The inexorable march of Moore's law

I think this is the first time I've ever noticed something measured in "terabytes" and thought it too small.

I noticed that the ext3 filesystem has a maximum filesystem size of 16TB. You can buy 1.5 TB hard drives at Fry's today, so you can probably have a 16TB disk array under your desk in the near future.

Fortunately, ext4, which was just marked stable, will support a maximum filesystem size of 1 EB (1024 PB, or 1,048,576 TB). Whew!
