Raw measurements

The following three commands were run under Linux over a SATA-I interface, giving the results shown.

# hdparm -Tt /dev/sdb
/dev/sdb:
 Timing cached reads:   2256 MB in  2.00 seconds = 1127.62 MB/sec
 Timing buffered disk reads:  178 MB in  3.01 seconds =  59.04 MB/sec
# dd if=/dev/sdb of=/dev/null bs=4096 count=4096
4096+0 records in
4096+0 records out
16777216 bytes (17 MB) copied, 0.242752 seconds, 69.1 MB/s
# dd if=/dev/zero of=/dev/sdb bs=4096 count=4096
4096+0 records in
4096+0 records out
16777216 bytes (17 MB) copied, 0.262695 seconds, 63.9 MB/s

Technology in brief

A cluster communication interconnect which can be utilised without special drivers by any platform which supports Serial ATA connectivity regardless of architecture and operating system.

The unique approach also offers “centralised distributed” storage, allowing a physically remote disc to be accessed as a local disc — reduces heat, noise, and vibration, improves cooling, and removes points of failure within cluster nodes.
