The KingSpec XG7000 beats Solidigm's flagship P44 Pro on sequential read speed (7,400 MB/s vs 7,000 MB/s) and ties it on endurance, at roughly half the price per drive.
This guide compares KingSpec against Solidigm, the SK hynix-owned brand built from Intel's former SSD business, on the specs that actually decide a purchase.
Key Takeaways:
- The KingSpec XG7000 edges out Solidigm's P44 Pro on sequential read speed and ties it on write speed at the 2TB tier.
- Both drives hit the same 1,200TB endurance rating at 2TB, but the P44 Pro launched at $219.99 for that capacity versus KingSpec's far lower price point.
- Solidigm's P44 Pro posts much higher random IOPS, a real advantage for heavy multitasking workloads, and carries a longer 5-year warranty versus KingSpec's 3 years.
- KingSpec's budget NX Series actually out-endures Solidigm's budget P41 Plus, because the P41 Plus uses lower-endurance QLC NAND.
- KingSpec's XG7000 lineup scales to 8TB in one drive, more than most Solidigm consumer listings offer.
KingSpec XG7000 vs Solidigm P44 Pro Head to Head
Solidigm is the SK hynix-owned SSD brand formed from Intel's former NAND and SSD business, so its drives carry serious pedigree. The P44 Pro is its consumer flagship, and it's the fairest match for KingSpec's XG7000 since both are PCIe 4.0 NVMe drives aimed at gaming PCs and creative workstations.

Where KingSpec Pulls Ahead
Solidigm's engineering pedigree is real, but KingSpec still wins on the factors that matter most for a typical build: top-line speed, endurance per dollar, and how much capacity you can get in one drive.
Faster on the Number Buyers Actually Compare
The XG7000's 7,400 MB/s sequential read rating beats the P44 Pro's 7,000 MB/s, and both tie at 6,500 to 6,600 MB/s sequential write on their larger capacities.
Sequential speed is what drives game load times, file transfers, and video exports, the everyday tasks most buyers actually notice.
Matching Endurance at a Fraction of the Price
Both drives are rated for 1,200TB written at the 2TB capacity, so KingSpec isn't trading durability for a lower price tag. The P44 Pro launched at $219.99 for 2TB, well above what KingSpec charges for its 512GB XG7000, and KingSpec's price advantage typically holds across capacities.
KingSpec's Budget Line Beats Solidigm's Budget Line on Endurance
Solidigm's entry-level P41 Plus uses QLC NAND to hit its low price, and QLC stores more data per cell at the cost of endurance.
At 1TB, the P41 Plus is rated for 400TB written. KingSpec's NX Series at 1TB is rated for 500TB written, a meaningful durability edge, even though the NX Series runs on the older PCIe 3.0 interface.
More Room to Grow
The XG7000 scales up to 8TB in a single M.2 2280 drive. Solidigm's P44 Pro is most commonly found in 512GB, 1TB, and 2TB retail listings.
For large media libraries or multi-project creative work, KingSpec's ceiling gives you more room without adding a second drive.
Where Solidigm Still Has an Edge
A fair comparison means naming where Solidigm wins too. The P44 Pro's random IOPS numbers are genuinely strong, reaching up to 1,400K read and 1,300K write at 1TB and 2TB, well ahead of the XG7000's 710K and 670K.
If your workload is heavy multitasking, running a database, or juggling huge numbers of small files, that gap will show up.
Solidigm also backs its consumer drives with a 5-year warranty, two years longer than KingSpec's 3-year term.
And Solidigm's pedigree carries real weight: it inherited Intel's SSD engineering team and NAND technology when SK hynix completed the acquisition, so the P44 Pro benefits from that background.
Weigh that against the price gap. A shorter warranty matters less when the drive itself costs significantly less to replace.
Which Drive Fits Your Build
The right pick depends on your workload, not just which brand sounds more established.
- Gaming PC or PS5 upgrade: The XG7000 matches the sequential speed that matters for load times and installs, at a lower buy-in than the P44 Pro.
- Video editing or content creation: KingSpec's 8TB ceiling and matching sequential throughput make it a practical single-drive option for large project files.
- Budget build or OS drive: The KingSpec NX Series outlasts Solidigm's P41 Plus on paper endurance, so it's the safer pick if you plan to keep the drive for years.
- Database work, heavy multitasking, or a workstation that leans on random IOPS: Solidigm's P44 Pro is the stronger technical choice for that specific workload.

Shop NX SeriesPractical Tips Before You Buy
- Check whether a listing is TLC or QLC NAND. QLC drives are usually cheaper but wear out sooner under heavy write workloads.
- Confirm your motherboard or console supports PCIe 4.0 before paying extra for it. PCIe 4.0 drives still work in PCIe 3.0 slots, just at PCIe 3.0 speeds.
- Match capacity to your actual workload. A 1TB or 2TB XG7000 covers most gaming and creative setups without paying for 8TB you won't use.
- If random IOPS matter for your use case, such as running databases or virtual machines, weigh that against KingSpec's price advantage before deciding.
Common Mistakes When Comparing SSDs
A few patterns trip up buyers comparing KingSpec and Solidigm, or any two SSD brands:
- Assuming a longer corporate history means a better drive today. Solidigm's Intel pedigree is real, but KingSpec's XG7000 matches or beats its sequential speed and 2TB endurance rating at a lower price.
- Ignoring NAND type on budget drives. Solidigm's P41 Plus uses QLC NAND with lower endurance than KingSpec's TLC-based NX Series at the same capacities.
- Overpaying for random IOPS you won't use. Solidigm's higher IOPS numbers matter for specific workloads like databases and heavy multitasking, not for typical gaming or file transfer use.
- Skipping the warranty terms. A shorter warranty isn't automatically a dealbreaker, but know the number before you buy, not after something fails.
Frequently Asked Questions
Is KingSpec a Good SSD Brand Compared to Solidigm
Yes. KingSpec, operated by Shenzhen KingSpec Electronics Technology Co., Ltd, has manufactured storage products since 2007 and runs its own production facility producing around 12 million units annually. Its XG7000 series matches or beats Solidigm's P44 Pro on sequential speed and 2TB endurance rating, at a significantly lower price. Every KingSpec SSD ships with a 3-year warranty.
Is the Solidigm P44 Pro Faster Than the KingSpec XG7000
Not on sequential speed. The XG7000 is rated up to 7,400 MB/s read versus the P44 Pro's 7,000 MB/s, and both tie around 6,500 to 6,600 MB/s write on larger capacities. Solidigm pulls ahead on random IOPS, which matters more for database work and heavy multitasking than for everyday file transfers and gaming.
Is Solidigm the Same Company as Intel
Not anymore. Solidigm was created when SK hynix acquired Intel's NAND memory and SSD business, completing the deal in stages starting in late 2021. Solidigm now operates as an independent, SK hynix-owned brand, carrying forward much of the engineering and NAND technology from Intel's former SSD division.
Is QLC NAND Less Durable Than TLC NAND
Generally, yes. QLC NAND stores four bits per memory cell instead of three, which lowers cost but reduces how many write cycles the drive can handle before wearing out. That shows up directly in endurance ratings. Solidigm's QLC-based P41 Plus is rated for 400TB written at 1TB, while KingSpec's TLC-based NX Series at 1TB is rated for 500TB written.
Which Is Better Value, KingSpec or Solidigm
KingSpec generally offers better value per gigabyte. Its XG7000 matches Solidigm's P44 Pro on sequential speed and ties its 2TB endurance rating, while launching at a significantly lower price across comparable capacities. Solidigm remains the stronger pick if your workload specifically benefits from higher random IOPS or you want a longer warranty term.
Final Takeaways
Choosing between KingSpec and Solidigm comes down to what your build actually needs.
If you want flagship-level sequential speed, matching endurance, and capacity options up to 8TB without paying Solidigm's price premium, the KingSpec XG7000 is the practical choice for most gaming, PS5, and content creation builds.
