Samsung's New 860 Pro SSD Maxes Out at 4TB for $1,900

Samsung on Tuesday unveiled its new 860 Evo and 860 Pro SSDs, the Korean tech giant's latest efforts to quench the thirst of PC builders for always-college data throughput speeds.

Scheduled to be available for purchase by the stop of the calendar month, the 860 Evo offers a maximum sequential read speed of 550 MBps, a slight bump over the 850 Evo'due south 540MB/southward read speed, thanks to in part an improved controller that handles communication with the host organisation.

The slight speedup is also thanks to the latest V-NAND technology, which rearranges the wink memory cells in vertical stacks instead of horizontal ones to boost their speed and longevity and reduce their power consumption. Samsung'due south 850 Evo was the first drive to feature this new cell arrangement when it debuted in 2022.

The latest revision of Five-NAND architecture used in the 860 Evo enables the drive to transfer information at speeds that approach the 600MBps limit of the SATA interface. In addition to the 2.5-inch SATA course factor, the 860 Evo is also bachelor in mSATA and 1000.2 varieties. The 860 Pro, meanwhile, is bachelor but in a ii.5-inch course cistron and offers a slightly higher maximum read speed of 560 MBps.

Random read and write operation, which impacts things like operating organisation boot times, has besides increased slightly from the 850 series, especially at lower queue depths, co-ordinate to Samsung's internal testing.

The 860 Evo comes in 250GB, 500GB, 1TB, 2TB, and 4TB capacities, starting at $94.99, while the 860 Pro has 256GB, 512GB, 1TB, 2TB, and 4TB versions starting at $139.99 and topping out at $1,899. Check the pricing nautical chart below for more than details.

Other than slightly faster information throughput capabilities, perhaps the most unique role of the 860 Pro is its warranty. It's rare to meet a difficult drive with a warranty that's greater than three years, only Samsung says it's confident plenty to guarantee the 860 Pro will work for five years or upwards to iv,800TB of information written for the 4TB version.

Organisation builders have been eagerly anticipating the rumored successor to the 850 Evo, and their anticipation reached a fever pitch last week when a listing for the 860 Evo was mistakenly added to Samsung's website. It was pulled a few hours later on.
