Seagate plans to triple areal densities within two years

At the IDEMA DISKON show in Santa Clara, California, Seagate demonstrated a magnetic recording device with a whopping 421 Gbits per square inch density.  To put that in perspective, the company recently announced 160GB 5400.3 2.5" perpendicular notebook drives that have an areal density of 135 Gbits per square inch. Toshiba, the current commercial density leaders, recently demonstrated 2.5" hard drives with areal densities of 188 Gbits per square inch.

Seagate CEO Bill Watkins claims "Breakthroughs in areal density are enabling the digital revolution and clearly indicate that hard drives can sustain their advantage to meet the world's insatiable demand for storage across a wide range of market segments."

According to the press release put out by Seagate, the company claims a 1.8" disk drive produced on the same 421 Gbits per square inch technology would result in a 275GB hard drive. 2.5" drives on the density would level out around 500GB, and fully fledged 3.5" hard drives would be able to house a density of 2.5 terabytes.  Perhaps even more exciting is that Seagate "anticipates that solutions at these density levels could begin to emerge in 2009."

The leap to such densities would result in a three-fold increase of current areal densities. However, Seagate isn't alone in this race.  Earlier this year Hitachi put out a press release claiming we would see 1TB holographic drives from the company before the end of the year.  However, both companies use Komag as the primary supplier of their high density platters -- and it should not be a surprise if we see 1TB hard disk drives as well.

I think partitioning is more trouble than it's worth, especially for a separate data drive. Just the fact that it's a separate drive from the system (boot) drive is often enough separatation. I don't see the point splitting a 300GB data drive into three pieces. I'm more likely to stripe drives. I don't think it takes terribly long to defragment a drive unless it is too full or you've neglected it for a year.

Keyword here is "drive too full". Dunno bout you but the whole reason I would want 10 TB of staorage is because Im already seeing limits on my current storage situ, and one can never have too much storage. I have some 60 gigs of music files, and defragging that drive is terrible, I only do it every 3 mo, but that because its takes long enough and Im not too upset if it take a few ms more to access a certain album. Nonetheless, partioning works, and the only trouble it takes is a good three minutes and a fresh drive.

Unless you are deleting music files and adding them once you defrag reading the file won't move them. Get diskeeper and let it defrag in the background or at scheduled times over night.
