SSDs vs HDDs
See the Pro’s and Con’s of HDD and SSD drives
Today, all of the completely new computing devices are equipped with SSD drives as opposed to HDD drives. You can see superlatives to them all around the professional press – they are quicker and operate much better and they are the future of desktop computer and laptop generation.
Then again, how can SSDs fare within the web hosting environment? Could they be reliable enough to replace the proved HDDs? At eTesLa Servers, we’ll help you better understand the dissimilarities in between an SSD and an HDD and decide the one that most closely fits you needs.
1. Access Time
Resulting from a revolutionary new solution to disk drive performance, SSD drives allow for considerably quicker data accessibility rates. Having an SSD, data file access instances tend to be lower (as small as 0.1 millisecond).
The technology behind HDD drives dates back to 1954. And even while it has been considerably refined through the years, it’s even now can’t stand up to the revolutionary technology behind SSD drives. Through today’s HDD drives, the highest data access rate you can actually attain may differ in between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is very important for the efficiency of a data storage device. We’ve carried out extensive tests and have confirmed an SSD can manage no less than 6000 IO’s per second.
With an HDD drive, the I/O performance gradually increases the more you employ the drive. Nevertheless, in the past it extends to a specific limit, it can’t go faster. And because of the now–old concept, that I/O restriction is significantly lower than what you can find with an SSD.
HDD can only go as much as 400 IO’s per second.
3. Reliability
SSD drives are lacking any rotating components, which means there’s a lesser amount of machinery in them. And the fewer actually moving elements you can find, the fewer the likelihood of failure can be.
The common rate of failure of an SSD drive is 0.5%.
For an HDD drive to operate, it has to rotate 2 metal disks at more than 7200 rpm, holding them magnetically stable in the air. There is a large amount of moving components, motors, magnets along with other gadgets packed in a tiny space. Consequently it’s no wonder that the standard rate of failure of any HDD drive ranges somewhere between 2% and 5%.
4. Energy Conservation
SSD drives work practically silently; they don’t create excess warmth; they don’t require supplemental air conditioning alternatives as well as consume much less power.
Lab tests have established that the common electrical power consumption of an SSD drive is between 2 and 5 watts.
From the moment they have been constructed, HDDs have been very electric power–heavy products. So when you have a web server with lots of HDD drives, this tends to add to the regular monthly electricity bill.
Normally, HDDs use up somewhere between 6 and 15 watts.
5. CPU Power
Because of SSD drives’ better I/O functionality, the leading hosting server CPU will be able to work with data file demands faster and preserve time for different functions.
The common I/O delay for SSD drives is just 1%.
When you use an HDD, you will have to dedicate extra time waiting for the outcome of one’s file call. As a result the CPU will continue to be idle for additional time, waiting around for the HDD to reply.
The regular I/O delay for HDD drives is around 7%.
6.Input/Output Request Times
In real life, SSDs conduct as perfectly as they managed during the tests. We ran an entire system back–up on one of the production web servers. Through the backup procedure, the common service time for I/O calls was indeed below 20 ms.
Sticking with the same server, however this time furnished with HDDs, the end results were totally different. The standard service time for an I/O query fluctuated somewhere between 400 and 500 ms.
7. Backup Rates
Speaking about back ups and SSDs – we’ve found a significant progress in the data backup speed as we moved to SSDs. Now, a normal hosting server data backup requires simply 6 hours.
On the other hand, on a server with HDD drives, a comparable back up takes 3 to 4 times as long in order to complete. A complete back–up of any HDD–equipped web server often takes 20 to 24 hours.
