SSD and HDD

SSD standds for Solid State Devices. HDD stands for Hard Disk Drives.

Operational Temperature

I am quoting from the Seagate Ironwolf manual. 32°F to 149°F (0°C ambient to 65°C drive reported) temperature range with a maximum temperature gradient of 36°F (20°C) per hour. The maximum allowable drive reported temperature is 149°F (65°C).

From this we gather, if your NAS Ironwolf Pro 18TB hard disk is in an airconditioned environment of 24°C (75°F) then you can run continuous reads and writes for for about 2 hours after which you need to stop or pause the reads and writes for about half to one hour to allow for cooling of the internal parts to extend its working life. If your NAS Ironwolf Pro 18TB hard disk is at room temperature which is 35°C (95°F), in Malaysia, then you can run continuous reads and writes for for about 1.5 hours after which you need to stop or pause the reads and writes for about one to two hours to allow for cooling of the internal parts to extend its working life. If you are editing or saving files every so often then don't worry. Make sure there is sufficient airflow to keep them cool.
Some AI programs run your hard disk drives for 24 hours and will lead to failure of the harddisk drives. This is what happened to my Toshiba 16TB drive. It just could not be re-formated and would not work at all.

Advantages and disadvantages of SSD vs HDD

SSD's are electronic non volatile devices which means they will not loose their memory they when powered off. Since they are electronic devices they have no moving parts and silent when comparred to HDDs. This makes them much faster then HDDs too. NVME M.2 SSD's have a Read and Write time of about 3000MB/s where as HDDs have a Read and Write time of 30MB/s to 130MB/s. SATA SSD's, which plug into the HDD connectors, have a read and write speed of about 500MB/s. This means that your C:\ or boot drives are SSDs. SSD sizes range from 120GB to 2TB of memory where as HDD sizes vary from 500GB to 20TB. 1TB is about 1000GB. SSDs normaly have a life expectancy of 5 to 10 years where else HDD's have a life expentency of about 5 years. This makes HDDs good for saving large amounts of data for a years.

One can clone HDD to SSD but you would need specialist software which one can download from the internet. For example you can clone HDD to SSD using macrium reflect. SSD 1TB & 2TB price malaysia is shown below. HDD Malaysian prices are shown below
