[SOLVED] What is the best SSD for using in a system doing block chain work with RAID?

[jlandi]

Hello all,

I am looking working on a sensor monitoring server that is using block chain as part of the system. Bit of an oddity I find myself in because I have not used blockchain in any form with SSD or RAID environments.

I bring that up because I will be doing a lot of writing/reading from the hard drives and I can't use spool hard drives in this situation.

Right now, I am looking at using the Intel D3-S4510 Series SSD SSDSC2KB as my storage device in a RADI 10 setup.
My motherboard is a SuperMicro X11SCA-F and the RADI will be hardware level.

From my calculations these bad boys would take over 10 years to fail in a non-stop writing/reading situation, but I am only an amateur in these areas.

Thank you in advance!

I would not count on any drive(s) lasting 10 years.

Two immediate thoughts:

1) unless I am missing something RAID is not necessary. Just adds complications.

2) a SSD would be used just if it were a HDD. Just simpler, faster, cooler, quieter, less power consumption.

If failure is a concern, that can be mediated with a good backup and recovery plan.

There may be other thoughts and comments posted accordingly.

What type RAID array, and why?

As far as failure? You should always operate on the concept that any storage device will fail in the next 0.25 sec, and plan accordingly.

Hey @USAFRet! I think you replied to my questions way back when choosing the array!

To answer your questions @Ralston18 and @USAFRet, the sensor server is being put into a spot whereas I cannot easily access it (https://forums.tomshardware.com/threads/using-ssd-slc-storage-with-raid-10.3558595/#post-21486089 ). The reason I was going with RAID is to ensure continuity and to try and get 10 years out of the single unit. Either way, I am planning on having a cold spare installed with the sensor server encase the unit goes belly up regardless.

I heard that the RAID and Blockchain can cause excessive wear on the SSDs; however, I am not sure if that is a myth because all the research I have read online never brings it up.

And you've not specified the actual write cycle rate.
How much will be written on a daily basis?

If it is rarely written to, then you may well get a decade out of it (no guarantees, though)

If you're writing 200GB per day, RAID will not save you.

@USAFRet When I monitored the system last time the majority of the work for the system is occurring in the ECC RAM and not the HD.

I am not 100% sure of the writing and would have to go back to the Cockpit logs to verify. Sounds like (from a hand wave perspective) we are good.

Thank you!
