Lexar SL660 Blaze Gaming Portable SSD Review (1TB)


Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.




Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.


TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features. Advanced load bench-marking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.

Last but not least, we wanted to know if there would be any drop whatsoever moving data to the disk and moved an 85GB 8K media file where we saw the data transfer remain at 1GB/s throughout.  We repeated immediately with the same result.


Credit where credit is due with respect to Lexar’s vision of the SL660 Blaze Gaming Portable SSD.  Most portable SSDs that we get have that rubber build/feel and, as much as they are great gear, they aren’t this Blaze.  It’s is well shaped with an LED  ‘D’ ring integrated and the shell is a graphite grey sandblasted aluminum build.  Available in both 512GB and 1TB, we have to admit that larger capacities would be great but their market research knows what sells.

Performance is as expected and just a reminder that to get 20Gbps speeds of 2GB/s, one needs a PC or laptop that is equipped with USB 3.2 2×2.  As a photo enthusiast who moves a great deal of data from my camera to PC daily, I have both Thunderbolt 3/4 and USB 3.2 2×2 available and find that I am always using my 20Gbps external CFExpress B reader.  It seems that USB 3.2 is much more user friendly with today’s systems, as is the 20Gbps 2×2 bonus.  Pricing is excellent for this SSD, as is the 5-year warranty. Gold Seal!
