Servers and SSD Performance
In the fast-evolving landscape of IT, where professionals are constantly seeking ways to overcome performance bottlenecks, attain faster application load times, and even achieve faster boot times, the use of flash memory, specifically solid state drives (SSD), has become a prevalent solution for maximizing server performance.
Maintaining SSD Performance As Fast As New
When it comes to read performance, SSDs outpace standard hard drives significantly. This is primarily attributed to the absence of “seek time” that a traditional hard drive incurs when locating and retrieving data. Unlike hard drives, SSDs utilize an electrical pulse to read data, resulting in a considerably faster process.
Contrary to a common misconception that SSDs, devoid of moving parts, are immune to file fragmentation, the truth is that these drives encounter write speed degradation due to fragmented file write activity and free space fragmentation.
SSD Write Performance
The process of writing data to an SSD presents a distinct challenge. Small free spaces are scattered throughout an SSD volume at the logical level and cause the file system to write a file in fragments to those small free spaces. By doing so, write performance is degraded by as much as 80% to that solid-state storage device.
Additionally, SSDs have a finite number of writes they can perform over their lifespan. Unlike hard drives that can write over old data, SSDs require old data to be erased before new data is written. Due to the doubling effect of needing to read and erase before it can write again, SSDs undergo twice as much use. This doubles the wear and tear and can cause major issues, including shortened lifespan, and slower random write performance. For more technical details, Do SSDs Degrade Over Time?
As an SSD nears its limit, increased fragmentation and write errors occur, resulting in performance slowdowns. Write performance decreases proportionately as free space fragmentation increases. All SSDs will suffer from this problem at one point or another unless DymaxIO® is used to optimize the solid-state drive.
DymaxIO’s IntelliWrite® Technology Restores SSD Write Performance
DymaxIO introduces IntelliWrite, a patented write optimization technology designed to automatically prevent excessively small, fractured, random writes and reads that compromise SSD performance. By enforcing contiguous and sequential writes, IntelliWrite ensures faster and more efficient operations compared to fragmented or random writes. The integration of IntelliWrite into the new DymaxIO fast data performance software guarantees optimal SSD performance, preventing the dreaded performance degradation.
