At present, all of the brand new computer systems come with SSD drives as a substitute for HDD drives. You can see superlatives on them throughout the specialized press – they are a lot quicker and perform far better and they are the future of desktop computer and laptop computer generation.
On the other hand, how can SSDs stand up within the hosting community? Are they efficient enough to substitute the proven HDDs? At Bits Host, we’ll assist you much better comprehend the distinctions in between an SSD and an HDD and judge the one that most closely fits you needs.
1. Access Time
Resulting from a revolutionary new solution to disk drive general performance, SSD drives enable for considerably faster data file accessibility speeds. With an SSD, data access times are much lower (as small as 0.1 millisecond).
HDD drives make use of spinning disks for files storage purposes. When a file is being utilized, you have to await the appropriate disk to get to the correct position for the laser to access the data file in question. This translates into an average access speed of 5 to 8 milliseconds.
2. Random I/O Performance
The random I/O performance is critical for the functionality of any data file storage device. We have carried out in depth tests and have confirmed that an SSD can manage a minimum of 6000 IO’s per second.
During the exact same lab tests, the HDD drives demonstrated that they are considerably slower, with simply 400 IO operations addressed per second. While this might appear to be a great number, if you have an overloaded server that contains a lot of well–liked web sites, a sluggish hard disk drive may result in slow–loading websites.
SSD drives are designed to include as less moving elements as is practical. They utilize an identical technique to the one employed in flash drives and are generally significantly more trustworthy when compared to standard HDD drives.
SSDs have an average failure rate of 0.5%.
HDD drives implement spinning disks for keeping and reading data – a technology since the 1950s. And with disks magnetically hanging in mid–air, spinning at 7200 rpm, the prospect of anything going wrong are generally increased.
The average rate of failure of HDD drives can vary amongst 2% and 5%.
4. Energy Conservation
SSDs do not have moving components and need minimal cooling down power. They also call for a small amount of electricity to operate – tests have revealed that they can be operated by a standard AA battery.
As a whole, SSDs consume somewhere between 2 and 5 watts.
HDD drives are renowned for getting loud. They need more electricity for air conditioning reasons. With a server which includes a variety of HDDs running constantly, you’ll need a great number of fans to ensure they are cool – this will make them far less energy–efficient than SSD drives.
HDDs take in between 6 and 15 watts.
5. CPU Power
The faster the file accessibility speed is, the swifter the file queries can be treated. Consequently the CPU do not need to save assets expecting the SSD to respond back.
The normal I/O wait for SSD drives is actually 1%.
In comparison with SSDs, HDDs allow for reduced file access rates. The CPU will be required to wait for the HDD to send back the requested data file, reserving its resources in the meanwhile.
The typical I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
The vast majority of our completely new machines moved to just SSD drives. Each of our tests have shown that using an SSD, the common service time for an I/O request while running a backup remains below 20 ms.
During the exact same tests using the same server, this time suited out utilizing HDDs, performance was much slower. During the web server back–up procedure, the average service time for any I/O requests ranged somewhere between 400 and 500 ms.
7. Backup Rates
Talking about back ups and SSDs – we have noticed a significant development with the backup speed as we switched to SSDs. Currently, a regular server back up will take solely 6 hours.
Alternatively, on a web server with HDD drives, an identical data backup can take three to four times as long in order to complete. A full back–up of any HDD–equipped hosting server may take 20 to 24 hours.
If you want to instantaneously enhance the overall performance of one’s web sites without needing to adjust any kind of code, an SSD–equipped website hosting solution will be a really good choice. Look at the Linux shared hosting packages packages as well as our Linux VPS web hosting packages – these hosting services feature fast SSD drives and can be found at affordable prices.
