SSDs vs HDDs
Discover which storage space device is better for your website hosting account
Nowadays, almost all completely new computers are equipped with SSD drives in lieu of HDD drives. You’ll notice superlatives about them everywhere in the professional press – they are faster and function better and they are actually the future of desktop computer and laptop computer production.
Nevertheless, how do SSDs perform within the web hosting environment? Could they be dependable enough to substitute the proved HDDs? At Bcn Cluster, we’ll help you far better understand the differences between an SSD and an HDD and determine which one most accurately fits you needs.
1. Access Time
Because of a revolutionary new method of disk drive operation, SSD drives allow for considerably faster data file access speeds. With an SSD, data accessibility instances are far lower (as small as 0.1 millisecond).
The concept powering HDD drives dates all the way to 1954. And even while it has been considerably enhanced over the years, it’s nevertheless no match for the inventive ideas driving SSD drives. Using today’s HDD drives, the highest file access speed you can actually reach may differ somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Because of the very same radical approach that enables for quicker access times, you too can get pleasure from better I/O performance with SSD drives. They’re able to perform double the operations within a given time when compared with an HDD drive.
An SSD can deal with at the very least 6000 IO’s per second.
Over the same lab tests, the HDD drives proved to be considerably slower, with 400 IO operations handled per second. Although this may appear to be a significant number, if you have a busy web server that contains many popular websites, a slow hard drive can cause slow–loading web sites.
3. Reliability
SSD drives are made to have as fewer moving parts as is feasible. They use a comparable technology to the one employed in flash drives and are generally much more trustworthy rather than common HDD drives.
SSDs come with an common failing rate of 0.5%.
HDD drives implement rotating disks for saving and reading through info – a concept going back to the 1950s. With disks magnetically hanging in mid–air, spinning at 7200 rpm, the prospects of some thing going wrong are much bigger.
The common rate of failure of HDD drives ranges amongst 2% and 5%.
4. Energy Conservation
SSDs don’t have moving components and require almost no cooling power. Additionally, they involve a small amount of energy to function – trials have established they can be operated by a standard AA battery.
In general, SSDs consume between 2 and 5 watts.
HDD drives are infamous for being noisy; they’re liable to getting too hot and if you have several disk drives within a hosting server, you must have a further a / c unit used only for them.
As a whole, HDDs use up in between 6 and 15 watts.
5. CPU Power
SSD drives allow for faster data access speeds, which generally, in turn, encourage the CPU to finish data file queries faster and afterwards to return to different responsibilities.
The normal I/O hold out for SSD drives is just 1%.
Compared with SSDs, HDDs allow for not so quick data file accessibility speeds. The CPU will be required to wait around for the HDD to come back the requested data, reserving its resources meanwhile.
The common I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
It is time for a few real–world instances. We produced an entire system backup on a web server using only SSDs for data storage reasons. In that operation, the typical service time for an I/O request stayed under 20 ms.
Sticking with the same web server, yet this time loaded with HDDs, the outcome were very different. The common service time for any I/O call changed between 400 and 500 ms.
7. Backup Rates
One more real–life development is the speed with which the backup was made. With SSDs, a server back–up today requires less than 6 hours using Bcn Cluster’s hosting server–enhanced software.
Alternatively, on a hosting server with HDD drives, an identical back up could take three or four times as long in order to complete. An entire back up of any HDD–powered hosting server may take 20 to 24 hours.
Our VPS servers along with the typical cloud website hosting accounts offer SSD drives by default. Be part of our family here, at Bcn Cluster, and see how we just might help you transform your website.
