Samsung's line of solid-state drives are among the fastest SSDs on the market. The 850 Pro series improves upon the well respected 840 Pro with higher speeds and a doubled warranty length of 10 years (or 150TB of writes). It uses the industry standard SATA 6Gbps interface and supports 256-bit AES drive-level encryption. This specific 256GB capacity model reaches up to 550MB per second for reads and 520MB per second for writes, and in excess of 90k IOPS.

Perfect for notebooks, SSDs are ideal for energy-efficient mobile computing to extend battery life, increase access time, and provide a durable alternative to conventional hard disc drives with superior shock resistance. High capacities and low power consuming NAND flash technology provide the necessary performance and battery life boosts generated by the proliferation of mobile gaming and new ultra-thin laptops. With fast access and seek times combined with excellent reliability, SSDs are the answer for consumers demanding this latest storage technology.

The performance on this drive is great, and 10 year warranty is downright amazing. We have a long history with Samsung SSD, and they are the most reliable and consistently best performing drives we've ever worked with.

Jeff Stubbers (Tier 3 Consulting Lead) Says:
This is a very fast drive, has a lower failure rate than mechanical drives, and comes with a 10-year parts warranty from Samsung. I tend to recommend a 500GB or larger SSD for Windows OS though, and these smaller drives for either scratch drive or Secondary drive.
