Crucial X8 1TB Portable SSD Review



Crucial X8 1TB Portable SSD Review



One of the biggest issues with data is the constantly growing amount of it we need, and the need to have it with us.

A byproduct of this is the need for speed. Those old USB 2.0 drives you had a few years ago are fine for a few documents, but transferring hundreds of gigabytes to or from them is something that takes seemingly eons in a time of instant data. Crucial gets around this problem by using the latest connectivity and internal architecture on its X8 series portable SSD. Capable of hitting transfer speeds of around 1GB a second, you don’t have to wait hours to take your large files along for the ride. It may even be faster than your internal storage! Taking advantage of USB’s faster 10gbps speeds and near-universal Type-C compatibility, the X8 can connect to anything and move data at your speed. Let’s take a little closer look and see how it does!

ProClockers would like to thank Crucial for sending us the 1TB version of the X8 SSD to check out!

Unboxing & A Closer Look

Crucial’s X8 comes in a small blue and white box with a Lifesize picture of the drive on the front. Capacity is noted in the lower right corner.

The rear of the box has basic info in a multitude of languages.

Inside the box, the X8 is contained inside a clear bag and lays in a plastic tray.

Under it, the USB cable, Type A adapter and a manual can be found.

The X8 drive itself is mostly anodized aluminum with two plastic end caps coated with a soft-touch coating.

The back of the drive looks similar but shows the capacity.

The included USB Type C cable looks pretty typical, but the Type-A adapter has a little tab sticking out of one corner than needs to made with the notch in the cable.

The adapter and cable both need to be aligned correctly for the cable to plug in all the way.

The adapter and cable both have a mark on one side to easily identify the correct orientation.


Crucial Storage Executive

This free downloadable tool enables your Crucial SSD to become even faster and allows it to get periodic updates so it’s constantly performing at its best. With Storage Executive, you can see how much storage (GB) you’ve used, download the latest firmware, monitor the drive’s temperature, reset your encryption password, and enable the Momentum Cache feature, which makes many SSD operations up to 10x faster.

The landing page shows system information such as system memory used, as well as info about each drive in the system, not just the X8.

When we hit the drive details button, we can dial in and see everything about the drive, including the firmware revision.

The SMART status tab shows a deep dive on drive statistics and health.

The next button would allow you to update the firmware if there was a new version available.

The sanitize and PSID revert options don’t really apply here thanks to the USB interface.

Momentum cache is almost pointless given how fast the drive already is, but you can enable system ram caching here if you want.

ATTO Disk Benchmark

“As the industry’s leading provider of high-performance storage & network connectivity products, ATTO has created a widely-accepted Disk Benchmark freeware utility to help measure storage system performance. As one of the top tools utilized in the industry, Disk Benchmark identifies performance in hard drives, solid-state drives, RAID arrays as well as connections to storage. Top drive manufacturers, like Hitachi, build and test every drive using the ATTO Disk Benchmark”

Atto gives us very close to the rated 1050MB/s on reads with writes only trailing slightly, off to a good start! This is really slamming the limits of 10gbps USB and every USB controller is different, so missing the 1050MB/s by less than 60MB/s is close enough.


CrystalDiskMark 6.0

“CrystalDiskMark is designed to quickly test the performance of your hard drives. Currently, the program allows measuring sequential and random read/write speeds.”

We see speeds just a hair slower than advertised but still one of the fastest USB drives we’ve seen.


Anvil’s Storage Utilities

Anvil’s Storage Utilities is a powerful tool that was designed in order to provide you with a simple means of assessing the read and write performance of your Solid State Drive or Hard Disk Drive.

The benchmark tool helps you monitor and check the response time of your unit as well as view the system information collected using Windows Management Instrumentation (WMI).

Anvil’s Storage Utilities has been designed to be the most comprehensive benchmark tool for Solid State Drives on the market. That does not mean that you can’t use it for conventional platter-based drives as well, but you do get the most out of the program when you test the speed and performance of SSDs with it. The program has gone through a series of beta and release candidate builds already and is currently available as Release Candidate 3. It is usually linked from this forum thread, which currently is not the case for the RC build which you can download here directly. You can’t use previous builds as they are set to expire automatically.

You can run a benchmark right away by selecting a drive from the menu at the top right or check out the settings first to make sure everything is configured correctly here. Here you can simulate a compression level of the test file, e.g. database, application or uncompressed, and whether you’d like to use the same test file on consecutive runs or generate a new one every time. As far as benchmarks go, you can run a standard SSD benchmark that is testing read, write, or both performances of the drive, or run threaded IO benchmarks only.

Anvil shows a little lower on the sequential speeds like normal but shows very fast response times (low latency) and manages the best score we’ve ever gotten on a USB drive.



The AS SSD benchmark determines the performance of Solid State Drives (SSD). The tool contains six synthetic and three copy tests.

The synthetic tests determine the sequential and random read and write performance of the SSD. These tests are carried out without using the operating system cache. In Seq-test the program measures how long it takes to read a 1 GB file to write respectively. 4K test the read and write performance is determined at random 4K blocks. The 4K-64 corresponds to the test Third 4K procedure except that the read and write operations are distributed to 64 threads. This test should SSDs pose with Native Command Queuing (NCQ), differences between the IDE operation mode where NCQ is not supported, and the AHCI mode. The additional compression test can measure the power of the SSD in response to the compressibility of the data. This is especially for the controllers that use to increase the performance and life of the cell compression, important.

In the first three synthetic tests and the compression test, the size of the test file 1 GB. Finally, the access time of the SSD is calculated, wherein the access to read over the entire capacity of the SSD (Full Stroke) is determined. The write access test, however, is done with a 1 GB big test file.

AS SSD uses a little different testing method but shows really good speeds.

The copy benchmarks really choke on the Program and Game segments for some reason. We tried rebooting, and about everything but kept getting the same results here. This is the only test we saw an anomaly in testing, so we’ll call it just that.

On the compression segment, we see sustained fast and stable read and write performance across the entire drive.

Final Thoughts & Conclusion

Crucial’s X8 portable SSD is a must-have for anyone that needs to keep a large amount of data with them, and can’t wait around all day for it to transfer from devices. In fact, the X8 is fast enough that you can work directly from it without having to transfer files to your computer first. With a world full of mobile content creators and professionals with large data sets, this will be a serious time saver. The USB Type-C interface makes it flexible enough to dance between all of your devices with ease, and the included Type-A adapter gives you near-complete compatibility.

Great job Crucial!
