Which hard drive should you choose?

Question

linux

Hello everybody! Recommend a hard drive worth up to 15 thousand rubles and a volume of at least 4 TB !!! The disk must:

• Be reliable. Important data will be stored important data (mainly video and iso images). I know about shingles (smr), they say they are very unreliable.
  
  

• More or less fast. The speed is not SSD's, but not like disks in the early 2000s either. Something average.
  

• Don't get warm. Overheating is a common problem for me. The laptop is overheating, then the computer. And my old hard drive was very hot when reading from it. It didn't get very hot while recording.
  
  

• Stable work 24/7. Will work around the clock. At night, it's mostly not very busy. The heaviest load will be in the evening and during the day. At this time, many large data will be written at the same time and different files will be read at the same time.
  
  

As you understand, the disk will be used 24/7. At times, there will be a high load on him. Most of the time it's a record.

I once had a hard drive, it also worked as described above. For some reason, I took an external one instead of the usual 3.5 inch one. He worked for me for 4 months in this mode, after which he "died in agony." The last month was warming, rattling, the video was distorted. And SMART showed they say everything is fine. I thought I'd live another year and a half and buy a new one! There are no bad blocks.. In vain I thought so :( Somehow I managed to recover the information. I inserted it and it just wasn’t detected and cracked a lot. I launched the Victoria HDD scan, so almost everything is marked orange there. Everything was orange and red. I don’t know how, but when I inserted it identified the disk and I took all the flash drives that were in my house, and began to transfer information anywhere. And to a computer, and to laptops, and to all flash drives. I successfully transferred everything and threw the disk away. 2 TB of information was recovered.

So, you read the requirements for the disk. And I also have a couple of questions:

1. What file system to put on the disk so that it is reliable and fast

? did a simple drive work?

3. Tiled Recording Technology (SMR) - what is it? Which is more reliable and which is faster? CMR or SMR?


The disk will be used in Linux, so the file system can also be Linux.

PS I think to take wd red plus 6tb. What do you think?

I WOULD BE VERY GRATEFUL TO EVERYONE WHO ANSWERS!!

Answer 1

Be reliable. Important data will be stored important data (mainly video and iso images).

It is impossible to take and advise a reliable disk. An abstract disk cannot be reliable or not, but you can judge a specific disk at a specific point in time, and no more. Those. does he work today? Reliable. Tomorrow broke down - turned out to be unreliable. It is almost impossible to predict this based on any data or metrics. Therefore, to store important data, it has to use a backup, if the data is very important, then backup according to the 3-2-1 rule. If you need not only safety, but also the availability of data, it still makes sense to think about RAID.

I know about shingles (smr), they say they are very unreliable.

It's not unreliable, it's slow. Therefore, it is better not to stick it into RAID arrays, it can fly out due to brakes. For storage of cold data - purkua would not be pas.

More or less fast. The speed is not SSD's, but not like disks in the early 2000s either. Something average.

Railway speeds vary, but not to say that significantly. See CMR, 7200 rpm, you can compare by reviews, but there is no point in comparing turtles with turtles. First, if for storing videos and images, what for speed? Secondly, compared to SSD, they will all drain.

Don't get warm. Overheating is a common problem for me. The laptop is overheating, then the computer. And my old hard drive was very hot when reading from it. It didn't get very hot while recording.

Solve the problem of overheating, HDD has nothing to do with it. Arrange a normal airflow, buy a normal case.

Stable work 24/7. Will work around the clock.

For a disk, this is more good than bad.

At this time, many large data will be written at the same time and different files will be read at the same time.
As you understand, the disk will be used 24/7. At times, there will be a high load on him. Most of the time it's a record.

Consider using several different disks. Some for storing "important data" (large and cheap HDD), some for "simultaneously writing a lot of large data and reading different files at the same time" (fast SSD with good performance characteristics, depending on the amount of data and their nature).

1. What file system to put on the disk to be reliable and fast?
2. I am very infuriated by the constant sleep mode when no one accesses the disk! How to disable it? That even in idle time the disk worked?
3. Tiled Recording Technology (SMR) - what is it? Which is more reliable and which is faster? CMR or SMR?

1. EXT4
2. See power management in your OS. You also need to look at a specific disk model - for example, WD had a WDIDLE utility, you can google about it.
3. What is SMR, it is written in wiki, on Habré, and in hundreds of other places. Google hasn't been shut down yet.
CMR is faster, there is no point in comparing reliability in its pure form, in the CMR array it is more reliable, since the controller can throw out SMR due to brakes.
Remember the important thing: a disk is a consumable that can live for many years, or maybe a couple of minutes. Store information accordingly.

Answer 2

Before I answer: what was the poor drive doing that was overheating? I have 5 hard drives in my system and some of them are older than me.
Briefly about disks: for such tasks there are wd black, wd gold, wd purple.
Black is easier to find in any city. Specialized in working with large files and high speed.
There is an option from Toshiba on 4tb, the most common without markings. There are suspicions that the disk is eternal. For an acceptable price.
The Seagate Exos drive is just as good. The speed is more than acceptable, if the system is not littered and the price does not bite, in comparison with Western digital.
Briefly on the questions:
1. Either Btrfs, because it is specifically for Linux and its speeds, or Ext4, because it is time-tested.
2. You need to go to the control panel, power, select your power management scheme and go into changing it, set programmatically how long the computer will go to sleep, and also click for hardware settings, and you will see everything. I'm attaching a screenshot. You need to set a very large value (Put more zeros) and the word "never" will be set by itself after the apply button. I have this 10000000000000000000000000000000.

3. I won’t be clever here - I don’t understand the issue.

Answer 3

1 we can’t talk about any reliability in the context of one live, if we talk about reliability, you need to have three backup copies, in different independent places
2 all hard drives are about equally fast now they give out about 200 megabytes
3 read the wiki

Answer 4

Do not take WD RED!!! They are not reliable!!!
If it’s cheap in wd blue (yes, it is positioned as normal, but with a bunch of video surveillance installations it shows itself perfectly. And in terms of speed and survivability, unlike Red, they die like flies)
If it’s more expensive - wd black (I would advise it)
As for cooling - deal with it, the same black discs are reliable, but rather "warm".

Answer 5

take any deshman that mom keeps
at least with a guarantee of 3 years
FSE the rest - you don’t need to forge,
well, your system will boot faster = and all that
it, the system, works with RAM
