Pros
- There was no time to write a review, finally decided. The SSD was purchased in 2022. Manufacturing process: 128-layer 256Gb TLC 3D V-NAND (3-bit MLC), 8nm Elpis controller, Memory type - LPDDR4. Elpis is designed specifically to work with 6th generation memory and PCI-E 4.0. SLC caching is performed using Intellegent TurboWrite 2.0 technology - more advanced than in the 970 EVO Plus, there was Intellegent TurboWrite 1.0. The larger the storage capacity, the larger its capacity can be used by the dynamic cache during SLC caching. Therefore, the 2 TB option, when using the cache, gives higher linear read and write data, as well as more IOPS. Sequential read speed - 7000 MB / s, sequential write speed - 5000 MB / s (but this is only for motherboards with PCI Express 4.0). The proprietary Samsung Magician utility, there are no complaints about it, you can analyze the real read and write speeds, temperature and the filled volume of the SSD.
Cons
- 1. It is a pity that there is no volume of 4 TB, unlike competitors, I wanted just such an SSD. Samsung has a 3.84 Tb SSD, but these are different drives. Here you have to sacrifice volume for the sake of performance. 2. Declared read and write speeds only for motherboards with PCI Express 4.0 slots, in fact, on PCI Express 3.0, approximately at the level of 970 EVO Plus, 2 times less, here the sequential read speed is 3500 MB / s, and the sequential write speed is 2600 MB/s Therefore, you need a motherboard with support for PCI Express 4.0. 3. Before buying a second m.2 SSD, you need to consider the number of processor lines (relevant for Intel). If you have a 28 lane gem and have 1 SSD, it will take X4 lanes and you are left with X16 for the graphics card and X8 for the other Pci-Express slots. You need a 44 or 48 lane CPU, then you can even plug in 4 m.2 SSDs in X4 mode. I had to replace my i7 -7820x with an i9-10980XE first. In the future, I plan to completely change the entire configuration in order to feel the declared read and write speeds.
