Suggestions for SSDs for new Precision 7780, please

Check out the SK Hynix Platinum P41.  Top tier performance, made for gaming yet performed excellent in workstations.  Highly rated and well liked by reviewers.

I watched a couple reviews on the SK hynix Platinum P41 and it is pretty impressive.

I was leaning towards the WD Black SN850X. However, the review on that also stated that it runs hot.

As of now, I am leaning towards your suggestion, SK hynix Platinum  P41.

Is that what you are using, so what are you using it in?

Not using it personally.  But did some research when helped out someone to replace an overheated RAID build.  It resolved the issue.  No more throttle with high temps operations in workstation.

YRMV depending on usages and applications.  Check out the top critical review, even a bad benchmark of RAID performance was still considered very decent.

I was looking for some higher speeds in an SSD.
I was hoping for something closer to 7,000MB/s.
That was why I was not looking at the Samsung 970 EVO Pro. It is rated at 3,500MB/s.
I was leaning towards the WD Black SN850X because it is rated at 7,300MB/s, but the reviews say it runs hot.

I did not really consider the WB Black SN850 because it rates good for gaming and not for an editor, which I am. I was also looking for a 4TB SSD and they only go as high as 2TB.

With that said. I am now considering a 2TB instead of 4TGB.

I compared the SN850 to the SK Hynix Platinum P41. The SK Hynix Platinum P41 has a better benchmark but about the same heat and the SK Hynix Platinum P41 is almost $100 cheaper.

In my Precision 5770, I have a Crucial CT2000T700SSD3 (2TB) and a CT4000T700SSD3 (4TB) inside, and both are 5th gen NVMe SSDs running in 4th gen NVMe slots.  For large files (>1GB, e.g., movies), I get 1-2.5 GB/s.  For small files (<10MB, e.g., Word and PDF docs), the transfer is always much less, but still in the 50-250 MB/s range.  But remember that in real-life, small files will always transfer slowly because of the file system:  large numbers of small files create overhead in managing directories, and managing directories forces random reads/writes (IOPS rating becomes important).  Small numbers of large files benefit from sequential read/writes (MB/s rating becomes important), so you'll want to check both ratings.  Lastly, very few (reasonably-priced) computers can actually get to the 7GB/s range even if they have NVMe SSDs that are rated at that.  As an example, the Crucials are rated in the 11-12GB/s range, but the 5770 doesn't get anywhere near that, even though it has memory rated at 4800MHz.

@birdcatcherfbb0d6​ this is a drive-by note. The real reason small files take longer to copy is because of CRC. Each one has to be validated and this takes significant cycles. An easy way to avoid this problem, if it is appropriate for your case, is to zip the files into a single archive and copy it... but not useful for all cases.
