ArGest Backup has no upper data content size limit and can support single stream archives of 8TB or more. Conceptually, because of its 64-bit data handling abilities (even on 32-bit systems), ArGest Backup can process a single backup stream of up to 16 exabytes.
With high-speed tape or disk technologies, ArGest Backup can easily write archives at over 500MB/sec. Of course, that number will be dependent on both the type and size of data being archived and the speed of your source storage devices, but consistent throughput rates of 310MB/Sec when writing to SAS LTO-7/8 tape drives have been witnessed by many customers.

| LTO-9 | SAS, F-C | 40-300MB/sec, 144-1,080GB/Hr | 18TB |
In the table above, the performance range on faster drives depends on your host and filesystem performance. The lower number is average for an older USB-2, SATA-1, or PATA-based system. The higher number maybe even faster than indicated if you have a very high throughput SSD/NVMe or RAID-based filesystem utilizing FC or SAS for the transport layer.
