For decades there seemed to be just one single reliable path to keep data on your personal computer – employing a hard disk drive (HDD). On the other hand, this type of technology is already displaying its age – hard disk drives are really noisy and sluggish; they can be power–hungry and tend to produce a great deal of warmth throughout intense procedures.

SSD drives, in contrast, are quick, use up a lot less power and tend to be far less hot. They furnish a new method of file access and data storage and are years in advance of HDDs with regards to file read/write speed, I/O operation and energy efficiency. Observe how HDDs fare up against the more recent SSD drives.

1. Access Time

Due to a revolutionary new method of disk drive general performance, SSD drives make it possible for faster file accessibility speeds. With an SSD, data accessibility times tend to be lower (under 0.1 millisecond).

Image

HDD drives continue to utilize the exact same basic data access concept that’s originally created in the 1950s. Even though it was vastly improved since then, it’s slower when compared with what SSDs will offer. HDD drives’ file access rate ranges somewhere between 5 and 8 milliseconds.

2. Random I/O Performance

Due to the very same revolutionary approach that permits for faster access times, it’s also possible to experience greater I/O efficiency with SSD drives. They will complete double as many operations during a specific time in comparison with an HDD drive.

An SSD can handle at the least 6000 IO’s per second.

Image

During the exact same lab tests, the HDD drives demonstrated to be significantly slower, with 400 IO operations maintained per second. Even though this may seem like a significant number, if you have a busy server that hosts plenty of well–known sites, a sluggish hard drive can result in slow–loading web sites.

3. Reliability

Image

The lack of moving parts and rotating disks within SSD drives, as well as the current improvements in electrical interface technology have generated a much less risky data storage device, with a typical failure rate of 0.5%.

Image

For the HDD drive to work, it has to spin 2 metal disks at over 7200 rpm, keeping them magnetically stable in the air. They have a good deal of moving parts, motors, magnets along with other devices crammed in a small space. So it’s no wonder that the regular rate of failing of an HDD drive varies in between 2% and 5%.

4. Energy Conservation

Image

SSDs don’t have any moving elements and need minimal cooling energy. They also require very little power to perform – tests have revealed that they can be powered by a common AA battery.

In general, SSDs consume between 2 and 5 watts.

Image

HDD drives are renowned for becoming loud. They need more electric power for cooling purposes. On a web server that has several HDDs running constantly, you need a great number of fans to keep them kept cool – this will make them a lot less energy–economical than SSD drives.

HDDs use up somewhere between 6 and 15 watts.

5. CPU Power

Image

SSD drives permit speedier file access speeds, that, consequently, enable the CPU to complete data requests faster and then to return to additional jobs.

The common I/O hold out for SSD drives is actually 1%.

Image

HDD drives enable reduced access rates as opposed to SSDs do, resulting for the CPU having to hold out, although arranging allocations for the HDD to find and return the required data file.

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

6.Input/Output Request Times

Image

The vast majority of ModuLogix’s brand new servers are now using exclusively SSD drives. Our personal lab tests have demostrated that by using an SSD, the normal service time for an I/O request although running a backup stays below 20 ms.

Image

Compared with SSD drives, HDDs offer significantly slower service times for I/O requests. Throughout a web server backup, the common service time for any I/O request ranges between 400 and 500 ms.

7. Backup Rates

Image

Speaking about backups and SSDs – we have noticed a significant advancement in the back–up speed since we switched to SSDs. Today, a typical hosting server back–up will take simply 6 hours.

Image

Throughout the years, we’ve got utilized principally HDD drives with our machines and we’re well aware of their efficiency. On a web server designed with HDD drives, a complete hosting server back up usually takes around 20 to 24 hours.

Our VPS packages and also the routine Linux cloud web hosting accounts include SSD drives automatically. Be part of our ModuLogix family, to see the way we just might help you boost your website.
