Data storage is a different animal.
I won't say that data storage is completely immune from the erratic behavior of the Nasdaq, but positive numbers like strong earnings and profit growth make these companies unique. The data storage market will likely see explosive growth in the coming quarters. You might as well get in now while it's still a bargain. In a market that's going to be this big, there's room for both the big players and their smaller competition. There will be no shakeout in this sector.
