If you need masses of storage but like your laptop's performance super-fast, then this new SSD may scratch your itch. With 6TB of storage, this is the world's largest capacity 2.5-inch SSD (for now).
The Fixstars SSD measures just 9.5mm in thickness and offers read speeds of up to 540MB/s and write speeds of up to 520MB/s. Larger capacity SSDs are available, but not in this form factor. Prices aren't yet available, but given a 1TB version costs $US1000, expect to have to dig deep into your wallet. [Fixstars via PhysOrg]
