Storage has always been a major limitation of SSDs or solid state drives. However each generation of NAND improvement has contributed to the steady increase of SSD capacities. The question has always been how much storage can you fit inside a 2.5″ drive since that is the conventional form factor for most enterprise drives. SanDisk has a game changing answer in its new 2.5″ 4TB SSD. The SanDisk Optimus MAX SAS SSds have been designed to take the place of existing 10k and 15k RPM spinning 2.5″ hard disk drives, and it does that very well without compromising on either performance or capacity.
