMacLinux reported on a PenguinPPC story about Apple hardware being unable to address more than 137GB of space on IDE drives. The Apple computers only have ATA-66, which can only address 28 bits, while ATA-100/133 can address 48 bits. Solutions include using a PCI controller, FireWire or SCSI."

Apple: "All these machines include FireWire ports that operate at up to 400 megabits per second"

my accent

Firewire has 50 Megabytes per second.

ATA 66 has 66 Megabytes per second.
ATA 133 has 133 Megabytes per second.
SCSI 160 has 160 Megabytes per second.
USB 2.0 has 60 Megabytes per second.

firewire drives will not save apple, they are slow too.

Current ATA drives peak at full ATA spec due to their huge caches. Their throughput on an ATA 100 bus is just under 50 megabytes per second meaning current drives outperform the firewire spec.

Can't exactly daisy chain firewire devices when ONE uses the spec's entire bandwidth.

So much for Apple being the DV platform of choice.

Well Put

Athlon XP @ 1826/166fsb is the first computer I have ever owned (including a 733 G4/512k) that can scroll through a PDF with no draw in lag. None. It looks just like scrolling through a simpletext document. You can actually read the PDF without printing it. If speed isn't an issue, why does apple release faster models? Migrateing to commodity PC hardware is like breathing easy after years of suffocation: I didn't even know I was suffocating. Apple coddles users into thinking thay have a high performance machine the way VW coddles new beetle owners. It's fast and sporty and shiny and glossy and will get it's doors blown off by the first old rx-7 that crosses it's path. What is wrong with a cray? Why do you think I water cool? Just surfing? Hardly. I can actually rip a DVD to mpeg4 in real time. Apple cannot even play the divx codec.

I'm not a PC fanboy. I work with Apples for a living. I respect them as far as user experience goes but never will I make the mistake of assuming that an Apple has any speed at all. Quadra 650? Put netBSD on that thing. you might learn what memory management and multitasking are. I'm sure you put a lot of love into some old macs but it is time to move out of the world of education and into a real machine. The world loves an underdog but they are beaten -- often
