Hello Tim,
Here are the ATTO Thunderlink SH3128 features:
12Gb/s SAS/SATA Support
Auto Negotiation between 12Gb/s, 6Gb/s and 3Gb/s SAS/SATA devices
Supports Serial SCSI Protocol (SSP), SATA Tunneling Protocol (STP, SMP, SAT and direct attached SATA protocol
SES and S.M.A.R.T. support
Flash ROM for easy field updates
Wide port end device support
Support for SAS tape devices and transport layer retires (TLR) for error handling
I’ve tried again to write my data to new tape with BRU PE, and it’s wrote less than 2TB.
I’d tested my RAID with Blackmagick speed test, and it show write/read speed about 300 MB/s. I have no more ideas.
