Can I replace the NVMe with hard drive?

x509 · 09 May 2022

When I recently replaced a traditional SATA SSD with an NVMe drive, the performance improvement was noticeable. A lot of SSD and NVMe drives include software to migrate from the old to the new drive. And replacing a traditional HDD with an SSD drive gave me a dramatic performance improvement.

Anybody that tries to tell you something different is either a scam artist, as others have said, or else 20 years behind the times. Is this IT guy recommending Windows 95?

SSD tech today is much improved over what it was when it was first introduced.

I still use an 8 TB HDD to store my bulk files like videos, music and photos, and my iTunes library. I'm hoping that when it's time to upgrade my motherboard/CPU/RAM that I'll be able to afford an 8 TB NVMe or ordinary SSD drive.

Imagine a 100 TB Nvme4...

Imagine if the controller fails...

I love to have a lot of little HDDs With my files all over them.

And that does not include music and movies. If it crashes. it's just about time to build a new library.

I wonder whether an HDD is more reliable than an SSD providing that both are kept in a safe place.

Doubtful - anything with moving parts tends to seize up if not moved now and then.

I don't believe SSDs are good as a long term storage solution. But HDDs are able to keep their data for many years without being powered up. SSDs need to recharge.

These transistors don’t require power to hold their state, but they cannot go without a charge indefinitely. This is because the state is determined by how many electrons are injected into the NAND gate which makes it identifiable as a 1 or 0 by its voltage.

These Electrons “leak out” over time and require the SSD to be plugged in to regenerate or reinstate the charges over the gates.

If this isn’t done soon enough the voltage will change enough for the state of the transistor to be changed which corrupts the data.

If you take an SSD, record files on it, and sit it on a shelf, over time the data on the disk will slowly evaporate. Come back in five years and the disk may be unreadable and all the files corrupt.

An SSD is absolutely positively no-nonsense not an archival storage medium.

For critical data, I store it in onedrive as well as my backup nvme.

Of course many will argue cloud drives are not secure for long term, but my view is if onedrive is falling apart, we have much bigger issues with MS. This pre-supposes MS do not sell the onedrive business to a 3rd party.

I do not really care much about rest of data - if not critical, I seriously doubt I would come back after say five years to retrieve such data. Data hoarding is same as hooarding stuff in real life - only a small fraction ever sees the light of day.

Some of us aren't data hoarders, but our data are disorganized, and we're too lazy to put in the effort to purge useless data.

With the continuous improvement in capacity/price ratio of drives, it's less work to just keep stuff. :-|

I go nuts with young engineers at work (working for me) who do this, as organisation of data is crucial to efficient working.

Back in days of paper, I had piles of stuff in office, and Office Manageress told me to get rid of these piles. I said "fine, but I will take a photocopy of everything just in case". She gave up at that point LOL.

I tend to be quite organised on pc with all my important client stuff, but do admittedly have a "misc folder" which I clear out now and then, when IT starts complaining about my network data storage being over 500 MB (that is a joke limit these days).

A few years ago, I paid some money for a Eudora to Outlook mail convertor, and then archived all my email from like the dawn of time. This afternoon I had a reason to look at that archive. If I had the time, I would have deleted most of it but I didn't have that time. Fortunately I was a bit OCD about filing email into folders, so it was easy to find what I was looking for.

I guess someday my kids are going to have to sort all that out.
