The 870 EVO family is designed to inherit the famous 860 EVO models after more than three years of hiatus, thanks to the new generation TLC chips
NVMe and QLC technologies have become the leading forces in the non-volatile storage market over the past two years - but it is Samsung that is deciding to bring back trends from the past back to the center of the stage now, with a series of drives SSD In an old SATA III interface based on chips NAND In TLC configuration.
The new 870 EVO models are designed to land On the market a little over half a year after the launch of the 870 QVO models Which included chips NAND In a more compressed QLC configuration that is considered less quality and reliable than TLC (with support for four different voltage levels in each compartment for storing three bits of size, compared to eight voltage levels in each storage compartment for four bits of information) - and the products show considerable similarity due to using the same controller Storage and in the same volumes of Memories Dynamic.
The 870 EVO drives can be found in stores in volumes ranging from 250 GB to 4 terabytes at the top end, including 512 MB to 4 GB of LPDDR4 memory and self-developed MKX controller of סמסונג Works in all and promises to deliver continuous transfer speeds of up to 560MB / s in read and up to 530MB / s in writing, along with random performance of up to 98,000IOPS in read and up to 88,000IOPS in write that exploits the potential of the SATA III / AHCI interface The versions.
On paper, these figures are very similar to those of the mega-popular 860 EVO models that were introduced somewhere in 2017 - but we already know that in the storage market many of the differences are reflected in practical uses that are not adequately addressed in the public technical data, and here Samsung assures us that the new generation is capable of providing up to 38 percent improvement in random performance in an aggravated QD1 configuration (with no parallel operations), which is much more common among average home users compared to the QD32 configuration whose flattering random data is published in most cases. In other words, Samsung is convinced that the new model will be able to provide a significant improvement for a large part of the users compared to the model that is already in a high position in the performance tables of this old interface - thanks to the combination of modern storage controller and new generation TLC chips in 128 layers with 512 g storage capacity 'Gigabit for all chip, Compared to an internal structure of 64 layers in the TLC chips in the corresponding models from the past.
All 870 EVO drives will be offered with a five-year warranty, at a writing rate of 30 percent of the full daily drive volume which is an improvement over the warranty of the 870 QVO models. The official recommended prices were updated near the launch date, and now stand at $ 40 and $ 70 for basic 250GB and 500GB volumes for starters, through $ 130 and $ 250 for storage Of one terabyte and 2 terabytes respectively and up to $ 480 for 4 terabytes making the most generous volume the one with the most enticing relative cost.
Buy as soon as there is an opportunity, or maybe wait for the 870 Pro models that are also in the preparation stages according to some reports? Feel free to share your personal perspective in the comments right now.
