For sure, the new Seagate 7200.12 series of HDD is significantly faster than its is predecessor, the 7200.11. Upgrading is just worthy and will boost the performance of your PC. You can easily expect a faster reading by 17MB/sec, while writing writing will be even faster. In addition, the 7200.11 series, is less noisy and produces less heat, even at full load.
The 500GB model (ST3500418AS) we tested today retails for about €52 (including VAT) and it is backed by a 5-year warranty! It is obvious that this product offers a great value for its money and it is one of the best hard disk drives available at this price range. Let's hope that it will not suffer from any reliability issues seen with the previous 7200.11 series (1~1.5TB).
