AE Disc Cache on SSD

[Rocketbottle]

Hello

I have not yet found a clear answer to this technical question. Any wizards here to share their knowledge?

After suffering an SSD failure on my Mac, I started to wonder how safe it really is to constantly write and re-write a large disc cache on SSD - talking about heavy daily use?

Any technical knowledge if SSD will suffer from this?

Regards

Yes, they still suffer, but these days their durability is much better than it was even five years ago. If it's really a concern, you might want to err on the side of caution and at least get a more expensive dedicated "storage" SSD as they are used on database servers or even go so far as to create an SSD-based RAID. Everything else eludes your control, anyway. The crux of flash storage still is that a single damaged cell is more disastrous than a damaged sector on a magnetic platter drive. Even if there is hash information or even actual duplicate data it may remain irretrivable due to entire memory stacks being physically cut off electrically whereas on a magnetic drive you can reconstruct data realtively easily based on math even if there is no backup. In any case, there is only so much you can do. A new drive can fail in the first week and all the same sometimes 15 year old ones will not die even if they're long past their design lifespan.
