Hitachi's new 4TB 7200rpm drive uses four 1TB platters

Edit: updated link to Anand's article since the Storage Review piece got pulled.

Less excited by this drive than I am by the prospect of single platter 1TB HDDs.

i welcome it. now those 4TB drives will start costing $200+ while everyone is now enjoying $99 3TB drives. these should push the prices down a bit more 😀

yep, 3TB sweet spot coming up in the next couple of months.

The best thing about 1TB/platter is the reduced manufacturing costs for the same capacity and the higher performance. Given that we're getting around 150MB/s sequential 4KB reads with 750GB/platter we should be seeing around 175-180MB/s*. :thumbsup:

As always, though, random reads/writes will improve little. This is where SSDs make the most pronounced difference. :thumbsdown:

*As long as spindle speed is 7200RPM, of course.

i didn't even think about that aspect!

I hit the nail roundly on the head.

Can't view the page for some reason, but good news. Don't care for 7200rpm, but this means 5400-5900rpm version are not too far behind. I'm all for cheap storage!

Yes, more space to backup, but you also lose 3T or more when hd goes kaput. I guess backup of your backup is even more important as hd size goes up.

This argument has been bandied forever, waaay back to even the first 1GB drives. ZOMG 1,000 floppies!

That said, I am a little leery of >2TB drives. Unfortunately, that means my fileserver is limited to 30TB for the moment.

as far as the topic of reliability goes - i wonder if it's possible to find out if it's possible to design drives so that instead of failing outright, you get bad sectors instead? i've never had a WD drive fail outright, just bad sectors which is why i stick with them.

hmm, I get an access denied error while clicking on link. Must I register, or was the article pulled?

I must say, I am curious as to how the performance is! I assume this is Sata 6G?

Updated the link. I'm sure performance will be better than what we've seen before from standard 7200rpm drives. LWA's logic above makes sense to me.

I'm always leery of 4+ platter HDDs, so I'm hesitant to use 3TB drives right now. With 1TB platters, that concern will vanish.

Well, my hesistance is for a different reason. I don't mind 4+ platter HDDs (still have more than 10 1st gen, 5-platter Hitachi 1TBs humming along 24/7/365, have been for the last couplf of years). It's more the issues with >2.2TB drive support.
