Quick verdict

Choose the Intel 660p if your computer supports M.2 2280 NVMe and you need 1TB for games, applications or general storage. Choose the Kingston Q500 if you need a 2.5-inch SATA drive for an older PC or laptop and place more weight on the supplied reliability and support scores. Avoid using the Intel as a frequent, sustained heavy-write drive if that is your primary workload.

Detailed comparison

Performance

The Intel 660p has the stronger peak performance profile on paper, with PCIe NVMe 3.0 x4 connectivity and rated sequential read and write speeds up to 1800MB/s. The Kingston Q500 is limited by its SATA interface and lists a 500MB/s read speed, although this remains a meaningful improvement over a mechanical hard disk for daily use. The supplied performance score favours Kingston, reflecting its strong everyday results, but Intel is the better fit for workloads that benefit from higher sequential transfer rates. For sustained heavy writes, Intel reviews caution that performance can fall sharply once its SLC cache is full.

Speed

The Intel's listed speed ceiling is much higher: up to 1800MB/s sequential reads and writes versus Kingston's listed 500MB/s read speed. Reviews show that the Intel can be quick for normal-sized transfers and read-focused tasks, but its QLC cache behaviour can reduce speed during large or frequent writes. Kingston cannot match NVMe throughput, yet its supplied speed score is higher and review feedback consistently describes it as fast for ordinary laptop and PC upgrades.

Reliability

Kingston has the clearer advantage in the supplied reliability data, scoring 88 compared with 69 for Intel. Q500 reviews consistently describe stable, problem-free use for routine upgrades. Intel reviews are often positive, but also raise concerns around QLC write endurance, cache-related slowdowns and occasional heat; the aggregated overview notes mixed reliability reports. For a light SATA upgrade where consistency is the priority, the evidence favours Kingston.

Intel 660p Series 1TB NVMe SSD

Pros

  • 1TB capacity provides substantially more room for games, applications, media and general files.
  • PCIe NVMe 3.0 x4 interface with rated sequential reads and writes up to 1800MB/s.
  • M.2 2280 format avoids the need for a 2.5-inch drive bay and SATA data cable.
  • Strong value score and review feedback for game libraries and read-focused storage.
  • High customer rating from 2,737 reviews, with frequent praise for straightforward installation.
  • Compatible with PCs, laptops, and systems that accept M.2 2280 PCIe drives.

Cons

  • QLC NAND is less suited to frequent, sustained heavy-write workloads than more endurance-focused SSD designs.
  • Write performance can drop substantially after the SLC cache is exhausted during very large or repeated transfers.
  • Some reviews report heat, while others report cool operation under a heatsink.
  • Reliability feedback is mixed, and the reliability and durability scores trail the Kingston drive.
  • Requires an M.2 2280 PCIe/NVMe-compatible slot; it is not a direct replacement for a 2.5-inch SATA drive.
  • Reviews suggest simultaneous read and write activity can be less smooth in demanding scenarios.
Intel 660p Series 1TB NVMe SSD

Kingston Q500 240GB SATA SSD

Pros

  • TLC-based SATA SSD with strong reliability and durability scores.
  • 2.5-inch SATA format is a practical upgrade path for many older laptops and desktops.
  • Rated read speed of 500MB/s is a major improvement over a mechanical hard drive for everyday use.
  • High customer satisfaction score, supported by 9,746 reviews and repeated reports of stable operation.
  • Strong compatibility score for PC and laptop upgrades, with listed support for SATA 3.0Gb/s and 6.0Gb/s.
  • Shock-resistant design and light 41g weight.

Cons

  • 240GB capacity is restrictive for large game libraries, extensive media collections, or sizeable project files.
  • SATA connectivity and a 500MB/s rated read speed are far below the Intel drive's rated NVMe throughput.
  • Feature score is lower because this is a basic internal SATA SSD rather than an NVMe model.
  • Review feedback notes that DRAM-less behaviour can make large small-file copies slower.
  • It needs a 2.5-inch bay or suitable mounting position plus SATA data and power connections for internal use.
  • It is not the appropriate choice for a system that only accepts M.2 NVMe storage.

Final verdict

The Kingston Q500 240GB is the better overall option in the supplied scoring, thanks to its lead in overall assessment, reliability, durability, compatibility, customer satisfaction and warranty support. It is the safer recommendation for a straightforward 2.5-inch SATA upgrade where 240GB is sufficient and stable everyday performance is the goal.

However, the Intel 660p 1TB is the more useful drive for many compatible NVMe buyers. It offers four times the capacity and much higher listed sequential speeds, making it better suited to game libraries, larger application collections and general file storage. Its compromise is QLC behaviour: review evidence indicates that sustained large writes can slow once the cache is exhausted, and long-term feedback is less uniform. Select by interface first, then capacity and workload, rather than treating these two SSDs as identical alternatives.

Frequently asked questions

<p>Which is better overall, the Intel 660p 1TB or Kingston Q500 240GB?</p>

The supplied overall score favours the Kingston Q500, largely because it scores better for reliability, compatibility, customer satisfaction and warranty support. However, the Intel 660p is the more capable choice for a compatible NVMe system needing 1TB capacity and higher rated sequential speeds. The better purchase therefore depends strongly on interface support and storage needs.

<p>Is the Intel 660p faster than the Kingston Q500?</p>

On their listed sequential specifications, yes. The Intel 660p uses PCIe NVMe 3.0 x4 and is rated up to 1800MB/s for sequential reads and writes, while the Kingston Q500 is a SATA SSD with a listed 500MB/s read speed. The Intel can slow substantially on very large sustained writes after its cache is filled.

<p>Which SSD offers more storage capacity?</p>

The Intel 660p offers 1TB, compared with 240GB for the Kingston Q500. That makes the Intel more practical for larger game libraries, media collections and general file storage. The Kingston's capacity can suit an operating system, core applications and light everyday storage, but buyers should confirm that 240GB is enough before choosing it.

<p>Which SSD is better for upgrading an older laptop?</p>

The Kingston Q500 is usually the more direct fit when an older laptop has a 2.5-inch SATA bay, because it uses the standard 2.5-inch SATA format. The Intel 660p only fits systems with an M.2 2280 PCIe/NVMe slot. Check the laptop manual for its physical slot type and supported interface before buying either drive.

<p>Is the Intel 660p suitable for gaming?</p>

Yes, provided the system has a compatible M.2 NVMe slot. Reviews frequently identify game storage as a suitable use case, and the 1TB capacity is much more accommodating than 240GB. Its QLC design is less ideal for repeated very large writes, but game libraries are generally a more read-focused workload according to the supplied review feedback.

<p>Which drive is more reliable according to the provided data?</p>

The Kingston Q500 has the higher supplied reliability score, and its reviews repeatedly describe stable, trouble-free everyday operation. The Intel 660p has mixed long-term reliability feedback, with its score interpretation identifying QLC endurance and reports of possible heat as limitations. This does not mean every Intel drive will fail, but Kingston has the stronger evidence in this comparison.

<p>Which SSD is easier to install?</p>

Both are internal drives with strong setup scores. The Intel is simple where an accessible M.2 2280 NVMe slot is available: it mounts with a small retaining screw and then needs to be initialized or formatted. The Kingston is straightforward in a compatible 2.5-inch SATA system, but requires appropriate SATA power and data connections.

<p>Does the Kingston Q500 have better endurance than the Intel 660p?</p>

The provided data points toward Kingston for durability and reliability, and the Q500 is specified with TLC while the Intel uses QLC. Intel review feedback specifically warns that the 660p is less appropriate for heavy, frequent writes and has lower endurance considerations. Exact endurance results vary by workload, so neither drive should be selected without considering intended write volume.
