In order to expand the RE series (or what used to be called the RAID Edition), Western Digital is now adding a massively endowed 4TB SKU. Not only will this offer a solution perfectly for the “Big Data” needs of tomorrow but a sequential data rate of 171 MB/s over a SATA 6Gbps interface actually makes it one of the faster 7200PRM drives on the market. For those outside of its intended market, just be prepared to give up about $425 to own one of the SATA models. The SAS version meanwhile goes for just under $500.
Finally getting to the 4TB high water mark did take a while though. Last year we saw the advent of ultra dense 1TB per platter hard drives and it seemed like 4TB – or even larger – 3.5” hard drives were just over the horizon. It really was a great time to be a storage enthusiast. Then the great flood of 2011 hit and literally overnight, the onward march towards bigger, faster and better hard drives came to a stumbling halt.
