WD blue SN570 1TB vs Kingston NV2 1tb

[Kyrpousin]

I'm trying to choose parts for a budget build with a ryzen 5600g and I'm between those two m2 Drives. Could crucial P2 be another option? What's the best of all 3?

All of them are pretty much same, Crucial P2 about 1000MB/s slower on read speed than both M.2s,

 

WD and Kinston same read speed, WD 900MB/s faster write speed,

 

in the end they will run about the same, the only difference is Crucial will load games few seconds slower, maybe,

but once the game is loaded there shouldn't be big difference.

Also TBW, WD and Kingston probably bigger longevity than Crucial. (2x)

 

In gaming WD and Kingston will perform same, even when WD has faster write speed, read is more important,

 

Crucial is good choice also, because the difference won't be really noticable.

 

Kingston and WD are both good,

 

Crucial is a good buy too if it's way cheaper.

Kingston NV2 is hardware lottery QLC trash, Crucial P2 can drop to USB 2.0 sustained write speeds, so I would rather buy the WD SN570.

oh wow, they don't even mention memory type in NV2 anywhere

SN570 is  TLC based, good endurance, good performance ... 3.5 GB/s read, 2.3 GB/s write, 300 TBW endurance, 5 years warranty

a bit small write cache at around 12 GB  (if you copy something to it, it gets super fast speeds until those 12 GB are written, then cache is full and speed drops to around 500-600 MB/s) When you're done writing, within 1-2 minutes those 12GB are moved to permanent storage and you get fast write speeds again.

 

Kingston NV2 is either with TLC or with QLC ... most likely QLC.  It's pci-e 4.0 only on paper, doesn't have the speeds, 3.5 GB/s read. 2.1 GB/s write, the TLC version was supposed to be 320 TBW endurance,  but only 3 years warranty

It can use the full free space as a write cache in pseudo-SLC cache (ex 500 GB free space = ~ 100 GB SLC write cache) - it writes that amount at fast speeds, around 2 GB/s then when this cache is full speeds drop to around 200-240 MB/s because it has to convert that pseudo-SLC memory back to QLC mode.

 

Crucial P2 ... 2.4 GB/s read ,1.8 GB/s write, originally used TLC but older generation TLC so a bit slower but with more endurance.... current versions use QLC like on NV2

Can use up to 200ish GB of pseudo-SLC write cache (depending on how much free space there is, same deal, free space / 4 = pseudo-slc write cache)  but once the cache is full speeds drop to < 50 MB/s

 

SN570 is more consistent even though it has small write cache.  Look also into WD SN770 and  Samsung 580, sometimes they're discounted

 

Crucial P3 Plus seems to have good firmware giving it good performance so could be alternative if the above are just too expensive... it's still QLC based but behaves like NV2, can use all free space as write cache giving it decent write speeds.
