SSD pricing in 2026 finally hit the level where every PC should have at least 1TB of NVMe sitting in an M.2 slot. Gen4 drives that cost $300+ two years ago now sell at $120/TB or less, and it’s because TLC and QLC NAND fabs caught up to demand right when crypto miners stopped hoarding storage. The result? Genuine bargains, not the fake “was $500, now $499” nonsense you’ll see on Black Friday landing pages. These are the four drives we’d actually buy right now if we were spec’ing a build this quarter, sorted by what job you need the drive to do.
TL;DR – the deal in one line
WD_Black SN7100 2TB at $243 is the value play and what most builders should grab. Samsung 990 PRO 2TB at $370 is the premium pick if you’ve got headroom in the budget and care about sustained writes. The fanxiang 2TB with pre-mounted heatsink covers PS5 console upgrades, and the fanxiang S101 250GB SATA handles boot-drive or secondary-storage duty for under fifty bucks. Four drives, four jobs, no overlap.
What you get
The WD_Black SN7100 2TB runs Gen4 x4 at 7,250 MB/s read with a 5-year warranty and stays cool without a heatsink, which matters if your motherboard’s M.2 slot sits under the GPU. WD’s controller sips power compared to last-gen SN850X, so laptops love it too.
The Samsung 990 PRO 2TB pushes 7,450 MB/s read but the real story is sustained writes and the 1,200 TBW endurance rating, roughly double what budget Gen4 drives offer. Samsung Magician software lets you monitor health and toggle performance modes, and the V-NAND is Samsung’s own silicon.
The fanxiang PS5-ready 2TB ships with a pre-mounted heatsink that meets Sony’s 8mm height limit, so it drops into the console’s expansion bay without you sourcing a thermal solution. Read speeds hit 7,100 MB/s, well past Sony’s 5,500 MB/s minimum.
The fanxiang S101 250GB SATA is the cheap insurance policy: 500 MB/s, 2.5″ form factor, perfect as a boot drive on an older rig or a Steam library overflow disk on a newer one.
Pros
- TLC NAND over QLC means more program-erase cycles before cell degradation at this capacity
- SLC cache layer smooths burst write performance for typical desktop and laptop workloads
- 2.5" SATA fits any system that previously ran a mechanical drive, zero compatibility guesswork
- Bundled cloning software removes the friction from HDD-to-SSD migrations without third-party tools
Cons
- SATA III ceiling of roughly 550MB/s sequential read caps real-world throughput well below NVMe options
- No heatsink or SATA data cable included, budget for a cable if your system lacks spares
The fanxiang S101 is a budget-tier 2.5" SATA III SSD targeting users upgrading from mechanical hard drives in older laptops, pre-built desktops, or any system without an available M.2 slot. It ships in capacities from 128GB to 4TB and uses 3D NAND TLC, which is a meaningful spec at this price band compared to cheaper QLC drives.
The defining feature here is straightforward SATA III compatibility paired with TLC NAND. Sequential read reaches 500MB/s per spec, which saturates the SATA III 6Gb/s bus. In practice, that means OS boot times drop significantly versus a spinning disk, and everyday file operations feel responsive. SSD drives in this tier typically sustain cache-assisted writes well for workloads involving files under a few gigabytes.
The honest trade-off is the interface itself. SATA III tops out around 550MB/s sequential read across all vendors, so this drive cannot compete with NVMe PCIe Gen 3 or Gen 4 options on throughput-sensitive tasks like large game asset loading or video editing scratch disk use. No DRAM cache status is specified in source data, which is typical at this tier and can affect sustained write consistency under heavy sequential workloads.
Buy this if you are replacing a dead or slow HDD in a laptop or older desktop that lacks an M.2 slot. Skip this if your system already has an open M.2 slot, where a budget NVMe drive delivers two to four times the sequential throughput for a comparable outlay.
Sequential Speed: Rated sequential read reaches 500MB/s over SATA III 6Gb/s, which effectively saturates the interface ceiling of roughly 550MB/s. Write speed is not specified in source data for the 250GB capacity. Buyers should treat published read figures as the upper bound under ideal queue-depth conditions.
NAND & Endurance: The S101 uses 3D NAND TLC cells with an SLC write cache layer. TLC at 3D stacking provides better endurance than QLC alternatives common at this tier. Exact TBW endurance figures are not specified in source data for the 250GB variant, so long-term write-heavy workloads cannot be quantitatively evaluated from available specs.
Form Factor & Interface: The 2.5" SATA III form factor installs in any system with a SATA port, including laptops using a 9.5mm or 7mm bay. No M.2 slot or adapter is required. Note that no SATA data cable is included in the box, so verify your system has a spare cable before ordering.
Warranty & Tooling: fanxiang covers this drive with a 3-year warranty. The FANXIANG SSD Toolbox provides health monitoring, disk cloning, and system migration, which reduces setup friction compared to drives that ship with no companion software.
Why these prices are actually good
Context matters when a vendor screams “deal.” The WD_Black SN850X 2TB launched at $290 back in 2023 and held that price for most of its first year. The SN7100 at $243 isn’t just cheaper, it’s faster on most desktop workloads because the controller’s newer and the NAND’s denser. You’re getting a 2025-gen drive at below 2023 launch pricing, which is the kind of math that doesn’t usually work in our favor.
Samsung 990 PRO tells a similar story. The 1TB version MSRP’d at $230 when it dropped in late 2022. Today’s 2TB at $370 works out to roughly $185 per terabyte, which undercuts the original 1TB launch price on a per-gig basis. That’s a premium drive at midrange pricing.
The driver behind all of this is straightforward: NAND oversupply. Fab capacity expanded through 2024 and 2025, demand from datacenter buyers softened slightly, and consumer SSDs caught the spillover. It won’t last forever. Memory cycles always swing back.
The catch (if any)
Nothing here’s perfect. The WD SN7100 uses TLC NAND with a smaller SLC cache than the SN850X, so if you’re shuffling 500GB Blu-ray rips or doing heavy video work, sustained write speeds drop noticeably after the first ~100GB. For gaming and general desktop use you’ll never notice. For sustained creative workloads, the 990 PRO is the safer call.
Fanxiang isn’t a Tier-1 brand and that’s worth saying out loud. Warranty support runs slower than Samsung or WD, and if a drive fails out of box you’re dealing with email chains rather than a phone line. That said, the products themselves perform well, the customer review counts back it up, and the failure rates we’ve seen aren’t out of line with bigger names.
One more PS5 caveat: that fanxiang heatsink is fixed. You can’t pull it off if your motherboard has its own M.2 cooler. It’s a PS5 drive, or it’s a PC drive in a case with vertical clearance.
Where to grab it
Amazon US has the lowest pricing we’ve tracked on both the WD_Black SN7100 and the Samsung 990 PRO, and stock’s been steady. Newegg occasionally matches Amazon on the fanxiang PS5 SSD during weekend flash sales, so it’s worth a quick price check if you’re not in a rush. Best Buy bundles WD drives with prebuilt PCs but rarely discounts them solo, so skip it for standalone purchases. Prime Day in October’s the next likely window for another price dip, but waiting four months to save $20 isn’t always the right call if your current drive’s full.
