Even with the cheap picosecond lasers existing today, a laser hard drive could reach a phenomenal speed of about 1 TBits/s. In comparison, a top of the line hard drive today can reach a data transfer rate of about 1GBits/s, and advanced solid state flash drives can reach about 2-3 times that speed. In the more distant future femtosecond based laser drives could potentially reach unimaginable speeds of up to 100TBits/s and beyond.

so RAM will become obsolete

You wish!
No, but it's interesting that reading and writing to disk will be faster than reading and writing to RAM.
RAM today has an average of 10Gbit/s transfer speed. Picolaser harddrive 1Tbit - 100Tbit.
SSD about 3 Gb. Conventional harddrive about 1Gbit.

yes... so unless we get laser or microwave RAM it will get obsolete as too slow

When transfer speed reaches 1Tbit/s (and possibly later 100Tbit/s) I wonder then how important indexes will be?
And performance adjustments?

Well, backups will still be needed. I hope!

software always expands to fill up any perf gains introduced by hardware. I imagine this would continue to be true even with such fast drives.

Are you talking about .Net version 4

If tablescans, and lack of indexes (indeces?) become irrelevant thanks to hardware advances, we will more than make up for the lost time performance tuning in resolving data discrepancies, and update anomalies in the horrid designs that are certain to follow in the advance's wake.
