Back in 2008 and 2009, JMicron was a relatively big name in the SSD industry. The industry as a whole was a small niche compared to what it is today and you could nearly count the players with the fingers on one hand. Neither SandForce nor Marvell were in the game yet, so SSD OEMs like OCZ and Patriot who didn't have their own controller technology mainly relied on JMicron for controllers. There were a couple of other options as well, such as Indilinx and Samsung, but the reason many OEMs found JMicron so alluring was the competitive pricing it offered. Since SSDs were very expensive in general, having a cheaper product than your competition meant a lot. For example, a 64GB JMicron-based OCZ Core was around $240 while Intel asked $390 for their 80GB X25-M, so the advantage JMicron provided was much more than just a few bucks.

But the pricing had its dark side: to put it bluntly, the performance was awful. The JMF602 was so bad that the drives would pause for several seconds before becoming responsive again under normal desktop use, which was completely unacceptable given that users were paying several dollars per gigabyte. Obviously, that left a bad taste of JMicron to everyone's mouth. The OEMs were not happy because reviewers were giving them a hard time. and the buyers were not exactly satisfied either. During the worst times we had major difficulties getting any JMicron based SSDs for review because Anand had been frank and said that the drives should never have hit the retail in the first place. It was hard for the OEMs to blame JMicron because ultimately it was their decision to utilize JMicron's controllers. They had validated the drives and found them good enough for retail.

When SandForce introduced its first generation controllers in late 2009, the game totally changed. Similar to JMicron, SandForce did not sell any SSDs. Sandforce sold the controller, firmware and software as a single stack to the SSD manufacturers who would then do the assembly. The difference was that SandForce's controller could challenge Intel and provide a user experience that was worth the money. Unsurprisingly many SSD OEMs decided to ditch JMicron and go with SandForce because SandForce simply had a better product. As a result, JMicron started to fade away from the market. Sure there were still OEMs that used their controllers in some of their products but the days of JMicron being the go-to company for controllers were over. 

JMicron tried to get back into the game, and it did release new and better SATA 3Gbps controllers (such as the JMF618 found in some Kingston and Toshiba SSDs) but SandForce had quickly taken a lion share of the market and the industry as a whole was already preparing for SATA 6Gbps. JMicron's roadmaps showed that a SATA 6Gbps JMF66x series was planned for the second half of 2010, which made sense given that Intel was integrating SATA 6Gbps to their 6-series chipsets in early 2011. But for some reason, the JMF66x never made it to the market on time. 

Now, over three years later, JMicron is looking to make a comeback with its new flagship SATA 6Gbps controller, the JMF667H.

    Looks like a great product for last year. This might help JMicron capture some of the OEM market - maybe even some budget enthusiast SSDs. What JMicron didn't do was swoop in with a M2 x4 PCIExpress controller. I'm done with 6Gbps SATA. Reply

    Ahhhh.... JMicron - like a phoenix from the ashes. Fool me once, shame on you. Fool me twice...

    Oh well, someone has to be at the bottom of the barrel.

    I guess their selling point would be that they're cheaper than the Crucial M500. So if pricing is all-important to you (and why are you buying a SSD if price is all-important), then they would be a contender. Reply

    "The JMF667H is not perfect and there are a couple of things I would like to see. The first one is support for TCG Opal 2.0 and IEEE-1667 encryption standards."

    IEEE-1667 is not an encryption standard. Perhaps you meant IEEE-1619

    Nope. IEEE-1667 is for storage devices, at least the version I'm looking at.

    Yes, it is authentication and discovery for storage devices (particularly removable/portable ones). It says nothing about encryption. Reply

    IEEE-1667 is a requirement for Microsofts Bitlocker eDrive, which is encryption. Reply

    Contrary to the history given in the introduction, it was with the the Indilinx "barefoot" controller that was the game changer. Once Indrilinx entered the market, SSD's based on the J-Micron controller could only be sold to consumers who didn't understand what they were buying. The name J-Micron became toxic because if you wanted to advise somebody on buying an SSD, your first and last words would be, "whatever you do, don't buy and SSD with a J-Micron controller."

    In contrast, Sandforce's first generation controller was an incremental improvement over what came before it. There's nothing wrong with that, but the term "game changer" doesn't apply.

    Seems like that early history explanation really misses the point that Indilinx was the first real competition to Intel back then.

    Sandforce came along and was the first company to put Intel down. But Indilinx was the first company that convinced people they could live with non-Intel SSD's and not... be JMicron'ed.
