Intel SSD 660p (PCIe 3.0 NVMe/1,800 MB/s Read/QLC/Intel-Heritage Budget Classic) Review
The Intel SSD 660p was one of the first mainstream consumer QLC NVMe drives, using Intel's own 3D NAND to bring per-gigabyte pricing down before the QLC-based drives common today became standard practice.
It's since been succeeded by the Solidigm-branded P41 Plus, covered elsewhere on this site, following Intel's NAND business sale, but the original 660p is still floating around retail and remanufactured markets as a genuinely historic budget NVMe option.
Performance and Speed
1,800 MB/s read within its SLC cache reflects early-generation QLC and PCIe 3.0 limitations, modest even by older Gen 3 standards, and speeds drop further once sustained writes exhaust the drive's dynamic SLC cache on larger transfers.
Historical Significance
This drive normalized QLC NAND in mainstream consumer NVMe SSDs, proving buyers would accept lower endurance and write consistency in exchange for meaningfully lower prices, a trade-off that essentially every current budget QLC drive on this list, including Sabrent's Rocket Q, follows the same playbook Intel established here.
Comparison to Sibling Products
Against its own successor, the Solidigm P41 Plus, covered elsewhere on this site, that drive uses newer QLC NAND and a PCIe 4.0-capable interface for better real-world performance at a similar budget price point, the more sensible buy for anyone shopping new today. Against Sabrent's Rocket Q, also covered on this site, that drive reaches far higher capacities on a similar QLC approach.
Who This SSD Is Actually For
Budget upgraders specifically comparing older-generation QLC drives on clearance or secondhand pricing. This is a legitimate, if dated, way into NVMe storage.
Buyers curious about the drive that established QLC as viable for mainstream consumer NVMe SSDs.
Not for anyone buying new today with other options available. The Solidigm P41 Plus, its direct successor covered elsewhere on this site, outperforms it for similar money.

Expert rating5.8 / 10
A historically important drive that's been cleanly surpassed by its own successor; buy it only at a genuine discount.
Best for
- Budget upgraders specifically comparing older-generation QLC drives on clearance or secondhand pricing.
- Buyers curious about the drive that established QLC as viable for mainstream consumer NVMe SSDs.
- Light-use secondary storage builds where cost matters more than any performance consideration.
Not for
- Not for anyone buying new today with other options available. The Solidigm P41 Plus, its direct successor covered elsewhere on this site, outperforms it for similar money.
- Not for gaming or content creation builds where sustained write consistency matters.
- Not for buyers wanting PCIe 4.0 compatibility; this drive predates that interface generation entirely.
