Hello everyone,
I've been told that SSD's can make unsafe backup drives for many reasons that no one on the earth seems to have real evidence of except in rare circumstances. After some research I see that everyone tells a different story. I want an SSD as my backup drive plus another SSD as my main drive.
SSD#1-- 1TB Samsung EVO 850 PRO
(main drive, better SSD since it will have many writes/erases)
SSD#2-- 1TB Samsung EVO 840
(copy backup data over and will most likely never move it unless necessary)
(PLUG: I have a high-end surge protector and a 1300W multi-rail PSU hovering at ~788W so its efficiency should be 90% at both minimum and max computer loads).
I don't care about cost per gigabyte or anything being a waste of money. Time is money and SSD's save me time so they all pay for themselves.
I've heard the following:
1) SSD's can easily lose all stored memory during a power surge, making them unsafe as long-term backup solutions
---PROBLEM: I've read that SSD's after 2011 are MORE reliable after a huge power surge than an HDD when it comes to retaining memory from surge damage. Could someone explain for me? I would imagine that a power surge bad enough to wipe an SSD would also wipe an HDD. And if a surge powerful enough came in to wipe my drives in general, I'm sure pretty I'd be more worried about my CPU and GPU than my storage.
2) SSD memory on an aging drive could be totally lost during writing due to errors creeping in over time from long term use (write failures at the end of the drive's life).
---PROBLEM: Can't this happen to an HDD as well? Don't HDD's have on-going errors that are constantly happening and being corrected? Isn't that what makes HDD's so stinking slow most of the time and is the reason why most people use partitioning for error logging? Either way, both SSD's and HDD's use magnetism for writing data, so how is an SSD less reliable than an HDD in this regard? I've only ever heard of an SSD having errors at the end of its life, but HDD's have constant errors straight from the box...
3) SSD's can lose all data if not plugged into a power source periodically
---PROBLEM: I haven't read a single thing about this for any modern SSD. I have flash drives with data on them that are months and years old, and their flash technology is 10 years old. But does this have any merit?
4) SSD's are still largely untested since they have yet to be economical. Because they are rarely made in capacities over 750GB their reliability is somewhat unknown after 2-3 years. Larger capacities bring in the issue of needing a longer term storage solution since SSD's are finally becoming large enough to stop backing up files and can be used as main drives.
---I'm not sure about this at all. Why would a company offer 3 and 10 year warranties then?
This is what I've gleaned. I'd love so really solid facts...solid like diamonds. I have enough personal opinions already to fill a 100 page word document. I'd love some facts!
Thanks everyone!
