REAL WORLD FILE TRANSFER COMPARISON
For our Real World File Transfer Comparison, we have included the SanDisk Extreme Pro and WD Black 1TB NVMe SSDs, Samsung 960 Pro, HP EX920, Toshiba OCZ RD400, both Samsung 970 EVO SSDs, and the HP EX900 NVMe SSD in our testing with the Samsung 970 Pro 1TB NVMe M.2 SSD. This test is conducted through the transfer of data from one spot on the test drive to another to give us the truest of transfer speed results for that device.
Although we would like to have seen our OS transfer time equal that of the previous gen 960 Pro, the Samsung 970 Pro had the best overall performance and its video transfer time was off the chart, moving 15GB of videos in seven seconds. Quite frankly, we never believed this and did same on three different systems in order to validate.
The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec.
REPORT SUMMARY AND FINAL THOUGHTS
Let’s start this summary by putting into perspective just how well the Samsung 970 Pro 1TBV NVMe SSD performed in our rather lengthy test regimen. For a SSD to do well in testing, we might expect it to excel at most of these tests. For it to be looked at as one of the best, we might count on it being the best we have seen at one or two of the tests. In our testing over the past few days, The Samsung 970 Pro 1TB NVMe SSD has proven to be the best at every test we threw at it, most of these tests by a healthy margin.
Take our PCMark Vantage Storage 2.0 result for instance. Prior non-Samsung M.2 SSDs (still excluding the Intel Optane) reached a high average transfer speed of 701MB/s where the 970 Pro reached 839MB/s. Actually we have to hand it to Samsung for having both previous generation Pro models hold both spots directly below the 970 Pro. This followed suit in PCMark Extended testing where all M.2 SSDs are pushed into steady state and Samsung still held a commanding 200MB/s margin over the rest of the field. The Samsung 970 Pro gave us 3.5GB/s read and 2.7GB/s write as specified but we saw write IOPS well above the specified 500K at 591,427 random 4K IOPS.
We have to credit Samsung at retaining the Pro line with 2-Bit MLC V-NAND and, at least in our opinion, this could be the reason that the Samsung 900 Series Pro line enjoys the best reputation in the business, with a 5-year limited warranty. One might think that the only bump in the road might be retail pricing of $329.99 (512GB) and $629.99 (1TB) as this SSD peaks at $269 above the HP EX920 1TB SSD right now at Amazon and is $180 higher than the WD Black 1TB NVMe SSD also available and $449 at Amazon…. but we don’t think so. The reigning champion Samsung 960 Pro 1TB NVMe SSD is available at only $15 less than the 970 Pro (remember May availability date) we are reviewing today and the 960 Pro is one of the top sellers in the business. Editor’s Choice to the Samsung 970 Pro NVMe SSD. You have done it again Samsung!
