The Samsung 990 EVO Plus 2TB is the strongest all-around M.2 upgrade here for a gaming laptop with a standard 2280 slot, thanks to its TLC flash, a published endurance rating of 1,200 TBW at 2TB, and PCIe 4.0 x4 speeds. The Crucial P310 2TB in the 2280 size is a close alternative when capacity and raw speed matter more than endurance. “M.2” describes the small gumstick form factor, and in a gaming laptop upgrade the two numbers that matter most are the length (2280 or 2230) and the interface (PCIe Gen4 NVMe). Below, each of the six drives is matched to the kind of laptop and player it suits.
Our Top Picks
Top 3 picks at a glance
Quick List
- Samsung 990 EVO Plus 2TB – best for a long-term, high-endurance 2280 upgrade
- Crucial P310 2TB (2280) – best for large game libraries on a Gen4 laptop
- Crucial P310 1TB (2280) – best for a straightforward first upgrade from a small stock drive
- KingSpec 2TB Gen4 – best for chasing the highest rated read speed in this list
- Fanxiang 1TB Gen4 – best for a modest 1TB upgrade with a bundled heat spreader
- Crucial P310 2TB (2230) – best only for handhelds and laptops with a short 2230 slot (runner-up for standard laptops)
Which One Is Right for You?
| If you… | Choose |
|---|---|
| Want TLC flash and the strongest endurance rating for a laptop you plan to keep for years | Samsung 990 EVO Plus 2TB |
| Need 2TB for a big library and your laptop has a standard 2280 slot | Crucial P310 2TB (2280) |
| Are replacing a small 512GB drive and only need 1TB of Gen4 storage | Crucial P310 1TB (2280) |
| Care most about the highest advertised sequential read speed among the 2TB options | KingSpec 2TB Gen4 |
| Want a 1TB Gen4 drive from a lesser-known brand that includes a heat spreader | Fanxiang 1TB Gen4 |
| Have a Steam Deck, ROG Ally, MSI Claw or a laptop with a 2230 slot | Crucial P310 2TB (2230) |
Before comparing speeds, open your laptop’s specifications and confirm which M.2 length the slot takes. A drive that does not physically fit is useless regardless of how fast it is. After that, decide on capacity, since modern AAA games often consume well over 100GB each, and then weigh endurance and warranty against the headline speed figures.
All 6 Picks in Detail
1. Samsung 990 EVO Plus 2TB – Best for a Durable 2280 Upgrade
As an Amazon Associate we earn from qualifying purchases at no extra cost to you.
The 990 EVO Plus is a PCIe 4.0 x4 NVMe drive that also supports PCIe 5.0 x2 on boards wired for it, which is why the listing reads “Gen 4×4 | 5×2.” For a gaming laptop, the Gen4 x4 mode is the one that matters most. Samsung rates the 2TB model at up to 7,250 MB/s sequential read and 6,300 MB/s sequential write, and its published endurance for this capacity is 1,200 TBW, well above most QLC competitors. It is a DRAM-less design that uses the host memory buffer, which is common for drives in this class and generally fine for gaming and general use.
- Capacity: 2TB
- Form factor: M.2 2280
- Interface: PCIe 4.0 x4 or 5.0 x2, NVMe 2.0
- Rated speed: up to 7,250 MB/s read, per the listing
- Endurance: 1,200 TBW at 2TB, per Samsung’s datasheet
Pros
- TLC flash and a high TBW rating suit heavy, long-term use
- Samsung’s Magician software helps with updates and monitoring
Cons
- No bundled heatsink, so check your laptop’s slot cooling
- Heavy sustained writes can fall back to slower speeds once the cache is full
Compared with the Crucial P310 2TB, it offers a substantially higher endurance rating for a similar headline speed, which makes it the better long-term pick.
Who should buy it: players who reinstall large games often, record gameplay or edit video on the same drive, and want the peace of mind of a bigger write budget. Who can skip it: anyone whose laptop only supports PCIe Gen3, since much of the Gen4 benefit will go unused, though the drive remains compatible.
Installation note: because it uses the standard 2280 length, it drops into the same screw position as the stock drive in most gaming laptops. Move any adhesive thermal pad or metal shield from the old drive to the new one, and leave the old drive in a static-safe bag until your clone or fresh install is confirmed.
2. Crucial P310 2TB (2280) – Best for Large Libraries on Gen4 Laptops
The 2280 version of the P310 is a straightforward capacity upgrade for gaming laptops. The listing quotes up to 7,100 MB/s read and 6,000 MB/s write for the 2TB model and says it works with laptops, desktops and select handheld consoles. According to published reviews, the drive pairs Micron’s 232-layer QLC flash with a Phison controller and a host memory buffer rather than DRAM, and Crucial’s rating is 440 TBW at 2TB. That makes it fast in short bursts and affordable per terabyte, but with less endurance headroom than a TLC drive.
- Capacity: 2TB
- Form factor: M.2 2280
- Interface: PCIe Gen4 x4 NVMe, backward compatible with Gen3 per the listing
- Rated speed: up to 7,100 MB/s read, 6,000 MB/s write
- Extras: Acronis data recovery software included, per the listing
Pros
- Large capacity for sprawling game libraries
- Strong rated speeds and backward compatibility with older slots
Cons
- QLC flash and a modest TBW rating limit heavy-write workloads
- Once the fast cache fills, sustained writes slow down
It is the closest match to the Samsung in capacity and speed, but the Samsung is better suited to constant rewriting, while the Crucial is a good fit for storing games that mostly sit still.
Check the listing to confirm whether a heatsink variant is included, because the name does not state it. If your laptop has a metal cover or thermal pad over the M.2 slot, that is usually enough.
Real-world note: the headline write figure applies to the fast cache, so a very large single transfer, such as copying a whole game library at once, will eventually slow once that cache fills. For normal gameplay, where most of the activity is reading installed files, this rarely becomes a problem.
3. Fanxiang 1TB Gen4 – Best for a Modest Upgrade With a Heat Spreader
Fanxiang’s 1TB drive is marketed mainly for the PS5, but the listing also positions it as an upgrade for PCs and laptops. It uses PCIe Gen4 x4 with NVMe 1.4 and advertises up to 4,800 MB/s, which is noticeably lower than the 7,000 MB/s-class figures on the other Gen4 drives here. In day-to-day gaming, loading times are often limited by the CPU and game engine rather than the last few thousand MB/s, so the gap may not matter. The listing mentions a heat-dissipation sticker, which is a thin spreader rather than a tall heatsink, so it should fit tight laptop slots more easily than a bulky cooler.
- Capacity: 1TB (the line is offered in several capacities)
- Form factor: M.2 2280
- Interface: PCIe Gen4 x4, NVMe 1.4
- Rated speed: up to 4,800 MB/s, per the listing
- Flash: 3D NAND with an SLC cache; confirm cell type on the listing
Pros
- Thin heat spreader suits low-clearance laptop slots
- Gen4 interface and a five-year service promise mentioned in the listing
Cons
- Lower advertised speed than the other Gen4 drives
- Less published detail on endurance and controller, so confirm on the product page
Next to the Crucial P310 1TB, it offers a spreader out of the box but a lower speed rating and less transparent endurance data.
Who should buy it: gamers who want an affordable 1TB step up without needing the highest peak throughput, and who value a built-in spreader. Who should skip it: anyone who needs documented endurance numbers for heavy content creation.
Keep in mind that the PS5 branding on the listing refers to console compatibility, and it does not change how the drive behaves in a laptop. The spreader sticker should also be checked against your laptop’s existing thermal pad so you do not stack two layers and lift the drive away from the contact surface.
4. Crucial P310 2TB (2230) – Best for Handhelds and Short-Slot Laptops
This is the compact version of the P310, and it does not fit a standard laptop slot. The 2230 form factor is 30mm long, versus 80mm for 2280, and the listing itself names the Steam Deck, ASUS ROG Ally and MSI Claw as targets, along with mini PCs and ultrabooks. Treat it as a runner-up for this topic: it is excellent if your gaming machine uses a 2230 slot, but a typical gaming laptop with a 2280 slot will not accept it without a physical adapter that fits the mounting screw position. Check your laptop’s service manual first.
- Capacity: 2TB
- Form factor: M.2 2230, 30mm long
- Interface: PCIe Gen4 x4 NVMe
- Rated speed: up to 7,100 MB/s read, per the listing
- Intended devices: handhelds, mini PCs and ultrabooks, per the listing
Pros
- Large 2TB capacity in a very small form factor
- Same Gen4 platform as the 2280 model
Cons
- Does not fit standard 2280 laptop slots
- Small drives have less surface area to shed heat, so keep airflow in mind
It differs from the 2280 P310 only in length, which is the entire reason to choose it or avoid it.
Who should buy it: owners of a handheld PC or a compact gaming laptop with a confirmed 2230 slot. Who should skip it: nearly everyone with a mainstream 15 to 18 inch gaming laptop, who should pick one of the 2280 drives above.
If you are unsure about your slot, look for markings printed on the board next to the screw post, which often show 2230, 2242 and 2280 positions. A laptop with only the long position cannot take this drive without an adapter, and the manufacturer of your laptop can confirm what it supports.
5. Crucial P310 1TB (2280) – Best for a First Upgrade
If your gaming laptop shipped with a 512GB drive that is already full, the 1TB P310 is a sensible step. It carries the same up to 7,100 MB/s read and 6,000 MB/s write rating as the 2TB model on the listing, and published reviews describe its endurance as 220 TBW at 1TB. That is plenty for gaming, where most of the data is read repeatedly after the initial install, but it is lower than what a TLC drive offers if you move large files daily.
- Capacity: 1TB
- Form factor: M.2 2280
- Interface: PCIe Gen4 x4 NVMe, backward compatible with Gen3
- Rated speed: up to 7,100 MB/s read, 6,000 MB/s write
- Included: Acronis data recovery software, per the listing
Pros
- Easy drop-in replacement for a small stock drive
- Same Gen4 speeds as the larger model
Cons
- 1TB fills quickly with modern AAA titles
- Lower endurance rating than TLC alternatives
The 2TB version of the same drive is the natural step up if your library is large, since the per-game cost of capacity is usually lower there.
Who should buy it: players with a handful of favorite games who want a clean, fast boot drive. Who should skip it: anyone with a library of ten or more large games, who will probably need 2TB.
Value note: if you expect your library to grow, remember that replacing a drive later means another clone or reinstall. Buying 2TB now can save that second round of work, while 1TB is a perfectly reasonable choice for a secondary laptop or a player who keeps only two or three titles installed.
6. KingSpec 2TB Gen4 – Best for the Highest Rated Read Speed
The KingSpec Championship Edition 2TB is listed with up to 7,400 MB/s read, the highest sequential figure on this page, and 3D NAND flash. Like the Fanxiang, the listing mentions the PS5, but it also names gaming PCs and laptop upgrades. KingSpec is a less widely documented brand than Samsung or Crucial, so details such as endurance, controller, DRAM or HMB design and warranty terms should be confirmed on the product page before purchase. Rated speeds on the box are sequential peaks and rarely translate directly into noticeably faster gameplay.
- Capacity: 2TB
- Form factor: M.2 2280 (confirm on the listing)
- Interface: PCIe Gen4 NVMe
- Rated speed: up to 7,400 MB/s read, per the listing
- Flash: 3D NAND; confirm cell type and endurance rating
Pros
- Highest advertised read speed among the six
- 2TB capacity for a large library
Cons
- Less documentation on endurance and controller
- Gen4 peak speeds mean more heat, so slot cooling matters
Compared with the Crucial P310 2TB, it advertises a faster peak but shares less transparent long-term data.
Who should buy it: people who want the best-looking speed sheet and are comfortable relying on the seller’s warranty. Who should skip it: buyers who prioritize a well-documented endurance rating over a headline number.
Practical tip: before committing, read the warranty and return terms on the product page, check that the capacity shown is genuinely 2TB in your operating system after installation, and keep proof of purchase. Reliable results with any lesser-known brand start with documented support.

How We Chose These
This guide is built from research and published specifications. We began with the drives shown in current catalog listings, then compared each one’s capacity, form factor, interface, rated speeds and any published endurance data from manufacturer pages and independent hardware reviews. We prioritized drives that fit the standard 2280 slot most gaming laptops use, flagged the 2230 model plainly as a niche option, and noted when a listing did not state a spec instead of guessing. Rated speeds are manufacturer maximums, so we treated them as a rough ranking tool rather than a promise of real-world results.
What to Look For
Check the slot: length, key and interface
Almost every gaming laptop uses a 2280 slot, meaning 22mm wide and 80mm long, with an M key connector for NVMe drives. Some compact laptops and handhelds use 2230 or 2242, and some thin models have a single slot that is already occupied by the stock drive. Look up your model’s service manual or the manufacturer’s upgrade page. Also confirm that the slot supports PCIe NVMe rather than only SATA. A PCIe Gen4 drive will still work in a Gen3 slot, but it will run at Gen3 speeds, around 3,500 MB/s at best.
Capacity: how much storage do you actually need?
Modern AAA titles frequently take 80 to 150GB. A rule of thumb: add the sizes of the games you play regularly, add around 150GB for Windows and apps, then add 15 to 20 percent free space to keep write speeds healthy. For example, eight installs averaging 90GB come to about 720GB, plus 150GB for the system, which is roughly 870GB; add the free space buffer and you land above 1TB, making 2TB the safer choice. The jump from 1TB to 2TB often costs less per gigabyte, which is why many gamers skip 1TB entirely.
TLC, QLC, cache and DRAM-less designs
TLC stores three bits per cell and generally offers higher endurance and steadier sustained writes. QLC stores four bits per cell, which increases capacity per chip but reduces endurance and slows once the fast cache is exhausted. Many current drives omit DRAM and borrow a small slice of system memory through the host memory buffer, which works well for gaming but can slow down in prolonged heavy writes. For a laptop used mostly to play games that are installed once and read many times, either design works. If you capture video or move large project files daily, favor TLC and a higher TBW rating.
Heat, heatsinks and clearance
Gen4 drives can throttle if they run hot. Laptops usually have limited room, so a tall heatsink may not fit under the bottom cover. A thin graphite sticker or a flat spreader is a safer choice if the manufacturer did not include a thermal pad. Many laptops already have a metal shield over the stock drive, and you should move it to the new one. Never block the laptop’s vents during installation or use, and follow the manufacturer’s guidance when opening the case.
Migration, safety and warranty
Back up your data before opening the laptop. Power it off, unplug the charger, and discharge static by touching a grounded metal surface. Cloning software lets you copy the old drive to the new one, or you can perform a clean install and re-download games from your launcher. Keep the old drive as a backup until you have verified everything works, and register the new one so the warranty clock is documented.
Questions
Will a Gen4 drive work in a laptop that only supports Gen3?
Yes, PCIe is backward compatible, so a Gen4 NVMe drive works in a Gen3 slot. It will simply run at the slower Gen3 limit, so you may prefer a less expensive Gen3 drive if you are certain the slot will not change.
Do faster read speeds improve gaming?
They can shorten the first load of a level, but for most games the CPU, GPU and game design set the pace. The difference between a 5,000 MB/s and a 7,000 MB/s drive is often hard to notice in play, so capacity and endurance deserve at least equal weight.
Is QLC fine for a gaming laptop?
For most players, yes. Games are read far more than they are written, and QLC drives with a healthy TBW rating will last through typical use. If you write large files daily, a TLC drive gives more headroom.
Can I use a 2230 drive in a 2280 slot?
Not directly. The drive is shorter, and the mounting screw sits at a different position. Some adapter brackets exist, but they add a point of failure, so confirm your laptop’s slot size and buy the matching form factor.
Do I need a heatsink?
Many laptops already cool the drive with a thermal pad and metal shield, which is generally enough. A bulky heatsink can prevent the bottom cover from closing, so choose a flat spreader unless your laptop has clear space.
How do I move my games to the new drive?
You can clone the old drive with imaging software, or install Windows fresh and add your game launcher libraries back. Cloning preserves your setup, while a clean install is a good moment to remove clutter.
