The biggest advantage of SSDs is durability. Hard disks have plates that move during read/write process. That means every time you save or delete a data, the hard disk will move. SSDs on the other hand, will do the same process without any movement.
Another advantage of SSDs is the longer battery life it can offer to mobile devices. There are currently laptops and MIDs (Mobile Internet Devices) which come with SSDs and they work longer on the road compared to hard disks. The advantage of no-movable parts is also used to add more life to mobile devices.
But SSDs are not necessarily the ideal upgrade for everyone. Its main selling point is durability and better battery life but it's still a very expensive technology. A 64GB laptop can be a lot more expensive compared to 500GB laptop. The storage capacity is clearly limited and can be a lot more expensive.
Before considering SSDs for office and small businesses, always consider the price of the technology. There are situations wherein an expensive upgrade is a must but a business can also wait until SSDs become more affordable.
