Samsung creates F2FS file system for NAND flash storage, submits it to the Linux kernel
Has the lack of NAND flash storage-optimized file systems been bugging you? Then you've got something in common with Samsung, which has developed F2FS (or "Flash-Friendly File-System") for the memory of choice for mobile devices and its specific "internal geometry." It's based on a log-structured method, but tackles problems associated with older file systems intended mainly for retro, spinning-disk storage. The company isn't keeping its hard work behind lock-and-patent either -- it's gone open-source and submitted the file system to the Linux kernel, meaning you could see it implemented in Android hardware of the future. It's nice to see Sammy contributing code for the greater good, and if you've got the skills to understand it, a low-down of F2FS is available at the source below.
Samsung starts mass-producing 4x faster mobile flash memory, kickstarts our phones and tablets
Samsung isn't content to leave fast NAND flash memory to traditional solid-state drives. Its Pro Class 1500 promises a big jolt to the performance of frequently pokey smartphone and tablet storage. By how much? That name is a clue -- it reaches 1,500 IOPS (inputs/outputs per second) when writing data, which along with 3,500 IOPS data reads is about four times faster than any previous embedded flash chip Samsung has tested. In the real world, that leads to as much as 140MB/s when reading data and 50MB/s for writes. The speed comes after Samsung has thrown virtually every trick in the book at its new chips, including a dense 20-nanometer manufacturing process, quick toggle DDR 2.0 memory with its own controller and a new JEDEC memory standard with 200MB/s of bandwidth to spare. Samsung hasn't named customers for the 16GB, 32GB and 64GB parts that are rolling out of the factories, although we'd do well to remember that a flourishing phone business doesn't guarantee that the only major customer is Samsung itself: even in the face of legal challenges, Samsung still has at least one noteworthy client that tends to snap up much of its flash supply.
Researchers develop silicon ReRAM chip, send warning shot to Flash memory
Does the word ReRAM ring a bell? No? Well, the key point is that it's much faster than NAND memory, and it's making its way into chips from Elpida, Sharp and Panasonic. Further proof that ReRAM is on the up and up? Researchers at University College London have used this technology to make a chip that operates at 100 times the speed of standard Flash memory. The device is composed completely of silicon oxide, which improves the chip's resistance, and it doesn't require a vacuum to work (which makes it cheaper to produce). But this new chip is more than just a faster alternative to Flash; its ability to move between different states of conductivity means it can be configured as a memristor, or a device that handles both data-processing and storage tasks. In the long term, researchers hope this technology can pave the way for silicon oxide CPUs -- and UCL is already using this design to help develop transparent memory chips for mobile devices.

Toshiba sings NAND Flash's praises, thinks you should too
Have you taken a moment today to stop and thank NAND Flash for existing? No? Well, Toshiba would like to say tsk, tsk. Today the company launched a full-scale campaign to promote this storage technology -- and by full-scale we mean a dedicated "25 Years of NAND Flash" website, a "NAND Flash Deprivation Experiment" video series, new Facebook and Twitter accounts and a Toshiba Excite 10 giveaway. We must have missed the memo that NAND was dangerously underappreciated, because we're still trying to figure out why it needs a marketing campaign of its own. Toshiba has a slew of laptop refreshes and the Excite 7.7 and 13 tablets just around the corner -- and that interim period between announcement and launch date can be killer -- but somehow talking up NAND Flash doesn't seem the right course of action. Take a look at the campaign's first video below the break and decide for yourself.
iSuppli: Apple iCloud could affect NAND Flash market
Apple's upcoming iCloud service could have a negative effect on the NAND Flash market says IHS iSuppli. The market research firm suggests a change from phone and computer-based storage to online storage could lessen demand for flash memory in the future. Of course, iCloud in its current from is a sync service, but this could easily change to a streaming and storage service in the future. This iCloud effect won't be felt immediately. Apple is expected to scoop up 30% of the available supply of NAND flash memory in 2011 and should keep its position as the world's largest buyer of NAND flash memory for the next several years. As consumers gradually move their digital libraries online, the demand for on-device storage could decrease by as much as 100 GB per user. This drop could have a serious impact on NAND flash suppliers like Samsung or Toshiba. [Via Digitimes]
New MacBook Airs may include high-speed 400MBps flash memory
The next generation MacBook Air may get a flash memory boost according to a report from Macotakara. The new NAND flash memory could replace the Blade X-Gale SSDs in the current generation MacBook Air models. This Toggle DDR 2.0 technology boasts of 400 MBps transfer rates and a 19-nm process size. As a result, read times could reach 261 MBps and write times could be bumped up to 209 MBps. [Those performance numbers refer to the current generation of MBA solid state disks, not the rumored next generation. We apologize for the error. –Ed.] These small memory chips may be soldered on the MacBook Air's base circuitry. The new and improved MacBook Air models are expected to arrive soon after the debut of Mac OS X Lion. A Gold Master version of Lion was seeded to developers last week and should be publicly available in the upcoming weeks. [Via AppleInsider]
Buffalo's 256GB SSD comes with 6GBps SATA interface, silly price tag
The SSD market is about to get a little more crowded, now that Buffalo has unveiled a new, 256GB fatty. The company's SSD-N256S/MC400 has a SATA 6Gbps interface, supports multi-level cell NAND Flash memory and boasts read and write speeds of up to 405 MB/s and 223 MB/s, respectively. If you're interested in grabbing one, you'll have to shell out a cool ¥72,200 ($882). Or, you could get an even faster SSD for less money. The choice is yours.
Apple said to be in talks with Samsung to buy $7.8 billion worth of components
It's not clear if it's related to that mysterious $3.9 billion "strategic investment" or not, but it looks like Apple could be about to throw some serious cash in Samsung's direction. According to a report published in the Korea Economic Daily, Apple is expected to purchase some $7.8 billion worth of components from Samsung this year, including displays, applications processors, and NAND flash chips -- all intended for use in iPhones and iPads. As the paper notes, Apple would become Samsung's single biggest customer if the deal goes through, although the two obviously aren't strangers to massive deals -- Apple has already famously run Samsung's flash memory supplies dry a few times.
Apple to become Samsung's biggest customer
A report from the Wall Street Journal suggests Apple is about to become Samsung's biggest customer in a deal estimated to be worth US$7.8 billion. As part of its purchase, Apple will be securing LCD displays, NAND flash memory and mobile chipsets from the Korean manufacturer. Each of these components will be used to build Apple's popular iPad and iPhone. Samsung is not the only parts supplier to receive a big check from Apple. An earlier rumor from iSuppli suggests Apple has invested $3.9 billion in pre-payments to LG display, Sharp and Toshiba Mobile display for LCD technology related to its iOS devices. Instead of direct unit supplies, some of this latter investment may be used to help build out factories and increase production of LCDs for upcoming products. In the past, securing an ample supply of NAND Flash memory was a problem for Apple and the industry at large. During the early boom of the iPhone, NAND flash memory supply was seriously constrained due to the demand of the iPhone. Both Samsung and Hynix, the #1 and #3 memory manufacturers in 2009, struggled to meet Apple's growing orders. At one point, Samsung was thought to have set aside its entire supply of NAND chips for the Cupertino company.
Hitachi-LG unveils 2nd generation hybrid optical drive with flash-based storage to boot
The Hitachi-LG Data Storage joint venture has itself fostered yet another mixed product, combining both an optical disk drive and flash storage into a single form factor. The 2nd generation of its Hybrid Drive uses Micron's 25nm NAND flash memory in 16GB, 32GB, 64GB capacities (with those figures to rise in later iterations, naturally) and can be united with either DVD or Blu-ray players -- perfect for laptops and other portable devices with just one drive to spare. (The one stretched out on display, pictured above, was a 12.7mm slim DVD-RW tray type). Hitachi housed samples of the drive at its CEATEC booth and even showed off a few example products (first generation drive, too). Care to see what could be under the hood of a future purchase?

Keio University and Toshiba ready tiny 1TB SSDs for 2012
Japan's Keio University claims to have developed, in conjunction with Toshiba, the technology to shrink the size of SSDs by a spectacular 90 percent while also cutting energy consumption by 70 percent. If that's not enough mind-boggling numbers for you, the final product of this partnership is expected to yield 1TB drives with 2Gbps throughput. The details of this are still somewhat unclear, but we're told researchers stacked 128 NAND flash chips atop one another, with the breakthrough being in the way they communicate -- using short-range magnetic signals --- which results in less wiring complexity and reduced production costs. We'll take some convincing to believe they can really put these to practical use by 2012 as promised, but if they do make it to any sort of commercial launch, you can bet we'll be queuing up through the night to get one. Note: Nikkei source link requires a paid subscription to access.
Toshiba bolsters 32nm mSATA SSD lineup, your future netbook nods approvingly
We like to think of 'em as the SSDs for the little guys, and we couldn't be happier to hear that they're getting bigger and bigger in terms of capacity. Toshiba introduced the first solid state drives to use the mini-SATA interface back in September of '09, and while those 32nm units were made available in 30GB and 62GB sizes, the pack rats weren't satisfied. Now, the company has introduced a 128GB flavor with an mSATA interface, offering up a maximum sequential read speed of 180MB/s and a maximum sequential write speed of 70MB/s. The 128GB modules are said be one-seventh the volume and one-eighth the weight of 2.5-inch SSDs, and in case that's not enough, the third-generation HG SSDs will bring nearly twice the aforesaid speed and will ship in capacities of 64GB, 128GB, 256GB and 512GB. Hit the source link for all the dirt... except for the pricing, naturally.
Super Talent's 2TB RAIDDrive shipping next month to the rich and silly
Remember that 2TB PCIe RAIDDrive we peeked earlier this year? Yeah, that was no April Fool's joke. Super Talent's answer to OCZ Technology's Z-Drive is on track to ship next month, shortly after it makes a quick stop by IDF next week. The device slots into one's PCIe bus and utilizes a RAID architecture specifically tailored to work with NAND flash memory. In fact, the outfit has actually boosted the transfer speeds from the 1.3GBps estimate to a 1.4GBps promise. The aluminum enclosure houses four discrete SATA SSDs, with the RAIDDrive GS being the model that tops out at 2TB. For those able to deal with "just" 1TB, there's the RAIDDrive ES and RAIDDrive WS, both of which are detailed further in the read link. No exact pricing has been nailed down yet for the flagship unit, but considering that the 1TB RAIDDrive GS is pegged at $4,999 for OEMs, we'll let your imagination do the rest.
Japan's AIST boasts of longer-life NAND flash memory
As we've seen, Japan's National Institute of Advanced Industrial Science and Technology (otherwise known as AIST) is a pretty prolific place and it, along with its cohorts at the University of Tokyo, are now boasting about a breakthrough in NAND flash memory that could result in far longer lifespans. The key to that, it seems, is the use of ferroelectric gate field-effect transistors (or FeFETs, pictured above) as memory cells, which apparently not only "dramatically improves" the performance of NAND flash memory, but allows it to be programmed and erased more than 100 million times. What's more, the FeFET-based memory apparently also requires less power than traditional NAND flash memory, with it able to operate at a programming voltage of less than 6V, as opposed to the 20V of current memory. Of course, there's no indication as to when any of this will find its way into consumer products, with AIST only saying that plans to design and develop the "Fe-NAND" flash memory array circuits and verify their operations in cooperation with the University of Tokyo.[Via Slashdot]
