SSD Prices to Halve With New JMicron Controller

It may be one the great whipping boys for SSD doubters but flash controller manufacturer JMicron claims it has come up with a breakthrough design which could see current prices slashed by up to 50 per cent...

Named the 'JMF612', the controller "uses an ARM9 core in a 289-ball TFBGA package, and will support the use of up to 256MB of DDR or DDR2 DRAM as an external cache". It will also work specifically with new 34nm and 32nm NAND, support Native Command Queuing (NCQ) to easy latency problems and even 128bit AES full disk encryption.

In practical terms, a USB port will be added so SSDs used as drives can easily accept new firmware while data integrity should improve with its ability to "correct up to 24 random bit errors per 1024 bytes". Finally no less than eight memory channels mean this could support SSDs with capacities in excess of 1TB.

Mass production will begin in July for SATA II based drives with the recently confirmed SATA 3.0 spec not coming into play until 2010.

Whether the new design is enough to restore consumer confidence after the horrendous stuttering issues which plagued the company's JMF602 controller and even its emergency fix, the JMF602B, is another matter entirely. That said, JMicron can look to Microsoft for inspiration. After all, Windows 7 seems to be doing a pretty good job easing the pain of Vista...

The reason why this allows for cheaper SSDs (or this 'breakthrough') is simply the fact that this controller can utilize NAND flash build on a 32/34 nm. process. That's pretty much all there is to it.

@Helmore more cynically, I'd also suggest that not needing to strap two together in a RAID array (how the shortcomings of the JMF602 were tackled) should also help with cost ;)

Theres gonna be a few things JMircron needs to resolved before peoples confidence with them is restored.

1. Stuttering

2. Peformance for a new drive and also used drive. Even though solid state drives do not require defragmentation, performance does degrade over time. Meaning a fully used solid state drive will suffer some nasty performance drops. The only way to regain that performance is to use the trim utlity to free up some page space in the solid hard drive.

The newer windows will have the trim feature in it, but until now, people will require the use of the trim utility now and then to get back their peak performance.

Also remember deleting data shortens the drives life span ..... triming will shoren it's life span :x so don't do it too often.
