After we installed two SSD discs in a MacBook Pro we had thought of putting them in RAID. Even though we gave up (we will explain why later),Barefeats tested a RAID of Intel X25-M disks.
The results are as you would expect with data flows for reading exceeding the 500 MB/s matching what we obtained with a Mac Pro also equipped with a RAID of two SSD. On the other hand, they did not test battery life of the machine with such a RAID, and this is where the problem is. We have tried to estimate the battery life of the portable by requesting the two discs at the same time. The result does not surprise us. It dropped significantly, the two SSD consuming much more than a traditional hard drive, which is not the case when one of the disks contains the system and the other the data. One finds oneself once more with the usual trade off with portables, power and speed against battery life,even though a SSD RAID bring
