展开/关闭What Warranty policy of RunCore SSD? RunCore enterprise SSDs come with a standard three years warranty (extendable up to five years on certain high performance enterprise SSDs). Enterprise Value, Read Intensive and Consume SSD Class Drives are not eligible for extended warranty coverage beyond the standard three year warranty.
展开/关闭What is the expected performance increase when using SSD? SSD’s performance is great more than HDD,its IOPS is 100 times than HDD and throughput is 2~3 times than HDD. But,the last effect that adding SSD to system is upon to the way of utilization.
展开/关闭What are the best Use cases & applications for SSDs? SSDs are best suited to applications that require the highest performance. I/O-intensive applications such as databases, data mining, data warehousing, analytics, trading, high-performance computing, server virtualization, Web serving and email system are most suitable for SSD use.

Enterprise SSD FAQs
RunCore CO.,Ltd
• SLC SSD is the preferred technology for write caching, and read caching applications where reads are random and write intensive.
• eMLC SSD will increasingly become the preferred option when handling a mix of both reads and writes, and especially more advantage when budgets are tight.
MLC SSD is the most cost effective solution for read intensive applications such as accessing a database table.
展开/关闭When will the SSD performance start to degrade ?what is the final performance of SSD? The firmware will limit writes if a drive is written heavily or the life span fall to certain value, but read performance remains constant, this is not affected since it will only read all data stored.
展开/关闭For RunCore Kylin family enterprise SSDs,we provides 5 warrant years of after-sale services. RunCore enterprise SSD will not fail even if SSD’s flash memory degraded, it is only allowed read data when the life span reached to 10%.
In addition, The use of an endurance management algorithm ensures that sufficient Program/Erase (P/E) cycles are available for the warranty time period of the drive. The firmware will limit writes if a drive is written heavily. However, customers will rarely see performance throttling when an SSD is used under the intended application.
展开/关闭How about the RunCore SSD’s after-sale service? For RunCore Kylin family enterprise SSDs,we provides 5 warrant years of after-sale services.
展开/关闭How to calculate the SSD Life Span? The life span of SSD is factored by three key parameters: SSD NAND flash technology, capacity of the drive, and the application usage model. In general the following life cycle calculator can be used to figure how long the drive will last.

Life [years] = TBW/(Daily Write x 365days)
TBW ≈ (Capacity×NAND P\E cycling capability×OP factor) / (WLF×WAF);
Daily Write = (SSD Duty Cycle x Write percent x Througput x 3600second x 24 hours)
Parameters:
Endurance, NAND P/E Cycle: 100K SLC, 30K eMLC, 3K MLC
Capacity: Usable capacity of the SSD
Overprovisioning Factor: Over provision NAND percentage
Write Speed: Speed of write in Bytes per second
Duty Cycle: Usage duty cycle
Write %: percentage of writes during SSD usage
WAF: Controller Write Amplification factor computed based on application use case
展开/关闭How to monitor the RunCore SSD’s life time span? RunCore provides Windows & Linux tools to help customer monitor Kylin family SSD’s life time left,if the SSD’s life time left declines to 10%,the SSD will not able to be written.you can download it from RunCore website download center: http://www.runcore.com/en/upgrade.asp
