I picked up a Samsung 500GB Portable Solid State Drive T5 for $140.60 at Officeworks yesterday after price matching with Bing Lee's price of $148. Fairly low capacity for the price, but the external HDD seems to be built a bit better than the Seagate I'm currently using.
It's an external SSD, should be at least a few times faster than your Seagate.
