Trouble-shooting and resolving it months down the track was not fun. I think my experience was not typical but if you're going to get one of these drives my recommendation is as soon as you get your hands on it run a few speed tests in the first 24-48 hours to make sure you're getting the performance you paid for. I would still recommend the company (they were definitely concerned with the problem) and the product (I love the R4 and R6 when they are doing what they should be doing). In the end it was definitely nothing to do with my system or the chassis and something to do with the drives or software.but what exactly I won't ever know. In the end they agreed that 300MB/s read or write would be a minimum acceptable speed. At various times I was told things that just didn't seem right to me, like a 100MB/s difference in read and write was acceptable and that 200MB/s read speed was normal for an R4. I paid the retail difference (around $750) and received a refurbished R6.Īll I can say is my R4 was definitely under performing. The last straw was when a attempted fix corrupted my unit and it had to be formatted right in the middle of a job I was working on costing precious time and the promise team still wanted me to "send through a system report when the drive was reinitialised".Īs much as I hate to be one of "those customers" in the end i couldn't take any more delays and uncertainty and insisted on being sent a fresh R6 unit so that even if it was under performing it would at least get me out of the forrest - the read and write speeds are quite a bit faster on the 6 bay units. In the end I had to call the back and forward discussions due to the time and inconvenience it caused me. In the end the entire process - from the first enquiry - took about 3 months. I was sent replacement parts that didn't fix the issue and my computer was accessed remotely for long sessions at a time with no apparent result. The promise support was good - especially when I starting calling instead of using email support but the process of discovering and attempting to solve the issue was excruciating.

In the end I upgraded my unit to an R6 and now my speeds are constantly in the low 500MB/s range - Read and Write - which I am more than happy with. I can absolutely confirm that there was a performance problem with my R4 unit from the start, although I will never know the cause or how it will be fixed. I recommend calling phone support for issues rather than using email support. Never dreamed I'd be so happy to have the problem that started this thread back in my life.

They forced them back to life using remote login. They determined the drives were not dead, just registering dead. UPDATE2: Pegasus phone support was great. Raid 5 provides tolerance for one failed drive but not two. Shut down and removed second drive replacing first. UPDATE: Just removed one drive and booted. The RAID is striped RAID 5 - so I am thinking I could remove drives to see if one of them is causing the bottleneck and if I find one replace it with the new unit. They also sent me a replacement drive unit. You can imagine how this impacts the stop-start nature of video editing. It gets there over about 4 seconds pausing first around 20, then 60, then 90, then 120 and tops out at around 160. What makes this a particular problem is the time it takes to reach 160. Now I absolutely cannot get it to touch 200MB/s and 160MB/s is average.

I thought I was out of the woods!īut then, within a half hour I tested it again. I swapped the drives, fired it up and at first was very happy to see a read speed of 340MB/s. So just shy of December and I have an update.
