SSD’s increase performance, by accessing data much quicker, and lower power consumption – with no mechanical parts moving around they’re quicker and draw less power. The main issue for the adoption of SSD’s today is their high prices – only 32 GB SSD’s are really priced in the consumer field.
However, according to an article published today on Tom’s Hardware that compared several flash drives, SSD’s with capacities of 100+ GB will soon reach the $500 mark, and prices will only fall further from there. The costs of SSD drives are coming down as the price of flash memory does as well. Today’s prices will be halved, at least, by the end of the year making solid state drives a much more attractive buy.
