Re: Best brand of IDE hard drive
Hi, somemore, During a discussion with the boss, the question came up about 5400 speed vs 7200 speed. We have a couple of Power Macs, a bunch of 580 Quads, and 100+ PCs ranging from 200 Mhz to 1 GHz+. Is there any reason not to purchase 7200 speed hard drives?

Heat is a legitimate concern, though IDE drives don't tend to heat up as much as SCSI drives do. Knowing the tightly packed nature of the 580s and 630s, I wouldn't put a 7200 RPM hard disk in them. -- the pickle FAQ http://macfaq.org/index.shtml _ -- Quadlist is sponsored by http://lowendmac.com/ and...

So even at the same spindle speed they may have a more powerful head positioning drive which makes for more heat. Don't forget that the SCSI controller only does 5MB/s buffer-to-host, and the IDE controller, IIRC, does PIO mode 2 at best, which would be ~8MB/s buffer-to-host. IMHO, 7200RPM drives would be a waste of money on these machines. You might see the 5-10% difference on an ATA-4,5 machine, but that's with a controller that can do 66-100MB/s buffer-to-host (theoretical max, of course). I have found that older SCSI drives (this doesn't apply to narrow drives, since they were designed more with desktop usage in mind) usually have a shorter useful life than IDE drives. This relates directly to their intended use. Wide SCSI drives have usually been used in a server setting, i.e. they have been used in disk-intensive applications for long periods of time. IMHO, that is usually why they produce more heat: they are normally past their useful life. I am speaking of used drives, so if they are new, please disregard. So, for SCSI drives, excuse the cliche, you are stuck between a rock and a hard place. Finding larger capacity narrow drives is difficult, and using wide drives with a converter will most likely result in a higher failure rate. As for IDE, I think you would be best suited purchasing 5400RPM, ATA-33 (UDMA-2) drives, somewhere between 5-8GB. The Western Digital 16400 series is one of the most popular I've seen. I also use Seagate's ST364xxA Medalist series. Please don't forget that on 68k machines you cannot boot from HFS+ partitions. So your boot partition cannot be larger than 2GB. But that doesn't mean you can't format the rest of it in HFS+, as long as you are using MacOS 8! _ Add photos to your messages with MSN 8.
