The activity monitor is showing almost 1GB/sec reading and writing and I'm still working away like nothing else is going on. So, I'm copying 300+GB to it from a smaller thunderbolt unit at over 350/MB/sec AND working in a multi-cam timeline ANNNND copying 100+ GB to the internal PCIe drive at about 400/sec and it didn't skip a beat. I've had huge files copying to it while I'm reading from it to work and didn't even notice. This thing does every task as fast as possible. If you're an editor - when you hit play, IT PLAYS. Again it's ANNOYING but I can't in good conscience allow that to degrade the 5-star rating because when you're working away you'll only experience the smooth, fast performance only this drive offers (as of now). With the exception of a minor issue that's more of an annoyance that it 'sleeps' frequently even if the energy saver is set to NOT put the drives to sleep, I've had no issues and the drive performs as advertised.
PROMISE PEGASUS2 R6 REVIEW FREE
The unit is quiet and maintenance free -which could be attributed to my near-religious rebuilding of the directory using Disk Warrior but still. After upgrading to the latest MBP with thunderbolt 2, performance has been as advertised at close to 1GB/sec read/write, even in RAID 5 (losing 1 drive for parity).
PROMISE PEGASUS2 R6 REVIEW UPDATE
I'll update this review after a few months.īought this drive to use with my late 2011 MBP and at first was disappointed at the read write speeds of 500-600 MB/sec. I've rebooted the computer several times since and the drives and the drives are rock solid. The next morning I turned on my computer and the drives worked perfectly. I went to bed that night deeply troubled. I found a test on the internet that hooked up something like 43 thunderbolt devices including a couple of these RAIDS and they all worked perfectly. Promise tech support said it should work perfectly. I tried this a few times and my computer could only partially see the second drive. You cannot have two drives connected to the same computer unless you daisy chain the second one on to the first. The new drives seem vastly better than the old silver ones. Still, for all my bitching, after a lot of comparison shopping, I couldn't find a better product. Can't say it is a recommendation for Hitachi drives. I wonder if the drive failures after only 3 years might have been due to the heat in the enclosure or simply low quality drives. I would have lost all my data, but I had transferred it to one of the new RAIDs. The drive trundled on for a couple of days and didn't seem able to rebuild itself with the new hd. Then I bought a nice Seagate Barracuda drive that matched the specs of the existing drives perfectly. I found the specs of the old hds in the report on the Promise software. The sales guy said just buy any drive that will fit and the RAID would handle it. He referred me to sales saying he didn't know the specs. this didn't make a lot of sense to me as one of the drives failed so quickly. When my old R6 lost a drive after 3 years I called their technical assistance and they didn't know what specs I needed for the drives, but advised me to buy a $220 drive that the unit ships with. You need to be patient with Promise support.
PROMISE PEGASUS2 R6 REVIEW MAC
The RAIDs are so fast, I suspect I can leave the videos on the RAID and get pretty much the same speed as the Mac disk. I put the applications and the video I'm working on on the 1 TB drive. Of course it is way too small to store movies, pictures, documents, etc, so I'm using one of the RAIDS as the main hard drive. They are nearly silent, fast as lightening, and much cooler than the R1 with 6 drives. I bought two of these to go with my late 2013 Mac Pro.
