Generally when I talk to people about SSDs and how great they are, two concerns almost always pop up. The first concern of course is cost. While cost has been getting more and more competitive in the past few years, SSDs are still relatively expensive compared to HDDs. The second concern is capacity. Whereas HDD capacities practically start at 500GB to 1TB, SSDs generally cap out at 512GB or 1TB. That said, whereas it was almost impossible to find SSDs under the~$0.50/GB pricepoint just two years ago, it’s relatively easy to find drives down in the~$0.30/GB pricepoint today. In the next few years, prices are expected to continue to drop as NAND density increases which should not only lead to higher capacity SSDs, but also lead to price parity with HDDs sometime in the future.
Since cost and capacity have always been some of the biggest concerns, we always raise these concerns with the SSD vendors whenever we get a chance. As such, we learned back at CES that Samsung had the capability of producing 2TB SSDs, but at the time the cost would be prohibitively expensive to sell to the mass market. With Samsung’s 3D V-NAND process now mature, stable, and cost effective enough for mass market production, Samsung is releasing both their 850 EVO and 850 PRO SSDs at the 2TB capacity.
