Samsung SSD 850 Pro 128 GB Review Benchmark values and test results

Benchmark values and test results …

Let us continue with the benchmark results. SATA3 drives are tested with an ASRock 890GX Extreme3 motherboard and test results of mSATA and M.2 modules are performed using an ASRock Z97 Extreme6 motherboard. At present, Microsoft Windows 7 Ultimate Edition is used as the operating system.

The SSD drive speed was examined and compared with the following benchmark software:

AS SSD benchmark results

The AS SSD benchmark values offers a very good reference point of the maximal possible reading and writing performance, the speed with smaller files and the respective access time. The Samsung 128 GB SSD achieved an relatively good sequential read and write speed in AHCI mode.

Although you should operate the SSD in AHCI mode, we have spared no effort to run all benchmarks additionally in IDE mode. The total score in the IDE mode (indicated by ‘pciide’ below firmware EXM02B6Q) reached good 409 points. However, the result is in AHCI mode with 910 points however two times higher.

Here is a screenshot of AS SSD benchmark values (SATA3 IDE):

In AHCI mode also another result beneath the better read performance is much higher than in IDE mode and that is the important value “4K-64Thrd”. 4K means that small 4K blocks are read and/or written and with the 4K 64Thrd this is distributed on 64 Threads at the same time. Thus the benchmark program simulate for example a typical program start.

Because the weighting of this value in the AS SSD benchmark tool is very high, the total score in AHCI mode is more than twice as high with 910 points.

The usable capacity of the Samsung 850 Pro is 119.24 GB. With the Samsung tool you can also customize the Over Provisioning area and therefore determine how high you would adjust the SSD durability vs performance.

Tip:
Who now think about changing the SATA port in the BIOS from native / legacy IDE to AHCI, should first change for example only one part of the SATA port, where the drive with the operating system is not installed, if this is supported by the motherboard. Because if one like to save the new Windows installation, one must install the hard disk controller driver before changing SATA mode from IDE to AHCI – alternatively there are also Registry entries for it. If you like to upgrade from HDD to SSD, you should not copy the content 1:1 only with a tool like Norton Ghost or Acronis Backup. It is better to install a fresh Windows 7, Windows 8 or Windows 10 or adjust at least the SSD Alignment.

The AS SSD benchmark comparison results are extended with each new HDD/SSD test. Here you can see some SSDs in comparison to the Samsung SSD 850 Pro 128GB, and the graphic will be updated periodically with new SSD drives. At the moment the top of total AS SSD scores is lead from the Intel SSD 750 1.2TB PCIe SSD, followed by some soon added SSD RAID0 Benchmarks, then the Plextor M6e 256GB M.2 PCIe SSD, then some other SSDs and even before the OCZ Vector 180 480GB SSD joins the Samsung 850 Pro 128 GB SSD.

Here is a comparison of the AS SSD benchmark values, which are getting updated with new drives:

And here is an excerpt of the latest AS SSD benchmark results. For a better overview, they will be gradually replaced with latest drives:

ATTO disk benchmark results

The ATTO disk benchmark values gives a very good overview about the write and read rate on different file sizes. These values are maximum ratings, which are different to the previously continuous transfer rate benchmarks, since this benchmark may even reach a higher overall performance with slower SSDs.

With the Samsung SSD 850 Pro 128 GB is the read speed (green) at the smallest transfer size of approx. 0.5 KB higher than the write speed (red) and reaches the maximum read result of 569792 KB at a transfer size of 1024 KB.

Here is a screenshot of the ATTO Disk benchmark values (SATA3 AHCI):

The ATTO disk benchmark values are compared with a small transfer size of 32KB and a large transfer size of 8192KB. The bar chart already includes a comparison to some SSDs and HDDs, where the Samsung 850 Pro in ATTO can classify directly after the benchmarks of the RAID0 array consisting of several MX200 256GB SSDs.

CrystalDiskMark results

With CrystalDiskMark one receives a balanced measurement of the performance with different transfer sizes.

Here especially the 4K-64Threads values like before has relatively good sequential read values of 532.3 MB/s and write values of 484.0 MB/s.

Here is a screenshot of the CrystalDiskMark values (SATA3 AHCI):

The following diagram shows the CrystalDiskMark results again in comparison to the other SSDs and hard drives, which will be expanded step by step. In the CrystalDiskMark comparison one can see significant differences between the to-date tested of the Solid State Drives and Hard Disk Drives.

Here is a comparison of the CrystalDiskMark values, which are getting updated with soon coming drives:

And here is an excerpt of the latest CrystalDiskMark values will be gradually replaced with latest drives for clarity:

HD Tach results

With HD Tach one can measure the gradient of the performance, but the SSD transfer is not comparable with a conventional HDD. New logical NAND cell access of the SSD controller results like some other equal designed SSDs in strong varying values with the latest HD Tach Version 3.0.4.0 version, which is written for hard disk drives.

HD Tach shows the Samsung 128 GB 850 Pro SSD in AHCI mode at a continuous read rate with the lowest displayed access time display of approx. 0.0ms. And even the write operations shows continuous transfer rates of approx. 361.9 MB/s.

SiSoftware Sandra benchmark results

Of course, SiSoftware Sandra benchmark should not be missing in this test series. SiSoftware offers with their SiSoft Sandra program a very comprehensive tool, which contains a lot of tools to get very reliable test results of all hardware components.

The average access time of the Samsung SSD 850 Pro 128 GB is in SiSoftware Sandra with 24us extremely low and the drive index of 542.5 MB/s is already very high.

Here is a screenshot of the SiSoftware Sandra benchmark read values (SATA3 AHCI):

In the write performance measurement, the average access time of the Samsung SSD 850 Pro 128 GB in SiSoftware Sandra is also at extremely low 24us and the drive index reached relatively high 490.33 MB/s.

Here is a screenshot of the SiSoftware Sandra benchmark write values (SATA3 AHCI):
