Wie lange hält ein SSD-Speicher, ohne zu nutzen?
Hallo Zusammen.
Wie lange hält eine Externe Festplatte ohne genutzt zu werden?, SSD Festplatten brauchen ja Strom um zu Speichern, HDD nutzen ja Magnete um zu speichern. (Soweit ich weiss) Aber wenn ich mir eine Externe SSD Festplatte kaufe wie die -> https://www.mediamarkt.ch/de/product/_sandisk-extreme-portable-v2-2018090.html
Wie lange wird sie die Daten sichern, bis es alles löscht?. Oder mache ich mir da zu viele Gedanken? Ich werde die als Backup einmal im Monat nutzen.

~8 years
You can’t say it exactly, it can go well for 15 years or be over after 6 years.
Band storage lasts +20 years and is still considered one of the safest storages.
Bands are such a story. As long as they are used – all right. It can be annoying if the next drive no longer accepts the old bands. Can be at the format or the adjustment of the reading heads.
We used to. But there was no problem because we were the old one. I think it would be possible to take a transitional period.
Nevertheless, they have long done theirs.
They are often used in universities and companies. They’re more up-to-date.
That’s not quite true. Let’s get the posts of MichaelSAL74 and me.
The mail has nothing to do with tapes? What do you mean?
You’re trying to tell people a mistake, even though they didn’t make a mistake. This is your fault, otherwise nothing is wrong here. What are you doing here anyway? People angry?
Tell you about your mistake. Depending on the storage type and quality you have between 4 months and a little over a year.
So, if you’re in the worst case with 3-4 months, you’re on the safe side. 8 years would be conceivable for an HDD.
Why, I wrote, “You can’t say it exactly,” so what do you want from me?
… separated from the PC in some cases not even 8 months!
Since m.2 NVMe SSDs are normally installed in these enclosures, which are designed for consumer purposes, storage of about 1 year is required.
More details about this in my blog of 2015, which is still valid: https://www.attingo.at/blog/risk-of-data loss- bei-ssds-without power supply/
That was so – cheaper storage chips keep 4-6 months through…
So the ct has made a long-term test and has also been confirmed by readers and is very clear indication of them: memory cards as well as SSD must be hung to a power source within a year period, otherwise data loss threatens
And from this: I wouldn’t trust any SSD to really relevant data. HDDs are much better and more durable
Hello Michael,
Absolutely correct answer with the annual deadline.
Because of durability in general: Since last week on heise News gave an article that SSDs actually longer hold as HDDs.
But: You’re right, you always have to keep important data on one second secure. Because no HDD or SSD or DVD lasts forever. 🙏
Yes SSDs keep longer and the downfall rate is somewhat lower. But the problem is the kind and meadow as these disks fail.
I am a data savior and can tell you from my experience that 95-98% of my customers have been warned months before a failure based on the SMART values. Only no one has observed the SMART values…
In SSDs, I didn’t have a single customer who could predict a failure based on the SMART values. SSDs fall to 99% due to firmware problems and these always occur suddenly and without warning.
Hello Gandalf
OK. The news has gone past me, of which: DaSi is always made on at least two or three data carriers and this is changing. Old wisdom, which nowadays likes to be overlooked and ignored.
So I’m still in operation with the HDDs in terms of long-term durability. From pure experience. When I look at how many SSDs and HDDS we had to exchange in recent years, the SSD of the losers is clear.
Absolutely right. However, if HDD had already lost the data because the corresponding sectors were only read and not described again. That was so after about 10 years.
At the moment I think the storage on CD/dvd etc. Is a bit more durable, but forever it won’t be.
Maybe print out again? But the amount of data doesn’t work anymore.
We drown in data.
Hello Norbert,
Simply install an additional 8 TB HDD in the server… 😂
I try to convey knowledge as universally as possible, but if you are interested in data recovery, my book would be the better approach. The videos are rather small excerpts…
OH Does not sound bad, but also after work
Question is: Will it be the Otto-Normalo?
If we have 999 TB full, we simply continue with Petabyte (PB)…. 😂
I’ve been getting this for more than 20 years. At the beginning the large plates were in the mb area, little later GB, we have the tb plates. Where is that going?
Yes – I’m working on a few videos in which I give a few insights into how the disks work and in which I can also show what’s going on and what you can do…
THAT is the problem: SSDs are falling out today without warning from yesterday. You can still keep an eye on the SMART values
Hello Bernd
Neija, we have a few more than 20PCs in the customer’s use and especially in corporate customers I would say that the default ratio is loose within five years at SSDs at over 50% in contrast to HDDs with clear 1%, if not even more under
Hello Michael,
Oh, really, you had more SSD failures? 😂
We haven’t had one yet… but we only have 20 PCs we manage here… that’s not really representative…
Best regards,
Berne
Definitely not the time periods you have as a user.
there have been a few years in the end.
No, that’s not true. They may last 20 years with an average writing performance but in extreme cases only a few months in the desk drawer!
This depends on the storage type for the SSD. Depending on the storage type and model, it can already occur 4-6 months to first bit errors.
Until the whole SSD is empty it definitely takes a few years but this is actually the wrong question. When a backup is done, you should not be interested in when all data is gone, but when it starts that individual files are damaged.
Depending on the storage type in the worst case, this is the case after a few months. The decay then proceeds slowly and after a few further months many files will be corrupted and again a few months later most files will be corrupted.
It is enough for many file formats when a few bytes have been changed in the wrong place so that the file becomes unusable and can no longer be opened.
Depending on the degree of damage, this can be repaired again with special tools such as those of datanumen.
So if you use the SSD monthly, that’s not a topic, but as a long-term memory, I’d rather put on HDDs. However, the process is much slower and the first problems occur only after years.
100 years.
Complete humbug!
Right, there are 10,000 years ± couple zeros 😉
Sorry, I didn’t see it completely…
My comment was of course ironic 😀
No, if you’re in luck, you’re 100 days.
Have you ever put a fully charged phone in the drawer and then switched on after 3 or 4 months? Was the battery still full?
The same happens in an SSD only that you have billions of batteries in which the individual bits are stored.
Depending on storage technology and quality, you have 4-6 months or about a year to start data errors.
