MacBook Pros with 7200RPM HDDs getting a touch too noisy?

MacBook Pro hard disk storage really seem to be down on its luck this generation. First was the 3Gbps SATA transfers (now fixed), which honestly didn't affected but a marginal percentage of users upgrading to SSD themselves. Now comes word from a number of irate users on the Apple support forums that claim their HDDs, specifically those spec'd at 7200RPM, are suffering from performance issues and some audible clicking / beeping sounds. The folks at Other World Computing chimed in to say that it might have something to do with the Seagate Momentus 7200.4 G-Force drives, which takes anti-shock precautions that are possibly causing both noise and extra strain. If you're not hearing anything now, we wouldn't suggest you start getting hyper paranoid over the issue -- it's the internet, where things often get blown way out of proportion, in case you haven't noticed. If you're still worried / curious, hit up the read link for the full collection of anecdotes.

Carbon ring storage promises 1,000 times higher memory density


Terrifying news, kids: we're growing seriously close to maxing out the density limits of present magnetic memory technology as it becomes increasingly difficult to shrink the necessary grains used in the process. Thankfully, there's a team of German scientists devoted to doing more than standing around and watching the inevitable happen. Cobalt, the element responsible for keeping your precious data intact, typically requires a 50,000 atom fleet for each grain, but boffins from Dresden have found a way to shrink that to a measly flotilla of 50. Without trampling you with technological details, attaching carbon rings to the cobalt reproduces the requisite hexagonal close packed structure, which leads to reduced space requirements. Should this technique prove viable, we can expect yet another race among hard drive makers as they strive to make each other's most capacious drives look downright diminutive. Hit the read link for all the grisly details.

Digital Rosetta Stone memory could last a thousand years


The race for bigger and better memory continues apace, it seems. It was only a week or two ago that we caught wind of the work that scientists in Berkeley were doing with nanotubes and thousand-year-plus memory lifespans, and now it looks like a group of researchers in Japan have made some headway using an electron-beam direct-writing technique that utilizes semiconductor devices that can keep data intact for a thousand years, so long as humidity is kept at 2% or less. The prototype Digital Rosetta Stone, developed by Keio University, Kyoto University, and Sharp, has a storage capacity of 2.5TB and a max transmission speed of 150Mbps. Of course, there's no telling if or when this will become a reality, so if you want to ensure that your adolescent poetry lasts for the next thousand years, you'd better print out your MySpace blog and have it carved in granite.

Nanometer wars heat up, Toshiba and Intel enter unofficial race

Think the megapixel race is bad? Now we've another to worry about, with both Toshiba and Intel hastily approaching 0.01nm technology in order to make chips faster, more nimble and smaller. According to undisclosed sources at Digitimes, Intel has actually canned production plans for its 45nm Havendale processors, which were originally slated to slip into machines later this year. The cause? It's heading straight to 32nm, reportedly hoping to ship its Clarkdale line in Q1 2010 with entry-level prices ranging from $60 to $190. In related news, Toshiba is joining the likes of IBM, Samsung and Globalfoundries in an effort to dish out chips based on 28nm process technology. Needless to say, the move is being made in an effort to "stay relevant in an area dominated by the likes of Intel Corp and Texas Instruments." Now, if only we could get one of these potent, low-power chips inside of a netbook, we'd be pleased as punch.

Seagate's FreeAgent Go series bumped to 640GB

Seagate's giving its FreeAgent Go drives a fresh new 640GB capacity ceiling, and while it's not the first external to cross that 500GB threshold, it's certainly on the thinner end of the totem pole, physically. Nothing revolutionary here otherwise, it's still the standard USB-connected with up to 480Mbps transfer with multiple color options. Also distinctly the norm? Not a bit of info on pricing or availability, but if Seagate's posting promotional materials on its main site, we suspect it's not too far off.

Samsung debuts first 32GB DDR3 memory module


Samsung has been making promises about a 32GB DDR3 memory module since it rolled out its first 50nm 4Gb DDR3 memory chip way back in January, but it looks like it's now finally delivered. While it won't be headed for regular desktops or laptops just yet, the company does have a new 1.35 volt 32GB module for servers which, in addition to packing that record-breaking capacity, also boasts a 20% better throughput compared to previous 1.5 volt modules and, of course, a lower power consumption to boot. As some math not performed by us will reveal, the module itself is made up of 72 of those 4Gb memory chips, which are lined up in rows of nine quad-die packaged 16Gb DDR3s mounted on each side of the circuit board. No word on pricing just yet, nor is there any word about Samsung's promised desktop and laptop memory, which are apparently still in the works -- in the form of 8GB DIMMs, at least.

Researchers create nanotube memory that can store data for a billion years


Researchers at the Department of Energy's Lawrence Berkeley National Laboratory and UC Berkeley have developed an ultra-dense memory chip that is capable of storing data for up to a billion years (besting silicon chips by roughly... a billion years). Consisting of a crystalline iron nanoparticle shuttle encased within a multiwalled carbon nanotube, the device can be written to and read from using conventional voltages already available in digital electronics today. The research was led by Alex Zettl, who notes that current digital storage methods are capable of storing mass amounts of data, but last just decades, while, say, some books have managed to last nearly a thousand years, though the amount of data they contain is quite small. The new method, called shuttle memory, is based on the iron nanoparticle which can move back and forth within the hollow nanotu. Zettl believes that, while shuttle memory is years away from practical application, it could have a lot of archival applications in the future. There's a video after the break, hit the read link for more tiny details.

Corsair DDR3 memory clocked at 2533MHz, women swoon 'round the world


Corsair -- the swashbucklin' favorite of privateers in need of RAM and SSDs -- has just announced that its Dominator GT DDR3 memory has been overclocked at a pretty astonishing 2533MHz. As you'd expect from a company made of braggarts and rogues, its claiming the world record for itself -- unless, of course, one of you other memory manufacturers feels like taking this bad boy on. Kingston, we're looking at you. Hit that read link for all the salacious details.

Samsung's PRAM chips hit mass production in June

Mark your calendars, memory enthusiasts, for the date you've all been waiting for. Samsung's phase change RAM will go into mass production starting in June. The PRAM chips -- not to be confused with parameter RAM, often what you curse / reset if you've got a Mac on the fritz -- can rewrite data without having to erase what's already on there first. The company's still boasting it's 30x faster and has 10x the lifespan of traditional flash memory. You want to know what gadgets and gizmos will first use these chips? Us too, but we're all gonna have to wait because Sammy's not talking yet.

Neuroscientists in Brooklyn successfully erase memories with drugs

Researchers at SUNY Downstate Medical Center have apparently been tinkering with selectively erasing the memories of rats with a mysterious drug they call ZIP. In the trial, mice who had learned to avoid an electrified area of their cage, once injected with ZIP, appeared to have forgotten about the electrification, and ceased to avoid the area. They have also successfully made the rats forgot about their distaste for a substance that had previously made them sick. Dr. Todd Sacktor, head of the project, believes that the drug may be used in humans one day, and that it may also help enhance memories as well. We don't really have any specific info about the drug itself, or how it works, so until then... we'll just have to keep hoping that the lyrics to Use Your Illusion II fade on their own.

DDR3 shootout pits OCZ, Kingston and Corsair against one another


DDR3 modules aren't exactly new or anything, but given just how low the prices of big time kits have become, we figured it prudent to pass along one of the most thorough shootouts on the subject that we've seen. HotHardware grabbed a few DIMMs from the labs of OCZ Technology, Corsair and Kingston, threw 'em all in a Core i7 rig (not simultaneously, silly!) and benchmarked the lot until they literally fell asleep at the keys. The results? We'd love to tell you which sticks came out atop the pile, but that would just be spoiling the fun for you, now wouldn't it? Give the read link a look if you're ready for the action.

Dell's Mini 10 comes with any amount of RAM you want, so long as it's 1GB

Dell's Mini 10 comes with any amount of RAM you want, so long as it's 1GB
The case of the Mini 10 just gets curiouser and curiouser. The company finally acknowledged the red-lidded QVC stepchild on its site just last week, but before that quietly mentioned an interesting bit of information on its official blog: the 1GB of memory figure that seemed like just a start is actually the end, too. The RAM in the first batch (or possibly batches) of Mini 10 models will be non-upgradable, and while we don't know why a company that built itself on allowing people to customize computers would prevent them from upgrading their netbooks, we are sure this won't be a popular move. Additionally, the first Mini 10s will all be running XP, though Ubuntu will be coming, as well as an optional 720P display and even a TV tuner. That all sounds fantastic, but after waiting through all this is anyone going to wait longer still for a proper-spec'd machine?

Samsung begins production of 50nm GDDR5 memory


It's still a little ways away from actually landing in some graphics cards, but Samsung has announced that it has begun mass production of its new 50nm GDDR5 memory, which promises to support a maximum data transfer speed of 7.0 gigabits per second and boast a maximum bandwidth of 28 gigabytes per second. What's more, according to Samsung, the shift to a 50nm manufacturing process also increases production efficiency by a full 100 percent, and allows the memory to operate at 1.35 volts, which is a 20 percent reduction compared to current GDDR4 memory. From the looks of it, however, manufacturers will have to make do with a 32Megabit x 32 configuration (also configurable as a 64Mb x 16 device) initially, although Samsung says it plans to expand the 50nm process throughout its graphics memory line-up by the end of the year.

Toshiba makes progress on FeRAM, still no tangible product in sight

Phew. For a moment year or so there we reckoned that amazing FeRAM discovery had been pushed aside and forgotten entirely. Thankfully, Toshiba has picked up the ball and refined the original chainFeRAM architecture by creating a new architecture that prevents cell signal degradation -- which, as you may or may not know, is the usual tradeoff from chip scaling. In essence, this has allowed the company to design the world's highest bandwidth, highest density (128-megabit) non-volatile RAM. Unfortunately, this amazing device -- which should realize read / write speeds of 1.6 gigabytes a second and combine the fast operating characteristics of DRAM with flash memory's ability to retain data while powered off -- is still in prototype form, which probably means we're months (if not years) away from actually seeing a tangible end product hit store shelves.

Rambus introduces 4.3Gbps mobile memory

It's not all just lawsuits and overinflated posturing for Rambus -- the prickly memory firm will later today demo what its calling the Mobile Memory Initiative, a 4.3Gbps phone-oriented variant of the XDR RAM used in the PS3 that requires just 100mV of power. That means companies can either build super-powerful phones that take advantage of a complete MMI system's estimated 17GBps throughput, or build cheaper devices that offer performance equivalent to today's memory with fewer MMI parts. Rambus won't say who it's working with to bring out MMI, but we're going to have to wait a bit before we all score cheap HD videophones -- the first products aren't scheduled to hit until early 2010.
