MTRON SOLID STATE DIGITAL DISK, 7000 SERIES ENTERPRISE EDITION

 

Company Profile

 

In understanding new technology it sometimes helps to have a contextual framework.  When a significant advance in technology is introduced by a smaller, lesser known entity, as opposed to industry giants like Nvidia and Asus, I like to know a little about where my hard earned dollars are going before they are spent.  This is particularly true with a high ticket item like a $1,000+ SSD.  Who is behind product development and, more importantly, warranty and tech support should issues arise?

 

Mtron was the first corporation to mass produce high performance SSD’s for commercial and military industrial applications.  Established in 2005 with a very modest cash infusion of $200,000, the South Korean business has since received financial backing in excess of $7.0M from powerhouses like Hyundai and Digital First Co., while forging R&D relationships with Samsung Electronics and Seoul National University.

 

Before Mtron was aware of my affiliation with Asus Independent, I was already a customer.  I had purchased a 32GB 7000 Series SSD from one of four US distributors.  Mtron enjoys a larger customer base and distribution network in Asia and Europe than it does in the United States.  While its corporate presence in the US is a modest one, its customer service is anything but.  I was enormously impressed by the care, quality and responsiveness of Mtron to the few issues and concerns that arose after my first purchase.  All client support is handled directly by Mtron engineers in South Korea.  Despite geographic and time zone hindrances, Mtron was quick to respond to any questions with thoughtful and detailed answers.

 

Technology

 

Mtron’s SSD’s take an old idea and present it with a healthy infusion of new technology, with the end result being a device that likely replaces conventional hard disk drives.  SSD’s are comprised of arrays of flash memory chips.  The base technology has been around longer than Mtron.  What distinguishes Mtron’s product is its longevity, accuracy and revolutionary error correcting algorithms.  Mtron’s patented Hydra Multiray architecture incorporates four distinct concepts to maximize parallelism utilizing multiple control channels:

 

(1)        Multi-data bus array:  a four channel flash memory bus

(2)        Multi-flash chips array:  four way flash chip interleaving

(3)        Multi-data streams:  simultaneous processing of multiple data streams

(4)        Multi-flash control:  priority-based scheduling for fore and background flash memory access

 

Mtron also introduces an innovation, the patented “Hydra Flash Translation Layer” (FTL), which analyzes requested commands, maps addresses between logical sector numbers and physical flash memory locations and handles data transfer to and from the flash memory.  It’s FTL’s unique algorithm that permits flash memory management and consistent performance for various request patterns.  Specifically, FTL enables:

 

•           Intelligent interleaving

•           Intelligent logical block allocation

•           Intelligent address mapping

 

Lastly, Mtron’s “Hydra Flash Management” algorithm employs three new technologies to ensure data reliability and integrity:

 

(1)        Wear leveling – Dynamic & Static

Since flash memory has a finite number of program and erase cycles, the controller must manage that pattern or the device is vulnerable to failure.  HFM’s wear-leveling algorithm spreads data evenly across the entire drive, supporting both dynamic and static wear-leveling.

(2)        Bad block management

Since flash memory contains bad blocks from inception and accrues new bad blocks during use, HFM’s algorithm was written to detect these bad blocks and substitute reserved blocks in their place, while updating all data contained within.

(3)        7bith BCH ECC

No unlike server RAM, HFM incorporates an error correcting code mechanism to minimize byte errors per page.  HFM can detect and correct errors up to 7 bits per 512byte page.

 

The end result of Hydra Flash Management – and a consideration that helps justify investment in the costly disks – is an extension of average lifespan of a 32GB SSD to 140 years, given 50GB of sequential writing per day.  To give you an idea of how far flash technology has progressed, conventional flash memory has a limited write endurance of 100,000 write/erase cycles, or a MTBF of 5.5 years.   The SSD has a MTBF of 1,000,000 hours.

 

In layman’s terms:  no moving parts, no wear.  ECC:  no data corruption.  Even with a superficial understanding of the technology, it is readily understandable why the military and enterprise data storage environments were early adopters of Mtron’s revolutionary SSD’s, given typical HDD failure of 8.6%.  Power consumption of SSD’s is also approximately one eighth that of the conventional hard disk drive.

 

Product and Pricing

 

Efficiency, longevity and accuracy are not the SSD’s only calling cards.  Perhaps its most dramatic improvement over the antiquated HDD dynamic platter technology is the disk’s sustained read/write speeds.  Mtron’s enterprise computing 7000 Series SSD has 120MB/s read, 90MB/s write speeds.  Its personal line of SSD’s, the Mobi Series, has sustained read/write speeds of 100/80MBs

 

While both series of SSD’s are crafted with high quality materials, the enterprise series is more rugged housed in an aluminum case.  The Mobi series SSD housing is high grade plastic.  Both series come in both 2.5 and 3.5” form factors and have a SATA 1.0a interface.  The SSD’s are available in capacities of 16, 32 and 64GB (the 64GB SSD is only available in the 3.5” form factor).

 

Cost of the SSD’s has hampered their popularity up until recently both in enthusiast circles and more pedestrian applications, such as inclusion in ultra-light notebook computers.  The new Apple MacBook Air employs SSD technology, as do a handful of new ultra-portables.  SSD’s have also found a home in notebooks designed for rugged, field work, as they are far less susceptible to damage and data corruption. 

 

With the cost of a 16GB 3000 Series dropping to $380, the SDD’s have also begun replacing RAM drives in custom built computers used by those in competitive benchmark events.  The faster read and write speeds give power users an edge in benchmarks such as PCMark05 and Geek Bench as is born out in the benchmark section of this review. 

 

The 32GB 3000 Series is priced at $700 and the 64GB SSD, $1,300.  In short, in each given series, one can expect a doubling in price with a doubling in capacity.  There is a marked increase in price point as one progresses to Mtron’s enterprise series of SSD’s.  The 16GB 7000 Series SSD is priced at $759; the 32GB, $1,159; and the 64GB SSD is a staggering $1,959.  This pricing requires adjusted thinking for consumers grown accustomed to high performance terabyte HDD priced at $400.

Comparative Benchmark Scores

 

To fully exploit the read and write speed potential of any SSD, any configuration other than a RAID array on an add-on card is self-defeating.  To illustrate this point, I provide contrasting read tests running four SSD’s in RAID 0 via the Arc-1220 RAID card alongside read tests running an individual SSD via the onboard SATA controller.

User Impressions and Conclusion

Installing Windows XP Professional in 12 minutes total time from beginning to end was the first indication this was not conventional hardware.  Every ten years, we see one or two innovations that forever change the face of personal and enterprise computing.  Mtron’s SSD is such an innovation.  High speed tape backups, the DVD-ROM and, the enthusiast’s favorite, the 8800GTX video card, were all evolutionary in nature.  This was hardware that changed the way computing and software design is approached:  technology that engineers designed for, not around.

I believe the SSD will find a similar legacy as its decreasing price point brings it into popular consumer culture.  With 64GB – 128GB disks still in the $3,000 – 4,000 price range, the higher capacity drives are presently the province of enterprise computing and the military industrial complex. 

Mtron has in the works a more consumer friendly priced series of SSD’s planned for release in the near future.  OCZ Technology has a second generation 32GB SSD priced near the $700 mark with performance figures comparable to Mtron’s 7000 Series slated for release later this month.  MemoRight, another competitor, presently offers a 64GB SSD with 120 MB/s read and write speeds – priced accordingly at $2,089.  There is competition and that will ultimately drive down price to make the SSD a more tenable solution for the enthusiast market.  Lower capacity and more affordable drives like the Mtron Mobi 3000 Series 16GB are still large enough to serve as a boot disk; as such, the SSD is a likely successor to the RAM disks used by competitive benchmarkers.

The SSD's do not generate any heat.  Compared to the average operating temperature of 35C of a high performance HDD like the Western Digital Raptor, this becomes a significant consideration when running RAID arrays of four or more disks. As can be seen in some of the above graphs, the temperature level of the SSD did not shift by so much as 1.0C during the most rigorous of benchmarks.

The absence of moving parts that translates to absence of heat similarly translates to absence of noise.  Any noise.  I became painfully aware of just how much noise pollution conventional hard drives clanking about generate -- and the fans required to keep them cool -- when I disconnected my five HDD Raptor RAID array and connected the four disk Mtron RAID array.  Absolute, sweet silence.  Not all performance differentiation can be reflected by digits and graphs.  Just ask a studio sound engineer.  The lessening of user fatigue following the drop in operating decibels was a welcome benefit of the SSD design.

The raw data stands on its own as a testimonial to the SSD’s very real potential to replace the antiquated dynamic HDD.  Early adopters like Apple Computer will be joined by other notebook and high-end desktop solution providers that wish to remain competitive.
