When I have a question about SSD retail pricing I know exactly who to consult. Andy Higgenbotham (pictured here) and his Price G2 service track HDD and SSD retail pricing and publish data to a very high degree of resolution.
Price G2 data has been used in another post in the blog: When Will SSD Prices Drop Below HDD Prices?
This company publishes weekly reports of pricing from all major HDD and SSD manufacturers (Seagate, Western Digital, Toshiba, Samsung, Intel, Micron, and the like) with information on market trends like this for the week of April 23:
Flat to increasing pricing continues throughout 2012. Only on the 512GB have we seen sustained price drops from Q1 and through Q2. The 512GB capacity currently sells for $1.05/GB in week 17.
Amid recent rumors of steep SSD price declines this service has served to disprove any notion that the SSD market is undergoing fundamental change. The SSD Guy highly recommends Price G2 for anyone whose business relies on timely and thorough HDD and SSD price tracking.
