ssd v 15k sas

[s3ds]

I use a CAD program with high I/O and have always used 15k SAS/SCSI drives
I believe SSD will be quicker but will the drives last ?
How long are SSD's lasting these days ?

Depends how much you expect to write to it. Just get a decent quality SSD, for example anything made by Intel designed for write-intensive workloads, including as far back as the DC S3710.

15k SAS is dead slow.

Bought my Samsung 830 back in 2012 (SMART reports 55210 hours of powered on time and 18.4TB written as of today) and it is still going, also it has been relegated to scratch disk usage since I bought a Samsung 850 Pro.

Stick with major brands, personally I like to steer clients towards Samsung EVO/Pro drives.
SATA or NVME is generally not that important, since most people do not frequently work with any files that are multiple GB each in size. Getting a bigger SATA drive is generally considered more useful than a smaller NVME one.
Samsung have in recent years reduced the warranty for their Pro drives from 10 years down to 5 years, but I would not be too concerned about that. By the time it fails you will likely have outgrown it already.

The only SSDs that have failed on me in recent years were DOAs that either did not function out of the box or caused boot issues within a day or two of being installed. Everything else is still working and do keep in mind that I have literally installed 100s of them in recent years.

SSDs last just fine and have for some time. If you want the best longevity there are "pro" drives that can take more writes than the consumer drives that use triple level flash to keep costs down.

OTOH, drive life is measured in how many times you can re-write the entire drive contents. If you buy a consumer drive you can probably get twice the capacity for the same price which with twice the drive size is twice the total data writes it can take.

If you go for a Samsung 860 Pro SATA drive, it is rated at 0.64 drive writes per day. So on a 1TB SSD you can write 640GB to it every day for 5 years and be within warranty.

I think I am pretty hard on drives with automated code building systems that generate and then compile a lot of output, and I went for a consumer drive. That only gets me a quarter of the endurance rating, so I can "only" write 160GB per day. But then if I had spent as much as a Pro drive, I could have a 2TB consumer drive and that would allow me 0.16x2TB=320GB per day.

If your budget can stretch to it, you could always get an Intel Optane SSD. The 900p is rated for 5.11 petabyte writes over it's lifetime!

I am struggling to find total writes on my drives
They are in raid 1 on a Highpoint controller
Smart
205 Total bytes written 445027328
3e00 Power on time (minutes) 1290922
POT Seems correct but the bytes written does not seem correct.

A magnitude more wear for a magnitude more money, I think I would rather have the extra available storage of a big traditional SSD.

With that total of writes you'll be fine with an ssd and all the little productivity gains you get from one add up, obviously you'll have a decent backup routine where it won't really matter if it fails after a few years and you can always use your current SAS drives as extra backup.

Yes I backup each night to another Raid 1 drive on the PC and that is backed up randomly to an offline drive
