External SSD Back-up
Hi Folks
Tying again to ask for your expertise and advice.
It's about time that I back-up everything on my PC to an external drive. Knowing little about it, it seems that a SSD device with no moving parts is probably best. I am happy to tell my PC every week or so to carry out this back-up, so nothing too hard would help!
Could you please advise which SSD's you would recommend for efficiency and reliability. Oh, I think 1TB should be sufficient, and I am running on Windows 10. My son recommends Scandisk, so your thoughts would be appreciated.
Thanks!

If your data's really valuable then general policy is to have a least 2 backups and alternate them. So backup to Disk1 one week, to Disk2 the next and then Disk1 again on the third. That way if something bad happens during the backup process you don't end up copying garbage all over your only backup.
Are you wanting to back up your personal data(photos, emails, documents etc) so you could restore them to another machine or do you want to be able to rebuild the whole machine, apps and all, ie make a disk-image? That makes a difference as to how you tell your machine to do the backup.
It's also worth considering backing up to the 'cloud'. If only so you're ready to tell people who ask, why you wouldn't touch it with a bargepole.

Hi netstruggler
Thanks for your comments, and yes, I should have written SanDisk - my mistake!
The idea is just to save personal stuff such as 'photos, word documents, and emails. If I have these available, hopefully I could transfer the data to another machine. Good idea, by the way, to run 2 back-ups in alternate.
Thanks again.

and keep them in different places..............................
I’d also suggest that the alternating backups go to different types of media , eg SSD and spinning platters. Also once a year or so, take a third backup and store it in a different location.
I've been making a collection of redundant hard/SS Drives to re-format and sell on. But seeing how much prices have fallen it seems hardly worthwhile.
Shall certainly use one or two for belt-and-braces additional backups.
Amazing prices.

Can I ask why? Do you think that every SSD (for example) is suddenly going to fail?

Been caught out like that with large spinning rust RAID5 arrays; if you buy 30 discs at the same time the tolerances are such that when they start to fail the second one to fail is within the rebuild time from when the first one went.
In the OP's case I'd just sign up with Backblaze and not worry about it.
thanks - Not something I'd thought of! But then I'm a cheap-skate and only buy one at a time..................
SSD's have an actual limited lifetime, based upon the number of times the SSD is written to. Its obviously varies by usage amounts but it if fixed and there is no recovery from it.
I would never have a backup with such an obvious flaw/limitation if my data was important to me.
The limit is why so many high end lightweight laptops die, and cannot be repaired, nor data recovered. Any Macbook Pro laptops after build A1708 are on board SSD chips so replacement of an SSD is basically impossible - it means a new motherboard, so nearly the price of a new laptop. Pretty much any othermanufacturer has the exact same problem.

Even the best branded media under optimal storage conditions will not last longer than a couple of years. At best, burned CDs last 10 years, while DVDs only last three years. Under real-life conditions, which are usually far off from the optimal, you can expect maybe a couple of years for CDs and less than a year for burned DVDs. The main alternative to CD backups, while a little more expensive, is external hard disk backup.
Most IT equipment functions properly for anywhere from five to ten years. However, the typical lifespan of an external hard disk drive (HDD) is only about three to five years. More expensive solid state drives (SSDs) that use flash memory instead of spinning discs generally last ten years or more.
The nice people over at the aforementioned Backblaze have some data on SSD and spinning rust drives. The jury is still out on which is more reliable for their use case, but the failure rates overlap. Their operating regime is different to a home user's.
It seems that, in practice, wear life isn't what kills a modern SSD.
Their numbers though (average drive life of under 3 years) means you'd be expecting something like £60/year for a two drive backup, and there is a choice of backup providers at that price point.

This is an oft used argument.. Yes it's someone else's computer. But that computer is built to a higher quality than your home computer. And it's kept in nice solid racks in a data centre with air conditioning, clean power, backup generator and security guards on the door. Your data is actually distributed across lots of computers in different data centres, maybe even in different countries, so all that nice physical stuff isn't really necessary. And it's looked after by professionals with proper monitoring and fault prediction. And in some cases a $2bn R&D budget to make it better (or fiddle tax, depending on your cynicism) so you get continuous backup, point in time recovery etc.
All.of that is pretty pointless really because what really matters is....
What if that fails, or the company goes bust.
If the company goes bust or raises prices you just go elsewhere, or revert to DIY.
I've no idea if cloud is right for the OP but it is almost certainly more reliable than a pair of external hard drives.
old but still correct
I have IBM punch cards that still have the holes in them that I can read that are over 70 years old. If I could figure out how to do it the images on my website would only take 13,750,000 cards.
If I could figure out how to do it ...
I once dropped a large, un-numbered deck of cards. Never did that again!
PS Back on topic.
Another vote for Backblaze. The beauty of this system is that it runs automatically in the background, so backups are always up to date, unlike my local disk backups, which I typically run weekly.
Another feature of Backblaze is that I can access my files via the web, using any computer.
