First about the seller: WS Retail: Prompt service as usual. Since, Flipkart started allowing 3rd party sellers, best way to make sure you still get the old flipkart experience (which was the main reason flipkart got popular - prompt delivery, perfect packaging etc) is to check for the seller : WS Retail. Now about the product: Build: It is perfectly named - a passport sized HDD, it can easily fit in your pocket. Material is cheap plastic, not at all durable. 1 drop & I think it is done for. Still looks sleek and has a minimalistic design. Performance: I am getting around 50-60 mbps transfer speed consistently. But as fas as I know the speed depends on the HDD as well as your system configuration. My guess would be it would give even higher transfer speeds if you had a high config PC. So, overall a good product. 50-60 mbps is not slow but I won't call it fast.
