Promise Technology R4 Overview

The Promise Technology 8TB Pegasus2 R4 is a Thunderbolt 2 RAID storage array designed for simultaneous streaming, editing, and backup of high-resolution videos and large multimedia files. This storage array's Thunderbolt 2 interface offers high-speed connectivity. The Pegasus2 R4 stores up to 8TB of data spread across four 2TB 7200 rpm SATA drives.

RAID levels 0, 1, 5, 6, and 10 are also supported; each level offers configuration options for capacity, data protection, redundancy, and speed.

The Pegasus2 R4 storage array has dual Thunderbolt 2 ports, one port for direct system attachment and another port for daisy-chaining up to 6 Thunderbolt 2 devices. This storage is formatted in the HFS+ file system for Mac and is compatible with Time Machine in OS X, which automatically backs up your entire Mac system.

Thunderbolt 2

The Pegasus2's Thunderbolt 2 interface is sufficient for handling and accelerating 3D or 4K (UHD) workflows. Thunderbolt 2 uses the same cable as the previous generation but has double the available bandwidth for a maximum throughput of 20Gb/s.

4K Workflows

The bandwidth of Thunderbolt 2 and the Pegasus2 is designed to give professionals the ability to edit and view live 4K streams while backing up the same file to a single or daisy-chained Pegasus2 storage array system.

question

OK. I'm new to this Raid array thing. This one here says it has 4-2TB Hard Drives. If your saving stuff like photos in Lightroom and your digital music does it fill up One HD then start storing data on the next HD then when that fills up go on to the next HD & so on, or does it store the same data on the 4 different HD's? For making multiple safe copies.
Asked by: Lou
Raid exists to guard again disk failure. there are many levels of raid. Raid 1 mirrors data across two disks. One disk fails, the other has your data. Or Raid 0 can be used to speed up getting big files into RAM by striping, i.e., splitting one copy of data across two disks so read speed is essentially twice normal. Of course if a disk dies in Raid 0 you lose half your data. Speed is big if you have video or giant giant image files. Raid 10 does both mirroring and striping which takes 4 disks. Its both fast and safe but costly. I have two of these units and I use Raid 10. Fast and Safe.

question

My wife and I work from our home studio and both run macs. Can we connect both machines to this unit at the same time?
Asked by: Anonymous
Unfortunately, you can't. The Raid drive utilizes Thunderbolt to connect to a single computer. It is not a Networkable drive. I suggest looking for a NAS drive, if that is what you need. I have loved my 8TB Pegasus and HIGHLY recommend it if you need a fast, Raid system for editing audio, video, or Photoshopping.

question

What is the power (Watts or Amps) of the unit?
Asked by: Dennis S.
The only spec I see says 78 Watts max load. However, Apple gives this same specification for both the R4 and the R6 so I expect that that is the maximum draw for the same power supply being used in both models. That implies that the R4 will have a lower maximum draw.

question

Will it be possible to change drives to 3 or 4 TB drives later on, or are we committed to 2 TB SATA drives with this unit?
Asked by: Serge
Yes, per the specifications at promise dot com (products > thunderbolt > pegasus2 > resources > pegasus2 product manual > page 3)The Pegasus2 is shipped with 3.5 inch SATA Hard Disk Drives (HDD) installed in the drive carriers and placed in the drive bays.Users can replace the drives with any of the supported drive types. For many RAID configurations, it is best to install drives that are identical in type and storage capacity.The following storage disk types are supported on the Pegasus2: 2.5-inch and 3.5-inch SATA hard disk drives 2.5-inch SSD 2.5-inch and 3.5-inch Hybrid HDDIt's a great high-speed array!
