[SOLVED] nvme gen 4x4 in a 3 x 4 ssd port laptop

[rook198]

Hello guys, I'm new here! so, I have a Legion 5 15ARH05H which has these storage mods :
=> HDD/SSD mode: • One 2.5" drive slot, supports 2.5" SATA HDD • One M.2 2280 PCIe Gen 3x4 slot, supports M.2 2242/2280 SSD
=> Dual SSD mode: • Two M.2 2280 PCIe Gen 3x4 slots, support M.2 PCIe 2242/2280 SSD
I got my laptop with the HDD/SSD mode, and I want to replace my HDD ( it's replaceable) with a 2280 SSD gen 4x4. what's the max read/speed I can expect? should I just buy a Gen 3x4 ssd? or go for the 4x4 gen? I got my eyes on an MSI spatium M480 1TO SSD 2280 M.2 gen 4x4 with 7000/5500 MB/s read/write for 184 euros, and the best option ( in my country) in gen 3x4 is a PNY CS3030 1TO SSD M.2 with 3500/3000 MB/s read/write speeds for 161 euros. sorry for my bad English and thanks a lot for your patience!




thanks a lot

There is zero need to install a PCIe 4.0 SSD on a 3.0 port.

Performance is dictated by the slowest device in the chain. Here, the 3.0 port.

Depends on which 2280 you get and what benchmark you run.
I have a wd 750 the bench I ran showed R/W of >3000/>2400.

3500 MB/s

You will be hard presses to tell which is faster, a sata ssd, a pcie3.0 nvme ssd, or a pcie 4 nvme ssd.

I am a big fan of the samsung ssd migration app.

Tool & Software Download | Samsung Semiconductor Global

Download various software related to your product, including Samsung Magician, designed for use with Samsung's memory products, and find related information.

www.samsung.com

Install any m.2 samsung and run the app to move your C drive to the ssd.
The ssd needs to be large enough to hold the used contents of your HDD with room to grow.
Yes, you will pay a bit more, but you will get one of the faster and more reliable devices.

Then you can remove or repurpose the hdd.
