Western Digital 2TB Caviar Green review roundup
Now that the proverbial cat is out of the bag on Western Digital's 2TB Caviar Green HDD, hardware fanatics have had a chance to take the 3.5-inch drive for a spin. While its performance leaves something to be desired -- transferring files took longer than the 1TB Caviar Black or 1.5TB Seagate Barracuda -- instead we've got low heat and noise. Of course, the biggest boon is a ginormous storage capacity for just three Benjamins, the same price as some 128GB SSDs. Solid state be damned, rotating disks aren't going away anytime soon.

Rogue Android app said to be wiping G1 user data
PSA: you should probably cancel that MemoryUp Personal download from the Android Market. Like, right now. According to legions of T-Mobile G1 users who gave the program a go, it's pretty much an abject disaster. The app bills itself as being "a handy memory optimizer tool that will keep your Android smartphone running faster and efficiently," but more than a few users have reported that it actually wipes oodles of precious data instead. Reports ranging from cleared SD cards to completely erased contact lists have appeared time and time again, with many straight-up calling it a scam. We're not looking for Apple-like safeguards on the store or anything, but maybe a test or two before letting this thing fly would've been nice, no?
New MacBooks said to have issues with maxed out RAM, faulty NVIDIA GPU
While most of the complaints about the new MacBooks and MacBook Pros have focused on things like the screen or the absence of a certain much-loved port, it appears that another problem has been bugging some folks that went ahead and maxed out the RAM on their shiny new laptop. Apparently, loading 4GB of RAM (either from Apple or a third party) has caused at least a few MacBooks and MacBook Pros to freeze up randomly which, for the time being at least, can only be remedied by dialing things back to 2GB or 3GB of RAM (something tested by jkOnTheRun). While Apple isn't saying anything publicly about this just yet, one member of the Apple support forum claims to have heard from an Apple engineer who says that Apple is, in fact, aware of the problem and that a software update is on the way to fix it, possibly within a few days.In related MacBook news, The Inquirer is now reporting that the new MacBook Pro's NVIDIA 9600M GPU suffers from the same so-called "bad bump" problem that has plagued previous generation MacBook Pros (and provided plenty of fodder for The Inq) which can, in some cases, lead to blank screens and other video errors. It's not clear, however, if the problem affects all MacBook Pros or just a bad batch, although there does appear to be a somewhat sizable number of complaints cropping up.Read - jkOnTheRun, "MacBook fussy memory situation- maybe 4 GBs is too much"Read - the Inquirer, "Inquirer confirms Apple Macbook Pros have Nvidia bad bump material"[Via Electronista]
New MacBooks and MBPs can handle up to 6GB of RAM
Is it just me or is it pretty mindblowing what Moore's Law is doing to our computers these days? I remember when 64mb of RAM was great, and even a few years ago, I wondered why anyone would ever use 1GB of RAM (I've got 2GB in my gaming PC, and I still almost think it's too much). But apparently TidBITS has been doing some testing, and they've discovered that not only can the new MacBooks hold 4GB of RAM as Apple recommends for a limit, but stuffing a whopping 6GB in there is possible and doable. There are two DDR3 slots in the new MacBooks and MacBook Pros, and they come with either 1GB or 2GB in each DIMM slot.TidBITS says you can switch out one of those 2GB DIMMs for a 4GB, and voilà, as long as they're the same speed and type, apparently almost everything is hunky-dory. TidBITS says there are two drawbacks: one, that dual-channel architecture requires identical DIMMs, so that's out if you're running a 4GB and 2GB configuration. Plus, it'll cost you an arm and a leg, especially if your leg is priced at around $600, which is what a 4GB stick runs. Even the DDR2 is pricey at that level (then again, if you don't like memory prices, just wait about five minutes, because that's basically how often they change).And for some reason, there's an issue with running two 4GB sticks in there (for a total of 8GB), but TidBITS surmises that may be fixed by the time Snow Leopard rolls around. Personally, I'd love to see a program that needs 6GB of RAM -- maybe a high end 3D modeler or a financial simulator of some kind. But it's good to know that if you really need that much memory (and have the cash to spend on it), there you go.
Thirteen WoW windows in 36 seconds with an SSD
This is cool, but pretty technical -- if you don't know your USB from your Firewire, it might not make much sense. But the guys at TGDaily were apparently playing around with a Fusion-io solid state hard drive at E for All last weekend, and to show off the drive, they loaded up thirteen World of Warcraft windows in just 36 seconds.Normal hard drives, like the one in your computer (unless you've already shelled out a ton of cash for an SSD) have discs in them that spin, and they take time to find the information stored on them -- that's why, when you double click your WoW icon, it takes a few seconds (up to a few minutes if you've got a slower computer) for your WoW window to load up. But a "solid state" hard drive doesn't have discs or moving parts -- it's essentially one big block of memory -- so it's much, much faster in terms of retriving information. And what's going on in the video on their website is that they're pulling so much information from the hard drive that WoW is installed on that it's taking only seconds to load up thirteen windows' worth of WoW.Of course, how fast all of those windows actually run depends on a lot of other things in the computer -- you'd need a lot more than just an SSD to have the video power to run 13 separate 3D windows at the same time (though TGDaily says they weren't breaking the bank at 5 instances running, they just didn't have any more accounts), not to mention the bandwidth that would come from 13 different connections. But just the startup is interesting enough -- eventually these SSD drives will become cheap enough to be used all over the place, and information will be almost instantly accessible from wherever it's stored on your PC.
16GB Hynix DDR3 RAM modules demonstrated at IDF
Remember that MetaRAM technology we figured was nothing more than a sophisticated joke back in February? Intel, one of the noteworthy backers, has proven that said tech actually is one rung above snake-oil at its own Developers Conference in San Francisco. Hynix-made DDR3 DIMMs packing 16GB of memory were reportedly created via the MetaRAM method (and subsequently shown off), and just in case you're not wowed by such wizardry, the demo system included no fewer than ten of these modules. Just in case that sort of flew over your head, the machine they were in possessed 160GB of RAM. Unfortunately, we've a feeling these are quite aways out from hitting the consumer market.
Samsung makes mobile memory go zoom with new software
If there's one thing smartphone can never be, it's too fast. Yeah, granted, mobile processors have been intentionally throttled for years in the interest of keeping battery times reasonable -- so we're always delighted to hear when someone's doing something to boost speeds in different, creative ways. That's where flash memory giant Samsung comes into play, rolling out new file systems and drivers for its OneNAND, Flex-OneNAND, and moviNAND storage solutions (none of which are pictured to the right) that it claims will slap a turbocharger on boot and access times. The new software is available for basically every major mobile operating system, and Sammy even claims that it'll decrease engineering times, so it looks like it's a win all the way around.
SanDisk and Toshiba join efforts to build "3D" flash
We first heard about Toshiba's plan to increase NAND flash capacities by building "3D" memory chips with "pillars" of stacked cells in January of 2007, but it looks like the effort is getting revived -- Tosh and SanDisk have entered into an agreement to jointly develop and cross-license 3D memory tech. SanDisk was once rumored to be developing write-once 3D flash chips, so both companies have experience building the stuff, but it sounds like it'll take another three or four years for the partnership to produce actual products, as high-yield production is still difficult.
Intel and Micron produce first sub-40nm NAND device
Just a few months back, we all gave SanDisk a round of golf claps for moving towards 43-nanometer NAND production. Fast forward to today, and that "feat" doesn't look so mighty anymore. Intel and Micron have just announced the industry's first sub-40nm NAND flash memory device, the 34nm 32 gigabit multi-level cell chip. The process technology was collaboratively developed by the two firms' joint venture, IM Flash Technologies (IMFT)," and there's nary a hint of shame when they trumpet that this is the "smallest NAND process geometry on the market." Sample shipments are expected to leave the dock in June, while mass production should get going sometime in the second half of this year. Somehow, we get the impression this won't stay on top for long.
Wii Warm Up: New storage theories
Now that Iwata has said that folks at Nintendo might be considering doing something about the storage crisis, it's time to get our speculation on about what will happen. Will we hear an announcement at E3? Perhaps before, or -- gasp -- after? We would hate to wait! And what'll it be? A new model with a built-in hard drive? Considering the continuing difficulty some people have with simply laying hands on a Wii, that seems unlikely, but multiple SKUs have worked for the other systems. Still, that sort of solution seems far, far less likely than an upgrade allowing larger SD cards or additional plug-in flash memory. Do you think we'll see a solution by the end of the year, and do you care to guess just what it might be?
HP creates radical 'memristor' technology, brains explode
"Memristors" are one of several memory technologies that have been theorized and promised in the coming years. HP has made a real memristor, however, and the way solid state memory is created and stored could have just changed forever. First theorized in 1971, memristors are basic circuits like resistors, capacitors, and inductors. These circuits are able to store data by allowing their levels of electrical resistance to fluctuate between high and low, or 0 and 1 to a computer. Like flash memory, they retain that data without power -- except they do it all on one circuit and at the speed of D-RAM. In the end, we could be looking at a whole new kind of storage, as long as someone can figure out how to get these things onto integrated circuits. Nerds hats off, return to your fanboyism -- now.
IBM's racetrack memory dashing towards commercialization
So, how do you go about impressing the world after busting out a few systems based around the "fastest chip on Earth?" By getting us all worked up for a little thing called racetrack memory, that's how. Far from being the first memory technology that runs laps around the DIMMs we're relying on today, IBM researchers are suggesting that this iteration could enable users to store substantially more data at a lower cost and be available in around a decade. Put simply, the gurus working the project have discovered a way to overcome the prohibitively expensive process of manipulating domain walls in magnetic storage, essentially making a long-standing approach entirely more viable. If you're totally in nerd heaven right now, we assure you, checking out the explanatory video waiting after the jump is a must-do.[Via BBC]
Away: Shuffle Memory
The official website for Mistwalker's Away: Shuffle Dungeon is up, with something to help pass the time while waiting for the dungeon crawler's eventual release: a Flash minigame based on Concentration/Memory (click on the circle with the word "open" on it). Away: Shuffle Minigame (that's the official title!) comprises three levels of Memory played on a 6 x 3 grid, with the goal of flipping matching pairs of cards to reveal portraits of Away's characters.For the first two levels, it's straightforward enough: you have 60 (and then 50) seconds to find all nine pairs, just like any other Memory game. In the third level, all the cards are blank but three: one pair to match, and one card that resets the locations of those two cards. Oh, and the rows of cards are constantly moving around. At the end, you're awarded with a desktop wallpaper. Have fun! Or just download the wallpaper here (1024x768, 1280x1024).
Hynix ships fastest one-gigabit LPDDR2 chip for mobile devices
Though not quite as impressive as the idea of toppling Intel and AMD within the next ten years, Hynix Semiconductor still has a decent reason to brag today. The South Korean chip producer has announced that it has just started mailing out the "fastest data transferring advanced dynamic random access memory (DRAM) chip for mobile devices." Said chip is the one-gigabit LPDDR2 (low-power double-data-rate 2), which was crafted using 66-nanometer technology and features an 800-megabits per second operating speed at 1.2-volts. No word on exactly what devices will see the super-speedy chip packed within, but a company spokesperson did note that it plans on ramping up production during Q4 to meet "growing demand for flat-panel television sets and high-end handheld devices."[Via Physorg]
Evernote: universal human memory extension
Evernote has plans for your brain. More specifically, a vision for the the augmentation of your memory. Phil Libin, CEO of Evernote and a recent Mac convert (who's been enthusiastically replacing his relatives' PCs with Macs to cut down on tech support calls) filled us in on Evernote's big plans. Originally, Evernote was a Windows desktop application for taking notes, and it was (and is) top-ranked in its class. Then they decided that a broader array of input options and more accessibility could take Evernote light years beyond the initial plans. This included creating a Mac desktop client and a web application to interface everything. It can take your text notes, web clippings, pictures and more, organizing them with a tagging system and attribute filter. The ultimate goal of Evernote is to be, as Phil puts it, a "universal human memory extension." The Mac desktop client is being developed from the ground up, not ported from the Windows client. This makes for a true Mac experience and a beautiful interface. Feature parity will eventually be maintained (Windows users currently have a slightly different feature set), but the two clients are being developed separately. Read on after the jump to find out what makes Evernote different from your current system for tracking all the information in your life (and find out how you can get in on it!).
MetaRAM aims to bump RAM capacity by 4x overnight
We're not sure what whacky voodoo snakeoil these MetaRAM people are peddling, but the company's got some high profile behind it (like Intel, for one), is being led by former AMD CTO Fred Weber, has appears to have some potentially revolutionary RAM quadrupling technology. Claiming to have leapfrogged current RAM technology by 2-4 years, MetaRAM uses a specialized "MetaSDRAM" chipset that effectively bonds and addresses four cheap 1Gb DRAM chips as one, tricking any machine's memory controller into using it as a 4x capacity DIMM. Since a 1Gb chip is apparently far less expensive than a 2Gb chip, MetaRAM devices can multiply capacity at prices far lower than their competition; the company claims it'll be shipping in machines in the first quarter of this year, and Hynix has already announced their own 2-rank 8GB DDR2 RDIMMs for the second half.
iFreeMem 2.0: when you just don't feel like rebooting
As good as OS X memory management may be, if you run your system for long periods of time without shutting down you'll likely see an increasing number of spinning beach balls as your uptime counter ticks away. When applications quit – especially big, memory-hungry applications – they often leave your RAM fragmented and unavailable to subsequently launched apps. The solution is generally a reboot, but if you're looking for something a little friendlier and less time-consuming, iFreeMem is a superb solution. The utility was just updated to version 2.0 with full Leopard support. I'm a long-time user of iFreeMem. On my MacBook Pro with 3 GB of RAM, it can generally clear up about 800 MB (sometimes more) after I quit a long session in apps like Photoshop and Motion. And it's rescued me on numerous occasions where I've found myself with three or four MB free and everything starts slowing to a crawl. I just loaded version 2 and it's faster and more efficient than ever. Good stuff. The author has signed up with Trial-Pay, which I can't say improves the image of the app or increases my respect for it, but it does provide one option to get a $19 application for free. In light of the overall positive nature of this post, I won't delve into my opinions on Trial-Pay and its ilk. Suffice to say that I'm a happy customer of iFreeMem who paid full price and have never regretted it. Oh, and the 2.0 upgrade is free for users of previous versions, you just have to re-enter your registration code. You saved it, right? Get a feel for whether or not iFreeMem would save some reboots for you with a 15-day, fully functioning trial.
A physical limit on bag space
Just the other day, Adam suggested that more bag space was always a good thing, but now Drysc tells us that's not exactly true-- even though 20-slotters are more common than ever, Blizzard has no plans to let us replace the normal 16-slot backpack anytime soon. And the reason he cites is interesting: it has nothing to do necessarily with ingame limits, but more to do with out-of-game limits. WoW has 10 million players, and if each one of those players has easily 10 alts average and each alt has a bunch of 20-slot bags and even more items in the bank, then pretty soon you're starting to talk real amounts of physical computer memory.We don't know what that limit is (and of course it depends on how Blizzard stores their information), but Drysc tells us that it's there. And that also gives you a little hint into just how huge their operation is-- nobody else has even come close to dealing with the problem of handling inventory and stats information for ten million players and countless numbers of characters. But Drysc says Blizzard is working on it as always-- despite the technical headaches, we may see bigger backpacks soon.
Wii Warm Up: Channel surfin'
We were intrigued by not only a comment on the VC Monday Madness video wrap-up this week, but also the weekly chore (for this blogger, at least) of rearranging Channels and moving content to and from the SD card. The Wii may have some internal memory, but it's not enough for a console that has to download every Virtual Console game.So, we thought about moving Channels around, which we've affectionately dubbed "Channel surfin'" for ease of conversation. How often do you need to drag stuff around on your Wii? Never? Not the type to load your Wii with content that isn't on a retail disc?
Nanochip technology offers up cheap, 100GB flash memory alternative
It's like we can't make it through the week these days without word of some outlandish memory technology solving all worldly ills; but it's not that we're complaining. This week's featured tech comes from Nanochip, and promises gains in storage quantity and cost per chip over flash memory. The first prototypes will store 100GB, and will be shipped to device makers next year for evaluation. Nanochip technology stores data on a thin-film material, and accesses it using microscopic cantilevers. Each bit will be 15 nanometers wide at first, with theoretical sizes as small as a couple nanometers. Speeds will be near that of flash, and the data could last longer. There are still some obstacles to accessing the data efficiently, but luckily Nanochip just scored $14 million in funding to complete its pursuit. IBM has been pursuing a similar tech since the late 90's.
