Thanks for the breakdown, a great insight on your specific setup.Most modern SSDs should be rated for quite a lot of writes these days though. That said, its still beneficial to get all unecessary writes off them (such as Windows 2394082536 million services writing %TEMP% and c:\windows\systemtemp and d3dcache etc.... As well as your browsers. Thats why I run a Ramdrive and have everything possible moved to it (such as Chrome and Firefoxs temp folders (there are a LOT of them).
I have a samsung evo 840 which has been online for 49.000 hours and written 14.9 TB, its still in good health.
On the other hand, my Intel 250GB NVME went into read-only-mode (with a warning) last month, after being in daily use since 2016.
Which was lucky, since I just built a new computer when that one failed shortly after.
I also have an Intel SSD with 38.000 HOURS and 38TB written (according to smart) which had some issues in Windows on the old computer, but SMART says its in good health, according to Grok.
- ~5.5 TB host writes + 38 TB NAND writes on a 480 GB drive rated for roughly 80–200 TBW endurance (typical for MLC drives of this era) means it's used ~19–47% of its rated life (closer to the higher end if endurance was ~80 TBW).
- The drive is not new but still has significant life left unless other attributes show problems (e.g., reallocated sectors, uncorrectable errors, very low Media Wearout Indicator normalized value, or high program/erase fail counts).
- At 38 TB NAND written, if the normalized Media Wearout Indicator (often ID 233) is still above ~50–60 (out of 100), the drive is in decent shape.
- SandForce controllers (like SF-2281) are infamous for performance degradation over time if the drive fills up, TRIM isn't effective, or with heavy incompressible/random writes — write speeds could drop significantly (e.g., to 100–200 MB/s or worse in worst cases).
The Evo840 series has great controllers, so you can count on the higher range.
But 49khr runtime with just 14.9TB TBW on the Evo sounds so odd. Not in a bad way.
Well, there is still tape drive used today. Recently reaching 30TB. Some Nuclear powerplant in Europe used floppy disks recently for some security related applications, the odd shape, no modern usage and rarity made it easier to spot if someone tried to smuggle it into high security areas.Floppy Disk 2027....is the future I tell you
