In my opinion you are only partially correct. if the RAID controller is in the raid, then that raid can be moved from computer to computer. If the raid is set up as redundant or backup then the drive can be moved to another computer and read. This would be a raid 1. Each disc is a mirror of the first one in a raid 1.this is done but writing to all disk at the same time with the same data.

In a RAID 0 the data is split up between all the disks and is used for faster reads and wrights, no mirroring is done. If one drive fails you lose some of your data. but if you have a raid array of four drives that equals say one terabyte you can back that raid up to another drive with software, then you haven't read for fast read write and a backup.

As far as backing up goes you're correct. When you backup or copy a disc to another one you copy the viruses and everything, thus the need for continuous virus protection on the system.

At least that's the way I understand it.

Begging your pardon, but your "opinion" is confused or lacking in awareness. Do some damned research in the Internet, will you?

1. A RAID array is setup by a controller, either in hardware (on the motherboard) or a software controller. A RAID drive could be read by an IDENTICAL controller on another computer. The controller is what formats the drives in a RAID array, ANY RAID array. Whether it is RAID 0, 1, 2, 3, whatever. Most often the drives are a PROPRIETARY format of that RAID controller, and ARE JUST NOT READABLE BY A DIFFERENT CONTROLLER.

2. What do you mean "If the RAID is set up as redundant or backup"? ALL RAID IS REDUNDANT. That's what the "R" stands for. Do you know what that means?
It means that multiple drives are being used to hold the data, in different ways on different RAID methods, with all of them appearing as one drive to the computer operating system.
If one drive fails in a RAID array, it can be replaced, and the controller reconstructs the drive to take its place in the array.

The drives in all RAIDS except 1 are not identical. No single drive contains all the data. Mirroring (RAID 1) makes all the drives identical, with all the data on each one.
But these identical mirrors should not be thought of as "backups" in the sense that they cannot be individually read out of the array they were created in.

On that note, I am done banging my head against the wall with folks who don't understand and don't want to. "Opinions" are irrelevant. We are talking about how it all FUNCTIONS, not what you WANT it to be.

Over and out!

Are you thinking server raid, where the controller is in the computer. If that's the case, then the raid is harder to move, the next computer needs the same controller or move the controller also.......

A raid 0 has the data split on the drives. Not a copy like raid 1. Raid 0 is for speeder operation usually, And when one fails, you have lost the unit, and is not redundant.

Now, what I said, different from you, was some times you can move a raid. They are more controllers than one in the computer/server. There's a raid enclosure with the controller built in. It also has software to load on the PC/server. So it is easier to move, just need the software.

With a RAID enclosure you put your hard drives in it, but it has a RAID controller built in (usually a hardware controller). So when you connect to a RAID controller you will just see that single RAID 5 or RAID 6. There's always some software involved as well. Common types of these enclosures include Thunderbolt RAID systems like a G-RAID or a Promise 8-Bay Thunderbolt RAID.

That's that I've read, otherwise, we said pretty much the same thing.

I saw some sales this week on really small Sandisk large capacity SSD's. Seems like the 500 Gb version was $129? Then the bigger ones were more but in any case not $7 or anywhere close.

I've heard of 1 TB on a flash drive but not two. They were on Amazon, none of them had very good reviews. The biggest problem was booting up.

Good luck with them.


"Booting up?" Really? Do you mean "found"or "mounted" by computer?

A bit pricey but 1 to 2 TB sticks are available.

Ok, testing done, I'm out of here with these things. Earlier I had tried to download 811gb. to see if it would hold it. The needle was hardly moving and said it was downloading 5.26 mb per sec. At that rate it would have taken 9+ days to move the materials! I usually back up a full TB hard drive in less than 24 hours. I cancelled that download and wanted to see what it would do with a single file in which I had around 54 gb. of photos. I would have expected around 30 min. but it said it would take over 4 hours! I don't care how much capacity these sticks have, they are s_l_o_w! I hope I paid by Pay Pal because I'm going to try to get a refund on these.

The problem with these high capacity sticks is HEAT generated during large file transfer. When you try to transfer a huge number of files - make that huge number of large file size files, the stick can get very HOT. This affects the performance of the transfer and sometimes may cause failure of the memory stick that has gotten too hot.

Enough of high temperature operation of these memory sticks may cause failure. I do not use these sticks for reliable archival of files. I'm surprised these companies haven't figured out a way to put heat sinks in the sticks to keep the operational temperature down to safe levels.

Do not be fooled by the physical size.
A normal "flash drive" is quite small, so they could fit 2TB into it.

I've had one of these since Nov. 2019. So far, I've got 30gb stored on it, and all files are retrievable. Far from 2tb, but for $10, I'm not complaining. Yes, it is slow transferring information to it. But again, $10. . .

So what's the difference? Short-time backup, long-term backup (archiving), it's still a backup.



Backup used to recover quickly. Archive is, technically, kept forever.
Used if any and all backups fail, or if one needs something from ten years ago.
I have no "archive" as none of the backups are older than three months.
An archive (usually never used) is essentially a backup for the backup.

Short-term, long-term, are relative and semantical.
If you never use a backup, it's long-term by default.

Primary backup - first used, usually local
Secondary backup - used when first fails, may be on-site, different physical location.
Tertiary backup - used if the secondary fails, usually off-site.( ie. cloud storage)
(Any additional backups are being paranoid.)
Archive - kept forever (or a VERY long time), virtually never used.

Operating system boot, drives mount.

I won't. I have three locations, that's it.

I saw the earlier post as well and did the same research you have. My interpretation may be simplistic, but 'thumb' refers to the form factor and 'flash' the technology.

Did anyone else see the ad and purchase the 2 TB thumb drive that was advertised recently? I bought these -- these were advertised buy one, get one free. I couldn't believe a 2 TB thumb drive! So they came in the mail yesterday -- two of them for 39.95. I plugged one in to see if it even booted up, and to my surprise it did. Now with almost 4 TB of storage space I can back up virtually all my photos on a drive that doesn't have a spinning disc and won't be apt to crash. If they are still available I may order two more!

You've been scammed.

I purchase 3 of them for x-mas gifts, I just watched a brief video on how easy it is to use. It is supposed to catagorize the photo erasing duplicates. It also stores and recognizes if you input the same photo again. It is called the photo stick 2.0. I will let you all know what I think when I get the guts to try it!
