The Crucial MX500 1TB SSD Review: Breaking The SATA Mold

Most of the time, it seems like all the interesting new developments in the SSD market are in the NVMe segment, while SATA SSDs are stuck with the same performance limits and decreasing endurance. The Crucial MX500 bucks the trend by setting several surprising performance records while offering competitive mainstream pricing.

The MX500 is a more well-rounded product than its predecessor, the Crucial MX300. The MX300’s performance takes a serious hit when it is full or subjected to heavy write loads, but the MX500 retains much more of its performance and does a better job of keeping latency under control. It is still subject to some of the pitfalls of TLC NAND with SLC write caching, but they are mitigated about as well as on any of its competitors.

Several of our synthetic benchmarks returned results for the MX500 that are far above any previous SATA SSD we’ve tested. The Crucial MX500 is faster at handling short bursts of I/O than any of its competitors, and even outperforms some NVMe drives with MLC NAND. This is exactly the kind of performance that a consumer SSD should focus on: increasing responsiveness, rather than trying to get a high score on a benchmark of throughput with queue depths that consumer workloads never hit.

These optimizations translate into some of the highest average data rates on our ATSB Heavy and Light test that we’ve seen from a SATA SSD. In favorable conditions (which also happen to be the most common and realistic) of a drive that isn’t full and does get TRIM commands from the OS, the MX500 will generally hold its own against any other SATA drive. It isn’t at the top of every benchmark—under sustained I/O it isn’t any faster than most of its current-generation competition. But for most users, there’s no need to pay any extra for the performance of a Samsung drive.

The MX500’s power management seems to have taken a step backwards from the impressively efficient MX300. The MX500 is still a reasonable option even for mobile use, but it’s a bit disappointing to see that Micron had to sacrifice efficiency on almost every test to improve performance on most of them. The MX500’s idle power consumption is also a bit higher than the MX300, but not enough that we worry about something being broken. (It’s also possible that our new power measurement equipment is contributing to higher readings; we’ll rule out such potential discrepancies over coming weeks by re-testing the back catalog of drives.)

The Crucial MX500 does not stand out as being the top SATA SSD, but it is clearly a top-tier choice. Micron has extended the warranty to 5 years and increased the write endurance rating to match. The performance and power consumption of the Crucial MX500 are suitable for almost every consumer use case. We look forward to the rest of the capacities arriving next year.

SATA SSD Price Comparison

Crucial MX300 $89. 99 (33¢/GB) $139.99 (27¢/GB) $272.00 (26¢/GB)
Samsung 850 EVO $84.99 (34¢/GB) $139.99 (28¢/GB) $289.99 (29¢/GB)
Samsung 850 PRO $109.99 (43¢/GB) $223.42 (44¢/GB) $399.99 (39¢/GB)
SanDisk Ultra 3D $79.99 (32¢/GB) $139.99 (28¢/GB) $279.99 (28¢/GB)

Toshiba TR200 $74.99 (31¢/GB) Out of Stock Out of Stock
Intel 545s $99.99 (39¢/GB) $171.99 (34¢/GB)  

In terms of performance, the SATA drive to beat has long been the Samsung 850 PRO, but its much cheaper sibling the 850 EVO also offers great performance in most use cases and is the most important competitor for mainstream SSDs. The 1TB Samsung 850 EVO is currently selling for $289.99. With the MX500 arriving at $259.99 for the same capacity but with a longer warranty, higher everyday performance and better power efficiency, Samsung needs to change something. The rest of the industry will also have to respond, because the MX500’s MSRP is beating the holiday street prices on competitors like the SanDisk Ultra 3D.

The NAND flash shortage is starting to ease as everybody (except SK Hynix) ramps up their 64-layer 3D NAND production. By setting an aggressive introductory price, it is clear that Micron expects SSD prices to be in decline, and they intend for the MX500 to remain an economical choice for the near future. If they can keep the MX500 ahead of the pace of price drops, they have a good chance at recapturing the broad market appeal that once made the MX100 such a clear-cut recommendation. Given how the recent Crucial BX300 is also aggressively positioned, they are probably going to keep up the pressure.

Hardware, Tips and Tricks

When you are looking to buy a new SSD and you are looking for a good performance / performance / price ratio, for sure the first two brands that come to mind will be Crucial and Samsung and that is that their SSDs are always in the top lists sales. Today we are going to do technical comparison of two of these top selling SSDs: Decisive MX500 vs Samsung 860 EVO to determine which one is technically better and which one is worth buying.

Both devices are available in the same format and capacities, and at very affordable prices given their power. If we take the currently best-selling 1TB versions as an example, these are their non-offer selling prices:

As you can see, the price difference between them is only about 20 euros, which should put the Samsung SSD, which costs more, and theoretically better. But is it really so? Let’s check it out.

Many manufacturers can vary read and write speeds depending on capacity, but this does not apply to these two SSDs, so it seems to us that they are not even painted to be able to make a technical comparison. In this case, the Crucial SSD is a little higher in terms of read speed, but Samsung in writing takes the same advantage that Samsung uses in this area, so in terms of theoretical performance, we can say that they are is practically related to .

If Samsung uses relative advantages, that means the maximum capacity it offers, given that the Crucial MX500 can only be found in capacities up to 2 TB, while Samsung 860 EVO is offered in capacities up to 4 TB double In terms of durability, Samsung SSD takes the lead again, which thanks to V-NAND technology provides unparalleled durability, although in terms of warranty, both are backed by 5 years .

We are going to analyze the technologies that both SSDs support.

Critical MX500

  • Dynamic write acceleration.
  • Redundant independent NAND array (RAIN).
  • Adaptive thermal protection.
  • Integrated immunity to energy loss.
  • Device sleep support (DevSleep).
  • Active garbage collection.
  • TRIM support
  • Self Testing and Reporting Technology (SMART).
  • Error correction code (ECC).
  • Multi-step data integrity algorithm.

Samsung 860 EVO

  • TurboWrite intelligent technology.
  • Error Correction Code (ECC).
  • Data integrity algorithm.
  • Active garbage collection.
  • TRIM support
  • 1 GB cache.
  • DevSleep.
  • 256-bit AES, TCG Opal and IEEE 1667 encryption.

Again, we find that both SSDs are quite technologically advanced. Crucial’s SSD takes some advantage with its built-in power loss protection, but that’s something Samsung’s SSDs also have, though they don’t point it out as it has 1GB of cache, just to protect data in the event of a power loss.
