Samsung announced that they would be releasing 2TB versions of their popular 850 Evo and 850 Pro families a couple of months ago, but thus far no one has spotted the drives out in the wild. That is up until now, they have been spotted in shops, are available through Samsung directly, and can be ordered from multiple online shops with others taking pre-orders until stock arrives.
While 2TB SSDs aren’t anything new in themselves, this is the firs time that we get this capacity on the consumer level and at a more reasonable price. Both drives are built with 40nm V-NAND, but not the same type. The Evo drive is built with TLC Toggle while the Pro is built with MLC Toggle NAND. The new Samsung 2TB drives are using 2GB LPDDR3 Cache to help with the performance and utilize the Samsung MHX controller.
The two series aren’t far from each other when it comes to performance. The Pro can read with 550MB/s where the Evo only does 540MB/s in sequential operations and the random performance of the Pro is 2K higher and comes in at 100K IOPS. The write performance is identical on both series with 520MB/s sequential and 90K IOPS random 4K.
I mentioned earlier that these drives come at a reasonable price, whether that is true or not probably depends on your absolute needs. The Samsung 850 Pro can be had for around 900 Euro while the Samsung 850 Evo is a little cheaper and can be had for around 720 Euro. Those prices are actual list prices and might variate depending on the retailer. The MSRP for the drives has been set to $1000 and $800 respectively.
