The latest report from Blackblaze, a provider of cloud storage, explained why SSD was more reliable than a hard drive. The company, which routinely studies the failure rate of the storage units used, has noticed very interesting patterns throughout the last quarter of the year. On the one hand, the failures of its hard disks have gone to more, and on the other, the HDD of greater size, of between 8 and 14 TB, are more prone to spoil. What is the first conclusion you draw? Indeed, it is best to divide our data and files between several smaller disks. The second conclusion, as you will see below, is that you should backup (or backup) your files periodically if you do not want scares.
But do not completely discard all high capacity hard drives either. Blackblaze, with its data, shows that the failure rate varies according to the brand:
In just one glance it is clear that Toshiba has two models of 4 and 5 TB that have not presented failures in this first quarter , but apparently “none have enough bays installed so that their data is relevant”. However, we must go back to the second quarter of 2016 to find faults in those hard drives. The interesting thing is the discs that are used in greater quantity. The one most used are those of Seagate: one of 12 TB with a failure rate of 2.22% and one of 4 TB with a 1.96% failure.
These are some of the higher failures of the set, but the highest one is carried by a 12 TB model of HGST with 2.6% failures. In reality it is a rather low failure rate, but it is still a lot of fewer units. In total the average of failures is of 1.56%, and that implies an increase in the rate of failures with respect to the fourth quarter of 2017. Apparently the trend is upward, but specifically the units of Seagate and HGST tend to fail less and less .
What does all this mean? On the one hand, do not forget to back up your files every so often and in various locations, especially those crucial data that you can not replicate, such as photos, work, the “math folder” … Depending on where you live , it is even advisable to make those backups in the cloud or physically locate the additional storage units in a place other than the computer, in case there is a flood or fire close to home (catastrophic sounds, but these variables must be taken into account ).
