As I mentioned in the previous post, the options boiled down to tape or an external hard drive. I chose to use an external hard drive. So far, that option is working okay if I ignore the fourteen to fifteen-hour-long initial syncs of the drives.
At a sustained write speed of one hundred and fifty-two megabytes per second, the entire NAS pool takes nearly fourteen hours to sink initially. I doubt I can get sustained write speeds much higher without spending several thousand dollars. I am not even sure if they make seven Tebibyte SSDs.
A Tebibyte is the base two version of a Terabyte. Excluding storage device sizes Tebibytes and Terabytes are identical. However, the difference is why a formatted storage device is always smaller than its listed capacity. The formated capacity is given in Tebibytes, but the listed capacity is in Terabytes.
That one hundred and fifty-two megabytes per second write speed translates to a wire speed of 1.275 Gigabits per second on the USB 3 bus, which is pretty reasonable for a mechanical hard drive using the full performance options available on USB 3.
