SSHD as backup drive

[Matttt21]

Hey..

Im new on this forum, soo hello everyone.. ?

 

I planning on using an sshd as a backup drive. But is there a risk that would damaging the drive ??

 

Like.. I have to connect it to my laptop or pc in some other times to feed the power/electricity to the drive.

 

Im using it to backup my files, but i will use it whenever i needed, not like store it save in a long term.

I would get a regular drive unless you already have the SSHD.  Other than that I don't see a problem...or a real benefit if this is for backup.

I agree. Using the SSHD for a backup drive won't hurt it any but there would be no benefit to using an SSHD over an HDD. If you already have one, using it will be fine. If buying a drive for backups, i would recommend an HDD. In my experience, SSHDs are overrated. The one I had was actually a tad slower than an equivalent HDD.

No, but its a waste of money, doesn't make any sense.

 

SSHDs only are useful if you use them regularly for example as a Game Drive.

If you don't the SSD Cache on it is just there but doesn't do anything...

Go for a Normal Drive or SSD, an SSHD has no benefits when used as a backup. And no the is no risk damaging the drive.

For everyone.. Thank you for the answers.

 

I plan on buying it. Yeahh It is a waste of money just for backup, but in the near future when i buy a new laptop for work and games, i probably change that SSHD to my internal laptop storage and add a SSD for the laptop windows drive.

 

Is possible right ??

If you get a laptop that can fit two hard drives in whatever format you're choosing, yes.  Even so, a mechanical drive would be cheaper for storage/backup.  You could get a 7200RPM drive if you think you might use it for more than backup in the future.  SSD for windows/programs.  SSHD just isn't worth it overall unless you don't want to shell out for a full SSD for OS/programs.

Possible? Yes. worth doing? Nope. An SSHD will improve loading speeds somewhat, maybe, only if you access the same files repeatedly, something you are not likely to do with a data drive. If speed for a laptop data drive is important, forget the SSHD and just get either a 7200 rpm HDD or a large SSD. If battery life is important, then get a 5400 rpm HDD or a large SSD.

So.. SSHD is best to use as a prime drive, just like SSD. Okay.. You convience me.

 

Oh yeah.. Speaking of rpm, which is save or reliable or easy to repair between 7200 and 5400 hard drive 

??

Because i once had a seagate expansion drive and got a light hit to it and didn't show on my laptop, so i went to repair it. The repair guy told me that my drive is hard to repair due to the speed or other factor. Is possible to repair but my data might be broke or corrupt when it's recovered.

Sigh! You aren't paying attention. Just forget about buing an SSHD, period! Just because you can do something doesn't mean you should. You will NOT gain any benefit from using an SSHD.

 

You don't "repair" HDDs so rpm has nothing to do with it. The only difference between rpm is the slower the rpm, the slower the read and writes to the drive and the less power they draw. If they break, you will probably lose your data. Sometimes, a professional can recover data from a broken drive but that usually costs thousands of dollars. It's safer and cheaper to just keep a couple of backups of all your data.

[Matttt21]

Sorry..

Okay you change my mind on how SSHD do and the benefit of it. Now i just buy HD.

 

And yeahh i should also buy some extra drive for the long term backup just to make sure if another harddrive broke again i have the safer one with all my previous files.

 

Overall thanks Lady Fitzgerald for the advice.

SSDs and SSHDs are really unsafe, even with a secure delete (replacing all the bits with zero) you cannot be sure all the data has been deleted. I would go with a harddrive and use full disk AES-XTS-PLAIN64 encryption.

That is totally absurd and wrong. A secure erase will delete all data as effectively as replacing all bits with 0s; it sends a voltage spike to all the cells that reduces them to an empty state. Data is completely gone. Since no actual writing is involved, the reduction in write life is considerably less than wiping by repeatedly overwriting 0s and 1s.

 

All drives, SSDs and HDDs, are subject to sudden, irrecoverable failure. As long as one maintains proper backups, there is no reason (other than, maybe, cost) to not enjoy the advantages of SSDs.

 

Whether to encrypt an entire drive, or even just a folder or few, depends on each individual use case.

Do a quick search and you can find out about deletion of data on SSDs, most of the time you can be sure every bit was flipped to zero but not all the time. The only way to be safe with a SSD is full disk encryption but I still rather go with a regular HDD

Jesus OP is wondering about a backup drive. Not about how easily you can destroy data when it's time to retire. Just smash it with a sledgehammer if you're so concerned or donate the SSD to the local gun range and have at it.

[TechyBen]

Even regular HDDs can reallocate sectors, and the old sectors/data can theoretically be recovered. However, it's sparse/few/fragmented/small files only... so it depends if every file on your PC hold your banking details and passwords, or if the 1 in a million risk of the password getting out is any worry or not.

 

SSDs work differently, but again, theoretically could mark a cell/chip as bad, data still recoverable to third party/physical access. For home/consumer use, there is like more chance of you winning the lottery than a thief stealing a facebook account or banking details of such a drive once erased.

 

It depends on what level of risk you wish to take (where as a drive with zero erasure used, is like a 50/50 chance the thief/new buyer gets data off the drive ).

 

The reason for going HDD for backup, is the same reason for going Tape for corporate backup. Cost. Backup needs sequential write (and read when recovering) only... it needs occasional access, but longevity. IRRC, an SSD is about the same as a HDD, but some HDDs can survive longer (providing seals hold and spindle grease does not dry out). But the HDD beats the SSD on cost, and why worry about file access times and OS boot time on a backup drive?

 

However, an SSD is harder to brick by dropping, as no moving parts... but an SSD is easier to brick in other ways I guess.
