When they get down to 3 platters, sure. WD and Seagate use 4.

Forgive me for demonstrating my ignorance, but why does the number of platters make so much of a difference?

Seems like a pretty decent deal for 2 TBs. I have not had any issues with Hitachi drives over the years.

Too bad you can't RAID the platter.

for starters, more platters means more weight to have to spin which means longer spin-up times which translates into longer seek times.

Required more power, more heat exhausted. More heads used to read --> more prone to errors/damage. Less dense-->slower compared to fewer platters HDDs (comparable class ie 7200rpm). To name a few. Though if you're using these to store movies, music & pix then the points above become moot.

Love the price, don't love finding zero reviews at the usual places.

The points #5 made "above" are still relevant, as they lead to earlier failure and more noise which is never worthwhile when you have other options at similar price-point.

Even with WD or Seagate, you're better off sticking to 2 or 3 platter drives, especially when you're not getting a big price break for another platter stuffed in, when it costs close to the same for two entire 1TB drives instead... unless you're on some mad quest for max TB in a small chassis then what can I say except refurb some old system and stuff them into it, people are now abandoning SATA capable systems that only need a new PSU or dust cleaned out... if you're too cheap to spring for eSATA enclosures.
