10,000rpm IDE Hard Drives Coming
By Remy Davison, Insanely Great Mac
February 7th 2003
New WD drives close the gap with SCSI.
MacBidouille reports that Western Digital will announce 10,000rpm serial ATA hard
drives on February 11.
Specifications cited are:
- 10,000rpm
- 8MB buffer
- 5 year warranty
- MTBF: 1.2 million hours
Hard drive bandwidth is the main bottleneck holding back performance at present. CPU
bandwidth can easily handle the fastest hard drives (such as 15,000rpm LVD SCSI, which
can deliver sustained speeds of up 160MB/ps, well in excess of any IDE drive currently
on the market.
Analysis: On a price:performance basis, IDE is catching up, although there are no
figures on the actual performance of the 10,000rpm drives. But these drives should
work well as FireWire externals as well, as 7,200rpm/big cache drives demonstrate
markedly better performance than 5,400rpm drives.
But, like MacBidouille, we wonder how WD managed to simulate those MTBF-137-years
tests. We don't know. We're not hard drive experts!
