Question Comparing SSD's

[GunsMadeAmericaFree]

I'm getting ready to build a new system, and I ended up buying a Silicon Power XD80 SSD for it. (1TB m.2)
I mostly picked this because of a glowing review from Guru3D.

It shows 2 million hours MTBF, and also shows "800 Terabytes Written", whereas I see a lot of other SSD's
that are only showing 200 or 300 Terabytes written.

Does this mean that the drive should handle this many Terabytes of data written during its lifetime,
before failing?

It's just the way to limit the warranty when drives are used heavily.

Most consumer users don't use that much R/W on a drive over 5 years but, a lot of companies changed their TBW / year values due to the Chia craze that toasted a bunch of drives due to the constant activity.

For me the performance is more important than the warranty as if it's going to die it typically will either be DOA or within a month or so if it's a defective product.

What do you plan using the drive for? If it's normal day to day stuff with maybe some gaming any drive will do. I have tried plenty of NVME drives recently when testing them for my TB4 enclosure and found the best for speed in the enclosure to be WD SN770 beating my higher end SN850 by 30%+. It's a bit counterintuitive though for a DRAM-less drive to beat it's big brother in testing but it did.

Phison drives are the mid tier drives when it comes to performance.

I have a couple of them PNY CS3030 / BPX Pro and they work fine but, have their own issues compared to the SN850. The SN770 is a gen4 drive and can hit 5GB/s internally though and the only difference is how it handles data. I found I could really get performance out of it by multi streaming data to the drive vs just dumping a single thread to it.

So, it really depends on how you are using them as to how they perform. The SN770 makes use of the system RAM vs having it on board like traditional drives. It still depends on the underlying physical connections and overall system build though as well to achieve high numbers when it comes to drives.

Thanks. I guess I'll pay a lot more attention to the "Terabytes Written" than to the warranty, going forward.

It's similar to cars 50k miles or 5 years. Whichever you hit first expires the warranty. Durability is more related to the chips being used. Drives used modestly outlast any warranty period.
