Windows 10: Understanding SSD Positioning and Endurance - a good read!

Hi all -

Just wanted to share this article by Western Digital as it is well written and not too technical:

Understanding SSD Endurance

Hope that this is a useful resource.

SSD Endurance

The SSD Endurance Experiment: Two freaking petabytes - The Tech Report


Interesting article where they've been testing the write failure rate of some SSDs. the details of the tests they perform are in one of their original articles, but this one gives a good over view of what's been going on, if you don't want deep details.

 

Industry Survey Identifies Improved SSD Endurance as Key to Enterprise SSD Adoption

SMART Storage Systems, an innovative enterprise solid-state drive (SSD) technology provider, today announced the results of an international industry survey revealing that 77 percent of respondents believe NAND Flash endurance is the key to widespread SSD adoption in the enterprise. Further underscoring the need for improved endurance of more cost-effective multi-level cell (MLC) NAND Flash, 55 percent of respondents identified cost as the primary barrier to transitioning to an all-Flash enterprise storage environment.

The SMART Storage Systems survey was conducted at the company's exposition booth during the 2012 Flash Memory Summit, VMworld 2012, SNW Fall (U.S.) 2012, and SNW Europe 2012 conferences, collecting 722 responses. Survey participants included IT management and infrastructure professionals, storage architects, and engineering and product managers from the United States and Europe.

Viewed by many as the answer to server and storage bottlenecks, the survey found that 52 percent of organizations currently leverage SSDs in their environment, either in all-Flash architectures, or SSDs combined with traditional hard-disk drives (HDDs). Seeking a balance between cost, performance and endurance, many data center managers look to consumer-grade MLC Flash-based SSDs. However, due to its inherently low endurance, MLC-based SSDs quickly wear out in write intensive enterprise workloads, requiring organizations to replace their SSDs multiple times during the warranty period thereby increasing the total cost of ownership (TCO). While 59 percent of the survey's respondents believe that MLC Flash is enterprise ready, 72 percent rated the endurance of their current SSDs as a seven or below on a 10 point scale, resulting in slower penetration of SSDs in enterprise environments due to the need to replace drives within the stated warranty period.

In addition to highlighting the need for endurance enhanced MLC NAND Flash, the survey also spotlighted key factors that data center purchasers consider when evaluating solutions, including:

• 41 percent of respondents say performance is the most important characteristic when evaluating SSDs, with reliability and endurance rounding out the top three.
• 40 percent of respondents would choose MLC if they were the storage purchase decision maker for their data center, compared to 30 percent for single-level cell (SLC).
• Only seven percent of respondents would select triple-level cell (TLC) NAND Flash for their enterprise environment, if it were available.

"Since SSDs became a viable option for the enterprise performance, cost and reliability have been critical points of evaluation. However, as IT purchasers begin to better understand the technology's strengths and weaknesses, we are seeing more importance placed on the balance between endurance and cost," said John Scaramuzzo, president of SMART Storage Systems. "We have always believed that endurance is the key to making SSDs truly viable in the enterprise. Our Guardian Technology Platform enables consumer-grade MLC Flash to reach up to 50 drive writes per day, enabling SSDs to strike the balance between performance, reliability, cost and endurance, and meet the requirements of nearly any enterprise application."

 

Sun and Samsung Develop Ultra-Endurance SSD memory

thats what it should read, with the price of current offerings Ultra_Expensive is what it will be, but definately a step in the right direction as far as development is concerned

i cant see ssd being mainstream for AT LEAST another 5-10 years
