For an AM4 or AM5 gaming build, the best SSD is usually a PCIe 4.0 NVMe drive such as the Samsung 990 Pro or WD Black SN850X; choose the Crucial P3 Plus when you want capacity at a budget tier, and consider PCIe 5.0 drives like the Crucial T705 or Samsung 9100 Pro only if you are on AM5 and have a specific reason to pay for peak speed. Tom’s Hardware, PCGamesN and GamesRadar all treat PCIe 4.0 as more than fast enough for current games, and Newegg’s guide suggests 2TB as the sensible baseline now that big titles often exceed 100GB.

AM4 vs AM5: What Your Motherboard Supports

This is the first thing to confirm. AM4 boards (Ryzen 1000 to 5000 series) support PCIe 3.0 on some chipsets and PCIe 4.0 on the others, depending on the CPU and chipset: X570 and B550 boards support PCIe 4.0 with a compatible Ryzen CPU, while older X470, B450 and A320 boards are generally limited to PCIe 3.0. AM5 boards (Ryzen 7000, 8000 and 9000 series) support PCIe 5.0 for the main M.2 slot on many X670E, X870E and some B650E and B850 boards, and PCIe 4.0 on others. Check the motherboard manual for the slot speeds, because the second M.2 slot is often slower than the first.

NVMe drives are backward compatible. A PCIe 4.0 drive in a PCIe 3.0 slot runs at the slower speed, so buying a PCIe 4.0 drive for an older AM4 board still works and leaves room to reuse it later. For a PCIe 3.0 board with no plans to upgrade, a cheaper drive is enough, because the interface limits the speed to roughly 3,500MB/s.

PCIe 3.0 vs 4.0 vs 5.0 for Gaming

Interface Typical top sequential speed Does it matter for gaming?
PCIe 3.0 x4 about 3,500MB/s Fine for most games; slower in large copies
PCIe 4.0 x4 about 7,000MB/s The practical sweet spot
PCIe 5.0 x4 10,000MB/s and above on top drives Rarely changes load times in current games; helps big file transfers

Reviewers note that game load times are limited by the CPU and game design as well as storage, so the gap between a good PCIe 3.0, 4.0 and 5.0 drive in actual gameplay is small. TechSifted says the 990 Pro and SN850X are Gen 4 and more than fast enough for every current game. DirectStorage support is still limited to a handful of titles.

DRAM Cache and Why It Matters

An SSD with a DRAM cache keeps its mapping table in fast memory, which helps sustained performance and consistency when the drive fills up. DRAM-less drives use a portion of system memory (host memory buffer) or controller memory instead, and are usually cheaper. For a game library drive, which mostly reads, a DRAM-less drive is acceptable. For your boot drive and heavy file work, a DRAM-equipped drive such as the 990 Pro or SN850X is a safer choice. Newegg’s guide suggests pairing a capacity drive like the P3 Plus with a faster boot drive.

Heatsinks and Thermals

Many motherboards include M.2 heatsinks or covers. PCIe 4.0 drives generally run fine with the motherboard heatsink; PCIe 5.0 drives run hotter and typically need a good heatsink and some airflow. If your board has no heatsink, choose a drive sold with one, such as the WD Black SN850X heatsink version, but measure the clearance first, because a tall heatsink may collide with a graphics card or CPU cooler. Do not stack a heatsink on top of one already supplied by the motherboard.

1TB or 2TB?

Newegg recommends 2TB as the 2026 baseline because modern games regularly exceed 100GB each. A 1TB drive loses space to Windows and updates, leaving room for a handful of titles. If a 2TB drive is outside your budget, buy a 1TB main drive now and add a second M.2 SSD later, as long as your motherboard has a free slot.

Best SSD Under a Budget (Without Prices)

For the budget tier, the Crucial P3 Plus is the usual recommendation for gigabytes per spend, according to Newegg. Its rated speeds of 5,000MB/s read and 4,200MB/s write are lower than flagship drives but fast for game loading. Look at endurance (TBW) ratings, warranty length, and whether the drive has a DRAM cache before choosing a budget model. Beware of unknown brands with similar names and always read the specification sheet.

Decision Table: Pick X If…

Pick this If you
Samsung 990 Pro want the benchmark Gen 4 drive for a boot and game drive
WD Black SN850X want a fast Gen 4 drive with an optional heatsink and strong console compatibility
Crucial P3 Plus want the most capacity per spend for a game library
Crucial T705 or Samsung 9100 Pro use AM5, move large files often and can cool a PCIe 5.0 drive
Any PCIe 4.0 drive on an AM4 B550 or X570 board want a drive that will carry over to a future build

Alternatives

  • SATA SSDs: Slower, but acceptable for older systems or secondary game storage.
  • Hard drives: Only for mass storage of rarely played games.
  • External NVMe enclosure: A way to add game storage without a free M.2 slot.

Installing and Setting Up an NVMe Drive

  1. Power off the PC, switch off the power supply and unplug it, then touch bare metal on the case to discharge static.
  2. Find the M.2 slots in the motherboard manual and note which one connects to the CPU and which to the chipset; the CPU-connected slot is normally the fastest.
  3. Remove the slot heatsink if present, insert the drive at an angle, press it flat and secure it with the screw or latch.
  4. Refit the heatsink, making sure any thermal pad film is peeled off as the maker instructs.
  5. Boot, then initialise the drive in Windows Disk Management if it is a second drive.

Some boards disable certain SATA ports when a second M.2 slot is used, so the manual is worth a read before filling every slot. Updating the drive firmware through the maker’s utility is a common recommendation from reviewers.

Cloning vs Fresh Install

If you replace a boot drive, you can either clone the old drive with the maker’s migration tool or do a clean Windows install. A clean install avoids carrying over old drivers and is simple on a modern system; cloning saves time when you have a lot of software configured. Whichever you choose, back up personal files first, because a failed clone or install can wipe data.

Endurance and Warranty

Makers list endurance as terabytes written (TBW) along with a warranty period, commonly five years for mainstream drives. Game libraries are read-heavy, so even budget drives rarely approach their rated endurance in normal gaming. Pay more attention to warranty terms and brand support than to peak speed numbers when comparing similar drives.

Frequently Asked Questions

What is the best SSD for gaming on an AM4 motherboard?

If your board supports PCIe 4.0 (such as B550 or X570), a drive like the Samsung 990 Pro or WD Black SN850X is the common pick. On a PCIe 3.0-only board, a cheaper drive is enough because the interface caps speed.

Is a PCIe 5.0 SSD worth it for gaming?

Reviewers generally say no for games alone, because PCIe 4.0 drives already load games quickly. PCIe 5.0 mainly helps heavy file transfers and costs more in heat and money.

Do I need a DRAM cache on a gaming SSD?

For a pure game library, DRAM-less drives work. For a boot drive or mixed use, a drive with DRAM cache holds performance better when it is full.

Will a PCIe 4.0 drive work on my AM4 board?

Yes, NVMe drives are backward compatible, but they will run at the slower speed of the slot. The drive can be moved to a new build later.

Do I need a heatsink?

Most PCIe 4.0 drives work with a motherboard heatsink. PCIe 5.0 drives need more cooling. Check clearance before adding a taller aftermarket heatsink.

How much storage do I need?

Newegg suggests 2TB as a baseline in 2026 because many games exceed 100GB. If you must start with 1TB, plan to add a second drive later.
