IOPS stands for Inputs Outputs Per Second. It is a common way of measuring the performance of hard drives such as SATA, SAS and SSD hard drives.

IOPS are concerned with determining how fast a hard drive can read data from and write data to a hard drive and can be used in both traditional physical ‘spinning’ hard drives as well as SSD Drives.

Generally IOPS are used to measure a range of performance scenarios such as:

  • Random Read IOPS
  • Random Write IOPS
  • Sequential Read IOPS
  • Sequential Write IOPS

The reason that IOPS looks at both Random and Sequential IOPS and Read and Write IOPS is because this takes into account real world situations. Data is rarely stored on the disk in such a way that it can be accessed in the most optimum manner.

SATA And SAS IOPS

Whilst there are exceptions, the following figures act as a good rule of thumb in terms of performance for traditional SATA and SAS hard drives:

7.2K SATA – +/- 80 IOPS

10K SAS – +/- 120-140 IOPS

15K SAS – +/- 180-200 IOPS

SSD IOPS

When it comes to SSD these tend to be manufactured depending on the need for faster read or faster write capabilities. However, if we take an Enterprise Datacentre SSD like the Intel DCS 3500 this has IOPS in the range of between 4,600 IOPS (Random Writes) to 75,000 IOPS (Random Reads).

Why Is IOPS Important?

Basically IOPS identifies how fast a hard drive operates. The faster the better for a number of reasons. Firstly, Google has stated that website loadspeed is a ranking factor – simply put, faster websites get better rankings.

Also, faster websites tend to sell more because users prefer a faster browsing experience.

Of course there are loads of ways to speed up a website but one of the fastest and cheapest is to switch to SSD Hosting.

What Type of Hard Drives Does Pickaweb Use?
