Internal LTO-6 tape drive
The HP EH963A is an internal backup drive that writes to LTO Ultrium 6 cartridges. It provides a native capacity of 2.50 TB and a compressed capacity of 6.25 TB per cartridge. The drive includes a 512 MB buffer to maintain streaming performance. It is designed for organisations that archive large datasets on tape media.
LTO-6 speed ceiling
Native sustained transfer runs at 168.94 MBps and compressed sustained transfer reaches 422.34 MBps. The LTO-6 format caps maximum throughput, so faster host interfaces cannot push data beyond this limit. Data Rate Matching adjusts drive speed to the incoming data stream to reduce stop-and-wait cycles. Buyers who need higher single-drive throughput must move to a newer LTO generation.
AES 256-bit hardware encryption
The drive encrypts data on the tape using AES 256-bit hardware encryption. This feature protects sensitive archives without host-side software overhead. If your compliance rules require a different encryption standard or key-management integration, this drive does not meet that need.

商品問答
Should I plan for the 2.50 TB native capacity or the 6.25 TB compressed capacity?
The drive writes 2.50 TB natively and up to 6.25 TB with 2:1 compression; plan for the native figure unless your data compresses well.
What does the 422.34 MBps compressed transfer rate mean for actual backups?
That is the peak compressed streaming rate; real-world throughput depends on host speed, buffer handling and whether the drive can stream continuously.
What interface standard does the EH963A use and what throughput does it cap at?
The drive supports up to 400 MB/s interface throughput with HP Data Rate Matching to keep the tape streaming at host speed.
