Question 870 EVO 2 TB has slow random reads/writes

[ctg1412]

Hello,

Just got a lightly used SSD 870 EVO 2 TB from Amazon.

I was wondering if those benchmarks look normal?

Compared to this review and whats advertised it looks like my random writes are 50% lower.

How full is your disk ? Random writes are first to slow down as disk capacity is used up. Make sure it's trimmed regularly so garbage collection can zero blocks with deleted data. Otherwise it will have to erase those blocks before writing new data to them and that takes 2 cycles longer than if blocks were zero.

Unfortunately it is actually completely empty. I think I will need to replace it.

Here is my 1TB 860 EVO

Yours are a little bit low, but not disastrously so.

Was this a used drive?
What does CrystalDiskMark show as the total TBW on this drive?

Looks okay to me...maybe try a different benchmark like CrystalDiskMark...

Sorry I am unsure what TBW is. The drive is relatively new, got it from amazon warehouse so I can still return.

It has 3.7TB written on Samsung magician which is not a lot (but also clearly shows usage).

Here is the CrystalDiskMark test result:

Run CrystalDiskInfo. Post the screencap here.

3.7TB is trivial.

Again, you knowingly bought this used?

Those numbers are acceptable. Some are a bit on the low side, but that may not be caused by the drive. For example, seq. writes might be a bit lower due to the chipset on the motherboard. 4K might be a bit low due to your CPU. If you're testing in the OS (Windows), software and caching may also have minor impacts on benchmark results. There are many factors that may impact these values. I'm guessing your system is older or a prebuilt but I may be wrong.

I have a new Samsung 2TB EVO SSD and this is its performance with a nearly full capacity:
