Hi Marrk - do you have a point to make?This drive was recommended in this thread.
I like this very much. Smaller is better.

In total agreement, the size of these SSDs have wonderfully miniaturized and now take up little space! Dave@RadDave My point is that, so far, I am very impressed with the size, speed and build quality of the drive. My post was intended to follow up on @Randy B. Singer's recommendation in the other thread. I would also recommend this drive to anyone who is looking for one.
excellent advice RandyI just want to point out that an inexpensive external Samsung SSD isn't a panacea. To my knowledge, not a single Samsung SSD includes any over-provisioning whatsoever. This is partially how they keep costs down. What does this mean? It means that while a brand new Samsung external SSD is inexpensive, and fast, it will slow down earlier in its life than many other external SSD's, and its life will be over sooner than with many other SSD's.

So, while Samsung external SSD's seem extremely attractive, you should know that you are sacrificing performance and reliability on the tail end of the device's life in exchange. You should know this going in.
Hi Randy - thanks for the info and link on OP - looked at the article and googled some others - hard to find out what these SSD makers do with this feature, i.e. very secretive; but seems that the proportion of reading and/or writing to the device plus of course how often these events are being done will make a difference in the reliability and longevity of these drives.I just want to point out that an inexpensive external Samsung SSD isn't a panacea.

...are there brands of SSDs that are of higher quality NAND and use OP methods well that you are using and recommending?
Thanks Randy for the info and links - that spreadsheet is indeed impressive, just too many to think about - and looking at your list on features of a SSD, not easy to figure out TRIM, SMART, and OP even despite reading several of Howard Oakley's articles.I recommend the Samsung SSD's because they perform well (at least for a good while) and they are in a price range that users are comfortable with.
It's possible to get yourself an SSD that's many times faster (assuming that you have a recent Mac to support it), and wildly more reliable. But you are going to pay for it. When I've recommended such external SSD's in the past, folks got mad at me because of the prices..............................
No SSD is going to give you everything that you might want. Ideally you would like:
- a good amount of DRAM
- a significant amount of over-provisioning
- support for Apple's TRIM
- support for SMART
- support for USB 4 or, even better, Thunderbolt 3 or 4
- SLC (single-layer cell) NAND memory
- positive cooling to avoid thermal throttling
....too many to think about - and looking at your list on features of a SSD, not easy to figure out TRIM, SMART, and OP...

Thanks Randy - looked on Amazon for '40 Gbps M.2 NVMe SSD Enclosures' and there are a slew of choices! Not sure all will handle size-wise the Samsung 990 Pro 1 TB you suggested above? Question on a fan - seems that half of these choices have a fan and the others not - my assumption is that a fan would be most useful if the SSD was being used for super fast reads-writes, like gaming or or viewing 4K/8K action films, and probably not necessary for routine backups (which would be my purpose) - might just pick a combo to see what it can do?

Don't. Yes, SSDs are preferable for many reasons, but unlike HDDs which USUALLY exhibit warning signs before failure giving you a chance to copy your data elsewhere, an SSD can fail without any warning whatever; of course this is not common, but for that reason I'm not ready to abandon all my HDDs just yet.Of course, all this is cloned and backed up to hard driives. I'd love to have everything on SSDs and one day, after I win the lottery (yeah right !!) I will![]()
Well, the price of SSDs has come down so much in recent years, esp. in the 1 TB range (my needs) that they are much more price competitive w/ HDDs (of course, still cheaper for the same capacity). However, when I upgraded my computers to Apple silicon on the APFS, I also switched over to all SSDs for my backups - on the SSDs those backups to TM & CCC x 2 for both, i.e. 4 SSDs for each of my Mx computers are so fast that I can almost just sit there to wait for a disk swap. Now there are concerns about 'how much' to fill the SSDs (seems less that w/ HDDs) and the other issues brought up in this thread - BUT I now have no external HDDs in the house and am not looking back.

It's also important to install the TRIM app, which evens out the map of SSD usage, rather than finding that some sectors get overused and wearing out. (I expect you already know that deleting files from an SSD doesn't delete all traces of the files, especially where changes have been made to them? That's why Apple discontinued the Secure Empty Trash option from El Capitan).That's why it's important to only purchase an external SSD that supports SMART status, or, even better, just get DriveDX, which does very advanced reporting and failure prediction:
