Best Big Spring Sale 4TB SSD Deals on Amazon in 2026

1. WD_Black SN7100 4TB NVMe SSD – Gen4 PCIe Gaming Drive

I installed the WD_Black SN7100 in my gaming laptop last month, and the difference was immediately noticeable. Boot times dropped from 45 seconds to under 12, and game loads that used to keep me staring at loading screens now happen in a blink. The 7,000 MB/s read speeds put it right alongside the Samsung 990 Pro in real-world performance, but at a significantly lower price point during this sale.

What surprised me most was how cool this drive runs. During extended gaming sessions, I never saw temperatures climb above 60 degrees Celsius without any aftermarket heatsink. The TLC NAND flash is a major advantage over QLC alternatives in this price range, offering better endurance and sustained write performance. With a 2,400 TBW rating, you could write 1.3 TB per day for five years before hitting the warranty limit.

The power efficiency is genuinely impressive. WD claims 100% improvement over the previous generation, and my laptop battery definitely noticed the upgrade. Handheld gamers using devices like the Steam Deck or ROG Ally will appreciate this efficiency, as it translates to longer play sessions away from the charger.

Perfect for Gaming and Laptops

This drive excels in portable gaming setups where thermal headroom is limited. The Gen4 interface delivers flagship-tier performance without the thermal baggage that typically comes with high-speed NVMe drives. If you’re building a gaming PC or upgrading a laptop, the SN7100 offers the best balance of speed, efficiency, and value in the 4TB category.

Thermal Performance Considerations

Under sustained heavy loads like transferring 64GB files repeatedly, you may notice some thermal throttling. The drive recovers quickly, but users doing constant large file transfers should consider adding a heatsink. For typical gaming and general use, this will never be an issue.

One minor annoyance is that WD’s Dashboard software (Kitfox) doesn’t fully recognize the drive yet for firmware updates. This should be resolved with future software updates, but it’s worth noting if you like keeping your firmware current.

2. Samsung 990 EVO Plus 4TB SSD – PCIe Gen 4×4/Gen 5×2

The Samsung 990 EVO Plus hits that rare sweet spot between performance and price that makes it our value pick. Samsung is the world’s leading flash memory manufacturer for good reason, and this drive showcases their engineering prowess. The 7,250 MB/s read speeds match or exceed many premium competitors while costing significantly less during the Big Spring Sale.

I’ve been using this drive as my primary boot drive for three weeks now. The nickel-coated controller keeps temperatures manageable even without a dedicated heatsink, though sustained workloads will benefit from additional cooling. The Intelligent TurboWrite 2.0 technology maintains high write speeds even when working with large files, a noticeable improvement over the original EVO series.

The hybrid PCIe interface is clever engineering. It works with both PCIe 4.0 x4 and PCIe 5.0 x2 configurations, making it compatible with current systems while offering an upgrade path for next-gen motherboards. Backward compatibility with PCIe 3.0 means this drive works in older systems too, though you won’t see the full speed potential.

Why This Is Our Value Pick

Samsung’s reputation for reliability matters when you’re trusting a drive with 4TB of data. The 990 EVO Plus carries the Samsung Magician software suite for drive monitoring, firmware updates, and performance optimization. With over 6,000 reviews and a 4.8-star rating, the community has validated this as a dependable choice. The five-year warranty provides additional peace of mind.

DRAM-Less Design Trade-offs

The DRAM-less architecture keeps costs down but does impact sustained random write performance compared to the PRO series. Most users won’t notice this during gaming or general computing, but content creators doing constant small file operations might prefer a drive with DRAM cache. For the majority of users, the value proposition here is exceptional.

Samsung’s HMB (Host Memory Buffer) technology partially compensates for the lack of DRAM by using system RAM for mapping tables. In practice, this works well for desktop systems with ample memory.

3. Samsung 990 PRO 4TB SSD – PCIe 4.0 Flagship Performance

The Samsung 990 PRO remains the benchmark against which all other PCIe 4.0 drives are measured. With sequential read speeds hitting 7,450 MB/s and writes at 6,900 MB/s, this is essentially maxing out what the Gen4 interface can deliver. The 55% improvement in random performance over the 980 PRO translates to noticeably snappier system responsiveness.

I tested this drive in both a high-end gaming rig and a PS5, and the results were impressive in both scenarios. Game load times in titles like Cyberpunk 2077 and Red Dead Redemption 2 dropped significantly compared to my previous NVMe drive. The DRAM cache ensures consistent performance even during heavy multitasking, something budget drives often struggle with.

For PS5 owners, the 990 PRO is one of the officially recommended expansion drives. The heatsink model (sold separately or bundled) is essential for console use, as Sony requires thermal management for warranty compliance. The drive automatically enables Game Mode on PS5 for optimized performance.

Who Should Choose the 990 PRO

Professionals and enthusiasts who want the absolute best PCIe 4.0 performance without jumping to Gen5 should consider this drive. The 17,000+ reviews and consistent 4.7-star rating speak to Samsung’s quality control. If you edit video, work with large datasets, or simply want your system to feel as fast as possible, the 990 PRO delivers.

Low Stock Warning

At the time of writing, only six units remain in stock. The 990 PRO 4TB has been in high demand since launch, and stock issues are common. If you see this at a good price, don’t hesitate. The drive is not Prime eligible currently, which may affect delivery timing.

For sustained high-performance workloads, a heatsink is mandatory. Without one, thermal throttling will kick in during extended writes, dropping speeds significantly. Samsung sells an official heatsink version, or you can use third-party M.2 heatsinks.

4. Crucial T710 PCIe Gen5 4TB SSD – Cutting-Edge Speed

The Crucial T710 represents the bleeding edge of SSD technology with PCIe Gen5 performance reaching 14,900 MB/s sequential reads. That’s more than double the speed of even the fastest Gen4 drives. For users with compatible motherboards, this drive eliminates storage as a bottleneck entirely.

Installing this in my Intel 14th Gen test system, file transfers that previously took minutes now complete in seconds. Large video projects that used to bottleneck on storage speed now flow smoothly. The Micron G9 TLC NAND provides the reliability Crucial is known for, and the included one-month Adobe Creative Cloud subscription is a nice bonus for creators.

The value proposition here is remarkable. PCIe Gen5 drives typically command a significant premium, but the T710 brings this cutting-edge performance closer to Gen4 pricing. For early adopters building high-end systems, this is the most cost-effective way to experience Gen5 speeds.

Future-Proof PCIe Gen5 Performance

If you’re building a system with an Intel 13th/14th Gen or AMD Ryzen 7000 series processor, the T710 is optimized for these platforms. The AES-256 hardware encryption with TCG Opal 2.01+ support makes this suitable for professional environments where data security matters.

The WD Blue SN5000 occupies a sensible middle ground in the 4TB SSD market. With 5,500 MB/s read speeds, it’s fast enough for virtually any use case while costing significantly less than flagship drives. The 49% discount during the Big Spring Sale makes this an attractive option for bulk storage expansion.

I’ve been using this drive as secondary storage in my workstation for game libraries and project files. The nCache 4.0 technology provides surprisingly good sustained write performance for a mid-range drive. While it won’t match the 7,000+ MB/s speeds of premium options, the real-world difference is negligible for most tasks.

The lower operating temperatures compared to flagship drives make this an excellent choice for systems with limited cooling. It also works well in USB-C enclosures for fast external storage, something I’ve tested with Thunderbolt 4 enclosures for portable video editing.

Great for Secondary Storage

Not every drive needs to be your boot drive. The SN5000 excels as a secondary storage solution where you need capacity and reliability without paying for maximum speed. Game libraries, media collections, and project archives are perfect use cases. The 1,200 TBW endurance rating is sufficient for typical consumer workloads.

QLC NAND Trade-offs

The QLC NAND flash stores four bits per cell versus three in TLC, which reduces cost but also endurance. For write-heavy workloads like constant video recording or frequent large file transfers, a TLC drive would be a better choice. However, for read-heavy usage like gaming or media playback, QLC performs admirably.

Note that this drive doesn’t meet Sony’s speed requirements for PS5 expansion. For console use, look at drives with 5,500 MB/s minimum sustained performance, preferably with TLC NAND.

6. Crucial P310 4TB PS5 SSD with Heatsink – Budget Gaming Pick

The Crucial P310 with heatsink is purpose-built for PS5 expansion, and it shows. Installation took me about five minutes with just a screwdriver, and the console recognized the drive immediately. With 7,100 MB/s read speeds and 6,000 MB/s writes, it exceeds Sony’s requirements while costing less than Samsung’s PS5-validated options.

After loading about 2TB of games onto this drive, load times are virtually indistinguishable from the internal SSD. The included heatsink is low-profile enough to fit in the PS5’s expansion slot without any modification. During extended gaming sessions, temperatures stayed well within safe limits.

Crucial’s Micron G8 NAND provides the reliability PlayStation owners need when trusting a drive with their game library. The five-year warranty is reassuring for a budget-oriented drive. Compatibility extends beyond PS5 to laptops and desktops, making this a versatile upgrade.

PS5 Expansion Made Easy

Sony’s M.2 expansion slot requirements are specific: Gen4 PCIe, minimum 5,500 MB/s sustained reads, and a heatsink. The P310 checks all boxes and then some. The straightforward installation process makes this accessible even for users who have never opened their console before.

Who Should Consider This Drive

PS5 owners needing more storage without paying Samsung premium prices will find the P310 hits the sweet spot. Laptop users looking for a fast boot drive also benefit from the included thermal management. The only caveat is checking stock, as availability has been limited due to high demand.

Some early buyers reported missing mounting screws in their packages, so have a spare M2 screw handy just in case. This seems to be a packaging issue rather than a product defect.

7. SanDisk Extreme 4TB Portable SSD – Rugged External Storage

The SanDisk Extreme 4TB is the portable SSD I reach for when traveling with my camera gear. The 1,050 MB/s transfer speeds mean I can offload hundreds of RAW photos and 4K video clips in minutes rather than hours. The IP65 water and dust resistance has saved my data more than once during outdoor shoots.
