Samsung 860 QVO vs 860 EVO vs 860 PRO: 1TB SSD Comparison – Which One Should You Buy?

Advertisements

Today we are going to check out, review and compare Samsung’s current SATA SSD lineup. Samsung released the 860 PRO and 860 EVO SSD Series early last year. Both SSD lineup are very solid and the 860 EVO became one of the most, if not the most, popular SATA SSD that the market has to offer. Late last year, Samsung released a more “budget friendly” SATA SSD – the 860 QVO SSD series; featuring the company’s high-density 4-bit multi-level cell (MLC) NAND flash architecture. Now, we basically have three 860 SSD series to choose from. I usually get questions like; “which of the Samsung 860 SSD is the best / fastest?“, “which one is has the best value for money?“, or “which Samsung 860 SSD is the best for an OS drive or gaming driver?“. In this review, we are going to compare the Samsung 860 QVO vs 860 EVO vs 860 PRO SSDs. We’ll be comparing their respective 1TB SSD capacity since it’s the more popular or commonly used capacity nowadays. Each of us has different needs and different budget. So go ahead and check out the review below and find out which of the Samsung 860 SSD series is the best one for you.

Samsung 860 QVO vs 860 EVO vs 860 PRO 1TB SSD Review

Samsung 860 QVO vs 860 EVO vs 860 PRO SSD Review – Features

Let’s discuss the Samsung 860 PRO SSD series first. The 860 PRO is currently the company’s flagship SATA SSD. It features Samsung MJX controller paired with Samsung’s 64-layer 3D 2bit MLC V-NAND flash memory. It’s available from 256GB and up to 4TB capacity. The speed is similar across the capacity; with a sequential read speed of 560MB/s and a sequential write speed of 530MB/s. Speed and the endurance rating or Total Bytes Written (TBW) is what separates the PRO series from the EVO and QVO. But it’s also the most expensive one as well. Although its warranty period is similar with the 860 EVO series, its TBW is doubled. You can check it from the tables below.

Up next is the Samsung 860 EVO SSD series; it’s undeniable the most popular SSD series in the market. It offers similar or near the performance of the 860 PRO SSD series, but at a more affordable price. The Samsung 860 EVO also features the MJX controller, but it is paired with a 3bit MLC (a.k.a TLC) 64-layer 3D V-NAND flash memory from Samsung. It has the same DRAM cache memory configuration per capacity with the 860 PRO series, but it has a slightly slower speed. The 860 EVO SSD series features a sequential read speed of 550MB/s and a sequential write speed of 520MB/s. The endurance rating or Total Bytes Written is also halved. The 860 EVO 250GB capacity has a TBW of 150TB only and the 860 EVO 4TB has a 2,400TB of TBW only. Though, it has the same 5 year limited warranty period with the 860 PRO. This means, that the 860 PRO could handle double the amount of data written compared to the 860 EVO series; making the 860 PRO a more suitable storage solution for write-intensive applications or setup.

Finally, the newest member of the 860 series is the Samsung 860 QVO SSD series. It features the same MJX controller paired with Samsung’s 4bit MLC (a.k.a QLC) 64-layer 3D V-NAND flash memory. It’s only available in three capacities: 1TB, 2TB and 4TB; with a DRAM cache of 1GB, 2GB and 4GB LPDDR4 respectively. It has the same sequential read and write speed with the 860 EVO, but 4KB random read and write speeds are quite slower compared to the 860 EVO’s 4KB random read/write speeds. On top of that, the Samsung 860 QVO’s endurance rating or TBW is almost half (60% to be exact) from the TBW offered in the 860 EVO with the same capacity. See specifications below. Aside from the endurance rating being lower, the warranty period is down to 3 year limited as well. The only good thing that went down with the 860 QVO is the price. The 860 QVO is cheaper compared to the 860 EVO, at the expense of speed, endurance/reliability and warranty.

All the Samsung 860 SSD series features AES 256-bit Full Disk Encryption, TCG/Opal V2.0, and Encrypted Drive (IEEE1667); and supports TRIM, Garbage Collection and S.M.A.R.T as well.

Another thing worth mentioning is that both the Samsung 860 EVO and 860 QVO features Intelligent TurboWrite technology. This significantly accelerates the write speed of the drive during data transfer. However, after the buffer has been maximized, the TurboWrite will exit resulting to a significant drop in write speed.


The 860 QVO has the same TurboWrite capacity for the 1TB and 4TB with the 860 EVO, but has a larger TurboWrite capacity for the 2TB capacity. Unfortunately, once the TurboWrite Size has been maximized, the write speed can go as slow as 80MB/s for the 860 QVO.

    Good review, I found it really helpful as I am trying to upgrade my current 256GB SSd from my laptop. This definitely helped so thank you a lot and keep up the good work.

    1. The PC Enthusiast says

      I’m glad it helped you!

    I replaced my 1TB HHD with an 860 QVO 1TB. The time the laptop took to initialize and open all my app in the task bar was phenomenal. However, after the third or fourth time turning on my Dell laptop, I began noticing the laptop was not booting when turned on. The only way I could get the 860 QVO to communicate with the main board was to remove all power supply, open the cover to the SSD drive, pull 15/7 pin from the SSD and reattach it; then then power up the laptop. Usually the Dell laptop booted upon turning on the power. Unfortunately I need to do this procedure almost every second time. I ended up replacing the SSD with the old and much slower HHD.

    Thanks for taking the time and effort to produce this review, it helped me to decide to go with an EVO 1 TB.

    1. The PC Enthusiast says

      Great! 🙂 EVO all the way!

  4. Janwo says

    Well, the QVO is perfect for data storage, but for every other purpose the EVO is much better!

  5. Eugene says

    Right now I’m running a 1TB Samsung EVO SSD and 2 other Samsung 500 GB’s which are a few years older and running my OS on a 970 EVO Plus 500GB.. I also have an old 1TB Hitachi HDD that I use for cold storage. I see that the QVO 1TB is on sale and I’m thinking it would be the natural fit to retire my last HDD.

    1. The PC Enthusiast says

      Just remember that it may take a while for you to transfer all your files from the HDD to QVO, since QVO has lower sustained right speed. Once it max out its cache, write speed drastically drops.
      I don’t use SSD for cold / long storage, specially if the files are considered (very) important. I would get something like a WD Red (Pro) for that. Problem with SSD, is that when they fail, they just fail and all files are lost.
