Hello everyone) I have a laptop Aspire 5 (A515-51G-57TV), as far as I know, I have the opportunity to install m.2 SSD (22*80) on this computer (if I am mistaken, correct me please).

I would want to buy ssd 256GB 

  m.2. SSD models differ in 
  • Sequential Read Speed
  • Sequential Write speed
  • PCI-Express Interface
  • Dimension (W x H x L)
and a number of other parameters.

Are there motherboard or CPU (my CPU is i5-7200u) limitations on Sequential Read Speed, Sequential Write speed, PCI-Express Interface?
I would not want to overpay for unused features of SSD. Thank you so much.

    Yes, you may use a 256GB m.2 SATA SSD interface shown in the image below. Some m.2 PCIexpress or nvme SSD interface may also work if the slots are the same. The read/write speeds and dimensions are what they are. Shouldn't matter for your system. The safest bets are the m.2 SATA SSDS for your model. Jack E/NJ

    Some nvmes won't fit in the connector IF its single key slot on the bottom isn't on the left. This is called a B key slot. Some nvmes have the slot on the right, called M key slot. Look again at the bottom of the cards in the images above. The m.2 SATA SSDs have two slots, called B+M key slots. If the nvme you get is M key slot on the right, it won't fit because the B slot is filled  and will bump up against a plastic B key in the connector. If you get a B key slot nvme, it should work but only at SATA3 speeds, not nvme. So it's not worth paying extra for.  Again, an m.2 SATA3 SSD is your safest practical bet.Jack E/NJ
