This is an SSD and it is no longer a good one, there are much faster models, this one for example would be better and doesn't cost much more, however: they all don't fit in the HP 850 G1, because it doesn't have an NVMe expansion slot for 2280s, but it needs the small M.2 NGFF (B and M Key) SSDs, which are also sometimes called mSATA. The speed they achieve is only just what a normal 2.5 inch SSD could do.
A different key would also have to be chosen, since the space provided for it only fits the smaller 2240 modules, I would install a 2.5 inch SSD instead of such a small SSD.
That would be super suitable:
Crucial BX500 (1000 GB, 2.5")
