The secret sauce changes from one company to the next, but the underlying algorithms are closely guarded. Most SDDs utilize some type of SLC buffer, which is a designated portion of the NAND that runs in SLC mode (one bit per cell) to increase performance.

This is a new technique for Micron's NAND, but it provides similar protection to what we've seen with the MX series for many years.Ĭrucial's Data Write Acceleration (DWA) feature uses an SLC buffer to boost the performance of the TLC SSD. Micron has adjusted how it programs the upper and lower NAND pages to reduce the amount of power required to maintain signal integrity.

Encryption always runs in the background, but you have to enable TCG/Opal or the ATA Security command via the system BIOS to take full advantage of the AES-256 encryption engine.Ĭrucial still protects data at rest during a power fail event, but the new technique doesn't require surface-mounted capacitors on the PCB. The drives feature self-encrypting drive (SED) and full disk encryption (FDE). The MX series debuted back in 2014, and many of the core features carry over from the early models. Crucial lists the write performance as "up to," but that's also common in this era where advanced caching technology increases TLC NAND's performance with an SLC buffer. Random performance peaks at 95,000/90,000 read/write IOPS. The MX500's 560/512 MB/s of sequential read/write throughput is common for high-performance SATA SSDs. Micron's new 64-layer 3D NAND is the key component that should improve the picture on both fronts.Īll four capacities feature the same performance specifications. The same controllers often deliver better performance with Toshiba flash. We've also tested Micron's first-gen 32-layer 3D NAND paired with several different controllers over the last year, but it was very difficult to recommend any of the SSDs.

We've tested several products with the SM2258 controller paired with various types of NAND, but they weren't that impressive. The controller is an older model, but Crucial says its LDPC (Low-Density Parity-Check) error correction algorithms are powerful enough for the new 64-layer 3D NAND. We wrote a detailed preview of the SM2258's capabilities back in August of 2016. The MX500 uses the SMI SM2258 controller. The 2TB model will only ship in the 2.5" form factor while the 250GB, 500GB, and 1TB models will come in both 2.5" and single-sided M.2 2280. The Crucial MX500 will eventually come in four capacities and two form factors, but only the 1TB model will be available at launch. It isn't just the performance that links Crucial SSDs to products from companies you most likely have never heard of in some cases, the components inside the drives are identical. Some of Crucial's products even have similar performance to SSDs coming from tier-two and tier-three manufacturers.

Since then, Crucial's consumer SSDs have trailed the competition, and the performance gap between Crucial and other tier-one manufacturers has grown. We've felt let down by the company that introduced us to the C300, which was the world's first SATA 6Gbps SSD.
