The Crucial MX500 1TB SSD Review: Breaking The SATA Mold
by Billy Tallis on December 19, 2017 8:00 AM ESTConclusion
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 | |||
240-275GB | 480-525GB | 960-1050GB | |
Crucial MX500 | TBA | TBA | $259.99 (26¢/GB) |

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) |

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.

@Arnulf, Europe is a civilized land.sonny73n - Wednesday, December 20, 2017 - link
You remind me of the path I crossed with Samsung customer service about my 840 Evo (2 months old then).Dear valued customer,
Please contact your seller (Newegg)....
We acknowledged the issue. Please wait for firmware update....
The worst of all is that all their customer service reps don't know shit but they insisted to guide me, a veteran in IT field, how to install an SSD in my laptop. After firmware update, BSOD still happened but less frequent. Best thing I did was throwing that sucker in the trash.
Forget Shamesung and their shameless fanboys. This MX500 is a good deal but I prefer the BX300 because of MLC over TLC.

The BX300 is such an incredibly good drive. I've outfitted 20 office PC's with them since they were introduced, no problems whatsoever.ddrіver - Wednesday, December 20, 2017 - link
@sonny73n, I'll just repost this here: https://www.usenix.org/conference/fast16/technical...Short version: the difference between SLC and MLC is almost indistinguishable. Don't imagine that MLC vs. TLC will be a world of difference either. Not with new drives.

I had one of the worst warranty experiences ever with the 840 EVO years ago. Haven't given Samsung money since. OCZ and Mushkin, and Crucial for that matter, all have advanced RMA options and very smooth exchange processes. Crucial offers data recovery starting at $200.Samsung doesn't even return initial emails and they lie through their teeth on the phone, if you can even get ahold of the right person after being in a transfer loop for 30 minutes.

Recently??? Lol try well over 3 years ago. The 850 EVO's been using Samsung's V-NAND (V = vertical, as in 3D) pretty much since it's inception. In fact, they have used 3 (iirc) different types of V-NAND (differing in layer density) so far through production. You need to get with the program lol. Micron's slapping the EVO upside the head here, and I say that as someone who's bought more EVO's then I can count.lilmoe - Wednesday, December 20, 2017 - link
They just need to lower their damn price, and they'd still be good to go. Their 850 series is tried and proven, with a much better warranty, which is a significant advantage over newly released SATA models.Just cut the 850 Pro's price in half already Samsung.... I don't mind if they even cut the 10 year warranty in half dammit.

Agreed. Performance is pretty decent for a change! And having the 1TB available at the 250$ price point is also pretty aggressive as I'm sure it'll come down a stitch more in the next month or two.Samus - Wednesday, December 20, 2017 - link
The M550, MX100, MX200 and MX300 have always been decent contenders to Samsung 830, 840, 850 and 860, often priced lower and in the same performance bracket. Support and reliability are excellent.Chaitanya - Tuesday, December 19, 2017 - link
surprising crucial decided to keep mx line on tlc nand while bx was upgraded to mlc nand.
