Intel lists the bulk price as $9.95 on their ARK site and the TDP is 2.8W. four channels) and it connects to the RAID controller through a PCIe 2.0 x4 interface. The Thunderbolt controller is Intel's DSL5520 with two Thunderbolt 2 ports (i.e. Like many Thunderbolt devices, the M4 has two Thunderbolt 2 ports for daisy-chaining. A quick look at PMC's RAID controller lineup suggests that the silicon is the PM8011 SRC 8ењ†G, which is an 8-port SATA/SAS 6Gbps controller with a PCIe 2.0 x8 interface. The RAID controller is covered by the heat sink, so I do not have a photo of it, but I was told that the silicon itself is from PMC with custom Promise firmware. There are a few screws that need to be removed until the top comes off and you end up having access to the PCB along with the rest of the components (PSU, fan, etc.).

Officially Promise only guarantees compatibility with the Toshiba drive, although the user manual suggests that the drive does not have to be the same make and model. The drives are attached to the bays by four standard hard drive screws, so any 2.5' drive will work. In the end, 4TB is not that much if you deal with 4K video.ДЇortunately Promise has made hard drive swaps convenient as pressing the button on the bay will free the lever, which you simply pull to get the drive out. Promise told us that they are not offering 4x1.5TB or 4x2TB configurations due to price sensitivity as $999 is quite expensive to begin with, although I am not sure if I agree because I could see video professionals paying more for increased capacity. two-platter drives, so we are not dealing with super high density here. Our review unit shipped with four 1TB 5,400rpm Toshiba hard drives.

While there are arguably cheaper and larger external 3.5' hard drives around, the M4 provides redundancy via RAID 5, 6 and 10, which is more or less a must for professional video editing because data loss could end up being very expensive. Promise markets the M4 as a solution that offers portability for over an hour of uncompressed 4K footage.

The M4 is available for $999 in the Apple Online Store and the target market for the M4 and the whole Pegasus2 family is video professionals.

Sadly Thunderbolt 2's ten watts of power is not capable of powering the M4, so it is not a fully portable solution like regular external hard drives are. To fix this, Promise is offering a 4-bay 2.5' RAID solution called the M4.ДЄside from capacity, the M4 offers everything that the R4 does as you get hardware RAID 5 and two Thunderbolt 2 ports for daisy-chaining.В The weight comes in at almost one third of the R4's weight and the dimensions are considerably smaller too, which makes the M4 a lot more portable than the rest of the Pegasus2 lineup. The downside, however, is that 3.5' drives are physically larger and heavier, which makes a multi-bay enclosure rather difficult to move around on a regular basis.

Typically multi-bay external storage devices tend to utilize 3.5' drives due to the lower cost and higher capacities.
