At the moment I have opted for an Appleraid0. Maybe less certified but it's up and running in less than a minute. 

I have TM backup running so I can bear with a failure and in less than 3 hours I'm ready again.]]></content:encoded>

                        <content:encoded><![CDATA[Now you are seeing the performance difference between two SSD drives.

A Certify process writes a pattern, then reads it back. It appears one of the SSD drives is much slower than the other.

One thing I have seen in industry news that some Samsung's lose up to 50% of their performance over time. Sometimes a Certify can refresh them, but this issue seems to affect larger capacity SSD drives. What I understand is around 5,000 power on hours is generally when this happens.

Regardless, it is a point that not all devices are the same. If these are both new, then perhaps you have enough data to complain and try to get a replacement.

Yes we highly recommend the certify on new disks and SSD devices. In your specific case, you may have discovered you have a defective SSD, on day 3. Imagine discovering this after 6 months? or after the SSD failed?

Disks have a initial failure rate, then a gradual failure curve over time. Certify cuts the initial failure incidents dramatically so it is totally worth it to certify disks.]]></content:encoded>

                        <content:encoded><![CDATA[Hi.

Today my akitio Thunder2 Quad Mini case has arrived.
Unmounted my old RAID0 volumes with 2 1tb Samsung EVO 850 ssd, I'm now certifying softraid lite (i need a RAID0 volumes).

One of the two show 39 (increasing) hours remaining. The other one 3 hours.

Why so much difference? And really I have to let my macpro powered for about two days?
