Final Words

The value-oriented segment of the SSD market has a lot of great options at the moment for drives that don't have any critical weaknesses or major compromises relative to high-end SATA drives. This means that buying decisions will be driven almost entirely by the pricing of the moment. If priced properly, the Plextor M6V can be a great choice for general-purpose consumer use and especially for mobile use.

From a technical perspective, the most interesting aspect of the M6V is its Toshiba 15nm MLC NAND, as this is the only SM2246EN-based drive using it. Toshiba's 15nm MLC NAND seems to be a bit slower than the Micron 16nm MLC used in its closest relatives/competitors, but at the same time the M6V uses a bit less power. These differences are measurable, but probably not meaningful in the real world. The Plextor M6V and Crucial BX100 are about as close to interchangeable as drives can be without being clones that differ by only their label. The BX100's partial power loss protection may be important to some consumers but it's usually not a requirement in this market segment, and SM2246EN drives have not had any notable reliability issues.

Amazon Price Comparison (10/12/2015)
Drive 120/128GB 240/250/256GB 500/512GB 960GB/1TB
ADATA Premier SP610 $49.99 $84.99 $223.44 $379.99
Transcend SSD 370 $57.99 $89.99 $169.99 $328.46
Mushkin Reactor - - - $353.99
Crucial BX100 $61.99 $79.99 $159.99 $314.99
Plextor M6V $65.99 $99.99 $189.99 -
OCZ Trion 100 $59.95 $75.00 $158.99 $349.90
Samsung 850 EVO $64.00 $89.24 $168.63 $343.24

Unfortunately, the current pricing on the Plextor M6V is simply too high in a crowded market. It's undercut by the Crucial BX100 and Samsung 850 EVO at every capacity point, and even the older SM2246EN drives using 20nm MLC are cheaper. Crucial and Samsung have the advantage of in-house NAND manufacturing, but the other competitors are just as much at the mercy of their NAND supplier as Plextor. In the long run the Toshiba 15nm MLC in the M6V ought to allow Plextor to beat ADATA and Transcend on price thanks to its greater density, but at these prices Toshiba and Plextor aren't there yet.

Ultimately if the high price is due to limited supply of the 15nm MLC, there may be significant price cuts further down the road as they get production ironed out. For now, although the M6V is as solid as any of the other SM2246EN drives, overall the BX100 remains the better value. Otherwise Plextor still has a hand to play in the market for smaller form factors; if the mSATA and M.2 variants of the M6V show up along with more reasonable pricing, they'll be very compelling for power-sensitive uses, as the BX100 is only available in the 2.5" form factor.

    Yet another new SSD article on AT that ends up showing how it gets destroyed by Samsung in overall specs/price. Reply

    Actually the Crucial BX100 is a better choice looking at the scores. Reply

    Nope, not to note it isn't even present on many screens and MX200 is a different product. Reply

    The BX series is better bang for the buck, you won't notice the speed difference with the popular samsung drives. Reply

    I rather go with AMD Radeon R7 series. Its one of the highly rated high drives in the market (see http://www.consumerrunner.com/top-10-best-hard-dri... for example) Reply

    Assuming this is a low-end drive i.e. cheaper than the 850 pro, it looks like it outperforms the 850 evo mSata pretty much across the board, getting close to crucial's BX100. Reply

    As an owner of 2x840 EVO and 2xPlextor, I can tell you the Samsung's bug was a major disappointment. Read performance after months simply sucks and I had to patch the firmware 2-3 times and regularly "manually" freshen the data with the samsung tool. I have way more confidence in the Plextor firmware. Never again Samsung. Reply

    ...yet another SSD article on AT that focuses on the pointlessness of non-real world benchmarks. Readers will leave this article without having a clue what boot time differences to expect between drives, or any other metric. I've been saying this for years. HardOCP finally caught on. http://tinyurl.com/pvyzmau Reply

    What is the purpose of reviewing SATA SSD drives? Anyone in the market for a drive should either buy a spinning HDD for storage or a PCIe for speed. Reply
