The laptop does not see ssd why?

Question

Solid State Drives

Hello, I bought a Transcend ts480gssd220s ssd, I want to replace hdd with ssd, but the laptop does not see it. Dell latitude e 6430 my laptop. I tried to change UEFI to Legacy in BIOS, disabled Secure Boot, but zero in phase.
What could be the problem?

So, just in case, I'll write it down here, so that later I google it. It concerns not only the E-series and not only DELL.
E-series laptops have Half Mini 2 PCIe connectors, in particular - for WAN / WLAN / WiFi, WWAN, and other modems.
Very often the question arises, is it possible to shove an mSATA SSD there, and, even cooler, boot from it.
When answering this question, you need to understand that a unified mini card slot can contain pci-e PCI-express buses (both 4x and "truncated" 1x) AND / OR mSATA AND / OR USB (moreover, mainly , 2.0).
Accordingly, in order for most mSATA solid-states to work, the mSATA lines must be mated. board (to the SATA controller). For example, this is not the case with the Latitude E5530.
"Quick" identification method: if the port is signed on the case plastic as mSATA or mSATA/WWAN, then mSATA will work!
For reference: most WWAN modems use USB lines.
Most mini card pci-e >> SD memory card converters (there are some, and it makes sense!) use USB. However, there are also pci-e. From which the immediate conclusion is that it makes no sense to insert cards "cooler" than UHC-I into them, there will be no speed increase due to the USB 2.0 bandwidth ceiling - you can count on 30 Mbps at the peak.
Even if mSATA is not routed to the port, you can insert an SSD there, provided that it carries a controller "on board" (most often it is an IDE / PATA controller). These are fairly rare, comparatively expensive, limited in capacity, and outdated cards, but they are the only way to get any fast partition on an SSD and (if supported by the BIOS) make it bootable (and flash the system onto it).
An example of such an SSD - SuperTalent IDE Half Mini 2 PCIe SSD, exists in the form of a maximum of 64 gigs on a single bar of full (not half) size.
Another example is Intel Turbo Cache Memory, which was planned by the developers of the early E-series to be shoved there initially in the top-end configuration. They exist in forms of 0.5-4 GB and are suitable, in my opinion, only for Windows ReadyBoost, Linux swap or similar swap/hybrid cache partitions.
