Currently, pretty much all new laptops or computers include SSD drives as opposed to HDD drives. One can find superlatives about them everywhere in the professional press – they are quicker and perform far better and they are actually the future of home computer and laptop computer manufacturing.
Even so, how do SSDs perform in the hosting community? Can they be well–performing enough to replace the successful HDDs? At AtmoVantage, we are going to make it easier to much better be aware of the distinctions in between an SSD and an HDD and choose the one that best suits you needs.
1. Access Time
With the introduction of SSD drives, file access rates have gone tremendous. Because of the brand new electronic interfaces found in SSD drives, the common data file access time has shrunk towards a record low of 0.1millisecond.
HDD drives depend on rotating disks for files storage reasons. Each time a file will be used, you will have to wait around for the right disk to reach the right position for the laser beam to access the data file in question. This results in a typical access rate of 5 to 8 milliseconds.
2. Random I/O Performance
Caused by the brand–new significant file storage technique adopted by SSDs, they provide faster data access speeds and faster random I/O performance.
All through AtmoVantage’s tests, all SSDs confirmed their ability to deal with at least 6000 IO’s per second.
With an HDD drive, the I/O performance progressively enhances the more you apply the hard drive. Having said that, in the past it actually reaches a certain cap, it can’t get speedier. And due to the now–old technology, that I/O cap is noticeably lower than what you could find having an SSD.
HDD can only go as much as 400 IO’s per second.
SSD drives do not have virtually any moving parts, meaning there is a lesser amount of machinery in them. And the less actually moving components you will find, the lower the chances of failure will be.
The normal rate of failure of any SSD drive is 0.5%.
Since we have already mentioned, HDD drives make use of rotating disks. And anything that works by using plenty of moving elements for continuous periods of time is vulnerable to failure.
HDD drives’ common rate of failure ranges somewhere between 2% and 5%.
4. Energy Conservation
SSD drives are usually smaller than HDD drives and also they do not have virtually any moving components at all. It means that they don’t create just as much heat and need considerably less electricity to work and fewer power for cooling down purposes.
SSDs use up between 2 and 5 watts.
From the minute they were developed, HDDs have always been very electricity–heavy devices. And when you’ve got a web server with quite a few HDD drives, this will boost the regular power bill.
On average, HDDs take in somewhere between 6 and 15 watts.
5. CPU Power
As a result of SSD drives’ better I/O efficiency, the main hosting server CPU will be able to process data requests more rapidly and save time for other operations.
The average I/O wait for SSD drives is 1%.
When using an HDD, you have to spend additional time anticipating the results of your data ask. As a result the CPU will be idle for much more time, looking forward to the HDD to respond.
The normal I/O wait for HDD drives is around 7%.
6.Input/Output Request Times
In the real world, SSDs perform as perfectly as they managed throughout AtmoVantage’s tests. We ran a complete platform backup on one of our own production machines. Through the backup operation, the average service time for I/O demands was basically below 20 ms.
All through the exact same tests with the same server, this time suited out using HDDs, performance was substantially slow. During the server back up process, the common service time for any I/O calls ranged between 400 and 500 ms.
7. Backup Rates
Speaking about backups and SSDs – we’ve discovered a fantastic progress in the backup speed since we transferred to SSDs. Currently, a usual hosting server backup takes just 6 hours.
We made use of HDDs exclusively for a few years and we have now pretty good expertise in exactly how an HDD performs. Creating a backup for a hosting server furnished with HDD drives will take around 20 to 24 hours.
