samsung-ssd-awesomeness.jpgWhat happens when you string together 24 256GB Samsung MLC SSDs - you get 6TB of storage and 2GB/sec throughput. Sweet mother of —!

Discovered the news on Lucas Mearian’s Computer World blog who writes:

When you’ve got millions of dollars at your disposal, and access to some of the industry’s best hardware engineers, what do you do? Well, if you’re Samsung you make a YouTube video showing the speed, capacity and reliability you can get by stringing together 24 solid state disk drives behind a RAID controller to create “the world’s most powerful consumer computer”. The result: 6TB of storage and 2GB/sec throughput that is able to load 53 programs 18 seconds. Whoa.

The video below shows the 24 SSDs setup along with some interesting benchmarks. For instance, in the video they rip a 700MB DVD in 0.8s, open all of Microsoft Office apps in 0.5s, and launch 53 programs in 18.09s! At $500 a pop per SSD, it’ll cost you $12,000 for ludicrously fast hard drive speeds! Of course, I remember writing about Samsung’s Super Fast SATA hard drive in 2004, which featured 3Gb/s speed using traditional HDD technology, which is cheaper than SSDs. Of course, it’s 3Gb/s (3 Gigabits per second) not 3GB/s (3 Gigabytes per second), so you’d have to divide that by 8 bits per byte or 0.375 GB/s or 375MB/s. That’s odd - that’s faster than the 220MB/s random access speed of each individual SSD (aggregate is 24 x 220MB/s). I thought SSDs were generally faster than hard drives? Something must be off in my math. Actually, just read that the 3GB/s is the speed of the I/O channel. The read speed is 1.5GB/s or 0.156 GB/s, which is 156MB/s . Now that sounds more accurate!

And then of course, there’s perpendicular hard drive technology, which is a new way of “squeezing” more bits onto a hard drive by changing the orientation of the way the bits are recorded. Normally magnetic bits are written parallel to the drive’s surface, but not with perpendicularity - its 90 degrees perpendicular to the normal parallel orientation. Because the bits are recorded upright and “into” the surface of the drive platter, you can squeeze a lot more bits together without the bits polarity causing the bits to flip their magnetic orientation. Check out my blog post where a classic School House Rock video makes an appearance along with a hilarious Hitachi video on perpendicular HDD technology.

Anyway, here’s the 24 SSD RAID video:

SanDisk G3 SSD Memory Blows Away Hard Drives’ Performance

by VoIP & Gadgets Blog in January 8th, 2009   
Topics: Computer Hardware, ExtremeFFSTM, Gadgets, RAID, SSD, Sandisk, TMCnet, drives, memory, performance, solid-state drives, using     

sandisk-ssd-g3.jpgSanDisk today unveiled its third-generation family of solid-state drives (SSDs). Using multi-level cell (MLC) NAND flash memory technology, SanDisk’s G3 Series of SSD memory has incredible performance benchmarks. The G3 SSDs are more than five times faster than the fastest 7,200 RPM hard disk drives and more than twice as fast as SSDs shipping in 2008, clocking in at 40,000 RPM and anticipated sequential performance of 200MB/s read and 140MB/s write. Even the fastest hard drives I’ve seen to date, which I have installed on serveral servers at TMC, currently max out at 15,000 RPM.

They were designed as drop-in replacements for hard-disk drives (HDDs) in notebook PCs, the initial members in the SanDisk G3 family are SSD C25-G3 and SSD C18-G3 in the standard 2.5″ and 1.8″ form factors, respectively, each available with a SATA-II interface. Available in capacities of 60, 120 and 240GB*, the unit MSRPs are $149, $249 and $499, respectively. The G3 SSDs provide a Long-term Data Endurance (LDE) of 160 terabytes written (TBW) for the 240GB version, sufficient for over 100 years of typical user usage. Using such fast memory instead of a hard drive in a netbook, laptop, or even PC desktop should make these computers nearly instantly boot. Sweet!

Three key features developed by SanDisk enable this new design: a new SSD algorithm called ExtremeFFSTM allows random write performance to potentially improve by as much as 100 times over conventional algorithms; reliable 43nm multi-level cell (MLC) all bit-line (ABL) NAND flash; and SanDisk’s new SSD controller, which ties together the NAND and the algorithm.

The SanDisk G3 SSDs will be available in mid 2009, in a 2.5″ PATA configuration. Now we just need SSD RAID5 or SSD RAID10 using multiple SSD cards and then we can finally say goodbye to current expensive RAID5/10 server configurations that require expensive hard drives and RAID controllers! Wow, servers would also be blazingly fast using multiple SSD cards working in parallel in a RAID configuration.

Toshiba 512GB Solid State Drive

Toshiba announced that it will showcase a 512GB solid-state drive (SSD) at the Consumer Electronics Show (CES) next month, with shipments of this large SSD in the second quarter of 2009. These NAND-flash-based solid state drives (SSD) will be the industry’s first 2.5-inch 512-gigabyte SSD and features fast read/write times and reliable performance for laptops/notebooks, and other equipment.

In addition to the 2.5-inch, 512GB drive, the 43nm NAND SSD family also includes capacities of 64GB, 128GB, and 256GB, offered in 1.8-inch or 2.5-inch drive enclosures or as SSD Flash Modules. The drives feature a maximum sequential read speed of 240MB per second (MBps) and maximum sequential write speed of 200MBps. This should definitely result in faster boot and application loading times. The drives also offer AES data encryption to prevent unauthorized data access.

512GB soon… next stop 1TB (1 terabyte)!

Scientists develop software that can ‘Draw’ your Dreams

woman-sleeping-pillow.jpgScientists have developed software that can ‘draw’ your dreams by reading your mind. Your dreams have now been unlocked with the invention of technology capable of illustrating images taken directly from human brains during sleep.

According to Telgraph.co.uk:

A team of Japanese scientists have created a device that enables the processing and imaging of thoughts and dreams as experienced in the brain to appear on a computer screen.

While researchers have so far only created technology that can reproduce simple images from the brain, the discovery paves the way for the ability to unlock people’s dreams and other brain processes.

We just took one step closer to telepathic communications, which would make this at least one half of this VoIP & Gadgets blog moot. After all, who needs Voice over IP communications when you can just “think” your thoughts and people can hear/see them? May as well ditch the iPhone as well. Who needs a mobile phone when you can communicate telepathically?

As a matter of fact, once they perfect this thing, maybe you can loop back the playback into your brain’s auditory and visual cortex centers so you can go back and watch your favorite movie in the theater or hear your favorite concert. Who needs an iPod mp3 gadget when you can simply playback past memories? Ok, the device is passive and only records what your brain is thinking - it cannot send input to the brain to tell it to playback a memory.

We’re getting close though my friends.

Free Those Trapped Cell Phone Photos!

by VoIP & Gadgets Blog in August 7th, 2008   
Topics: CNET, Digital Cameras, bluetooth, camera phone, memory, memory card, micro sd, mini sd, phone, phones, pictures     

samsung 32876795-2-200-0.gifGetting your great candid pictures off your camera phone is no easy matter — it should be so simple!

CNET gives us a couple of ways to do it. One of them has got to work!

The least labor-intensive way to rescue your pictures from being trapped on your phone is to send them to an e-mail address in a multimedia message. But as you know, this costs money, so you’ll be pleased to hear there are alternatives.

If your phone accepts a memory card, you can save your pictures to the card, then use the card to transfer the images. Most cell phones use smaller memory cards in a Micro SD or Mini SD card format, so if you don’t have an adapter, the cards won’t fit in most readers.

If you don’t have a memory card slot, you can use Bluetooth or an infrared port to send shots to another capable device. But be wary, because some carriers block some Bluetooth transfers on its phones.

Still another method is to use a USB cable that connects your cell phone with your computer. Not all phones have USB capability, so check to see if yours does. Also, USB transfers on some phones require software from the carrier or the manufacturer.

If your phone doesn’t come with any of the features, don’t despair, as you’re not out of luck. A final method is to invest in cell phone-syncing software. Although these products require an initial investment, it’s not an ongoing one, and you’ll be able to not only transfer photos but also sync your calendar, your contacts list, and your messages.
