October 30, 20232 yr Morning all, I am looking to speed up access to my system by expanding the cache pool with a number of NVME drives. The easiest way to do this is with an NVME expansion card, like this: https://www.lenovo.com/us/en/p/accessories-and-software/memory-and-storage/memory-and-storage-hard-drives/4xh0v09766? Has anyone used this, or has recommendations for something similar? I want to use a card like this for the cooling and all--in-one-place My current setup has one cache drive in a motherboard slot, one in a cheap PCIe to NVME adapter. That's a pain because the PCIe to NVMe one doesn't get much cooling so it tends to get a bit toasty. So, I was looking to get one of these multi-drive expansion cards, put in several SSDs and build a large cache attached to the main array. Any thoughts on that?
October 30, 20232 yr From what I can see, and despite the price, that adapter requires PCIe bifurcation, so make sure your board supports it, and in that case might as well get a cheaper adapter like the Asus hyper m.2 card.
October 30, 20232 yr Author Well part of the reason for getting this more expensive card is that it is going into a Lenovo Thinkstation system, so I wanted to maintain the single vendor if possible. I'll check with Lenovo on what support is offered for that. Does the Asus hyper m.2 card work with Unraid?
