Was ist haltbarer HDD oder SSD?

ByBurkeUndCo February 20, 2024February 15, 2025

Dass SSD (ohne mechanische Bewegung) deutlich schneller sind als HDD ist klar; aber was ist haltbarer?

Früher hies es, dass die Anzahl der Schreibzyklen von SSD-Speicherzellen begrenzt ist. Heute werden SSD auch als Boot-Platte, auf der häufig Schreibzyklen (durch das Betriebssystem) stattfinden, eingesetzt.

Muss man deshalb bei SSD mit einem früheren Ausfall rechnen als bei HDD?

Hi , Ich habe mir eine externe Festplatte für die ps4 gekauft.Habe anschließend darauf meine games rauf geladen.Jetzt vor paar Tagen habe die mal zum ausprobieren an meinem PC angeschlossen und sie initialisiert uns alles eingestellt.Danach habe ich sie wieder abgemacht und an der ps4 angeschlossen und alles war weg.Da stand das ich alles wieder…

Xbox 360 HDD in Laptop möglich?

BykingJesko November 12, 2023February 16, 2025

Servus, ich habe einen Älteren ASUS Laptop bei dem wahrscheinlich die HDD kaputt ist, da ich noch eine Xbox 360 rumstehen habe, und beide Geräte einen SATA Anschluss haben, und ich bevor ich eine SSD kaufe wissen möchte, obs wirklich an der HDD liegt, habe ich mir überlegt die Xbox HDD zu formatieren und die…

Warum fallen beim test immer markenprodukte durch?

Byklassik1989 November 23, 2024February 24, 2025

Egal ob Lebensmittel, Kosmetik etc im test heißt es immer ” die Marken fallen weg”. Bei handcreme ist die Marke aveo sehr gut bei Müller zum Beispiel

In the end, no one really fits your answers:

Chip-based data carriers need to be regularly supplied with power so that the data is maintained. This is not the problem with an internal SSD in a PC now. – and “regular” would mean here every 1 to 2 years.

ABER: For archive disks, this could be problematic if you forget.

In short: The magnetism of HDDs definitely lasts very long – and of course without power supply.
There can be no real long-term experience regarding SSDs – especially since the technology is developing rapidly.

Previously, the number of write cycles of SSD memory cells is limited.

This is still the case – and depending on the technology, the number of writing cycles is even decreasing.

Anyway:
Anyone who does not make backups must not complain about data loss – or hope for Empathie Pages Admins/Profis.

In general, the SMART values should always be kept in mind for all types of disks.

Do you have to expect a previous failure in SSD than in HDD?

In normal operation? Nope.
Of course, taking into account the specs of the respective data carrier.

Under the condition that it is also used regularly.

A SSD is unused in the cabinet. She’s broken. However, an HDD can be stored in the cabinet and it will probably work even in 10 years without problems.

But using a SSD is much more durable and reliable

Does this also apply to frequent writing cycles?

Here’s an explanation. Didn’t want to write everything yourself:

SSD disks (Solid-State Drives) use flash memory cells to store data, unlike conventional disks using rotating magnetic disks. While SSDs offer many advantages, such as faster reading and writing speeds, they are also susceptible to certain types of errors, especially if they are not used over a longer period of time. Here are some reasons why SSDs can break if they are not used:
Data retention and degradation: SSDs store data in flash memory cells that can be electrically deleted and re-described. Over time, the electrical charges in these cells can naturally decrease, which can lead to data loss if the SSD is not used for a longer period of time. This is called “data retention”, and some SSDs can lose data after a few months to years without power supply.
Wear leveling and block management: SSDs use Wear Leveling algorithms to ensure that write operations are distributed evenly to all memory cells to extend the service life of the SSD. If an SSD is not used for a long time, these algorithms may not work effectively, which may lead to uneven wear of the memory cells and ultimately to a possible failure.
Power failure and data corruption: SSDs require a constant power supply to operate their internal controllers and storage cells properly. If an SSD is not used over a longer period and the power supply is interrupted, internal data structures can be damaged, which can lead to data corruption and ultimately to a possible failure.
Condensation and environmental influences: If an SSD is stored in an environment with high humidity or extreme temperature fluctuations over a longer period of time, moisture can accumulate and lead to condensate formation, which can damage the internal components of the SSD.
In order to avoid these problems, it is recommended to use SSDs regularly and not leave them without power over a longer period. If SSDs have to be stored for a long time, it is advisable to store them in a dry and temperature controlled space and to activate them occasionally to ensure data integrity.

Absolutely. Ne HDD uses more and more of a rough word sooner or later.

A SSD does it rather well when it has to do regularly with writing and reading data.

Like I said. The SSD only harms this without being used.

Yeah, that’s just right. It was just improved. Here too, a brief explanation is as simple as we always text:

However, the technology has evolved over time, and modern SSDs use advanced NAND flash technologies such as 3D-NAND and TLC (Triple-Level-Cell) or even QLC (Quad-Level-Cell). These new technologies have significantly increased the number of possible writing and erasing cycles, resulting in improved durability and service life of the SSDs.
In addition, SSD manufacturers have implemented advanced Wear Leveling algorithms and error correction mechanisms to further extend the service life of SSDs and to minimize the impact of NAND Flash wear.
As a rule, modern SSDs are very durable and have a high number of writing and erasing cycles before they show signs of wear. Most users will hardly impair the life of their SSDs due to normal use and write activities. Modern SSDs can therefore be considered as reliable storage solutions designed for long-term use.

I’m not really up to date anymore, but:

In principle, the data are stored in an SSD by bringing electrons to a gate isolated from the remainder. And this insulation decreased at least with the previous SSD with the number of write cycles, so that the information could no longer be stored reliably.

Is this different today? new technology?

Or are the number of possible cycles so high that it is uncritical?
