Nowadays, all of the new computer systems come with SSD drives as a substitute for HDD drives. You will see superlatives on them throughout the professional press – that they’re faster and conduct better and that they are the future of home computer and laptop computer manufacturing.
Even so, how do SSDs fare within the web hosting environment? Can they be well–performing enough to replace the established HDDs? At Souq Hosting, we will help you far better understand the differences in between an SSD as well as an HDD and choose which one most closely fits you needs.
1. Access Time
With the launch of SSD drives, file accessibility rates are now through the roof. As a result of brand–new electronic interfaces found in SSD drives, the common data file access time has shrunk into a record low of 0.1millisecond.
HDD drives even now take advantage of the very same basic data access concept that was actually created in the 1950s. Even though it has been significantly improved since that time, it’s sluggish compared with what SSDs are offering. HDD drives’ data file access rate ranges somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is very important for the operation of a data storage device. We have executed substantial exams and have identified an SSD can deal with at least 6000 IO’s per second.
Throughout the very same trials, the HDD drives confirmed to be much slower, with 400 IO operations managed per second. Even though this looks like a large number, for those who have an overloaded web server that contains numerous popular sites, a sluggish hard disk may result in slow–loading websites.
The absence of moving components and spinning disks in SSD drives, as well as the current advances in electric interface technology have generated an extremely reliable file storage device, having an average failure rate of 0.5%.
HDD drives work with spinning disks for storing and browsing data – a concept since the 1950s. Along with hard disks magnetically hanging in mid–air, rotating at 7200 rpm, the likelihood of some thing failing are generally bigger.
The common rate of failing of HDD drives varies between 2% and 5%.
4. Energy Conservation
SSD drives are considerably smaller compared to HDD drives as well as they don’t possess any moving components at all. It means that they don’t produce just as much heat and need considerably less power to function and fewer energy for chilling reasons.
SSDs use up amongst 2 and 5 watts.
HDD drives are known for becoming noisy; they can be more likely to overheating and when you have several disk drives in one web server, you have to have a further a / c unit exclusively for them.
As a whole, HDDs take in between 6 and 15 watts.
5. CPU Power
Thanks to SSD drives’ better I/O performance, the key web server CPU will be able to process file requests much faster and save time for other operations.
The normal I/O delay for SSD drives is 1%.
HDD drives accommodate sluggish accessibility rates when compared with SSDs do, resulting in the CPU required to delay, whilst scheduling allocations for your HDD to find and return the demanded data.
The regular I/O delay for HDD drives is around 7%.
6.Input/Output Request Times
Almost all of Souq Hosting’s completely new web servers moved to only SSD drives. Our own tests have demostrated that with an SSD, the typical service time for any I/O request whilst operating a backup continues to be below 20 ms.
In contrast to SSD drives, HDDs feature considerably sluggish service times for input/output demands. During a web server backup, the standard service time for an I/O request can vary between 400 and 500 ms.
7. Backup Rates
Another real–life improvement will be the rate at which the data backup has been developed. With SSDs, a server back up now can take less than 6 hours by making use of Souq Hosting’s web server–optimized software solutions.
Alternatively, on a web server with HDD drives, a comparable backup can take three to four times as long in order to complete. A complete backup of any HDD–driven web server often takes 20 to 24 hours.
