Группа выше: Износ, надёжность и продление жизни SSD
Смысл: The main idea is that SSDs experience inevitable physical degradation due to electron leakage in NAND memory, making them unreliable for long-term offline storage compared to HDDs.
Unlike HDDs, SSDs lose data over time due to the physical leakage of electrical charges from their memory cells, especially when left without power.
Смысл: The main idea is that SSDs are unsuitable for long-term 'cold' storage because they rely on unstable electrical charges that leak over time due to quantum tunneling and physical wear, a process accelerated by heat and high-density cell architectures (like QLC).
SSDs store data as electrons in tiny traps; over time, these electrons leak out, causing data corruption. This happens faster on cheaper, high-capacity drives (QLC) and in hot environments. Don't use SSDs for long-term archival storage without powering them on periodically.
Смысл: The main idea is that while high-density SSDs (QLC) offer more storage for less money, they suffer from significantly lower endurance and unstable write performance compared to TLC and enterprise-grade drives, especially under sustained heavy workloads.
While QLC SSDs are affordable high-capacity alternatives to HDDs, they exhibit drastic performance drops under sustained loads compared to the more stable and durable TLC and enterprise SSDs.
Смысл: The main idea is that QLC SSDs offer a cost-effective way to increase storage capacity for average users, but they are technically inferior to TLC/MLC in terms of speed and lifespan, making them suitable only for low-intensity workloads.
QLC SSDs provide high capacity and low cost for basic home use but lack the speed and durability required for professional or high-performance computing.
