Samsung 960 Pro Performance after 31 TB of writes

These SSDs are awesome thanks to their MLC NAND, they still perform today, as they did when I first bought them.

I've written 31TB to each of so far while on RAID 0


When they were brand new:






Now after 31TB of writes:

 

lets just hope that we will still have the option to choose MLC drives in the future im worried that with the advent of QLC, TLC will be the new "performance standard" with QLC for budget storage *rolleyes*

in any case, QLC actually IS quite interesting for mass storage / archivation purposes and I could imagine myself getting a large QLC SSD for media stuff instead of the usual HDD

 

Phoenix, I thought R/W speeds will be beyond 5GB/s on RAID. I saw AMD TR on RAIDed 960 PRO was able to reach 6GB Reads and 5.xGB/s.
Does iGPU and dGPU influence SSD scores while benching?

 

throughput on laptop systems is always lower than on comparable desktops, even when we talk high end DTR. that, plus software raid solution vs. TR going straight through the CPU could be another factor. in any case, at those levels i dont think itll make a difference to have either 3GB/s or 5GB/s throughput what matters most is 4K speeds and those are excellent in @Phoenix `s case

So which 4k workloads actually say about drive perf? 4k Q8T8 or 4k Q32T1?

 

4k Q1T1 are the most important in everyday usage, Q8T8 are somewhat important and Q32T1 are very seldom found in regular user behaviour. that goes more into server / databank / professional territory.

 

And most part of the written 31TB is probably different, + same OS Builds and several formats MLC Nand FTW

 

yeah i was thinking along those lines as well *lol* ive had my 1tb 850 pro for 3.5 years now and just broke 27 TB in writes. 6.5 years and 273 TB of warranty left

Tell me one thing, I'm confused regarding SSD warranty, does this depend on actual time period or just TBW?
Because if I complete 5 yr warranty of 850 evo with 20TB of writes and there's ton of endurance left to reach to 70TBW, will that ensure I'm covered by warranty by seeing TBW solely?

 

its both. manufacturers publish a time span and TBW that are covered under warranty. whichever limit you reach first, counts. so if you reach 70 TBW first before 5yr are over, warranty is out. on the other hand, once 5 yr run out before 70 TBW are reached, your warranty is out, as well

This is the normal for automobiles here home as well. I think it's the same everywhere.

 

Okay so that means I have to get new drives anyway. 850 EVO has written only 700GB and PM951 has written 5TB after 1 yr usage.

 

only cuz the warranty is out doesnt mean u need to get new drives especially when the SMART attributes state a good health

 

The health has dropped to 99% after year and a half. So theoretically it will last for another 99 years if I'm alive. OR 10 yrs on constant usage.

 

yep that sounds about right for regular usage

 

Yes, it very much depends on "CPU's" per pcie lane revision...

How Does a Samsung 960 Pro SSD Perform Over Time?

Why Raid 0 and risk data corruption if not benefitting from any significant speed improvements?

 

And what 4K write scores is expected from single 960 Pro?

 

I’ve been doing RAID 0 on SSDs since they came out. They don’t fail like HDDs and I have automated daily backup to my external drives using a professional program called SyncBackPro so let me worry about my data and smoke your sequential read / writes and also smoke your 4K random rights while I’m at it

 

Smoking hot Phoenix...

 

Not sure whats so surprising that the drive is performing like day one after 31TB of writes. Regardless of MLC/TLC performance should stay roughly the same till the end of their rated lives due to proper wear leveling and TRIM unles you have a really really ****ty drive with a terrible controller or if TRIM is disabled/lacking like in very old drives. Even in TechPowerup's SSD endurance test the 850 Pro even way past its rated TBW performed near spec.

Rather than just Terabytes written, it's the performance when the drive is near full that usually takes a hit as there is less free space to move data around for the likes of wear leveling/garbage collection and so you have much higher write amplification/wear in addition to lowered performance. The 960 series from reviews I have seen does pretty well performance wise even when at 90% (83% in reality as drives come with inherent 6.8% OP) full though write amplification would still be higher when filled that much.
