[SOLVED] OBS Replay buffer or local recording to save SSD lifespan

[danny009]

Which one should I use to avoid SSD writes? I do not know what replay buffer is but still did a gameplay with max memory 560MB 340sec and it did saved 318MB to my SSD. RAM buffer and replay buffer is the same thing? OBS also did saved two clips 5mins of same gameplay. OBS also took it's sweet time to actually finish saving into SSD, no idea if it's normal. Can anyone explain this a bit here so I can save some lifespan on my tiny bit SSD.

Thank you for your time

What size/make/model is your SSD?

What is the current TBW on it?

WD PC SN735 512GB, Health GOOD %97 TRIM monthly, Write Cache turned off (did 2 OS reinstalls from win11 to win10, reset this pc option. Plus games and video files, however I always used small quality option in OBS to this point)

Total Host Writes 14075 GB

Thanks

If this is your drive:
https://www.westerndigital.com/en-za/products/internal-drives/pc-sn730-ssd?sku=SDBQNTY-512G

TBW for the 512GB is 300 TBW.

You've used ~4%. As evidenced by the reported 97% lifespan.
You have decades left on this.

That TBW number is for the warranty...NOT when it will 'die' from too many write cycles.
Consumer level drive have been shown to last far far beyond that published TBW number.

I wouldn't stress too much about trying to limit it, and just use the drive as is.

You'll replace it for other reasons, long before it runs out of write cycles.

Yes I think that is the drive indicated on the official website you linked, only exception is mine sn735 variant, probably the same thing though. Thank you alot for detailed info you shared. I think I will use in OBS CBR 6500 bitrate 720p 30fps. Most people say to me they screw you for using 720p in 2024 but it is no real issue to me honestly what is the big deal playing everything in super duper settings. No need. Anyways thanks dude for the help.

People stress far too much about write cycles on their SSDs.

I seen people discount a particular drive because it has only a 600TBW rating, were others are 1200 or 1500.

That's like the warranty on a car, being 10 years and 2 million miles vs 10 years and 4 million miles.
In neither instance will you run out that mileage.
