As of today my company changing policies regarding our company data backup plans!
I never believed that i would write this, but
this is true and I present my objective opinion about following issue:
You can’t trust SSD manufactures that your data will be stored in consistent and permanent
matter on your SSD!
Way to many times it did happen to me or my employee's, in 4 years this is already a 2nd time where my system SSD on desktop office pc did failed beyond recovery!
(SSD VENDOR DOESN'T MATTER, I used all famous vendors!!!)
Let’s look what a typical SSD offers:
This is obviousand what did happen to me is marked with red color.
The controller interface chip will eventually fail after certain and continuous write and read operations.
The NAND chips would not help if controller broken!!!
Good luck of figuring out how data stored in those chips!
Let's think about what is wrong about SSD sustainable operation usage: there certain amount of read and write operations before only
read operation physically available, then SSD should be automatically switched to read only mode allowing SSD user to access the data, which is stored in NAND memory.
Good that we at Orlovsky Consulting GbR invested good amount of capital for running physical backups on premises.
Now it’s reasonable to make rhetorical question: is SSD a huge step backwards in regards of storage and maintenance of data?
SOMEHOW I KNEW IT!
Since 2015 I use lots of non SSD disks, mostly HDD Sata which are running 24/7, they are almost never did fail me!!!!
How this possible you ask, we’ll have a look at HDD diagram:
As I marked with red lines, there only 2 possible breakage points with HDD: disk head or spinning disk.
I assume the HDD disk‘s which I bought were perfectly engineered for very long running lifetime and the
material tiredness did not happen, which is good and more then I and the HDD manufacturer actually planned for.
This is really great!
SOMEHOW I KNEW IT!
You probably say , yeah whatever, you have your backups , why to bother?
YES, I DO HAVE BACKUPS
AND NOW EVEN MORE THEN BEFORE!
What about running business, which impact it, did have on my company?
To recover a 1TB SSD drive it takes almost 10 hours!
Don’t believe me?
Have look at the picture from the recovery station.
It takes almost one day (10 hours) to recover 1TB SSD disk!
During this time, you can't do anything, if you not in office or have no other means to access the data!
At my company we value and follow GDPR, this means we can't simply put
client data in a public cloud, only one exception when a client gives a special written permission
and specify what type of data may be stored in the public cloud, but this happens mostly never.
I hope now you do understand that this is a big issue!
What is most worrying that already there a shortage of microchips!
