RN424 + Crucial SSD 1TB Drives

Hello, a customer we recently acquired owns a RN424 which has been fitted with three Crucial 1TB SSD drives, model CT1000MX500SSD1(Z).

The NAS was set up in March this year by another company, with a RAID-5 volume. It was serving as iSCSI storage for production VHDs.

This week two of the disks have failed consecutively and, although a backup has been restored and the customer is working again, he wants to know if it is normal that two disks fail 9 months after setup.

 

My belief is that those are consumer-grade disks, and that they should not have been used for heavy duty inside a NAS Raid-5 volume.

Am I right, or are they are perfectly fine for this use?

 

I would appreciate if somebody could point me to a written reference regarding the adequacy or not.

Thanks!

      Thanks for answering!

      Yes, those disks have 5 years warranty, but it will take some time until they are replaced, and failures cause downtime for the customer.

      Also, two drives failing in a short timespan makes me wonder if the disks are to blame or rather the NAS.

      From the specs, alhough they are consumer grade they look quite good.

       

      Thanks again!

        How did they fail?  Are you seeing a wear-level warning? Or something else?
