For years there was only one dependable option to keep information on your personal computer – having a disk drive (HDD). Nevertheless, this type of technology is presently expressing it’s age – hard disks are really loud and sluggish; they can be power–ravenous and frequently produce quite a lot of warmth throughout serious operations.
SSD drives, on the contrary, are extremely fast, take in a smaller amount energy and are far less hot. They feature an exciting new approach to file accessibility and storage and are years in advance of HDDs in relation to file read/write speed, I/O operation and then energy efficiency. Observe how HDDs stand up against the modern SSD drives.
1. Access Time
With the release of SSD drives, file access rates are now through the roof. Due to the brand–new electronic interfaces utilized in SSD drives, the standard data file access time has shrunk into a record low of 0.1millisecond.
The concept behind HDD drives goes all the way to 1954. Even though it’s been substantially enhanced throughout the years, it’s nevertheless no match for the inventive technology behind SSD drives. With today’s HDD drives, the top data access speed you’ll be able to achieve may differ between 5 and 8 milliseconds.
2. Random I/O Performance
On account of the unique radical data storage method adopted by SSDs, they supply speedier data access speeds and quicker random I/O performance.
In the course of our tests, all SSDs confirmed their ability to work with at the least 6000 IO’s per second.
During the exact same tests, the HDD drives confirmed to be significantly slower, with only 400 IO operations managed per second. Even though this feels like a significant number, when you have a busy web server that serves loads of famous websites, a slow harddrive may lead to slow–loading web sites.
The absence of moving elements and rotating disks inside SSD drives, and also the latest developments in electric interface technology have led to an extremely less risky data storage device, having an normal failure rate of 0.5%.
HDD drives make use of rotating hard disks for storing and reading data – a concept going back to the 1950s. With hard disks magnetically hanging in mid–air, rotating at 7200 rpm, the probability of anything going wrong are usually bigger.
The normal rate of failure of HDD drives can vary among 2% and 5%.
4. Energy Conservation
SSDs are lacking moving elements and need very little cooling down power. Additionally they require a small amount of electricity to operate – tests have indicated they can be powered by a normal AA battery.
In general, SSDs use up amongst 2 and 5 watts.
From the moment they were designed, HDDs have always been really electric power–hungry equipment. When you’ve got a server with a bunch of HDD drives, this can increase the regular monthly utility bill.
On average, HDDs consume between 6 and 15 watts.
5. CPU Power
As a result of SSD drives’ better I/O functionality, the key hosting server CPU can easily process data file requests a lot quicker and conserve time for other operations.
The normal I/O delay for SSD drives is exactly 1%.
HDD drives allow for reduced access speeds when compared with SSDs do, resulting for the CPU required to delay, whilst arranging allocations for your HDD to discover and return the inquired file.
The regular I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
It’s time for some real–world cases. We, at Site Gods, competed a full system backup on a hosting server only using SSDs for data storage purposes. In that operation, the normal service time for any I/O query stayed beneath 20 ms.
Weighed against SSD drives, HDDs deliver noticeably reduced service times for input/output queries. In a server backup, the regular service time for an I/O call can vary between 400 and 500 ms.
7. Backup Rates
One more real–life improvement will be the speed at which the back up was made. With SSDs, a hosting server back–up currently takes less than 6 hours implementing our web server–enhanced software solutions.
We used HDDs mainly for a couple of years and we have very good understanding of precisely how an HDD works. Backing up a hosting server furnished with HDD drives can take around 20 to 24 hours.
