SanDisk Extreme 900 960GB Performance Benchmarks

CrystalDiskInfo is free benchmark that many people use to test storage drives with, but this test runs really quick and the results show the highest score of the five 'burst' tests for each performance metric tested. The problem is that the tests are so small and quick it rarely ever fills up a drives cache and is not a good look at real world performance on many external drives or SSDs that use TLC NAND Flash memory. We are including results for you to look at as you can use it at home to compare with to get an idea what the best case performance looks like on this drive. We topped out at a blistering 691 MB/s on the sequential read and 650 MB/s on the sequential write test, which impressive scores for an external SSD! ATTO Disk Benchmark showed that we were getting up to 793 MB/s read and 736 MB/s write speeds! These are the highest speeds that we have ever gotten through a USB 3.1 port! With the applications preset in Anvil's Storage Utilities we found sequential speeds of up to 712 MB/s Read and 649 MB/s Write! These are some of the fastest speeds that we have ever gotten through a USB port! 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 455-460 MB/s on average when the data was being written to the SanDisk Extreme 900 960GB drive. It took just 13.86 seconds to move almost 6GB of data over to the Extreme 900, which is amazing. The WD My Passport SSD 1TB managed to complete this task in 20.43 seconds and the Samsung SSD T3 2TB drive that is our lab file transferring work horse took 34.38 seconds! Temperatures on the SanDisk Extreme 900 960GB drive were found to be around 35C at idle and spiked up to 43C when we moved around about 20GB of data. Not bad temperatures and the enclosure gets warm during heavy period of use, but is never what we would consider hot. Let's wrap this up!

SanDisk Extreme 900 Portable SSD Conclusion

The SanDisk Extreme 900 Portable SSD 960GB model that we looked at today was wicked fast with speeds hitting 793 MB/s when reading data sequentially in the ATTO Disk Benchmark. The SanDisk Extreme 900 series is rated for speeds of up to 850MB/s Read/Write, so we came in a bit behind that on our particular test system. Real world performance is generally lower and we found that to be the case again for this drive, but we still managed to write data to the Extreme 900 at up to 460 MB/s. These are some impressive speeds and this is without a doubt one of the fastest drives on the market. It should be though as it is one of the first 10 Gbps USB 3.1 drives to come to market and has been targeted at those that want the fastest portable SSD around. SanDisk Extreme 900 Internal Diagram SanDisk was able to achieve these great speeds by using two SanDisk Ultra II 480GB TLC NAND based drives inside this enclosure that are run together in RAID 0. This might turn some people away, but that is what needed to be done to get theses speeds and it is these speeds that those working with large 4K video files and tons of high-res photos crave. It is also the reason that this external SSD is larger than many of the others on the market today.
