Wow. Seagate just announced the world’s first 3 TB drive. Called the Seagate FreeAgent GoFlex Desk, it’s big enough to hold about 1,000 full-length HD movies or 1 million digital photos or songs.
It is also twice the size of the Seagate drives we used in the Backblaze Storage Pod when we published the design in September. Switching to the 3 TB hard drives in our storage pods would mean one Backblaze Storage Pod would hold 135 TB of data: 45,000 full-length HD movies or 45 million digital photos or songs. That is one monster collection of media.
The Seagate 3 TB hard drives are only available for external use only at this point, so we can’t actually put them into our storage pods – but we’re keeping an eye out. If you want one one of these drives for yourself, they’re $250 at Seagate. (Note that you need to be using a 64-bit OS to take advantage of all the space.)
For my estimates, I’m assuming an HD movie is 3 GB (as Hot Tub Time Machine on iTunes is when I just looked at it a second ago) and a photo or song is 3 MB (as they are with a 5 megapixel camera and downloaded from iTunes respectively.)
