SSDs vs HDDs
Check out the Pro’s and Con’s of HDD and SSD drives
Currently, almost all new computer systems contain SSD drives as an alternative to HDD drives. You’ll find superlatives about them everywhere in the specialized press – they are faster and perform far better and they are the future of desktop computer and laptop computer production.
Having said that, how do SSDs perform inside the website hosting community? Are they well–performing enough to substitute the proved HDDs? At nrovia.com, we will make it easier to much better see the dissimilarities in between an SSD as well as an HDD and determine which one best suits you needs.
1. Access Time
Because of a radical new method of disk drive performance, SSD drives make it possible for much faster data file access rates. With an SSD, data access instances are far lower (as low as 0.1 millisecond).
The concept behind HDD drives goes all the way back to 1954. And while it’s been considerably processed throughout the years, it’s even now can’t stand up to the ground breaking ideas driving SSD drives. With today’s HDD drives, the top file access rate you are able to attain may differ somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is important for the functionality of any data storage device. We have conducted substantial lab tests and have confirmed an SSD can manage a minimum of 6000 IO’s per second.
Hard drives provide slower data access rates due to older file storage space and accessibility concept they are implementing. And they also exhibit considerably sluggish random I/O performance as opposed to SSD drives.
For the duration of our lab tests, HDD drives addressed on average 400 IO operations per second.
3. Reliability
The absence of moving components and rotating disks within SSD drives, as well as the latest advances in electrical interface technology have resulted in a substantially safer file storage device, having a common failing rate of 0.5%.
To have an HDD drive to operate, it needs to rotate two metallic hard disks at more than 7200 rpm, retaining them magnetically stable in mid–air. They have a many moving parts, motors, magnets and other devices crammed in a small location. Therefore it’s no wonder that the regular rate of failure of any HDD drive ranges among 2% and 5%.
4. Energy Conservation
SSD drives work virtually noiselessly; they don’t create extra heat; they don’t mandate added cooling options and consume significantly less power.
Lab tests have demonstrated the normal electric power intake of an SSD drive is somewhere between 2 and 5 watts.
From the minute they have been designed, HDDs have always been really electricity–heavy equipment. So when you have a hosting server with many different HDD drives, this will add to the per month electricity bill.
On average, HDDs consume in between 6 and 15 watts.
5. CPU Power
SSD drives support quicker file accessibility speeds, which will, in return, enable the processor to accomplish file queries considerably quicker and after that to return to other duties.
The typical I/O wait for SSD drives is barely 1%.
HDD drives enable reduced accessibility speeds when compared to SSDs do, which will result in the CPU being required to hold out, whilst reserving resources for your HDD to discover and return the requested data file.
The standard I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
It’s time for a few real–world instances. We, at nrovia.com, ran a detailed platform backup on a hosting server using only SSDs for file storage purposes. In that operation, the regular service time for an I/O request stayed below 20 ms.
In comparison to SSD drives, HDDs offer noticeably reduced service rates for input/output queries. Throughout a server backup, the average service time for any I/O query varies somewhere between 400 and 500 ms.
7. Backup Rates
A different real–life advancement is the speed at which the backup was developed. With SSDs, a web server data backup today takes only 6 hours implementing nrovia.com’s web server–enhanced software solutions.
We applied HDDs exclusively for several years and we have now great understanding of just how an HDD works. Creating a backup for a server furnished with HDD drives is going to take around 20 to 24 hours.
The shared hosting accounts offer SSD drives by default. Be a part of our nrovia.com family, and find out how we just might help you help your site.
