Comes in Q2 2013, 500 series
Intel is about to launch ist 525 series of 25nm MLC drives in Q4 2012 and the successor of the 520 series won’t be coming in 480GB version. We can only assume that the price of the 480GB unit was too steep for many.
The 525 series cone in 30GB, 120GB, 180GB as well as 240GB capacities. You will notice that even the 60GB is missing from the list but if you really exclusively want 60GB, Intel hopes you will get a 60GB or 80GB unit from 500 or 300 series. The successor to the 525 series currently codenamed under Sierra Star is now scheduled for Q2 2013 announcement. Other than it comes with Opal hardware encryption and supports 6Gb/s interface we know very little about it.
We do know that this new 500 family member is based on the 20nm MLC manufacturing process with capacities to be disclosed at later date. We cannot really say Intel is the best player in SSD market as it’s usually more expensive than anyone else, but it is an alternative for some consumers.
