Interne Festplatte; Wieviel unterschied liegt zwischen den Umdrehungen 7.200 und 9.200?
Hallo,
ich werde mir wohl irgendwann eine neue interne Festplatte zulegen müssen.
Nun weiss ich dass es da so das eine oder andere gibt was zu beachten ist.
Cache –> was ist hier brauchbar?
64/32/16/8/4/2????
Umdrehungen
Soweit ich weiss hat eine durchschnittliche Festplatte 9.200 U/Min.
Nun habe ich bei Festplatten mit 1TB großem Spoeicher kaum welche gefunden die mit 9.200 drehen sondern immer nur welche mit 7.200. Macht es nun sehr viel aus?
also diese 2.000 Umdrehungen? Wieviel länger braucht der beim Zugriff?
Und welche Hersteller stellen besonders haltbare Festplatten her?
Gibt es etwas woran ich erkennen kann ob eine Festplatte die nächsten 10 Jahre überlebt?

I only know fes plates with 5400, 7200 and a few with 10,000 rpm. The access times are specified for each hard drive and do not necessarily depend on the U/min . The cache size affects the data throughput with which other variables in what ratio you would have to research yourself again.
For hard drives it is quite reliable, “who buys cheap, often buys”. I don’t know about 10 year warranty, but if there’s something like that, you have to look at the server area and especially for performance plates, so no storage plates.
In the final field, 5 years of warranty are the best known to me. A play for this warranty and price class would be the “black” series, for example by WD.
In principle, each manufacturer has very good quality and scrap-off plant in the assortment. The decisive factor is the price class and how much trust the manufacturers offer to their own product in the form of warranty period.
I’d rather look at the 7,200 as standard. Notebook hard drives and cheaper large plates typically turned with 5,400.
I’ve never had a 9,200. They will probably be even louder than the 7,200s, compared to the 5,400s.
For an internal system plate, however, I would definitely go to an SSD that doesn’t turn at all.
How can I experience how large the maximum hard disk size that I can mount?
This depends primarily on the operating system used, the partition scheme and the formatted file system. Windows 10 supports with GPT Schema and NTFS a maximum of 18 exabyte greetings partitions. However, such large hard drives are not available yet. The biggest thing I think is somewhere in the 20 Terabyte. Before Exa comes, Peta will come first.
I think technically you’re not going to be hitting hurdles… then it’s more expensive.
I’ve never seen 9200 hard drives. Most snd 5400 or 7200.
More rpm has faster access times, but is louder. If it turns 20% faster, access is 20% faster. But still takes over 5 ms of access.
But well, if you want speed, you should get a SSD. The biggest difference is random read if you need to read data scattered over the hard drive that takes forever. At the SSD, it’s as fast as if they were right behind each other.
Server hard disks hold longer, exos etc.
Put a SSD in, you’ll notice the difference.
I don’t need a ssd.
I’m the classic you know…
My question refers to classic hard drives
Okay, if that’s the case.
