Benchmark values and test results …
Let us now turn to the benchmark results. The test results for SATA3 drives are compared with an ASRock 890GX Extreme3 motherboard and the test results for mSATA and M.2 modules are performed with an ASRock Z97 Extreme6 motherboard and for USB 3.1 with an ASRock Z270 Taichi motherboard. Microsoft Windows 7 Ultimate Edition is currently being used as the operating system, and there are also tests with Windows 10.
The SSD drive speed was examined and compared with the following benchmark software:
AS SSD Benchmark – Download
ATTO Disk Benchmark – Download
CrystalDiskMark – Download
HD Tach – Download
SiSoftware Sandra – Download
The SSD benchmark results offers a very good reference point of the maximal possible reading and writing performance, the speed with smaller files and the respective access time. 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.
The Samsung T5 500GB Portable USB 3.1 SSD was able to achieve a high sequential read speed of 414.20 MB/s in Windows 7 and, despite the TLC Flash, also a high write speed of 423.52 MB/s. In AS SSD, the Samsung T5 500GB Portable USB 3.1 SSD achieves a very good overall score of 470 points.
The usable capacity of the Samsung T5 MU-PA500B SSD is 465.76 GB after over provisioning.
As mentioned on the previous page, we have tried to get everything out of the external USB 3.1 Gen2 SSD and have unofficially created tests with Windows 10. The Samsung T5 500GB Portable USB 3.1 SSD was able to achieve a read speed of 522.14 MB/s and a write speed of 498.63 MB/s in Windows 10. In AS SSD the Samsung T5 500GB Portable USB 3.1 SSD achieves a total score of 959 points!
The comparison of the AS SSD benchmark results is extended with each new HDD/SSD test. Here you can see some SSDs in comparison to the Samsung T5 500 GB Portable USB 3.1 SSD, and the chart will be updated periodically with new SSD drives. At the moment the top of total AS SSD scores is lead from the Samsung 960 Pro M.2 NMVe SSD and in Windows 7, the new Samsung Portable T5 USB 3.1 SSD with 512 GB joins the bottom field. This is a great result for an external USB drive.
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.
At the Samsung T5 500 GB Portable USB 3.1 SSD is the read speed (green) from a transfer size of about 64 KB higher than the write speed (red) and reaches the maximum read speed of 438006 KB at a transfer size of 512 KB. The new TLC V-NAND with 64 layers delivers an astonishingly smooth result, which we only know from MLC SSDs.
Unofficially, we have also created benchmarks with Windows 10. The Samsung T5 500GB Portable USB 3.1 SSD in Windows 10 achieves the maximum read values of 560538KB and the maximum write values of 534199KB with a transfer size of 512KB.
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, with this Samsung T5 500GB Portable USB 3.1 Gen2 SSD in ATTO in Windows 7 also placed at the bottom of the SSDs. The SSD as an external USB drive achieves a great result.
With CrystalDiskMark one receives a balanced measurement of the performance with different transfer sizes.
Here the Samsung Portable T5 512GB USB-C SSD reached sequential read values of 437.8 MB/s and write values of 451.4 MB/s.
The following diagram shows the CrystalDiskMark results once again compared with other SSDs and platter drives, which are extended 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.
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 varying rates with the latest HD Tach Version 126.96.36.199 version, which is written for hard disk drives.
HD Tach shows with the Samsung T5 500GB Portable USB 3.1 Gen2 SSD a very continuous transfer image with one of the lowest displayed access times of 0.1ms with the Samsung T5 500GB Portable USB 3.1 Gen2 SSD during the read and write processes. The strong peaks in the previously tested TLC SSDs’ write operations are still missing.
