Having a debate with a vendor who wishes to provide a production server equiped only with a single Intel 320 80GB SSD. Not going to get into details but it is a very proprietary purpose built box - we don't have a choice. Nightly full images to another drive will occur although this means 3-4hrs (including support getting onsite) to recover from a failure. Writes are expected to be around 15GB/day and the drive will likely never near filling. Vendor claims that the chances of failure of this single SSD are less than that of 2 X Raid 1 HDD. Personally I doubt there are any numbers to prove this. The other suggestion is that SSD in RAID have a higher likelyhood of failing at the same or near same time. This I can believe and is why if I was doing the setup with RAID 1 I would purposely hammer one drive with writes before installing or use a preworn drive.
For now We agreed to at least monitor wear and perhaps change the drive every 2 years even if within normal parameters.
Any feedback appretiated. Bottom line is as far as I am concerned nobody is putting out servers with single SSD drives and I want to know is if my concern is valid/warranted or not?
Thanks!
