As i browse online PC parts reseller website, I noticed that the prices of HDD doubled. I refer to my downloaded copy of their SRP price list last 3 months and indeed prices have gone way up.

Here's the main reference:

Now, my plan to buy a 1tb 2.5" hdd for my bnew PS3 will be put on hold for the moment.
