Micron Crucial BX500 Review: Totally a Great Deal

Share what you're reading!

If you’re looking for a replacement solid-state drive (SSD) for your budget computer, here’s my recommendation: The Crucial BX500.

This drive takes SSD affordability to a new level. You can get the newly-released maximum capacity of 960GB for just $130, or about 13 cents per gigabyte.

There are also 480GB, 240GB, and 120GB capacities that cost accordingly less. Generally, the Crucial BX500 is about $5 to $10 cheaper than other entry-level SATA SSDs. (The drive will be avaible in higher capacities in the future.)

And there are no big catches. While far from the best, the drive’s performance is higher than my expectations and much faster than any hard drive. It also has enough endurance to last a long time.

That said, if you have a computer that still runs on a regular hard drive, upgrade it with the Crucial BX500 today, and you won’t be disappointed.

Crucial BX500: Built for affordability

Micron builds the new Crucial BX500 with specs optimized for low pricing. First off, it uses an affordable controller from Silicon Motion instead of a more expensive one from Marvell. Next, it uses Micron’s home-grown, low-cost, low-performance, 64-layer 3D TLC flash memory. And finally, the drive doesn’t have cache memory—it’s DRAM-less—nor does it support encryption.

That translates into one of the most affordable SSDs on the market. Since its launch a few months ago, the drive’s street price has dropped quite a bit.

Micron Crucial BX500’s hardware specifications.

As for design, the BX500 comes in the standard 2.5-inch form factor and supports SATA3, which caps at 6Gbps. As a result, it will work in most applications that need a regular SATA hard drive. Unlike the Crucial MX500 that came out earlier this year in both SATA and M.2 offerings, there’s no M.2 version of the BX500.

Mid-range endurance, useful features

Although the Crucial BX500 doesn’t have the highest endurance among SSDs, it’s slated to last a long time.

Specifically, you write 65 GB on the 480GB capacity per day and every day for five years before its endurance runs out. If you write less per day—and most of us indeed write significantly less—the drive will last even longer. It’s safe to say that the 480GB BX500 can last for tens of years on average use. The latest 960GB version has double the endurance.

The BX500 shares the same Storage Executive software as other Crucial SSDs.

The BX500 uses the same Micron Storage Executive software as other Crucial drives. The software allows you to monitor its status and customize its features, including Over-provisioning.

If you use it on a laptop, you can take advantage of its Momentum Cache feature, which uses the host computer system resources to boost the write speed of the SSD. Technically, Momentum Cache also works on desktops, but since there’s no battery, you risk losing unsaved data if the power goes out. 

The Crucial BX500 includes a re-branded, stripped-down Acronis True Image as its cloning software to make it easier for upgrades. While this software works, personally, though, I’d recommend the free version of Macrium Reflect.

Good performance

I tested the BX500’s 240GB, 480GB, and 960GB capacities. The 960GB performed slightly faster than the other two, but all three delivered excellent performance, considering the low cost. The charts below are of the 960GB version.

Crucial BX500 960GB Copy Score

The drive did pretty well in the copy (sequential) test, averaging 469MB/s and almost 530MB/s, respectively. When I made it do both writing and reading simultaneously, the drive now registered just some 230MB/s. In the random access test, the BX500’s low specs showed. The SSD landed below the average.

Still, in real-world anecdotal tests, the BX500 showed little difference compared to faster and more expensive SSDs. The computer booted up fast, taking just about 20 seconds, and most applications launched quickly.

In all, the BX500 is so much faster than any regular hard drive that the difference between its performance and other SATA SSDs’ is insignificant, especially for first-time users.

Good performance and endurance

Useful software and features


No encryption, bare-bone specs

The performance could use some improvement


With the Crucial BX500, Micron didn’t intend to wow anyone. However, this new SSD is a total winner thanks to its combination of low cost, good performance, and useful features, especially when you get the latest 960GB version.

If you’re looking for an affordable replacement SSD for a budget computer, you won’t go wrong with the Crucial BX500.

  1. i bought a couple of these one to upgrade a newer laptop with otherwise good specs like core i7 and 8Gb RAM. But HDD was a thin WD drive that was horribly slow. The Crucial SSD BX500 240Gb was just the ticket for a performance boost. I doubt the endurance specs will ever come into play and I also upgraded a older Dell with a spin drives as well to a BX 500 120Gb SSD. Again the performance evn on a older Haswell CPU was dramatic from the old spin drive. But I will say I found some user reviews that had these drives fail early some just weeks after installing. Did not look to be a significant problem, but probably does indicate some lemons in the mix.
