If solid state drives (SSDs) are to ultimately replace standard hard disk drives (HDDs) as the default storage option, they're going to have to do it the old fashioned way - by offering a better, or at least comparable, bang for buck.
Because Windows 7 offers better support for SSDs than either Vista or XP, it was thought that Microsoft's upcoming OS might help bolster SSD sales and push the flash-based storage medium further into the mainstream. But this isn't likely to happen, say notebook vendors, who point out that the price gap between SSDs and HDDs is still too large.
SSDs currently check in at about $4-5 per GB, whereas HDDs cost less than $0.50 per GB, and that includes some higher end models. And despite rapid advancements in SSDs, it might be another three years before HDDs are finally dethroned.
