Currently, almost all brand new personal computers contain SSD drives as an alternative for HDD drives. You’ll notice superlatives to them everywhere in the specialised press – that they are a lot quicker and conduct far better and that they are really the future of home computer and laptop computer generation.
Nevertheless, how can SSDs perform inside the hosting environment? Are they trustworthy enough to replace the successful HDDs? At Cheap Unix Host, we’ll assist you to far better understand the distinctions between an SSD and an HDD and decide the one that best suits you needs.
1. Access Time
After the arrival of SSD drives, data accessibility speeds have gone through the roof. Thanks to the brand–new electronic interfaces found in SSD drives, the common data file access time has shrunk to a all–time low of 0.1millisecond.
HDD drives count on rotating disks for data storage purposes. When a file is being utilized, you will need to await the appropriate disk to reach the appropriate place for the laser beam to reach the data file in question. This leads to a typical access speed of 5 to 8 milliseconds.
2. Random I/O Performance
The random I/O performance is vital for the general performance of a data file storage device. We have executed in depth assessments and have confirmed an SSD can manage a minimum of 6000 IO’s per second.
Over the same trials, the HDD drives demonstrated that they are considerably slower, with only 400 IO operations handled per second. Even though this seems to be a large amount, when you have an overloaded server that serves numerous well–known web sites, a slow hard disk could lead to slow–loading web sites.
SSD drives lack any rotating parts, which means there is much less machinery within them. And the fewer actually moving elements you’ll find, the lower the prospect of failure will be.
The average rate of failing of any SSD drive is 0.5%.
With an HDD drive to work, it should rotate 2 metallic disks at over 7200 rpm, having them magnetically stabilized in the air. There is a massive amount of moving elements, motors, magnets and other gadgets loaded in a small place. Hence it’s no wonder that the average rate of failing of an HDD drive can vary between 2% and 5%.
4. Energy Conservation
SSDs are lacking moving parts and need not much chilling power. They also demand not much energy to perform – lab tests have demonstrated that they can be operated by a standard AA battery.
In general, SSDs use up amongst 2 and 5 watts.
From the time they have been designed, HDDs have always been extremely electrical power–ravenous products. And when you’ve got a server with a couple of HDD drives, this will likely increase the per month electric bill.
Normally, HDDs use up between 6 and 15 watts.
5. CPU Power
The swifter the file accessibility speed is, the faster the data file queries will likely be adressed. Consequently the CPU do not need to reserve resources waiting around for the SSD to answer back.
The normal I/O wait for SSD drives is barely 1%.
Compared with SSDs, HDDs permit not so quick data accessibility rates. The CPU is going to await the HDD to come back the inquired file, scheduling its allocations in the meanwhile.
The average I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
The bulk of our brand–new servers now use simply SSD drives. Our own tests have demostrated that having an SSD, the average service time for any I/O request although building a backup remains below 20 ms.
In comparison to SSD drives, HDDs deliver much slower service rates for I/O queries. In a web server backup, the standard service time for any I/O query varies somewhere between 400 and 500 ms.
7. Backup Rates
Discussing backups and SSDs – we have detected an amazing progress with the back–up rate as we moved to SSDs. Now, a usual hosting server back up requires simply 6 hours.
We applied HDDs exclusively for a couple of years and we have great understanding of exactly how an HDD works. Generating a backup for a server designed with HDD drives will take around 20 to 24 hours.
