The State Of Solid State: Computex 2015

Silicon Motion

Silicon Motion is a company on the move. It has several recent design wins to supply controllers to large NAND flash fabs that sell SSDs in large volumes. SanDisk and Crucial already have products on the market, and it's rumored that Intel will release a product with a Silicon Motion controller soon. 

The SM2246EN processor ships in Crucial's BX100 as well as other products. Moreover, the new SM2246XT four-channel DRAM-less design was just announced for SanDisk's Z400s. And prior to Computex we detailed the successor to the SM2246EN, the SM2256. It was designed for three-bit-per-cell flash. 

Silicon Motion's next step is to move into the PCIe arena. The SM2260 is a four-lane PCIe 3.0 controller designed to support MLC and TLC flash. Performance should be around 2200 MB/s sequential read and 1000 MB/s sequential write speeds. To date, most of Silicon Motion's controllers have been four-channel designs; this may be the company's first eight-channel effort. If so, capacity could double in M.2 22110 form factor products.

    The time is ripe to change your old spinning catastrophe and embrace the now of SSD.

    So have they fixed the data loss if not connected to electricity for more than a week thing?

    Spinning catastrophe? My hdd doesn't perform much slower than my ssd for 90% of tasks, the biggest improvement was installing windows. For that I was impressed. An hdd shouldn't be a catastrophe, if it is I'd strongly suggest a better brand/model. Installed an ssd on a workstation and of all the upgrades it was the component I was least happy with. The new cpu and ram upgrade were by far more impressive. Not that I'm 'unhappy' with it, it is a little snappier though not enough to make me rush right out to buy another one for my other rig. If another 240gb ssd goes on sale for $60 like the first one I bought I might consider it. Pcie m.2 look appealing and great on paper but I suppose it would be of greater benefit to someone who is suffering a bottlenecked system due to storage in the first place.

    Yes, about 5 years ago.
    SSDs are still no archival media, and they will corrupt after a year or two without power. But if you are the sort of person who travels a lot and unplugs your PC for 2-3 months at a time then it is not a real concern anymore.

    I'm so out of touch that I didn't even know that was "a thing"

    O.o

    Really? 5 years ago? Because I've gone on vacation for about a month and my Windows wont even start anymore. And that was about a year ago. Heard a rumor that the 3D stacking technology thing managed to eliminate this problem and i was waiting for some more good news about that before buying a new SSD.

    A $60 240GB SSD is the reason why you don't feel a big performance increase over your HDD.

    But how old was the SSD? The model, not the particular one that you own.

    It was on sale. At the time, ocz vector 150's were going for $180. It stays neck and neck with the samsung 840 evo (850's weren't even available yet) and the two trade blows a bit. The vector 150 has slightly slower random reads and the samsung has slightly slower write speeds. It was chosen for a workstation doing content creation with larger files where write speed was preferred. Maybe people feel such a huge difference over their hdd's because they're using junk hdd's? My wd re4 gives me no issues. The only time aside from bootup that ssd's seem to have a huge performance gain is during testing where a longer sustained data transfer is occurring. Something most people won't encounter under normal use of a pc, instead it will more than likely operate in small bursts. So technically, it was a $180 ssd using the newer 19nm toshiba nand. Hardly a junk ssd.

    When you said it I was thinking something along the lines of a V300 with async flash.
