Hi Jim, yes, UK pounds and for sure that 2TB SSD is aimed at the enterprise market, and i doubt many home users would be prepared to spend that much on an SSD.
SSDs however make a very noticeable improvement to performance if you use a small one for your OS and applications. Most modern SSDs can access data 100 times faster than even the fastest traditional HDD.
The solution i use, and many others is to have an SSD for OS and applications of about 60GB - 120GB, and use traditional large capacity HDDs to store data, such as video, audio and pictures. This hybrid system works extremely well.
