SSDs vs HDDs
Examine the two industry–leading data storage space devices
Today, all of the completely new computers include SSD drives instead of HDD drives. You can see superlatives on them everywhere in the specialized press – they are quicker and function better and they are the future of desktop computer and laptop production.
Nonetheless, how do SSDs fare within the hosting environment? Can they be trustworthy enough to replace the proved HDDs? At CLOUDSTARKS, we are going to aid you much better be aware of the dissimilarities between an SSD and an HDD and decide which one most closely fits you needs.
1. Access Time
SSD drives give a completely new & innovative approach to data safe–keeping based on the use of electronic interfaces rather than any sort of moving parts and turning disks. This brand new technology is way quicker, making it possible for a 0.1 millisecond file access time.
HDD drives still use the very same general data file access concept that’s actually developed in the 1950s. Although it has been significantly improved since then, it’s sluggish in comparison to what SSDs are offering to you. HDD drives’ file access rate varies between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is really important for the performance of a file storage device. We have carried out detailed lab tests and have established that an SSD can deal with no less than 6000 IO’s per second.
Throughout the exact same lab tests, the HDD drives confirmed to be considerably slower, with 400 IO operations addressed per second. Even though this may appear to be a large amount, if you have a busy server that hosts lots of famous sites, a slow harddrive may lead to slow–loading web sites.
3. Reliability
SSD drives do not have just about any rotating components, meaning that there’s significantly less machinery in them. And the fewer actually moving parts there are, the lower the possibilities of failure are going to be.
The typical rate of failing of an SSD drive is 0.5%.
For an HDD drive to function, it has to spin a couple of metal disks at a minimum of 7200 rpm, holding them magnetically stabilized in the air. They have a massive amount of moving components, motors, magnets and other gadgets packed in a small space. So it’s no surprise that the common rate of failing of any HDD drive varies between 2% and 5%.
4. Energy Conservation
SSDs don’t have any moving parts and require minimal chilling power. They also call for a small amount of power to perform – tests have indicated they can be operated by a regular AA battery.
In general, SSDs use up somewhere between 2 and 5 watts.
HDD drives can be notorious for becoming noisy; they can be prone to getting hot and in case there are several disk drives in one hosting server, you need an additional cooling system used only for them.
In general, HDDs use up in between 6 and 15 watts.
5. CPU Power
As a result of SSD drives’ higher I/O effectiveness, the leading web server CPU will be able to process data queries faster and preserve time for different functions.
The common I/O delay for SSD drives is just 1%.
When using an HDD, you have to spend additional time waiting around for the results of your file ask. Consequently the CPU will stay idle for more time, expecting the HDD to reply.
The regular I/O wait for HDD drives is around 7%.
6.Input/Output Request Times
The vast majority of CLOUDSTARKS’s new web servers moved to only SSD drives. Our personal lab tests have shown that with an SSD, the normal service time for any I/O request while doing a backup remains under 20 ms.
Compared to SSD drives, HDDs provide much slower service times for I/O queries. Throughout a web server backup, the normal service time for any I/O call ranges between 400 and 500 ms.
7. Backup Rates
Discussing back ups and SSDs – we have found an exceptional progress with the data backup speed since we switched to SSDs. Right now, a typical web server back–up requires just 6 hours.
On the other hand, on a hosting server with HDD drives, a comparable backup takes 3 to 4 times as long to complete. A complete back up of any HDD–driven web server may take 20 to 24 hours.
The Linux VPS servers and the regular Linux shared hosting service accounts have SSD drives by default. Join our family here, at CLOUDSTARKS, to see how we just might help you improve your web site.
