Samsung 970 EVO NVMe SSD - Very high reads/writes

[NullPointer_]

I have a 250GB 970 EVO NVMe SSD as my boot drive in my desktop, that I installed late 2018. Over the last 6 months, using CrystalDiskInfo, I noticed that this drive has very high total reads and total writes. Even stranger is that the total writes is significantly greater than the total reads. It is beginning to concern me. I have a friend with the same drive (but in a larger capacity) who stats are much more reasonable. My thoughts are that this is probably due to the page file. The drive is used as a boot drive, and only stores the OS and my applications. I have run VMs in the past on this machine, but no longer do. Windows optimises this SSD once a week.

 

Firstly, is this normal or has anyone else experienced it? Is there a known cause and how can I prevent it? Any tips for looking at my SSD better?

Stats ~6 months ago:

Total reads - 9680GB

Total writes - 13620GB

 

Stats now:

Total reads - 13850GB

Total writes - 20370GB

 

PC specs:

Ryzen 5 2600X

16GB DDR4 3000MHz

Asus PRIME x470

GTX 970

250GB Samsung 970 EVO
1TB WD Blue

 

Let me know if anymore details are needed. Thanks in advance

The 250GB 970EVO has a 150TBW (TeraBytes Written rating) for warrantee support, so Samsung expects a statistically significant portion (>90%, I'd reckon) to make it at least that long. You're only at 20TBW, so even at a rate of 14TB/year, you've got close to another decade, at which point other wear items will probably kill it first. Samsung SSDs have some pretty impressive track records of going well beyond their TBW rating.

 

Windows is always reading/writing little logs and caches and whatnot in the background, especially now that the performance penalty for doing that with SSDs is basically nil. The SSD in my laptop has about 8TBW in 8 months (counting it's full drive burn in), so it's not too far off for a more heavily used machine (my laptop is just a web browser/research device).

Hi, thanks for your help. That is reassuring. I do use my Desktop alot for games and work, so I'd expect it to get battered but as you say, even with this amount of usage, I'll be going strong for a while. Thanks again.
