Hi there,
I have Lenovo E32 Tower PC, on my home lab. I run Proxmox on it and play with different Open-source technologies. In summary I have more than 15+ (VMs+Containers) which does a lot of random I/O. That's why I decided to replace my old SSD drives with new PCIe disks.

As you may know, there a plenty of choices on the market, when we speak about SSD/NVMe. Some of the disks comes with M2, others with U2, there are also different sizes, the PCI bus has its speed, for instance I have PCIe 3.0.
So can you help me to choose the right so called "converter" card and the right NVMe disk for my setup.

Here is the main-board: https://www.amazon.ca/Genuine-Lenovo-Thinkstation-Motherboard-03T6749/dp/B01NCSD38V

I might be wrong, but I think this guy can do the job: https://www.sabrent.com/product/EC-PCIE/nvme-m-2-ssd-to-pcie-x16-x8-x4-card-with-aluminum-heat-sink/

With such disk: https://www.sabrent.com/product/SB-...ernal-ssd-high-performance-solid-state-drive/

Thanks in advance.

I have 4 SSD disks connected directly on the mainboard via SATA cables.

What's the capacity of those 4 SATA drives?
Will one 256GB M.2 drive be enough to replace them all?

Note - it's highly unlikely for your system to be able to boot from NVME device. BIOS support is required for that.

What storage is in the machine now?

Is there a gpu installed?
If so which pcie slot is it using?

Ok, let me share with you some results I made in the past related to performance checks:

From the tests above I consider that only RANDOM reads/writes are quite slow, and this is completely normal, because during the tests CPU load is almost 100% usage.

The block size also matters, not sure for those SSDs the block size is 4k (filesystem)
