Introduction, Specifications and Packaging
Last week, Samsung flew myself and a few of my fellow peers in the storage review community out to Seoul, Korea. The event was the 2012 Samsung SSD Global Summit:
At this event, Samsung officially announced their new 840 Pro, which we were able to obtain early under NDA and therefore publish in concert with the announcement. The 840 Pro was largely an incremental inprovement over their 830 Series. Newer, faster flash coupled with a higher clocked controller did well to improve on an already excellent product.
As the event closed, we were presented with the second model of the lineup - the 840. This model, sans the 'Pro' moniker, is meant more for general consumer usage. The first mass marketed SSD to use Triple Level Cell (TLC) flash, it sacrifices some write speed and long-term reliability in favor of what should become considerably lower cost/GB as production ramps up to full capacity. TLC flash is the next step beyond MLC, which is in turn a step after SLC. Here's a graphic to demonstrate:

Allyn wasn't the only one blown away by the performance and efficiency increase of the new Samsung 840 Pro 512GB SSD, anyone who had a chance to review this drive saw incredible performance. It is not yet available for purchase but you can expect to see the 256G at $270 and this 512GB at around $600 when they do become available. Inside the 3-core eight channel MDX controller is paired with eight 64GB modules of Samsung’s new 21nm MLC DDR-2 toggle mode NAND, which give this drive its incredible speed. SSD Reviews came to the same conclusion that Al did, we need a new interface as SATA 6Gb/s is already being saturated by high end SSDs.
"Our report on the Samsung 840 Pro SSD begins post take off from Pearson Int’l Airport in Toronto and on route to Seoul, South Korea. Having had this SSD in our hands for some time, even the enormity of the Samsung 840 family release celebration cannot overshadow the performance of what just might be the hottest solid state drive to hit the streets to date. How does just under an extra hour laptop life and 100,000 IOPS grab you to start?"

Introduction, Specifications and Packaging
Samsung has been at this SSD thing for quite some time now. The first SSD I bought was in fact a Samsung unit meant for an ultraportable laptop. Getting it into my desktop was a hack and a half, involving a ZIF to IDE adapter, which then passed through yet another adapter to convert to SATA. The drive was wicked fast at the time, and while it handily slaughtered my RAID-0 pair of 74GB VelociRaptors in random reads, any writes caused serious stuttering of the drive, and therefore the entire OS. I was clearly using the drive outside of its intended use, but hey, I was an early adopter.
Several SSDs later came the Intel X25-M. It was a great drive, but in its earliest form was not without fault. Luckily, these kinks were worked out industry-wide, and everyone quickly accelerated their firmware optimizations as to better handle random writes. Samsung took a few generations to get this under control. The first to truly get over this hump was the 830 Series, which launched earlier this year. It utilized a triple core Arm 9 CPU which was able to effectively brute force heavy random write workloads. It also significantly increased the speed and nimbleness of the 830 across the board, which combined with Samsung's excellent reliability record, quickly made it my most recommended series as of late.
...and now we have the 840 Series, which launched today. Well, technically it launched yesterday if you're reading from the USA. Here in Korea the launch started at 10 AM and spanned a day of product press briefings leading to the product NDA expiration at 8 PM Korea time. This review will focus on the 512GB capacity of the 840 Pro model. We will follow on with the 840 (non-pro) at a later date:

Good morning from Seoul, Korea!
I'm here at the Samsung Global SSD Summit, where Samsung has officially launched their 840 Series of SSDs. This new controller features many advancements which enable it to climb past 100,000 IOPS in random reads (!!!). Samsung also claims peaks of 90,000 IOPS in random writes. These are seriously high numbers for any SATA SSD, and we will be publishing our full review of the 840 Pro once the NDA lifts later this evening (tomorrow morning for everyone back in the states).
Unfortunately there is nothing more I can disclose at this time, but stay tuned for more info! While all of you are sleeping tonight, I will be attending several briefings covering the 840, and those juicy tidbits will all be filtered into our review, so don't miss this one!
