samsung 850 evo 500 gb internal ssd for mac

Even the latest 2TB capacity has the suggested price of just $800 (or 36 cents per gigabyte) and its street price will likely be lower. The 850 Evo is the cheapest Samsung SSD at launch with most capacities currently costing just slightly more than 30 cents per gigabyte. For example, you can use the software to enable or disable over-provisioning (a feature that uses part of an SSD's storage space to enhance the drive's performance) and encryption, as well as apply different settings that are optimized for the drive's performance, endurance or reliability. Other than that, you can use the Samsung Magician software to manage other features and settings of the drive. Generally, RAPID mode uses up to 4GB of RAM or 25 percent of the host computer's total system memory, whichever is less. Once enabled, RAPID mode works by itself and automatically adjusts the amount of RAM it uses based on availability. The software supports the new RAPID version v.2.1 that now, according to Samsung, enhances error handling and fixes some compatibility issues.

To use RAPID on the 850 Evo, you'll need to install Magician 4.5 (included on a CD, though you can also download it). Since most new computers come with a large quantity of RAM, RAPID is really a welcome feature. RAPID stands for Real-time Accelerated Processing of I/O Data and it uses the available system memory (RAM) on the host computer as an input/output cache to boost the computer's performance. The drive supports SATA 3 (6Gbps) but will also work with SATA 2 and the original SATA. It's a standard 2.5-inch internal drive that's 7mm thick. Otherwise, the 850 Evo looks just like a 850 Pro or the 840 Evo. The 500GB, 1TB and 2TB capacities' endurance is doubled (150TB) and will take even longer to run out. This means you can write 40GB per day to the drive every day, and it will last for at least 5 years.

Specifically, the 850 Evo's 120GB and 250GB capacities have an endurance rating of 75TB. Similar to the 850 Pro, Samsung also claims that the 3D NAND delivers very high endurance, which is the rating that quantifies the total amount of data that can be written to an SSD before the drive becomes unreliable. This greatly increases the density and means, among other things, more storage space for less cost. With the 850 Evo, the drive's flash memory cells are stacked in up to 32 layers, which allows for significantly more cells in the same number of wafer bits. That's common for most SSDs on the market. Traditionally, 2D planar type NAND flash memory cells - the storage units on an SSD - lay flat on the surface of the silicon wafer. Following the 850 Pro, the 850 Evo is the second SSD from Samsung that uses a 3D vertical flash memory cell.
