Specialist storage suppliers may also be prepared to let you return a set of drives if they do not work: talk to them and see if you can agree this.Īssuming that you have chosen the model of drive with which to upgrade your RAID array, there is one final task: try to obtain each drive from a different manufacturing batch. They also discovered a list of drives which had been tested by Promise, and selected one of those.Ĭontacting the vendor’s support service can sometimes be helpful, but they are unlikely to provide any information beyond that of their own compatibility testing. For example, Promise Pegasus R4 drives can safely reach 4 TB, according to Creation Video’s experience. When upgrading an array, check the experience of other users, and compatibility listings available from the vendor. When replacing a failed drive, it is often hard to get an identical model in those circumstances, try to get the closest match in terms of type (HDD/SSD), interface (SATA specification), spin speed, manufacturer, and capacity. There is no point in putting one 2 TB SSD in an array of 1 TB hard disks, and some RAID controllers may not work properly with such a mismatched array. The further that you depart from that, the poorer the array will perform.

Whether software or hardware, RAID systems generally work best and fastest when all the drives in the array are the same model and size. Next, you must decide whether you are replacing one or two failed drives, or intend upgrading the whole array. If you’re using large or fast drives, and are taking the issue seriously, you should opt for SoftRAID note that you will need to use SoftRAID version 5.5.5 or later to run with macOS Sierra, as previous versions are not fully compatible.

Some older hardware RAID controllers can be quite picky as to which drives they will support, or may not support drives larger than a certain size.įor software RAID, most modern units should be fairly agnostic as to what drives you use, as it is the software (AppleRAID or SoftRAID) which does the work. Hardware RAID systems have a hardware controller built into the unit, which you control through a utility in the case of Promise Pegasus models, that is the Promise Utility. The first important question is to determine whether yours is a software or hardware RAID system. In fact many, if not most, external drive arrays can use – and make excellent use of – larger and faster drives than those original specified for them. Browse their user documentation, and most seem very restrictive in terms of the drives which they can support: the Promise Pegasus R4 and R6 models, for instance, specified 1 and 2 TB units. It’s three years since Apple last offered a Mac which could be configured with an internal RAID array, so there are a lot of Macs which now run external RAID systems.
