How to choose ssd for server?

there is a server on it linux file hosting, apache and all sorts of rubbish a lot, everything works slowly and starts to slow down so cool, I want to put ssd on 1tb, the problem is that I don’t know which one will fit there, I didn’t have much to do with servers
now it’s standing there raid array for 8 disks, it is essentially not needed, although it is safe, the

motherboard of the
Supermicro X8DT3 server
https://www.supermicro.com/products/motherboard/QP...

I don’t even know what form factor is needed, in theory PCI Express ?

I ask for help in general

If you have PCI-E 3.0 (you have them), then you can consider the option with 970Pro with an adapter like JEYI MX16 but you need a heatsink (970Pro is inhumane) as an option JEYI WS is certainly inhumane, but not a SATA SSD

Your friend has a motherboard with a Broadcom 1068E 8-Port SAS Controller;
RAID 0, 1, 10; RAID 5 optional
6. 6x SATA2 (3 Gbps) Ports via
ICH10R Controller
The raid just created your speed plus reliability! If we consider raid10 800 read/400 write, and if raid5 then 700 read/100 write! But if you put an ssd drive you will get 300/300 due to the fact that you have a sata2 controller! Nvme you will not put! And here you go back to the raid

If you have lvm then try to cache the data on a fast disk.

It is not known what raid these 8 disks are currently in. Suppose at 5. Then the transfer to the 10th will help even on this hardware.
And so, separate models are produced for servers. It is possible to pick up on the same Nix, it indicates what is approved and what is approved for the database.
Servers are divided into read intensive, mix use, write intensive segments. Division by DWPD indicators. You need to understand the load on the disk to choose. Under the web server, you can also read intensive, but if the database is actively used, then mix or write intensive.
In addition to these parameters, there is data loss protection for the server segment - capacitors inside the ssd itself to drop from the cache to disk.
I would take a couple of read or mix, put them in the mirror. You can’t squeeze the maximum out of them, but obviously more than they should give now.
