Hi Experts,

I need some help please. I have an old-ish Asus Maximus IX Hero motherboard with PCI-E 3.0. Looking for an NVMe SSD upgrade as my current Hynix 256GB just doesn't cut it any more. I wanted to buy the Samsung 970 Pro 1TB (MZ-V7P1T0) which is one of the fastest PCI-E 3.0 SSDs but the price is £219. I then looked at the Samsung 980 Pro 1TB (MZ-V8P1T0BW) for £189 but that is PCI-E 4.0. Is it worth getting the 980 Pro or is it not backwards compatible? Will it run as fast as a 970 Pro would or it would be slower?

Many thanks for your help!
Krisztian

By most measures and for most use cases, the 980 PRO is actually superior to the MLC-based 970 PRO. The addition of PCIe 4 support helps the 980 PRO deliver higher speeds than its predecessors, even though that's more forward-looking than an immediate benefit. The shortcomings relative to a hypothetical MLC-based PCIe 4 drive are also mostly hypothetical; workloads that truly require more write endurance than the TLC-based 980 PRO can provide should probably be handled by an enterprise SSD rather than any consumer/prosumer product.
Performance wise, the 980 PRO will be slightly faster at PCIe 3.0 x4 speeds, but if you are a super heavy data writer, the 970 PRO has a higher TBW warranty since it uses MLC NAND. All of the pro/cons are listed in the review.
