For decades there was just one single reliable way to keep information on your computer – having a hard drive (HDD). However, this type of technology is already displaying its age – hard drives are really noisy and sluggish; they are power–ravenous and have a tendency to generate lots of heat in the course of serious operations.

SSD drives, however, are swift, take in far less energy and they are far less hot. They offer an exciting new solution to file access and storage and are years in front of HDDs when considering file read/write speed, I/O efficiency as well as power efficiency. Figure out how HDDs stand up up against the modern SSD drives.

1. Access Time

SSD drives offer a fresh & innovative way of file safe–keeping based on the use of electronic interfaces in lieu of any kind of moving components and spinning disks. This new technology is faster, making it possible for a 0.1 millisecond data accessibility time.

Image

HDD drives even now utilize the same general file access technique which was initially developed in the 1950s. Although it has been much advanced after that, it’s sluggish in comparison with what SSDs will offer. HDD drives’ file access rate can vary in between 5 and 8 milliseconds.

2. Random I/O Performance

Image

The random I/O performance is critical for the performance of any data storage device. We’ve carried out detailed testing and have identified that an SSD can deal with at the least 6000 IO’s per second.

Image

Having an HDD drive, the I/O performance progressively improves the more you employ the hard drive. Even so, once it actually reaches a specific limitation, it can’t go quicker. And because of the now–old technology, that I/O restriction is a lot less than what you can have having an SSD.

HDD are only able to go so far as 400 IO’s per second.

3. Reliability

Image

The lack of moving components and rotating disks inside SSD drives, and also the latest developments in electronic interface technology have led to a considerably risk–free data storage device, having a typical failing rate of 0.5%.

Image

HDD drives utilize rotating disks for holding and browsing info – a concept going back to the 1950s. With hard disks magnetically hanging in the air, rotating at 7200 rpm, the probability of one thing failing are usually bigger.

The standard rate of failing of HDD drives varies amongst 2% and 5%.

4. Energy Conservation

Image

SSDs don’t have moving parts and need not much cooling energy. Additionally, they involve not much power to operate – trials have demonstrated that they’ll be operated by a normal AA battery.

As a whole, SSDs take in somewhere between 2 and 5 watts.

Image

From the moment they were developed, HDDs were always really power–greedy products. When you have a server with many types of HDD drives, this will likely increase the per month utility bill.

On average, HDDs consume in between 6 and 15 watts.

5. CPU Power

Image

Thanks to SSD drives’ higher I/O performance, the main server CPU can process data queries more quickly and preserve time for different operations.

The standard I/O delay for SSD drives is exactly 1%.

Image

If you use an HDD, you have to dedicate time waiting around for the results of your file request. This means that the CPU will be idle for much more time, waiting around for the HDD to react.

The regular I/O wait for HDD drives is around 7%.

6.Input/Output Request Times

Image

The majority of our new servers moved to only SSD drives. Our very own tests have indicated that by using an SSD, the typical service time for an I/O request whilst performing a backup stays below 20 ms.

Image

In contrast to SSD drives, HDDs offer considerably sluggish service times for I/O requests. Throughout a web server backup, the normal service time for an I/O request varies somewhere between 400 and 500 ms.

7. Backup Rates

Image

You can easily notice the real–world potential benefits to using SSD drives every day. By way of example, on a server pre–loaded with SSD drives, a complete back up can take only 6 hours.

Image

We made use of HDDs mainly for lots of years and we have got pretty good knowledge of just how an HDD performs. Creating a backup for a server designed with HDD drives can take about 20 to 24 hours.
