## Description

Pegasus32 R4 US Promise BOX HDD SATA3 5inch*4TB*4 with Thunderbolt3 0 7M cable

Review: Out of the Box RAID Level 5 Photo Storage for Mac. - I purchased this external array to store photos. I was running a 1 TB (RAID1) G-RAID drive until the Mac G-Raid Configurator refused to recognize my G-RAID drive. I decided to try this 12 TB (RAID5) Promise external drive in the 4 bay configuration connected to an iMac Pro running OS X 10.15.2 (Catalina). I am now also using this drive as my Time Machine backup drive. This 4 hard drive array works out of the box as a Level 5 RAID 12 TB logical drive. It has 1 GB of SDRAM. If a single drive in a RAID 5 drive fails you should be able to still read the data from the redundancy on the remaining drives. You can then replace the failed drive. This is important if you are storing your photographs on an external drive, so that you can recover from a single drive failure. Of course, having a RAID5 external drive does NOT protect you from erasing a photo on your external drive or physical damage, such as a fire, to the entire array. You are still going to need to have some type of off site backup of the data stored on this drive. If you are using Lightroom, you may want to tell Lightroom to _backup_ the Catalogue to the same drive as your photos. If you drag your photo folder to this external drive, you can tell Lightroom to find the new location by right clicking in LR on the folder and choosing "Update Folder Location." Thunderbolt 3 cables are quite expensive and this drive ships with a "short" cable. You need to download and install the Mac driver and Promise Utility first onto your Mac. This unit will do a "synchronization" in background looking for bad sectors so do not be surprised by all the drive activity. If you want to purchase a replacement drive, the Promise Utility reports that _my_ unit has 4 Toshiba MD04ACA4 SATA HDDs. Your mileage may vary. This unit is much quieter than my G-RAID despite have two fans, one for the power supply and one for the drive array. I was able to daisy chain this drive to my G-RAID. The drive goes silent when I put my Mac to sleep unlike my G-RAID. Good news is that I eventually was able to reconfigure my G-RAID drive using a Windows 10 computer and the G-RAID Windows Configuration utility. I then reconnected the G-RAID to my Mac and using the Mac Disk Utility I was able to initialized my G-RAID drive.
Review: no coverage for legacy products - Distressed to discover that my pegasus2 8tb raid drive would not be serviced by them. The whole idea was that raid would prevent me from losing my cherished data. What about all the data thats on the drive? so I cant even reformat the drive since the software no longer supports it. No customer appreciation. not inspiring confidence. When you cant respect the effort i put into getting my daymta on your device, I will never buy your product again. That is after having over 8 pegasus raid devices.
