What's a turbo Z drive? Can I swap it for a Samsung 860 Pro M.2? Can I have two M.2 devices to raid it? I don't want to lose my work. Edit: Liliputing says "There’s a 2.5 inch drive bay for a hard drive or SSD and an M.2 SATA SSD slot." ( https://liliputing.com/2016/11/msi-trident-compact-vr-ready-... )
It's a 4-way M.2 NVMe raid card, which HP has ignorantly decided to populate with seemingly mediocre SSDs instead of the current gen flagships from Samsung or Intel. You can remove the included SSDs and populate it with up to 4 960 Pro SSDs for what I imagine would be 14/8 GB/s sequential read/write performance. Unfortunately there's no way to buy it without the included SSDs, so you're better off with the unpopulate…
Ah, brings back memories of buying HP servers several years ago. The only way to get the servers we needed was to buy servers pre-shipped with inadequate RAM and drives, rip it all out, and then install new drives and new RAM (purchased at the same time from HP, for an inflated price of course). We were left with a pile of essentially useless SAS drives and ECC RAM, and still had to do all the assembly in-house.
I've never had so much trouble getting a company to accept several tens of thousands of dollars before.. or since.
That project explicitly specified HP hardware, and as far as I know we never bought HP servers again after that experience.
