However, this can cause problems down the line SSDs store data in a completely different way to spinning hard disks. SSD manufacturers now support Apple computers / OS X.SSD reliability has dramatically increased over the last few years.2TB+ capacity SSDs in a 2.5' form factor are now available (from summer 2016) which is bigger than 2.5' hard disk capacities.Prices have come right down/are now affordable and the £$ per GB ratio has become reasonable.SSDs are lighter, use less energy (great for laptops) and more durable than spinning hard drives.SSDs are much faster than traditional spinning hard drives - even an SSD on a SATA 1 (1.5Gbps) connection will be faster than a hard disk.
