Using one of our main applications at work as the test case to justify a move to SSDs, times for running the unit tests (times averaged over 5 runs of each) were: (mins:seconds) 1x magnetic drive with everything on one drive: 3:42 1x SSD with everything on one drive: 0:54 1x magnetic drive (OS), 1x SSD (documents/project files/etc): 0:52 1x magnetic drive (OS), 1x SSD (documents/project files/etc) with temp folders, paging file etc on SSD: 0:44 2x SSD (one for OS, one for documents/project files/etc): 0:33 2x SSD (RAID 0) with everything on one drive: 0:31 RAID 0 has its place when disk access is a major bottleneck (eg video production, music studio workstations, high volume database server etc) but for a software development it's pretty wasteful when you get near-enough indistinguishable performance by having the two drives running separately, plus double the storage space and only risking half as much data if one of them fails. PS: those numbers are from last-gen SSDs (read/write around 250/200Mbps) so I would expect the performance of a single current-gen SSD (around 500/400) to be even closer to the two drive configurations making a RAID 0 setup even harder to justify.

I think SSDs have eliminated the need for RAID0 on most single user machines.

I have a raid card with 4 drives and deciding on whether to use 2 drives in RAID 0 and 2 drives in Raid 1 -- regards, Preet, Overlooking the Ocean, Auckland Click here <https://www.mailcontrol.com/sr/MZbqvYs5QwJvpeaetUwhCQ==> to report this email as spam.
