Samsung’s cutting-edge SSD is getting another trim at the checkout, this time eyeing up the larger 4TB model rather than its slimmer brethren. If you’ve been waiting to jump aboard the PCIe 5.0 train without paying an arm and a leg, now’s your chance as the flagship Samsung 9100 Pro 4TB delivers uncompromising speed and endurance for high-performance desktops, content creators, and storage-hungry gamers.
At 17% off, this is the lowest price we’ve seen on 9100 Pro 4TB so far. It’s currently down to $475 in the US (a $95 saving on the heatsink edition), £392 in the UK, and as low as €458 across Europe. With pricing like that, it’s hard not to recommend pulling the trigger sooner rather than later, especially given the usual cost of entry into PCIe Gen 5 territory.

Samsung 9100 Pro (4TB)
“Delivering class-leading speed in a small package, Samsung’s 9100 Pro SSD makes a big splash following its long-awaited debut.” Read our review.
Built around the refined 5nm Presto controller and Samsung’s latest V-NAND, 9100 Pro is a step above the previous Pascal models, taking full advantage of the PCIe 5.0 x4 interface to deliver read speeds up to 14,800MB/s and writes around 13,400MB/s. Importantly, it delivers these numbers with outstanding consistency, thanks in part to its onboard DRAM cache and surprisingly cool thermal behaviour.
In our in-depth review, we praised its composure under pressure, noting how it maintains sustained write speeds without falling victim to throttling – a common pitfall in many Gen 5 models. We also highlighted its power efficiency, making it a well-rounded performer whether you’re gaming, rendering, or juggling large-scale transfers. It earned a four-star rating and a Club386 Recommended badge for good reason.
The 4TB capacity offers plenty of headroom for future-proofing, whether you’re managing massive media libraries or want a single, blazing-fast primary drive. And with a five-year warranty in tow, there’s peace of mind alongside the raw performance.
Not everyone needs cutting-edge PCIe 5.0 speeds, and if you’re more interested in capacity-per-quid than chasing benchmarks, Crucial P310 4TB is absolutely worth a look. It’s currently down to just $260 on Amazon US, thanks to a 22% ($74) discount, marking the lowest price this Gen 4 SSD has hit to date.

Crucial P310 (4TB)
This SSD sits near the limit of what Gen 4 M.2 slots are capable of, making for a great all-around storage solution that doesn’t break the bank.
While it doesn’t compete with the likes of Samsung 9100 PRO in raw bandwidth, P310 still delivers solid PCIe 4.0 performance with read speeds up to 7,100MB/s and writes around 6,000MB/s. That’s plenty for gaming, day-to-day use, and even moderate creative workloads.
It forgoes DRAM to keep costs down, instead leaning on your PC’s primary memory as a host memory buffer (HMB) and a Phison PS5027-E27T controller to keep things snappy in most real-world tasks. You won’t find groundbreaking consistency under heavy load, but for general use and bulk storage, the P310 gets the job done with minimal fuss.
Thermals are manageable, power efficiency is respectable, and Crucial’s proven track record in the SSD space gives it added peace of mind. Plus, you can’t ask for much more at this price.
