SanDisk 1TB Extreme Portable SSD Review
SanDisk Extreme Portable SSD Performance Benchmarks
To benchmark the SanDisk Extreme 1TB Portable SSD we’ll be using CrystalDiskMark, ATTO Disk Benchmark, Anvil’s Storage Utilities, AJA System Test, and a manual file transfer test. These five benchmarks should paint a good overall picture of how this portable SSD performs, so you know what kind of performance to expect before making a purchase that could be up to $630.
SanDisk Extreme 1TB Portable SSD CrystalDiskMark:
When it comes to sequential read/write performance we topped out at just shy of 560 MB/s read and right around 500 MB/s write on the 1TB model that we tested. Not bad and exceeds the series rated speeds of up to 550MB/s read speeds and up to 500 MB/s write speeds.
SanDisk Extreme 1TB Portable SSD ATTO:
ATTO Disk Benchmark showed that we were getting up to 562 MB/s read and 527 MB/s write speeds on the SanDisk 1TB Extreme Portable SSD through the USB 3.1 Type-C port on our Dell XPS 13 laptop.
SanDisk Extreme 1TB Portable SSD Anvil:
Anvil’s Storage Utilities benchmark finished with an overall score of 2,818.89 points on the SanDisk Extreme 1TB Portable SSD with no modifications to Windows 10. The sequential read speeds were 482 MB/s and the sequential write speeds were 443 MB/s. Random 4K read/write performance isn’t that important on a secondary drive, but some will likely try using this as a boot drive at some point in time. We are seeing 21/39 MB/s Random 4K read/write speeds on this portable drive, which is pretty solid.
SanDisk Extreme 1TB Portable SSD AJA System Test:
AJA System Test by AJA Video Systems measures system disk performance using video test files of different resolutions, sizes and codecs. We selected the standard 4K UltraHD resolution, a test file size of 1GB and the ProRes 4444 codec to see how this drive does with regard to video rendering performance. ProRes 4444 is used for heavy effects work and deep color projects. FPS is very important for this market as well as MB/s, so we’ll be talking about both FPS and MB/s performance here. The first lets the editor know whether they are going to be able to make their 60p project work for instance. The second they value for understanding rendering expectations, throughput, file read/write expectations for transfers and that kind of thing.
We we able to get 502 MB/s read and 472 MB/s write from the SanDisk Extreme 1TB portable drive on this benchmark test. This translates to 84 Frames Per Second (FPS) on read and nearly 79 FPS on write! The SanDisk Extreme Portable SSD will allow you to move hi-resolution photos and videos fast, but you can also work off the drive if needed.
SanDisk Extreme 1TB Portable SSD File Transfer Test:
We wanted to do some real world file transfers, so we copied over few MKV Full-HD movie that added up to almost 6GB. During the transfer we found that we were getting around 340 MB/s on average when the data was being written to the drive.
It took 17.544 seconds to transfer the files over and that is on par with the Samsung Portable SSD T5 series that is one of the SanDisk Extreme Portable SSDs main competitors. The SanDisk Extreme 900 960GB drive (review) was found to be 21% quicker on this file test. SanDisk recommends the SanDisk Extreme 900 series for those that shoot 4K, 5K or 8K video and the Extreme Portable SSD series is for those that are shooting 1080P or less due to this performance difference.
