Speed / Size Questions

[SilverJS]

Guys,

Just getting started with FreeNAS, have a couple of questions :

1. I originally used 8.0 RELEASE, and created a RAIDZ2 pool using my 6 3TB hard drives. I can't remember that clearly, but I am pretty sure I saw something like 11.7 TB available, which made sense to me. Then, I tried re-creating the pool using 8.0.1, and can only get 10.7 TB now (I think it says TiB?). I have tried re-creating the pool with 8.0, but my drives aren't even visible in the GUI pool creation window if using 8.0! All is well with 8.0.1, but again, at what is seemingly a reduced capacity...?

2. I think my network might be quite slow (we have one of those Telus all-in-one modems/routers), but I tried writing a file to my newly-formed pool, and was getting 12 Mb/sec writes, and about the same on reads. This, to me, seems quite slow...? I'm not after performance, mind you, but after seeing guys report anywhere from 80 to 500 Mb/secs....

Thanks!

your router prolly only has 100mbit ports, thats a technical 12.5mb/s. Investing in a gigabit switch to hang behind it would benefit greatly if thats the case.

1000 bits to a kilo bit or 1024 bits to a kilo bit, that's the question we get dicked around with by the drive manufacturers.

their 3 TB is 3,000,000,000,000 bytes

3,000,000,000,000 bytes / 1024 = 2929687500 KB
2929687500 KB / 1024 = 2861023 MB
2861023 MB / 1024 = 2793 GB
2793 GB / 1024 = 2.72 TB.

4 drives * 2.72 TB = 10.91 TB. you misread it the first time, it said 10 point something, not 11.

(Making the assumption you mean B for Byte and not b for bit)

12 MB/s is about 100 mb/s, which would conform to a 100/mb switch. check to see if it's 100/mb or gigabit. you should upgrade to gigabit if you have the money. you can be a simple as buying a 4-8 port gigabit switch, and move all your devices to it, then connect the switch to your existing router.

the 500 MB/s you are misinterpreting, those are speeds local to the FreeNAS box, not over the network.

OK, so this all makes sense then. However, the router we have is a combined router and modem - I guess, in this case, a gigabit switch would not really help, since I can't change the router part individually...?

You can connect your PC and your NAS to a Gbit/s switch then they will communicate with 1Gbit/s and connect one port from this switch to your router so only the internet is limited to 100Mbit/s (it´s probably slower)

Went out today and bought a gigabit switch, worked perfect. =) Transfers now start at about 80 mb/sec, slowing down to 65-70 steady state.

Thanks for the tip! =)

glad it's working faster, still hoping you meant MB and not mb, big difference in speed.
