Samsung SSD 870 QVO, maximum capacity and SATA performance

Samsung SSD 870 QVO is the latest internal storage solution for the South Korean manufacturer’s customer segment. The goal of this series of solid state drives is clear: to extract the maximum performance from the SATA interface and offer the highest storage capacity in the industry for a consumer SSD: 8 Tbytes.

Samsung disputes with Intel the first world position in income by semiconductors, but in the market of solid state drives “there is no one to cough up.” Leading the flash memory segment since 2003 and leading the sales of some SSDs that today they completely monopolize the consumer storage market and they are entering the business market with force.

We have already told you ad nauseam about the advantages of SSD over hard drives in terms of performance, consumption, noise or heat emission. The Samsung SSD 870 QVO offer them, but also, they come close in another aspect where the HDDs were until recently unattainable with this new 8 Tbyte version. Taking advantage of the launch, Samsung has given us a unit (2 TB) that, although it does not reach that impressive capacity, allows us to get closer to what this series offers.

Samsung SSD 870 QVO

Special mention for the QLC memories used by these Samsung SSD 870 QVO, the second generation of the company after its premiere in the 860 series. The storage of four bits per cell is a great density increase compared to the TLC (triple level per cell) that dominate the current market and previous technologies such as MLC and SLC (only one level per cell) that we are not seeing in the consumer market.

Samsung combines this technology with its 4-bit V-NAND chips to achieve capabilities that until recently were unknown in solid state drives. At the same time, lower production costs to offer the same capacity must result in a cheapest price per GB for the end customer.

On paper, not all are advantages. Increasing bits per cell tends to slow performance especially for writes. Samsung has solved it with its own technology called TurboWrite and the truth is that as you will see in the tests, the results are at the maximum of what the SATA interface allows.

The resistance of the units also suffers. Always on paper because not enough years have passed to prove it. Although other large flash storage manufacturers such as Toshiba promised to match QLC’s endurance to that offered by TLC memories (1,000 program / erase cycles), the new Samsung SSD 870 QVO only have a three-year warranty when the 5 years established in such a way generated for the business market are already the norm in the consumer market.

In any case, SSDs have free cells to occupy when others fail and the guarantee of written bytes is very high. Surely a typical user will never reach it and the unit lasts much longer than the three warranty it officially offers.

Use and installation cases

If NVMe SSDs stand out for their higher performance, minimum footprint and better energy efficiency, drives that connect to the SATA interface like this Samsung SSD 870 QVO offer the advantage of compatibility, since you can use it on a huge number of new or old computers.

You can install it in the same way on laptops or desktop PCs and for various use cases. As a single unit replacing hard drives; along with several SATA drives and also as a secondary drive in computers that have NVMe for boot taking advantage of its large capacity and better price than these.

This time, we have installed this Samsung unit in an MSI Leopard laptop that we use for testing. We leave you its main characteristics, although we have already said that its benefits (compared to a hard drive) are enormous regardless of the use case and equipment.

  • 15.6 inch FHD screen
  • Intel Core i7-7700HQ Processor
  • NVIDIA GTX 1050 Dedicated Graphics
  • 16 GB of DDR4-2133 MHz RAM

For the review, we have retired the storage units that we had installed using only the Samsung unit to obtain the highest fidelity of the results, with installations from scratch and tests on Windows and Linux.

In a real use case, we recommend you make a file backup prior to safeguard the files and personal data that you want to reserve or perform a complete clone of the drive to restore it later on the new SSD. In this regard, comment that Samsung offers the application on its support page Data Migration Software that makes the task easier.

Installation is as simple as we have seen in previous reviews or in this practical article “How to replace a hard drive with an SSD in a laptop”. To do this, we remove any type of connected peripheral, the power cable and the battery if it is removable. We check the rear and remove the hardware to access its interior.

Although it will vary by laptop model, you won’t have too much trouble locating the SATA storage drive situation. (If you use a desktop it will be even easier. You remove the top of your tower, find a free 2.5-inch bay or 3.5-inch adapter and connect the power and data cables).

Samsung SSD 870 QVO

In the laptop, we locate the bay available for SATA, remove other drives present, install the drive, secure it with its screws and remount the laptop lid. We connect the battery in its case, power cable and peripherals and we must have it ready to work.

In the first boot of the laptop, we enter the BIOS / UEFI with the corresponding key to make sure that the unit is correctly installed and the computer recognizes it.

From there and depending on the type of backup we had made, we would use the cloned copy to activate it on the new drive or we would install the operating system and then copy the saved data.

Performance on Windows and Linux

To ensure the reliability of the performance tests, we conducted a installation from scratch with the latest stable versions of Windows 10 and Ubuntu. The installation of systems in solid storage units is a luxury compared to hard drives and in both cases, from a USB 3.0 connected USB stick, the process takes no more than seven minutes.

We split the available space on this drive between Windows 10 and Ubuntu 20 to check both in a dual install. If you are interested you can review our latest guide to install Windows and Linux on the same computer.

Windows testing

After installing the latest stable version of Windows 10 2004, we update the system with the latest available patches, as well as all the computer drivers. The next thing is to install the Samsung Magician, the manufacturer’s official application to manage storage units.

With an attractive interface, the software offers information about the unit, its current status and the firmware update. It also includes SMART diagnostic tests; over-provisioning capacity; TRIM status; secure erasure of all data on the drive; possibility of implementing disk encryption and a RAPID mode to accelerate the overall performance of the system that we discarded in the analysis because the results obtained are too high for a SATA drive. Complete, attractive and easy to use software.

The first test we run is the popular CrystalDiskMark. The performance offered in sequential reads and writes is fantastic, matches that established by the manufacturer and is practically at the limit of what the SATA-III interface can offer.

Finally, we have run the global PC Mark 10 test. Futuremark’s benchmark is one of the most comprehensive in the industry and runs several performance tests for personal computers, evaluating daily tasks such as browsing websites, video chat, writing and spreadsheets, editing photos and videos or games. The intention is to check if the results vary compared to other storage units, but no, in these high-end SATA the score is practically identical to that achieved by this same team with other units.

Linux testing

As we do in the analysis of solid state drives, we also installed the latest stable version of Ubuntu 20.04, in order to evaluate the behavior of the drive with other operating systems. Installation is just as fast and the Canonical system recognizes the drive without any problem and offers the same benefits as Windows versus a hard drive in terms of system and application startup, file movement, or recovery from modes. suspension.

For what interests us. Be it Windows or Linux, the systems recognize the drive without problems and in both it offers great results.

Samsung SSD 870 QVO, versions and price

Another standout series (and we’ve seen a few top-tier SSDs already), at the maximum performance of what the SATA interface can offer and with the possibility of opting for the largest storage capacity currently offered by the industry for an SSD of consumption: 8 Tbytes. A guarantee from the leader in solid state drive sales that receives the award for recommended product.

Samsung SSD 870 QVO is available in the Spanish retail channel in four versions according to capacity, 1, 2, 4 and 8 TB, and with prices starting from 132 euros. The tested 2 Tbyte drive is priced at 232 euros (0.11 euros per GB) and on it we make the assessment.

Final assessment


Samsung SSD 870 QVO is the latest internal storage series for the South Korean manufacturer’s customer segment. At the maximum performance of the SATA interface, it raises the storage capacity to 8 Tbytes, the maximum of SSD in consumption. With a very economical price per GB, it allows installations on any computer, desktop or laptop. It has a 3-year warranty, while other manufacturers offer five years.
