With what appears to be a dwindling market supply of ATA drives here in NZ (and elsewhere?), and the unlikely event of my owning an updated Mac in the near future, I'm thinking I ought to make a purchase sooner rather than later. These are what I'm considering:
• Hitachi Deskstar P7K500 Hard Disk Drive, 250GB, 7200rpm, 8MB Cache, *ATA-7/133*
• Seagate Barracuda 7200.10 ST3250620A 16MB 250GB
• Seagate Barracuda 7200.10 ST3250820A 8MB 250GB.
Could someone please explain:
1. the *data* of the Hitachi - what does the 7/133 mean?
2. The potential advantage in the Seagate of a 16 Mb cache [there's very little price difference.]
