SSD Recommendations Based on Flash Memory Type
Choosing a high-quality SSD is essential to ensure optimal data retention. Here are some SSD recommendations based on flash memory type:
- SLC (Single-Level Cell):
- Samsung 983 DCT: This SSD is known for its reliability and high performance, ideal for business and industrial applications.
- Intel Optane SSD 900P: Provides exceptional performance and durability, perfect for professional users who need high speed and longevity.
- MLC (Multi-Level Cell):
- Samsung 860 Pro: Known for its high speed and durability, this SSD is a great choice for users who need optimal performance and good data retention.
- Crucial MX500: Offers a balance between performance and cost, with good durability for everyday use.
- TLC (Triple-Level Cell):
- Samsung 970 EVO Plus: Provides excellent read/write speeds and decent durability, perfect for users looking for high performance at a reasonable price.
- Western Digital WD Blue 3D NAND: This SSD offers a large capacity with good performance, ideal for everyday data storage.
- QLC (Quad-Level Cell):
- Samsung 860 QVO: This SSD offers a large capacity at an affordable price, suitable for data storage that does not require high performance.
- Intel 660p: Offers a good balance between large capacity and decent performance, at a competitive price.
Analysis
Based on information from Quora and PCWorld, the claim that SSDs can retain data for up to 50 years without power tends to be exaggerated. Factors such as the type of flash memory, storage environment, temperature, and frequency of use greatly affect the SSD’s ability to retain data.
| Factor | Influence on Data Retention |
| Types of Flash Memory | SLC/MLC is better than TLC/QLC in terms of data retention |
| Temperature and Humidity | High temperatures accelerate data degradation |
| Endurance and Write Cycles | Frequently used SSDs have worse data retention |
| Long-Term Storage | For the long term, SSDs should be stored in ideal environmental conditions |
Conclusion
Based on various research and user experience, Solid State Drives (SSDs), despite their high speed and performance, are not ideal for long-term data storage without a power supply. Data on SSDs can degrade over time, especially if stored in sub-ideal temperature conditions.
Understanding the type of flash memory used in SSDs is essential to know the data retention capabilities and memory cell lifespan. SLC (Single-Level Cell) offers the best data retention, while QLC (Quad-Level Cell) has the worst data retention. In addition, storage conditions such as temperature and humidity also greatly affect the lifespan of the data on the SSD.
