Hmm that means about 200 DVD quality movies .. maybe with space left over for a few thousand songs. And hopefully by 2014 widely deployed 4G cell technology would mean that storage on a portable device wont even be a requirement (you can play files of your desktop HD remotely via stuff like Microsoft Mesh or rent from a provider).

Soon you'll be able to loose terabytes with a single drive failure. Mirroring or parity RAID will probably be highly recommended. Then again, array rebuild time with this size is going to be very long. Probably need RAID 6 in case another drive fails during rebuild.]]>Aug 1st 2008 7:42PMhttp://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/Indeed 2 drives dying in a raid 5 in one day is still possible and damn annoying. Especially when the data had not been properly backed up because "it was on a redundant array".]]>Aug 1st 2008 9:05PMhttp://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/
Only after all of the correction and retries are exhausted will the drive give up and report an error. This spec'd uncorrected (but detected) error rate is usually around 1e-18.

The spec'd uncorrected and undetected (i.e. the drive unknowingly sends incorrect data to the host without notifying it that there is an error) error rate is 1e-24.]]>Aug 1st 2008 9:20PMhttp://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/Aug 1st 2008 10:19PMhttp://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/
We've been hovering quite a while on the 1TB edge, so to speak, to the point where it felt like manufacturers were trying to milk profit from that as long as possible before increasing storage. I was starting to wonder if they'd ever get around to it.]]>Aug 1st 2008 7:46PMhttp://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/Aug 1st 2008 8:10PMhttp://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/Aug 2nd 2008 12:18AMhttp://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/Jan 22nd 2009 5:47PMhttp://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/
And where's my 320Gb iPod Classic? Come to think of that, where's my 160Gb iTouch? And why can't you buy aftermarket 160gb 1.8" drives, did Apple buy the whole world's production?]]>Aug 2nd 2008 4:30AMhttp://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/
Similarly, 160 Gb = 20 GB

You already have these. There's a difference between Bits and Bytes. 1 bit = 8 Bytes. kthx!]]>Aug 2nd 2008 1:41PMhttp://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.youtube.com/watch?v=xb_PyKuI7II]]>Aug 2nd 2008 4:47AMhttp://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/http://www.engadget.com/2008/08/01/hitachi-jacks-perpendicular-recording-density-to-610gb-square/Yes, I'm only a bill.

Found a WD article that says their 160GB platters in 2.5 " drives (320GB Laptop drive) is the same as the 320GB platters in the 3.5" drives (WD6400AAKS) is listed at 250Gb / in^2

So by tht reasoning and math, a 610Gb/s areal density means we can expect a 780 (Call it 750) GB / platter drive in a 3.5" size. Thats means a 2.25 TB desktop drive when they eventually get this technology into a working product. Or a 750GB Laptop drive.

I would expect the newly announced Seagate? 1.5TB drive is 3 x 500GB platters which is using approx 400 Gb / in^2 technology.

So based on that, the jump doesn't seem all that impressive per say. Less than 2 years to go from 250Gb/in^2 to 400Gb/in^2 means we can expect 2TB Desktop drives and 1TB Laptop drives in 2011.]]>Aug 3rd 2008 9:25PM
