What is an SSD?
An SSD (Solid State Drive) is superior hardware, a non-volatile storage device that stores persistent data on solid-state flash memory. This technology uses electronic interfaces compatible to block input/output hard disk drives, which permit simple replacements in common applications. SSD does not have a mechanical arm to perform read and write operations. Instead, it uses an embedded processor known as a controller to perform a bunch of reading and writing operations.
A website, blog, or any online application may require a lot of database input and output, and increase in popularity of your website may lead you to get more traffic to your site. Due to the number of users, your hard drive will get more I/O requests and may slow down the speed of generating information from your database. This is the main limitation of HDD, as it consists of a spinning head that restricts the amount of information requested at a given time. To overcome this restriction, a drive was introduced known as SSD. As it lacks moving parts, and only network speed can slow down the data transfer rate of SSD. Particularly, an SSD can be more than 100 times faster than ordinary HDD regarding I/O operations.
Access time is crucial for dynamic data driven and concurrently high traffic generating websites like Facebook, Twitter, LinkedIn, etc. A traditional hard disk drive may take 15-20ms to process a request whereas SSD can process it in just 0.2ms. So, in terms of speed SSDs are more advantageous over HDDs.
SSD hosting is required to accelerate the process of retrieving information from the file system and database of websites that make use of CMS like WordPress, Joomla, Drupal, etc.
How SSDs are more advantageous over HDDs?
A server with an SSD can read data much faster than a standard HDD as it does not contain physical moving parts and is based on solid-state flash memory. They are more resistant to shocks, run quietly, have lower access times, and less latency than an HDD.
Some of the benefits of SSDs are listed below:
- Better performance
- Environmentally friendly
Cons/Disadvantages of SDDs
Along with the benefits listed above SSDs also have some disadvantages listed below:
- More Expensive
- Limited Storage Capacity
What about SSD Caching?
SSD Caching involves storing “hot” data (data frequently accessed by the server) while less frequently accessed data is stored on HDDs. SSD caching is quite the marketing gimmick, as you (the client) may not even know the size of the SSD that caches the frequently accessed data, You’re also not guaranteed that your data will ever get cached, or even stay in the cache long enough to matter. Furthermore, SSD caching will be shared by all the clients on the server – which will give you fewer chances of taking an advantage of the cache.
How does pure SSD storage play a major role?
The SSD web hosting that we offer is built with hardware RAID10 arrays of pure SSD storage.
RAID10 is mirroring and striping which gives rise to further better performance and Fastpath being able to double the transactional performance using any SSD.
Ultimately, SSDs are much faster, better on the environment, and more durable than HDDs. At Localnode, we only use pure SSD storage on our servers. If you’re looking for lightning fast response times, and fast hosting – we do it better.
