This drive reads at 7,450 MB/s — that is nearly 50% more headroom for sequential transfers than the Crucial E100 (5,000 MB/s) — and keeps temperatures low during 4K video work.

You get read speeds of 7,450 MB/s and write speeds of 6,900 MB/s for 4K video editing or high-end gaming, without stepping up to a Gen 5 platform. The integrated heatsink and Dynamic Thermal Guard technology keep temperatures in check, so you do not lose performance during long file transfers. Reviewers consistently call it fast, reliable, and easy to install — one reviewer noted it “operates at lower temp even when running maxed out.”

It also has a rated endurance of up to 1,200 TB total bytes written (TBW), which means you could write 200 GB of data every day for over 16 years before wearing it out. The free Samsung Magician software makes it simple to monitor drive health and keep firmware updated. Unlike the Crucial E100 which reads at 5,000 MB/s, the 990 PRO gives you nearly 50% more headroom for sequential transfers.

At 6,000 MB/s read, this Gen 4 drive is 20% faster than the Crucial E100 (5,000 MB/s) and costs less than premium Gen 4 options.

Read speeds up to 6,000 MB/s make booting and game loading nearly instant. It uses a Gen 4×4 NVMe interface and supports capacities up to 4TB, so you can scale up later. Buyers mention it is “fast as advertised” with “no gaming stutter” and one buyer mentioned “over 1,300 MB/s read on an old laptop, faster on modern systems.” That means even if you upgrade your motherboard later, this drive will accelerate with it.

At 20% faster than the Crucial E100 (5,000 MB/s vs 6,000 MB/s), the NV3 delivers noticeable gains for tasks like transferring large video files or launching simulation games. It is also shock resistant, adding a layer of durability for laptop users. Just keep in mind that it does not include a heatsink, so if your motherboard lacks one, you might want to add a basic thermal pad for sustained workloads.

The manufacturer claims this 5,000 MB/s drive is 8 times faster than a SATA SSD and 33 times faster than a hard drive — a massive real-world upgrade for older systems.

At 5,000 MB/s read speeds, the Crucial E100 is 8 times faster than a SATA SSD (which reads at about 550 MB/s) and 33 times faster than a traditional hard drive, according to the manufacturer. That is a huge real-world difference for anyone upgrading from an older system. One buyer summed it up perfectly: “It is significantly faster than what I was using before (an HDD), and it works perfectly.” The 2TB capacity gives you room for dozens of modern games or a full photo and video library.

Installation is straightforward — the drive comes with step-by-step instructions for cloning your old drive, so you can migrate your operating system without reinstalling everything. It is also quieter and cooler than a hard drive. While it does not match the 6,000 MB/s or 7,450 MB/s speeds of the picks above, the E100 delivers the most noticeable upgrade — from slow to fast — for the lowest entry price in this roundup.

This budget Gen 4 drive (5,200 MB/s read, 4,700 MB/s write) comes with a screwdriver and a 5-year warranty — a rare combo at this price.

At 5,200 MB/s read and 4,700 MB/s write speeds, the Fikwot FX660 is built for gamers who want to expand their console storage without spending top dollar. It explicitly supports the PS5, and one buyer confirmed it “works great on my PS5” while another said it “stores all of my games with plenty of room left over!” The package includes a screwdriver and screws, which makes installation simpler than most drives.

It uses a graphene heat dissipation sticker instead of a traditional heatsink, designed to keep temperatures down without adding bulk. The drive also has two intelligent management systems — Auto-Adaptive Temperature Regulation and Power Efficiency Management — that help control power consumption and heat. While its read speed is slightly below the Crucial E100 (5,200 MB/s vs 5,000 MB/s, basically a wash), it offers a competitive write speed that benefits game level loading.

The fastest drive here (14,900 MB/s read, 14,000 MB/s write) — one buyer benchmarked it at about double the speed of the previous-gen SN850X.

With sequential read speeds up to 14,900 MB/s and write speeds up to 14,000 MB/s (for the 2TB model), the WD_Black SN8100 is the fastest drive in this lineup. It is designed for AI applications, gaming, and video editing, and one buyer benchmarked it at “~10,500 MB/s write, ~10,200 MB/s read” on a Ryzen 9 7950X system, calling it “double SN850X speed.” Another reviewer noted a “65GB Windows 11 backup image now completes in 45 seconds” on the comparable SABRENT Rocket 5, and the SN8100 is even faster on paper.

The drive also claims over 100% more power efficiency than WD’s previous Gen 4 drive, averaging under 7.5W of power. That means you get these massive speeds without overheating your laptop or desktop. It uses TLC 3D CBA NAND for reliability and comes with the SANDISK Dashboard software for monitoring. The catch is that you will need a PCIe 5.0 motherboard to see those speeds — otherwise it will run at Gen 4 rates.

It delivers reads of 14 GB/s with DirectStorage-optimized firmware — one owner reported a “65GB Windows 11 backup image now completes in 45 seconds.”

The SABRENT Rocket 5 delivers transfer speeds up to an astounding 14 GB/s, making it a natural pick for creative professionals who move massive project files. It uses DirectStorage-optimized firmware to reduce game load times and improve asset streaming in compatible titles. One reviewer called it “the best SSD in market especially in gaming PC” and another said a “65GB Windows 11 backup image now completes in 45 seconds,” which gives you a real-world sense of how much time this drive saves.

The drive is backward compatible, so it works in a PCIe 4.0 slot, but you will only see those full Gen 5 numbers in a Gen 5 slot. SABRENT also sells a separate high-end heatsink with dual heatpipes, which is worth considering since this drive can run warm under sustained load. It works with Windows, macOS, and Linux, making it a versatile choice for multi-platform users.

It matches the Samsung 990 PRO’s endurance (1,200 TBW) but adds Gen 5 speed (10,000 MB/s read) — just budget for a heatsink, because it runs hot.

The Corsair MP700 Elite reads at up to 10,000 MB/s and writes at up to 8,500 MB/s, placing it solidly in the Gen 5 performance tier but at a slightly lower price point than the WD_Black SN8100. It uses high-density 3D TLC NAND, which gives it an endurance rating of up to 1,200 TBW, matching the Samsung 990 PRO’s longevity. One reviewer benchmarked it and noted sequential reads of 10,301 MB/s and writes of 9,054 MB/s in CrystalDiskMark, calling it “30% faster than fast v4” drives.

The drive supports Microsoft DirectStorage, which lets it talk directly to your graphics card for faster game loading in compatible titles. A buyer described it as “a thermal nuke strapped to a rocket,” meaning it runs hot — a heatsink or active cooler is strongly recommended for sustained heavy use. That is the trade-off for Gen 5 speed: you need to manage the heat to keep performance steady.
