Should I buy a Samsung 980 PRO SSD without DRAM?

Samsung Electronics deserves a throne in the high-tech memory industry, as they not only update future standards to SSDs, but they also boldly cut other hard drive components but still ensures impressive performance.

And the NVMe SSD 980 Pro line is the company’s first DRAM-free SSD, whose biggest purpose is to minimize production costs, from which general users will have the opportunity to access hard drives. NVMe SSD just got easier.

NOTE: In this article I refer to the hard drive SSD Samsung 980 PRO NVMe standard, supports PCIe 4.0, not normal / no-mark-Pro with older PCIe 3.0.)

#first. The genius of Samsung

The DRAM-cut idea has been around for a long time, but in the past, this design has a fatal weakness: data retrieval speeds are greatly reduced when there is a lack of DRAM cache.

That is no different than making NVMe reverse evolution, when hard drive technology standards (SATA, M.2) in particular came out with the ultimate goal of enhancing data processing performance.

Fortunately, the NVMe standard supports Host Memory Buffer (HMB), so Samsung can take advantage of the CPU’s 64MB of DRAM via a PCIe connection to do the work of the caching.

Samsung is confident that its non-DRAM SSD is still at least six times faster than a traditional SATA SSD.

It sounds simple, but behind it are vast improvements in technology, as well as its proprietary architecture.

With 6th generation V-NAND architecture, Elpis SSD Controller and Intelligent TurboWrite 2.0 help increase Allocated Buffer Region leveling capacity up to ~ 120GB (for this 980 Pro series).

It is obviously much higher than the 42GB of the predecessor 970 Evo (technically this performance puts 3-bit Multi-Layer Cell / MLC on par with even the latest Single-Layer Cell / SLC architecture. ).

#2. Samsung 980 PRO SSD specifications and price

The interesting thing about Samgsung’s NVMe SSDs is that the larger the capacity, the higher the overall performance, due to the more channels of NAND available.

According to information that Samsung announced, with the mainboard supporting PCIe 4.0, the NVMe SSD 980 Pro delivers sequential read and write speeds (Sequential Read-Write) 7,000MB / s and 5,000MB / s, respectively, 2 times faster. compared with PCIe 3.0 SSD, 13 times more than traditional SATA SSD.

Yes, a very impressive number is not it 🙂

In TheVerge’s test with Samsung SSD 980 Pro plugged into the M2 slot of the PCIe 3.0 port on the motherboard (note that this NVMe hard drive is compatible with the M.2 slot, supports the latest PCIe 4.0 Interface standard). :

The maximum sequential read and write speeds are 3,500 MB / s and 3,450 MB / s respectively for the 1TB version ($ 229).

For the lower capacity, the read speed will remain the same, but the write speed will gradually decrease as follows: 3,400 MB / s for the 500GB ($ 149) and 2,700 MB / s for the 250GB ($ 89).

Other specifications:

  • Random Read / Write Speed ​​(QD32) is: 500K IOPS / 480K IOPS
  • Supported data encryption standards: AES 256-bit Full Disk Encryption, TCG / Opal V2.0, Encrypted Drive (IEEE1667)
  • Total Bytes Written: 600TBW for the 1TB version, 300TBW for the 500GB version, and 150TBW for the 250GB version.

It can be said happily that, although the NVMe SSD 980 Pro is “disabled” in DRAM, it still beat the “healthy” seniors 970 Evo: The maximum sequential write speed of the 970 Evo series is 3,500 MB / s and 2,700 MB. / s (you should remember that the maximum of 980 Pro on PCIe 4.0 is 7,000 MB / s and 5,000 MB / s, the difference is quite large).

# 3. Where to buy Samsung 980 PRO SSD hard drive?

You can order this SSD hard drive on e-commerce floors in Vietnam, there are also many places to sell, so shopping is not difficult at all.

Also, you can visit the link below (there will be more options for you).

# 4. summary

If you are a general user, you should understand that the simple purpose of this article is to help you have a more affordable choice between the budget and the performance of the SSD in the context of today’s besieged technology standards.

You should invest in a non-DRAM NVMe SSD instead of traditional SATA SSDs, because the hard drive’s access performance, durability and power savings (the slowest PC component) are well worth the investment. .

And at this point, you probably have already answered the question yourself: should you buy a Samsung 980 PRO SSD without Samsung DRAM or not!

Personally, I recommend: It is best to always use 2 hard drives for a computer, an expensive one using NVMe standard running OS + fast data storage, and a cheaper SATA standard to store data. Large capacity and backup data backup.

Or to save costs, you can also use a combination of an SSD hard drive as the operating system, and an HDD to store data. This depends on your circumstances.

See you in my next articles, in the following article I will talk more about SSDs technology standards in terms of size, technology, price and performance. Please keep an eye out 🙂
