I'm getting the 'write speed not high enough' message every start up on my system*. If the system is failing a benchmark of 120 KB/sec, how is it that !Speed records IKB and 4KB block write speeds on the SD card in question as 314 and 1067 KB/sec respectively (and larger blocks much faster e.g. 6809 KB/sec for 64KB)? *NS 3.3, RasPi B @ 900MHz, RO 5.21 [RC12, 12-Jan-15]. -- George

Not entirely a waste of time. If during one use of the computer (ie until you next turn it off) you visit multiple pages from any site the cache will still satisfy some of the fetches they require. You could run an Obey file just before you shut down to copy stuff from RAM disk to real disk, and reverse that process soon after booting, though I think if you did you'd need to prune the cache somehow. -- Jeremy C B Nicoll - my opinions are my own.

I'm finding this on my ARMini. Is this common? I get it on my SAM440 very frequently. I'd be very surprised if the write bandwidth was that low as it's a fast SATA drive. Curiously I've never seen the message on my old EEE, which has the slowest SSD write times known to man (it's slower than any HDD I've encountered). I suspect the OS has a lot to do with it, especially when writing lots of small files there's likely to be significant overhead. Chris
