SSDs vs HDDs
Learn which storage service is better for your web hosting account
For years there was one reputable solution to store information on a personal computer – with a hard drive (HDD). On the other hand, this kind of technology is currently displaying its age – hard disks are noisy and sluggish; they’re power–hungry and tend to produce lots of heat in the course of intense procedures.
SSD drives, on the other hand, are really fast, take in far less energy and tend to be far less hot. They offer a whole new way of file access and storage and are years in advance of HDDs when it comes to file read/write speed, I/O operation and power effectivity. Find out how HDDs stand up up against the modern SSD drives.
1. Access Time
Resulting from a radical new solution to disk drive functionality, SSD drives make it possible for faster data file accessibility speeds. With an SSD, file access times are much lower (as little as 0.1 millisecond).
HDD drives even now makes use of the same basic data file access concept that’s actually developed in the 1950s. Though it has been substantially upgraded ever since, it’s slow as compared to what SSDs are offering to you. HDD drives’ file access rate ranges somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Resulting from the brand new revolutionary data storage strategy shared by SSDs, they supply a lot quicker data access speeds and faster random I/O performance.
During Conchtown Hosting’s lab tests, all SSDs revealed their ability to take care of at least 6000 IO’s per second.
Having an HDD drive, the I/O performance gradually raises the more you use the disk drive. Even so, right after it extends to a specific limit, it can’t proceed speedier. And because of the now–old technology, that I/O limit is a lot less than what you could find having an SSD.
HDD are only able to go as far as 400 IO’s per second.
3. Reliability
The absence of moving elements and spinning disks inside SSD drives, and also the recent improvements in electric interface technology have resulted in a substantially less risky file storage device, having a common failure rate of 0.5%.
HDD drives implement spinning hard disks for holding and browsing info – a technology going back to the 1950s. With disks magnetically suspended in mid–air, rotating at 7200 rpm, the prospect of something going wrong are much bigger.
The normal rate of failing of HDD drives ranges between 2% and 5%.
4. Energy Conservation
SSDs don’t have moving parts and require very little chilling power. In addition, they require very little electricity to perform – trials have shown that they can be operated by a regular AA battery.
As a whole, SSDs use up amongst 2 and 5 watts.
As soon as they were created, HDDs have been quite energy–ravenous systems. And when you have a server with several HDD drives, this can increase the per month electric bill.
On average, HDDs use up somewhere between 6 and 15 watts.
5. CPU Power
The speedier the data file access speed is, the faster the file requests will likely be processed. It means that the CPU will not have to reserve assets looking forward to the SSD to respond back.
The average I/O delay for SSD drives is barely 1%.
When using an HDD, you need to invest more time awaiting the outcomes of your data query. This means that the CPU will be idle for more time, waiting for the HDD to reply.
The regular I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
The bulk of Conchtown Hosting’s completely new machines moved to solely SSD drives. Our own tests have revealed that having an SSD, the normal service time for any I/O request whilst running a backup stays below 20 ms.
With the exact same hosting server, however this time furnished with HDDs, the results were very different. The regular service time for an I/O call changed between 400 and 500 ms.
7. Backup Rates
Talking about back ups and SSDs – we’ve spotted an effective improvement with the data backup speed since we turned to SSDs. Now, a usual web server data backup will take solely 6 hours.
We made use of HDDs mainly for a few years and we have got pretty good understanding of precisely how an HDD works. Creating a backup for a server furnished with HDD drives can take about 20 to 24 hours.
With Conchtown Hosting, you can find SSD–operated hosting solutions at inexpensive price points.
