High-performance 500 GB consumer SSD from the popular EVO line, which combines high-performance and reliable drives from the Korean giant Samsung. It is positioned as a product of the upper part of the middle price category. Made in a compact form factor M.2 2280, designed for installation in gaming computers and consoles, laptops, ultrabooks and desktop workstations. The hardware basis of this model is a high-performance multi-channel Samsung Phoenix controller with a 1024 MB DRAM buffer based on LPDDR4 memory.
64-layer proprietary 3D TLC V-NAND flash memory features enhanced reliability and decent I/O performance. Together with the PCI-E 3.0 bus and support for the NVMe protocol, the drive provides sequential read and write speeds up to 3400 MB/s. In fact, this is the ceiling of this bus, only drives with a PCI-E 4.0 interface can work faster. In addition to high linear speeds, high efficiency should be noted: the IOPS of this model is close to 0.5 million operations per second, which significantly affects the performance of the drive under simultaneous high loads, for example, copying a huge number of small files at a time.
In addition, the drive supports high-speed SLC caching technology, which provides excellent performance of the drive as a system drive. All these factors make the Samsung 970 EVO an interesting option for a fast system storage, fast archive or game library. A high level of reliability is confirmed by a 5-year official warranty and a decent guaranteed write resource (TBW) of 300 TB.

It was good for its time in 2021. I recommend taking something else, like a Kingston, or Krushal on Gen4. At least 500 GB. Durability. It works for a long time, maybe it will survive another 5 years.
Speed. With hdd sata there was a noticeable difference Nope.  Влад: use Samsung MZ-V7E500BW more than year |
Year model. The tenth Windows is loaded in 6 seconds (not counting the loading of the "bios" and post-screen). Speed
Design (looks good on the board) Not yet use Samsung MZ-V7E500BW few months |
I took this drive for a Mi Laptop Pro laptop, there is an extra. slot M2, because there is not much of its memory there and another drive was needed for the so-called D drive. SSD was taken many years ahead, so it was chosen carefully, maximum speed and quality. Installed in a laptop without problems, everything flies as expected, the speed is impressive. For example, installing a 30 GB game, unpacking took about 1 - 1.5 minutes, the copy speed within the drive was around 1200 MB / s. Of course, it should be noted that the form factor is very convenient, I didn’t use it before, but here there are no plumes, no power, I just inserted it into the plug and flew. The maximum that I saw is heated up to 40 degrees under load. Speed and more speed Nothing of course Віктор С.: use Samsung MZ-V7E500BW few months |
Reference SSD upgrade
Thanks to the full closed cycle, Samsung has been able to release reference SSDs time after time, which set new performance records and fully justify the Evo name. By switching to a more powerful Phoenix controller and a new 64-layer 3-bit memory, it improved its predecessor's speed characteristics, received a more generous write resource and fell slightly in price.
Movement at supersonic speed
Linear read and write speeds within a 10-gigabyte SLC array are 3400 and 2300 MB / s, which is 5-6 times faster than top-end SATA SSDs. When the array overflows, the read speed does not change, and the write speed drops by a factor of three. A common story for MLC memory, however, it is not so common to operate files of 10-20 GB in normal life, so it's okay. Even more impressive is the processing speed of the smallest 4K blocks: 450K and 370K IOPS for reading and writing, respectively. The credit for this is not only the fast Samsung memory and the Phoenix controller, but also the DDR4 cache RAM instead of the low-frequency DDR3.
Not a revolution, but an evolution
If we average linear and random read/write performance, then the latest Evo model will be many times faster than its predecessor in the face of Evo 860. However such a revolution as last time did not happen, and the new Evo does not leave competitors far behind, as before. But the price is better this time. If you are planning to assemble the fastest gaming computer in the world and these figures are not enough, then look towards the older model 970 PRO — it is more expensive, but in terms of performance it turns out to be almost 25% more powerful.
