Solid state drives have come a long way since its early days and it looks increasingly likely that they're going to see strong adoption in notebook PCs and elsewhere in the relatively near future. One disadvantage over mechanical disks, however, is that they are significantly more expensive and most users are of course reluctant to give up cheap cost-per-gigabyte storage. But this won't remain for long, according to Samsung
The company reasons that while each technological leap in increasing the storage capacity of traditional HDDs does not add significantly to the total price of the drive, the opposite has been true with solid state drives, where each gigabyte of storage scales almost linearly as more chips are added to the drive. However, as flash memory prices drop and densities and capacities increase, Samsung predicts we'll see price parity between the two technologies within “the next few years.”
That is not exactly a hard prediction to make but it is still important coming from the world’s largest flash memory maker. Though the company did not offer a more specific time frame for this to happen, it did claim the sweet spot for SSDs in terms of pricing per gigabyte will go up from 128GB to 256GB this year.
