If users want to do more extensive audio editing, this Android music player provides a companion Equalizer app. While the number of options can be overwhelming at first, it offers users unparalleled control over their audio. It is fair to say that many who work in the IT or tech industry feel that some days can be challenging and stressful. Of course, that does come a bit with the territory. However, there is a difference between having a few stressful days here and there com.A single 2TB Hitachi Deskstar 7K3000 is good for sequential transfer rates of up to ~150MB/s. With six in a RAID-5 configuration, we should be able to easily hit several Gbps in bandwidth to the Pegasus R6. The problem is, there's no single drive source that can come close to delivering that sort of bandwidth.Īpple sent over a 15-inch MacBook Pro with a 256GB Apple SSD. This was the first MacBook Pro I've ever tested with Apple's own SSD, so I was excited to give it a try. The model number implies a Toshiba controller and I'll get to its performance characteristics in a separate article. But as a relatively modern 3Gbps SSD, this drive should be good for roughly 200MB/s. Copying a large video file from the SSD to the Pegasus R6 over Thunderbolt proved this to be true:Īpple's SSD maxed out at 224MB/s to the Thunderbolt array, likely the peak sequential read speed from the SSD itself. That's a peak of nearly 1.8Gbps and we've still got 8.2Gbps left upstream on the PCIe channel. Without a second Thunderbolt source to copy to the array at closer to the interface's max speed, we had to generate data. I ran the test for 5 minutes, the results are below: Promise Pegasus R6 12TB (10TB RAID-5) Performance I turned to Iometer to perform a 2MB sequential access across the first 1TB of the Pegasus R6's RAID-5 array. Without the latest firmware the Pegasus2 will experience random disconnects and failure to reconnect after a reboot.The best performance I saw was 683.9MB/s from our sequential write test, or 5471Mbps. To update with this Pegasus2 firmware (v.64). But a slightly older Pegasus Utility will work. But there is an issue with the latest Pegasus32 Promise Utility and it will not update Pegasus2 firmware.
The Pegasus 2 firmware was updated in 2020, the latest firmware should be used. Note that installing this driver will delete the kernel space driver. Please use the Promise Utility and driver from the Pegasus32, they are backwards compatible with the Pegasus2.
We suggest using the Pegasus user space driver with Ventura or Monterey. As I just responded to a similar issue if you don't mind I will reuse that comment.
