SSD is the acronym in English of Solid State Drive ( Solid State Drive ) and is the future of data storage.
The traditional rotating hard drives are nearing the end of their journey.
The latter is a type of mechanical device that consists of a turntable that stores the data and uses an arm to read and write said data on the disk.
As they are mechanical devices, they have their limitations in terms of speed.
The disk speed is measured in IOPS ( Inputs Outputs Per Second, Outputs Per Second), which shows how fast the reading and writing of data on disk is.
With traditional hard drives such as SATA and SAS, the IOPS figures are approximately 80 IOPS for SATA and between 140 and 200 IOPS for SAS hard drives.
With SSDs, the IOPS can be between 4,600 and 75,000.
That’s a huge difference when it comes to speed, which means that your website will work really fast.
That’s because SSDs are 100% electronic devices. There are no moving parts, so they work at a really incredible speed.
In addition, consume an energy equivalent to 20% of that used by traditional hard drives and do not require much cooling, so your letter of presentation in the ecological level is also impressive.
They are also ultra reliable. Its average time between failures is about 2 million hours, compared to 1.2 million hours of SAS drives and 70,000 hours of SATA drives.
What are the drawbacks?
The only big downside is that SSDs are more expensive.
Web hosts usually have thousands of hard drives and will not change them overnight.
In addition, SSDs tend to have lower storage capacities than traditional disks: an average of between 300GB and 400GB, while SATA disks offer between 1TB and 3TB.
That means that the expensive space of the data center is no longer used with the same efficiency as with the old hard drives.
All these factors make the cost of the SSD hosting higher, but if you are looking for speed, then it will be an intelligent option, as we will see.
