Question Looking for NVME with great write performance/price - Need Advise!

[bdk74]

Working on a multiple build project that will have focus on write performance onto the nvme at gen4 speeds.

Been always the fan of the WD brand (i.e sn770) but with the price point and qty I'm planning to purchase looking for alternative.

I've noticed Team Group MP44L 1TB/2TB variant has a good performance on paper.
 

Application will run dd test on interval basis as synthetic 1GB test where 1TB disk should run around 4-6 at the same time and 2TB disk 5-10 tests:

dd if=/dev/zero of=sb-io-test bs=64k count=16k conv=fdatasync; rm -rf sb-io-test

 

PS. Techpower up also mention this drive stating got a small cache but writes outperforms other vendors which I don't get it how:

Just like all other modern TLC drives, the MP44L comes with an SLC cache that absorbs incoming writes at high speed, but uses three times the storage to do so. Our testing reveals that the SLC cache is sized at 63 GB, which is surprisingly small for a solid-state drive in 2023. On the other hand, sustained write performance is better than most competitors—we were able to fill the whole 1 TB capacity at 1.45 GB/s, which is a huge improvement over drives such as the WD Blue SN570 (590 MB/s), Samsung 980 (600 MB/s), WD Black SN770 (630 MB/s) and XPG Atom 50 (805 MB/s). So if you plan on writing a lot of data regularly, do prefer the MP44L.

tbh not entirely sure what you wrote, but lexar nm790 (especially the 2TB) is great price to perfomance drive, at least where i live, i have it for like 6 months, and so far no issues. It doesnt have DRAM cache, but i preffer it, that way if i have to unplug my pc (which has happened), there's way less chance that i will lose my data

Just little context on what the drives will be used for.. Seems like Lexar is on par with 770 but higher read/write - I appreciate it. I wasn't aware lexar is doing nvme now?!

@MiszS would you be able to run the dd command for me?! 1TB got nice TBW but 2TB is not doubled but at 1500 its still fine.

I have a few SN770s, great drives for the price.. of course not the bestestest.. but good value. I paid 63 CAD for each TB stick.

Any decent SSD on 176l TLC micron, on good controller will do.

anything, there are lots of SSD on this NAND and Phison E18, especially 2TB versions, were SSD can leverage better controllers and more available NAND.

 

the MP44L have good NAND 176L TLC micron, but weak controller Phison E21T (1-core, 4-channel, DRAMless )

 

the good sustained writes are all thanks to the good NAND used, but the controller is holding it back, especially in 2TB version.

what command exactly do i run?

I don't believe dd bench can be executed on windows:

dd if=/dev/zero of=sb-io-test bs=64k count=16k conv=fdatasync; rm -rf sb-io-test

uhh so i kinda forgot to reply, but the test said around 500MB/s, i do use it in a PCIe gen 3 system, but idk why is it that low in this test, on crystaldiskmark when i ran windows it was around 3500MB/s, which is close to the theoretical max
