Following the introduction of  the Caviar Black series of SATA 6Gbps drives, Western Digital has expanded support for the new speedy standard to cheaper and smaller Caviar Blue drives.

The new Caviar Blue series will be available in 250, 320, 500, 750 and 1000GB capacities, but it will feature less cache than the Black series. The 250, 320 and 500GB models feature 16MB of cache and prices start at just €33, making them the cheapest SATA 6Gbps drives on the market.

The 750GB and 1000GB models cost €45 and €53 respectively and they’re significantly cheaper than comparable Caviar Black models.

However, it’s worth noting that SATA 6Gbps support is rather pointless in low end drives such as the Caviar Blue series, but at least it sounds nice and marketing blokes will appreciate it.
