SanDisk has announced a new 4TB flash drive, double the capacity of the biggest solid-state drive available today.
The 4TB Optimus MAX – which sounds like the big bad brother of an Optimus Prime toy – follows the 2TB Optimus Eco, a technology SanDisk acquired when it bought SMART Storage.
The new SSD can take three full drive writes a day for five years. It has a SAS interface and its basic performance numbers are as follows (with previous Eco numbers in brackets for comparison):
- 75,000 random read IOPS (Optimus Eco: 100,000)
- 15,000 random write IOPS (Optimus Eco: 45,000)
- 400MB/sec sequential read and write (Optimus Eco: 500MB/sec)
Why is the MAX slower than the Eco? SanDisk says the Eco uses 19nm MLC flash while the MAX is made from 19nm eMLC, a better grade of flash but not one that we usually think of as slower – the MAX random write speed being a third of the Eco's.
