Údržba
Solid State Drives generally require less maintenance than traditional hard drives. However, to ensure optimal performance and longevity:
- Aktualizace firmwaru: Periodically check the Lexar official website for any available firmware updates for your NM790 SSD. Firmware updates can improve performance, stability, and compatibility.
- Příkaz TRIM: Ensure your operating system has TRIM enabled. TRIM helps the SSD manage its data more efficiently, preventing performance degradation over time. Most modern operating systems enable TRIM by default for SSDs.
- Vyhněte se plné kapacitě: I když SSD disky fungují dobře i při téměř plném zaplnění, ponechání volného místa (např. 10–15 %) může pomoci udržet optimální výkon a prodloužit životnost disku.
Odstraňování problémů
If you encounter issues with your Lexar NM790 SSD, consider the following common troubleshooting steps:
- SSD nezjištěno:
- Ověřte, zda je SSD disk správně usazen ve slotu M.2.
- Check your system's BIOS/UEFI settings to ensure the M.2 slot is enabled and configured correctly (e.g., NVMe mode).
- Ujistěte se, že máte aktuální ovladače základní desky.
- For PS5, ensure the SSD is fully inserted and the cover is properly secured.
- Pomalý výkon:
- Confirm your system supports PCIe Gen4. If connected to a Gen3 slot, performance will be limited to Gen3 speeds.
- Check if TRIM is enabled (as mentioned in Maintenance section).
- Ujistěte se, že ovladače vašeho systému (čipová sada, NVMe) jsou aktuální.
- Monitor SSD temperature. Excessive heat can cause thermal throttling, reducing performance.
- Poškození/chyby dat:
- Spusťte utilitu pro kontrolu disku (např. chkdsk on Windows).
- Ensure proper shutdown procedures are followed to prevent data loss.
- Consider updating SSD firmware.
