Lexar 256GB Portable SSD Review

SSD manufacturers aren’t just content with manufacturing internal SSDs for consumers to use in the PCs, Macs, gaming consoles, etc. Now they have entered the portable storage market with a slew of options of portable SSDs. Lexar aren’t ones to be left out the race, they have designed and developed their own Lexar Portable SSD.

The Lexar 256GB Portable SSD which is powered by and is the newest addition to the Lexar Professional Workflow line of products will be the focal point for this review.

Capacities include 256GB and 512GB models

Lexar 256GB Portable SSD


About the size of a credit card and 1cm thick, Lexar have developed a really compact, and quite simple SSD that can easily fit into the palm of your hand, pants pocket, and any type of travel bags. Six LED lights grace the front of the device, with the blue LED on the far right indicating when the device is powered, and blinks when the device is in use. As well as five white LEDs indicating the remaining storage space left, the more LEDs on, the less storage space left. The device comes with a USB3 cable which is just over a metre long.


Overall Lexar haven’t revolutionised any new design techniques or styles, but rather chose to keep the design simple. When it comes to purchasing a portable storage device, most consumers would be putting more emphasis on storage capacity over design aesthetics of the device. But the inclusion of the LEDs to indicate remaining space is a fantastic addition that may sway consumers who are looking for a bit of pizzazz in their device.


The advantage that the solid state drive provides over traditional hard drives is that there are no moving parts, no rotating magnetic disks. This provides a quieter, and much more damage resilient device to protect against accidental data loss.


  • SSD-level performance—up to 450MB/s read and 245MB/s write speeds*
  • Sleek, compact design
  • LED capacity meter displays available storage space
  • Great for use with Lexar® Professional Workflow line products
  • Two-year limited warranty


Available in 256GB and 512GB storage capacities.


As always, to properly test whether a device meets expectations and lives up to the standards set, benchmarking and performance testing need to conducted. The portable SSD was plugged into a USB 3.0 port of a laptop PC using the cable provided in the package as to provide the most optimal and accurate results.

CrystalDiskMark 5.1.2


CrystalDiskMark achieved max reads speeds of 333MB/s and topped out at 245MB/s write speeds. The write speeds matched perfectly to the capabilities to which Lexar boasts. The read speeds were significantly lower than those suggested by Lexar. This can be attributed to the Lexar conducting tests in optimal settings to achieve their results.

AS SSD Benchmark 1.8


AS SSD Benchmark achieved greater read speeds of 388MB/s compared to CrystalDiskMark. The write speeds achieved 235MB/s.

ATTO Disk Benchmark


ATTO Disk Benchmark achieved greater read and write than the previous two benchmark programs in files over 512kb. Write speeds topped out at just below 250MB/s and read speeds of over 415MB/s. A big improvement over AS SSD and significant speed test results over CrystalDiskMark.

Real World Tests

Benchmark and performance testing is one thing. But testing how the drive works while transferring files in daily activity provides a better test of performance. Transferring a 10GB mkv file from laptop PC to the portable SSD achieved speeds of 85MB/s-95MB/s, averaging 90MB/s, completing the transfer in just over 1min45secs. Copying the same file from SSD to PC achieved speeds of 110MB/s.

While in use the device remained relatively cool, the only part of the device to increase in heat was the lower part, even then, the heat increase was extremely minimal and no reason for concern.

I encountered a problem when attempting to use the portable SSD with a WDTV Live media player.  The drive was not compatible with the drive. Looking on the WDTV website, the Lexar 256GB Portable SSD was not listed as a compatible device. However the device was compatible with the PlayStation 4, and performed exceptionally well.


The Lexar Portable SSD toughest sell is the low capacity space. Only available in 256GB and 512GB sizes, it will find it hard to compete with other traditional HDD portable storage options which offer greater sizes of up to 2GB at affordable prices. While also having to compete with other portable SSDs that are on the market such as the Samsung T1 and T3 which come in 250GB, 500GB, and 1TB capacities, and Sandisk Portable SSD T3 which comes in 480GB, 960GB, and 1.92TB capacities.

The biggest advantage that Lexar have is the price point. Costing $190 and $270 for the 256GB and 512GB respectively. Consumers who are already invested in the Lexar Professional Workflow range will find it easy to another product to their ecosystem.

The Lexar 256GB Portable SSD is an easy recommendation as it provides an affordable SSD solution to the needs of everyday use. Perfect for consumers who choose to use a compact device while travelling. Of course to those who work with larger capacity media files such as raw media files, or 4K media files, the 512GB model would be a better fit until Lexar releases a model with greater capacity.
