Lexar SL660 BLAZE Gaming Portable 1TB SSD Review

Today, we’ll be taking a quick look at the Lexar SL660 BLAZE Gaming Portable 1TB SSD. It’s a portable gaming SSD designed for gamers and content creators on the move, and uses the latest USB 3.2 Gen 2×2 (Type-C) interface that supports speeds of up to 20Gb/s. It offers ultra-fast read speeds of up to 2,000 MB/s, with a write speed of up to 1900 MB/sec. It’s perfect for transferring large-sized data including 4K videos, high-resolution photos, games, film, music, data backup and more.

Our review sample comes with a total capacity of 1TB which is a decent size for an external and portable SSD. It’s extremely compact and light-weight measuring only 57.4 x 112.6 x 10.6mm, and weighing in at only 80g. This portable SSD features RGB LEDs to create a lively atmosphere rendering your gameplay more dynamic. It also also a premium aluminum enclosure with a sandblasted finish for added protection against shock and vibration.



Before we go further, I have to make a really important point about the USB 3.2 Gen 2×2 (20Gbps) interface. Not all motherboards and PCs support USB 3.2 Gen 2×2. Most will have native support for USB 3.2 Gen 2 (10Gbps) but NOT USB 3.2 Gen 2×2 (notice the difference between Gen 2 and Gen2x2). If your motherboard or PC do support USB 3.2 Gen 2×2 (20Gbps), then it’s usually on the front USB and it requires a special 20-pin USB Type-E cable which connects to the motherboard (see below). Once you have this connected, you will be able to take full advantage of the speeds offered by the USB 3.2 Gen 2×2 (20Gbps) interface.


Confused and NAND flash memory? Well, there are several types of NAND flash memory used in most of today’s SSDs. The two most popular are SLC and MLC, and now TLC. Here’s a little background taken from HowToGeek.

You can also check out the various types of USB standards via the chart below. In this case, you should be looking at the 5th column.


I would like to send a big thank you to Lexar for the review sample! Here is a snippet of what they have to say about themselves on their website:

Since establishment, Lexar has worked diligently to bring unparalleled value to our customers. We define value as providing well-designed, innovated, and user-friendly products that meet the expectations of customers and enterprises looking for memory solutions to count on.

The Lexar Quality Labs are a group of testing facilities where all Lexar memory card, card reader, and USB flash drives undergo extensive testing to ensure performance, quality, compatibility, and reliability. This provides customers with the highest level of confidence when using Lexar products to capture, manage, move, and store the memories that matter.

We have a team of dedicated lab technicians that test Lexar products with more than 1,100 intended digital devices, including:

  • DSLR and point-and-shoot cameras

  • Desktop, laptop, and tablet computers
  • Card readers

In addition to device compatibility testing, technicians in the Lexar Quality Labs also test products for durability by putting them through various vibration, temperature, electric shock, impact, and strength tests. This rigorous testing ensures all Lexar products offer the quality and reliability customers have come to expect from Lexar.


Since I don’t have a laptop with USB 3.2 Gen 2×2 Type-C ports, we will be testing the Lexar SL660 BLAZE portable gaming SSD using our test rig which is comprised of an ASRock Z690 Taichi RAZER Edition motherboard powered by an Intel Core i9-1200KF processor. The motherboard features the USB 3.2 Gen2x2 Type-E port, so in the end I managed to get hold of the correct cable (Type-E to Type-C). I’m expecting excellent read/write speeds as advertised, so let’s hope the USB 3.2 Gen 2×2 (20Gbps) interface does the job.
