one thing to remember, SSD have finite write cycles, eventually the memory cells fail and there aren't any spares left to fill the void. Thats why SSD warranties contain TBW ratings, Terrabytes Written.

HDD on the other hand will not degrade in the same manner, but bearings will fail, heads will crash, controllers will malfunction, etc. there is no perfection, and there is no perfect medium, it all depends on what you want to do with your data and for how long.

 

Some libraries and museums here store everything on Blu-rays. They make copies of them every 5 years.

Microsoft: Quartz glass as the storage medium of the future. https://unlocked.microsoft.com/sealed-in-glass/
Each quartz glass plate could store up to 3,500 films and last for up to 100,000 years. According to the team, large data centers for data storage would then become unnecessary.

 

I have a couple of BluRay burners. Several years ago I did some extensive test (it took me months). Conclusion: This is a very unreliable medium unless I use certain TDK discs imported from Japan (and quite expensive). With most discs from other manufacturers (= all brands normally available on shelves), if I burn them with one burner, another one will not read them even on the same day.

 

I only use Verbatim Blu-Ray blanks and a very good Blu Ray burner from LG. You should also install reliable software.

 

Back then I found some website with measurements showing error rate of various brands. Many advanced users recommended that TDK line of BR media. Initially, I wanted to avoid the hassle and additional costs, but - as I said - I did extensive tests. TDK never failed me, all other brands crapped out at some point. Personally - having nothing but extremely bad experience with Verbatim (their infamous SuperAZO CDR's and DVDR's, and later their BR's), I would not touch anything from this company even with a long pole.

 

I've learnt just a couple of rules working in IT, which I also follow personally.

The "3-2-1" principle: three copies of the data, on two different mediums, one of them off-site.
The "test" principle: if a recovery of data from backup is not tested regularly, it isn't backup at all.

For non-critical data of course this means sweet FA, use anything that's convenient. Personally my data "in use" is on SSDs of various kinds, it's then backed up locally to a HDD RAID array and an external HDD drive. Some stuff is burned to optical media for long term archival and stashed out of my place (and studio stuff is then kept at my place). I do also use cloud storage (encrypted, of course) for some stuff that needs to be available in case a disaster strikes.

The nerd in me would like a tape archiver, but that would be just for show. Tape robots are great fun and cool devices, when they work and are tested regularly, that is.

 

is it right that if u not useing a ssd for rround a year it can lose data cause its eerrm hot electronic magnetic what do i know written and not kind of analog on hdd disk...?!
whats your experience ?

 

Despite having BluRay burners (and many BR discs in my archive), I still use mostly DVD+R's. They are much more reliable.

I always burn 3 copies of the same data and verify every single copy on two different readers (different from the burner). It takes ages, but I sleep well.

 

Those who house their stuff on glass shouldn't get stoned.

 

Coming back to the topic: I have a couple of spare laptops, which have exactly same programs and configurations as my main computer - just in case. I turn them on for at least half an hour every month, so that the SSD's don't lose data.

 

no, you are brainwashed to beleive that. Newer technology is usually just newer til it proves itself. I have bins full of bad tech, that was supposed to be the absolute shit when it came out.

 

I usually image my laptop drives (hdd) to an external hdd for backups. before I convert or restore the image to SSD. then I have a functioning o/s image on hdd, and the original hdd as backups, of course the SSD acquires more data as its used, so a new, or additional (just the changes) backup must be made periodically.

I like Macrium Reflect, have been using it for at least a decade. no problems. (backup software)

 

that made my LCD crack...
