[SOLVED] Which NVMe to buy, higher sequential or higher random access?

[Schereizer]

I'm now about to buy an NVMe SSD but I have two candidates, Crucial p2 and Verbatim Vi3000 (both 500GB).

The data for CrystalDiskMark are as follows :

Both Test Count: 5
Both Test Size: 1GiB

Crucial - READ MB/s - WRITE MB/s
SEQ1M (Q&T1) - 2426.56 - 1916.32
SEQ1M (Q1T1 - 1580.00 - 1798.29
RND4K(Q32T1) - 291.83 - 153.76
RND4K(Q1T1) - 49.41 - 122.87
Advertised Speed - (READ) 2400MB/s - (WRITE) 1900MB/s

Verbatim - READ MB/s - WRITE MB/s
SEQ1M (Q&T1) - 1979.96 - 1844.85
SEQ1M (Q1T1 - 1284.71 - 1750.69
RND4K(Q32T1) - 1340.08 -1737.16
RND4K(Q1T1) - 57.32 - 190.14
Advertised Speed - (READ) 3100MB/s - (WRITE) 2900MB/s

I noticed that Verbatim has higher RND but lower SEQ compared to Crucial but I don't have a clean image about what RND do and when do they matter. I'm planning to use it for photoshop and premiere pro for rendering videos (and a little games) so I often launch applications . For now I want to know which is better and a few easy tips on what to check when buying these things or if you can suggest a better one for the price. Buy the way both has same price for about $72. Thank you...

Much depends on type of usage but I doubt you would see any difference outside of benchmarks !!!
Sequential speeds are more important to continuous large file data transfer but only until cache is not exceeded, after that it will drop like a rock.
RND (Random)(4K) most often used by Windows background work so it may be a bit faster.
Things can change in surprising ways if test file size is changed.
For overall practical performance, cache existence and/or size is more important than those numbers.

Stick with a Crucial and don’t bother with SSDs like verbatim from crappy names that can’t be trusted

lots of good drives. This the only two choices?
