Silicon Power announced this morning that they have plans to release a 2.5-inch SATA II SSD that will weigh in at a sizeable 256GB.
Doubling the size of their already notable 128GB SSD released previously, the new 256GB version will feature faster read speeds of 165MB/second and write speeds of 98MB/second. Sadly, the drive has a Jmicrion JMF602 controller, which doesn’t play well with SSDs unless it ships with revision B of the very same chip. No word yet on whether or not this is the case.
According to Silicon Power “Customers can easily install the SSD in laptops, PCs or other devices that support SATA II SSD. Silicon Power 2.5” SSD with SATA II or IDE interface is fully compatible with RoHS requirement, with capacities ranging from 8GB to 256GB.”
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.

Ruh-roh, Shaggy, it looks as though SSDs might not be all that and a bag of chips after all. Or more specifically, Intel's mighty X25-M SSD may prove a better sprinter than a marathon runner.
One of the major concerns with SSD technology is that the cells are good only for a finite number of writes, at which point they become read-only. Intel address this potential problem using sector remapping and wear-leveling algorithms, but a new report shows it might carry a nasty performance-reducing side effect.
Most wear-leveling algorithms dynamically move frequently-rewritten logical sectors to different physical sectors of the drive, ensuring that no cells are written to more frequently than others. Intel takes it a step further by extending its remap table into individual sectors, which reduces the number of small block writes needed for small files. The problem, according to PCPerspective, is that Intel's method seriously degrades long-term performance. After two of the site's writers noticed that their X25-M SSDs were performing signicantly slower after a length of time, the review site reran the drives through its gamut of benchmarks and found the drives had indeed degraded in performance, and in some cases, reads were reduced to a paltry 22MB/s. Zoinks!
If you own an X25-M and find that your drive has also slowed down considerably, there are fixes in place. According to Intel, one way to restore performance is to use IOMeter to sequentially write content to the entire drive. PCPerspective said it met with limited success using this method, but had much better results using Intel's second suggestion, which is to use a tool to perform a SECURE ERASE command on the drive. Using an older version of HDDErase (v3.3), the site says it was able to restore its X25-M back to its original performance levels.

The SSD era is fast approaching and Intel would like nothing more than to flood the retail channel with its own branded solid-state drives. To help do that, and to clear out stockpiled inventory, Intel has started offering significant discounts to its channel partners who opt to buy Core i7 processors and SSDs bundled together, says Digitimes.
According to the report, discounts range from 10 to 15 percent and primarily target markets in China, Europe, and North America. For reference, pricing for the company's latest SSDs looks like this:
X25-E 32GB: $410
X18-M 80GB: $385
X25-M 80GB: $385
X18-M 160GB: $760
Intel also plans to launch the X25-E 64GB later this year for $790, before discount. However, it's not a given that the bundled price points will result in less expensive parts for the end-user. There's no stipulation in place that the discount has to be passed on to consumers, and vendors could opt to keep the savings for themselves.
OCZ has been pretty clear that the delays on their Vertex drives was due to the state of their firmware, and now that they appear to have that part out of the way, they’re boasting some mighty impressive numbers.
The latest version of their firmware speeds up sequential read and write performance, so much that it can keep up with Intel’s X-25E Extreme series. But, the Vertex will feature lower prices and higher capacities.
The Indilinx Barefoot SSD controller that the Vertex uses was initially specified to work at 200MB/s sequential read and 160MB/s sequential write, whereas the latest version was able to blow those old numbers out of the water, now moving at 250MB/s sequential read and 240MB/s sequential write.
Intel has recently slashed the prices on their SLC (Single Level Cell) and MLC (Multi Level Cell) SSDs. This move comes in the wake of the failing economy, but also in the interest of helping to keep their competitors, such as OCZ, at bay.
OCZ claims that their series of SSDs have continued to see delays due to firmware reliability and performance. Reportedly many customers are anxious to buy them, but it is notable that OCZ is doing their best to avoid Seagate’s firmware issues.
Intel is planning for a 128GB SLC drive and a 320GB drive using new 34nm MLC chips in late 2009. For the time being though, their price cuts are mighty significant. Their 80GB model is down fro $585 to $390, 160GB down from $945 to $765 and their 32GB is down from $575 to $415.
Many a hardware-encrypted disk has crossed the path of the consumer market lately, but they’ve universally been a questionable investment. All the encryption systems have been proprietary, and you’d be hard pressed to find someone that’s looking to store all their valuable data on a system that can’t be read in a few years down the line.
Thankfully, the Trusted Computing Group has just announced that (almost) every drive maker has agreed on 128-bit encryption for all SSDs and HDDs. The major vendors, such as Fujitsu, Hitachi, Seagate, Samsung, Toshiba, Western Digital, IBM, Wave Systems, LSI and Ulink Technology have all hopped on board.
With any luck we in the consumer market will be looking at simpler disk encryption sometime very soon.
As the NAND flash memory market slowly stabilizes in the later half of this year, it’s expected that SSDs will take over as the primary source of storage for computers industry-wide.
According to research firm DRAMeXchange, the oversupply of NAND flash chips is currently weakening the global SSD market, and is scheduled to balance out. Once this balance happens, the price gap between the HDDs we all currently know and love and the SSDs we all fantasize about and desire will close, ultimately causing a HD-to-SSD replacement cycle that was delayed thanks to the worldwide economic crisis.
Reportedly many computer manufacturers have been preparing for the transition. Many have begun to include SSDs in their laptops, but many desktops are beginning to feature them as well.
Every time Intel sets foot in the SSD market, something good seems to happen. The company's first foray resulted in one of the fastest SSDs yet available with its X-25M boasting read and write speeds of up to 250MB/s and 70MB/s respectively, and now the chip maker wants to boost capacities.
The amount of storage space most SSDs offer has typically been a weak point with the technology to this point, but according Bloomberg, Intel sent a document to its customers telling them to expect a 320GB SSD in the fourth quarter. The comparatively high capacity SSD will be one of eight new drives Intel plans to release, all of which will be built with 32nm chips.
No word yet on pricing or a specific release date, but if released today, the 320GB SSD would be the consumer market's largest capacity to date. However, Toshiba is also working on a high capacity SSD that will offer 512GB of storage and expects to ship the drive in Q2.
Add Corsair to the list of manufacturers now offering SSDs. Like many others before them, the memory maker is focusing on the mainstream market with its SSD debut, but is skipping lower capacity 32GB and 64GB models, at least for the time being, and has jumped straight to 128GB.
Corsair's also skipping the JMicron 602 controller, which is probably a good move considering the associated complaints of stuttering and poor overall performance. Instead, Corsair's S128 will use a Samsung controller and specially-selected Samsung NAND chips. Just don't expect to be blown away by its performance - the MLC-based SSD comes rated at up to 90MB/s and 70MB/s read and write speeds respectively, although Corsair says that faster drivers are in the works.
