How large is the cache, which storage technology (SMR or CMR) is used, what kind of filling (air or helium) is used, what is the maximum workload rate per year? what is the maximum internal transfer rate?

The cache is 256 MB. The storage technology is traditional Perpendicular Magnetic Recording (PMR), i.e. CMR. The hard drive is filled with helium (HelioSeal technology). The maximum workload rate is 550 TB per year. The maximum internal transfer rate is up to 255 MB/s. The speed is 7200 rpm. These figures correspond to the specifications for an enterprise hard drive with high reliability and efficiency.
