This is fast turning out to be world storage week, or so it seems. A day after Seagate upped the hard drive capacity ante with its ultra-capacious 4TB FreeAgent GoFlex Desk external hard drive, Dell has begun offering the Precision M6600 and M4600 mobile workstations it launched back in May with the option of 512GB SATA3 Mobility SSDs, “giving users lightning quick 500MB/s read and 300MB/s write times.” What’s more, those interested in the M6600 now have the option of configuring the machine with more than 1TB of SATA III solid-state storage.
Sandisk on Tuesday introduced two new SSD models for ultra-thin notebooks and tablets at the ongoing Computex trade fair in Taipei. According to the company, both the u100 (for ultra-thin notebooks) and the i100 (for tablets) use the SATA III interface and boast “a low-power architecture that reduces power consumption to as low as 10mW.” Hit the jump for more.
Not one, but TWO Intel roadmaps recently fell off a truck and somehow managed to land on the Web, giving curious tech junkies a peek into what the Santa Clara chip maker has in store for 2011.
One of the roadmaps lists no less than 19 upcoming notebook and desktop processors, including a handful of "very low-power" parts with a 35W TDP. These 19 chips run the gamut from dual-core 2.5GHz parts (3.2GHz Turbo) to quad-core 3.4GHz (3.8GHz Turbo) CPUs, including one with an unlocked multiplier (core i7 2600K).
Also on tap from Intel are several new SSDs. Budget buyers will have new X25-E drives to choose from with capacities of up to 400GB, while the X-25M line will get a boost to 600GB.
Today's blistering fast SSDs with read and write speeds approaching 300MB/s have nothing on what's in store for tomorrow. Thanks to a breakthrough in NAND flash memory technology, a Japanese research group says 9.5GB/s SSD writes are entirely possible.
The Cliff Notes version is that the research team found a way to reduce the operating voltage to 1V, resulting in power consumption that's 86 percent lower than existing NAND flash chips, while also overcoming what are called "write disturb" problems. The lower voltage makes it possible for parallel writing to occur on up to 110 NAND chips, or nearly 7 times more than existing NAND flash memory.
The research team calls the procedure the "single-cell self-boost" method, which "turns off two cells adjacent to the unchosen cells by applying a voltage of 1V from both ends of the bit line connected to the unchosen cells so that the channel of the unchosen cells is in the state of floating," as TechON! explains it.
Wrap your head around all the technical jargon here, and then sit back and hope we see this technology manifest itself before SSDs become obsolete.
According to a report published by review site PCPerspective, Intel's advanced sector remapping and wear-leveling algorithm used in the company's X25-M SSD is causing the drive to suffer serious performance degradation over time. In some cases, the site noted reads had been reduced to a pokey 22MB/s. The only solution PCPerspective could come up with to restore the once speedy SSD back to its original performance level was to use a dated version of HDDErase.
Not so fast, says Intel in response to PCPerspctive's claim that the X25-M had become, well, not so fast. Despite the review site having found a drop in performance in all three of its SSDs, Intel claims it has not seen the same type of degradation in its own labs.
"Our labs currently have not been able to duplicate these results," Intel said. "In our estimation, the synthetic workloads they use to stress the drive are not reflective of real world use. Similarly, the benchmarks they used to evaluate performance do not represent what a PC user experiences."
Intel went on to say that it's completely normal for a PC's drive, whether it be an HDD or SSD, to exhibit reduced performance when filled up, but that PCPerspective's results are higher than what Intel would generally expect. Hence the reason why Intel questions the methodology that was used.
Any SSD owners, Intel-brand or otherwise, notice any performance slowdowns over time? Hit the jump and let us know what your experience has been.
No matter how fast or reliable solid state drives become, there will be some who will continue to scoff at the price per gigabyte ratio, particularly as SSDs breach the 256GB mark. That could change if we start to see significant capacity increases in upcoming SSDs, such as the 1TB SSD Pure Silicon was showing off at CES.
Hold your excitement, however, as there's a major rub. While a 1TB SSD sounds like a tantalizing option, pureSilicon doesn't have you, the consumer, in mind. Instead, when the Nitro drives become available in Q3 2009, they will be used for industrial applications, including military, medical, and other such uses. Drats!
Even still, if pureSilicon paves the way to 1TB, it's likely other manufacturers would soon follow. And when they do, it doesn't appear performance will have to be sacrificed to reach higher capacities. The company rates its entire Nitro line, including the 1TB model, at 240MB/s and 215MB/s sustained read and write speeds, respectively, placing it in line with higher performing consumer SSDs.
Do you ever find yourself wondering what to do with those spare SSDs you have lying around? Neither do we, but A-DATA's new XPG Dual SSD 3.5" RAID Enclosure makes a fairly compelling pitch to go out and buy a pair of the pricey drives. Or at least put to use those spare HDDs cluttering your PC room, which is a far more likely scenario.
Whether you want to roll with a pair of SSDs or HDDs, A-DATA's RAID enclosure will accommodate both. By adjusting the hardware DIP switch on the back, users can opt to run each drive independently or in tandem with seven different RAID modes to choose from, including JPOD, RAID 0, RAID 1, Span, SAFE33, SAFE50, or GUI.
A-DATA's multi-purpose enclosure comes with a one-button backup utility and can be used as either an internal or external unit with support for both SATA and USB. The enclosure will also be offered without the built-in RAID function.
Both versions are expected to ship by the end of Q1 2009, and according to TomsHardware, will run roughly $30 for the non-RAID version and $60 with built-in RAID.
