For decades there was one dependable way for you to keep info on a personal computer – employing a hard drive (HDD). On the other hand, this kind of technology is currently displaying it’s age – hard disk drives are actually loud and sluggish; they’re power–ravenous and are likely to produce lots of heat throughout intensive operations.

SSD drives, in contrast, are swift, take in a lesser amount of power and they are much cooler. They feature a brand new approach to file accessibility and data storage and are years in front of HDDs with regards to file read/write speed, I/O performance and then energy capability. See how HDDs fare against the more recent SSD drives.

1. Access Time

Image

After the arrival of SSD drives, data access rates have gone over the top. Thanks to the brand new electronic interfaces found in SSD drives, the common data file access time has been reduced towards a record low of 0.1millisecond.

Image

HDD drives still utilize the very same general file access technique that was originally developed in the 1950s. Though it has been much advanced since then, it’s slower in comparison to what SSDs will offer. HDD drives’ data access speed ranges somewhere between 5 and 8 milliseconds.

2. Random I/O Performance

Image

The random I/O performance is extremely important for the operation of any data file storage device. We’ve carried out detailed trials and have determined an SSD can manage no less than 6000 IO’s per second.

Image

Throughout the same tests, the HDD drives demonstrated that they are significantly slower, with only 400 IO operations maintained per second. While this feels like a large amount, for those who have an overloaded server that hosts a lot of popular web sites, a sluggish disk drive can cause slow–loading websites.

3. Reliability

Image

SSD drives are made to have as less moving components as is practical. They use an identical technology to the one employed in flash drives and are also significantly more reliable rather than standard HDD drives.

SSDs come with an typical failure rate of 0.5%.

Image

For an HDD drive to operate, it should spin a couple of metallic hard disks at over 7200 rpm, holding them magnetically stabilized in the air. They have a number of moving elements, motors, magnets as well as other gadgets packed in a small space. So it’s obvious why the regular rate of failing of any HDD drive ranges somewhere between 2% and 5%.

4. Energy Conservation

Image

SSD drives function nearly soundlessly; they don’t make excessive heat; they don’t mandate extra cooling down options as well as consume far less energy.

Trials have indicated that the common electricity consumption of an SSD drive is between 2 and 5 watts.

Image

From the moment they have been built, HDDs have always been quite energy–greedy products. When you have a hosting server with plenty of HDD drives, this will increase the month to month electricity bill.

Normally, HDDs use up between 6 and 15 watts.

5. CPU Power

Image

The swifter the file accessibility rate is, the swifter the data file requests will be delt with. Because of this the CPU do not need to reserve allocations waiting for the SSD to respond back.

The regular I/O delay for SSD drives is actually 1%.

Image

Compared with SSDs, HDDs enable reduced file accessibility speeds. The CPU is going to lose time waiting for the HDD to return the inquired data, reserving its resources in the meantime.

The average I/O wait for HDD drives is about 7%.

6.Input/Output Request Times

Image

The vast majority of el-wu’s brand–new machines now use solely SSD drives. Each of our lab tests have demostrated that by using an SSD, the common service time for an I/O request whilst operating a backup stays below 20 ms.

Image

Sticking with the same server, but this time built with HDDs, the outcome were very different. The standard service time for an I/O query changed somewhere between 400 and 500 ms.

7. Backup Rates

Image

Speaking about back–ups and SSDs – we’ve witnessed an effective advancement in the back–up rate since we switched to SSDs. Currently, a normal hosting server back up will take simply 6 hours.

Image

We used HDDs exclusively for lots of years and we have decent understanding of just how an HDD performs. Backing up a server furnished with HDD drives can take around 20 to 24 hours.
