Hello All, I'm considering upgrading my i-opener hard drive to the 20 Gig 5400RPM Hitachi 40GNX with 8mb Cache (IC25N020ATCS05). I just bought a 120 Gig Maxtor with 8mb cache for my desktop and it flys, however my desktop fully supports the drive. I currently have an old 2Gig 4200RPM drive in my I-opener. I want to know if anyone has tried a hard disk with 8mb cache in their i-opener and what kind of performance increase that gives. Here are the rest of my I-Opener specs:
V3 I-Opener
5.40A Bios
128MB RAM
Kingston TurboChip 400Mhz (AMD K6)
Windows 98lite With IE 5.5
Thanks,
--Rick

I believe that the cache on a harddrive is completely transparent to the system accessing it. First the drive lets the system know what protocols it can follow and what it's geometry is (both are optional and can be entered manually into the BIOS, but the system must know these to boot). From that point on, all devices look the same; it is just a matter of how high the PC in question can "count" to calculate where on a disk a given file might be (BIOS + OS limitation of HDD size). I know of no system limitations that have to do with cache size, only hard drive size as presented by cyl x sect x heads. The cache merely keeps the last used in memory instead of going to the platters; an 8M can hold a larger amount of recent reads or writes, but still has to present the info as if it came from the disk itself.
