Getting Some New Hard Drives

Finally, getting NAS drives for my file server.

NASDrives

 

I have previously used desktop hard drives but these drives pcitured above are specifically meant for NAS.  It has TLER (Time Limited Error Recovery) and higher MTBF (Mean Time Before Failure).

I looked up NAS devices and saw that a lot of the higher end ones had about 100 MB/s Read/Write performance on RAID 10 drives.

So I was curious what my system had which is a Whitebox Linux with RAID10.

I found this tool

And I tried it out, I was pretty floored

It was some crappy performance with 34 MB/s Write and 60MB/s Read

I changed the config from

socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

to

socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536

And it was much better

Not sure how accurate those numbers are but I feel better.

My new drives are slower though, but the slow speeds reduce vibration, the old drives are 750GB 7200RPM drives, the new ones are 1TB 5400RPM drives.

So hope it can keep up the 100MB/s performance.

Was a long day, had a LOT to do, was hoping to work out, but only can find time to do some pushups and situps.
