What is the advantage of an enterprise SSD versus a consumer SSD?

[Cromulent]

I'm starting to think about my new build (not actually going to build it for a year or so but I need to start thinking about components so I can save up for them) and was wondering about whether I should get consumer grade SSDs or enterprise SSDs.

I'm thinking of getting 2 NVMe PCI-E SSDs (one for Windows and one for Linux) and was wondering what the real difference is between the enterprise SSDs and consumer SSDs? If I wanted better reliability (even at the cost of a little bit of performance) would I be better off with the enterprise PCI-E SSD?

Consumer SSDs are optimised for small disk queue depths and Enterprise SSDs are optimised for large disk queue depths (things like databases, mail servers). Have seen a few benchmarks where consumer SSDs outperform enterprise ones at small queue depths (the typical usage you will give it in a PC). Sort of like single-threaded performance vs multi-threaded.

Ah, that makes sense. Thanks.

I forget the term but they also have higher number ofspare sectors to replace failed ones.

Oh, over provision.

So in general they last longer then? Hmm. I was thinking about putting 4 SSDs into a RAID 10 array. Sounds like enterprise drives might be what I am after all.
