Recently cable provider decided to bump all from 6Mbps to 10Mbps $55/month. I decided to bump from 10Mbps to 18Mbps for $67/month. Still though not fair since San Diego gets 25Mbps for $57/month. However, still 25Mbps is still behind Japan. In 2006 used fiber there from a neighbor let me share his fiber connection ($60/month he said he paid for fiber) for 2 months and got 100Mbps (12.5MB/s). America is still four or five times slower than Japan and Korea.
7200rpm NAS I can transfer via gigabit 1000Mbps (theoritical 125MB/s) huge files at 21MB/sec. 5900rpm NAS I can copy at 17MB/sec.
Dec 10, 2009 Update it is 21MB/s if I disable journaling just like I had on my other NAS. So essential new harddrives are just as fast.
Now if I was on 10/100 Ethernet max is 12.5MB/s. Not getting 10 times more as harddrives are the bottleneck but twice the speed I believe it’s worth it. Although my hard drive is so busy downloading stuff and unraring it I think I like just unrarring it directly to my NAS which done at 7MB/sec.
I know technically this is approximations but for all intensive purposes the following is correct.
1000KB = 1MB (3.5 inch floppy 1.44MB, CD 700MB, email attachment 10MB limit)
1000MB = 1GB (DVD 4.4GB, DVD-9 dual-layer 8.5GB, 4GB Memory, BluRay disc 25GB)
1000GB = 1TB (1TB, 1.5TB and 2TB hard drives)
CD/DVD/Bluray read/write speeds.
36X CD speed = 5.3MB/s
4X DVD speed = 5.4MB/s
1X BluRay speed = 4.5MB/s
Internet connection speeds
56Kbps = 7KB/s (remember dial up days from 1995, got DSL in 1997)
64Kbps = 8KB/s (ISDN ring a bell anyone, maybe was 128Kbps)
512Kbps = 64KB/s
1024Kbps = 128KB/s
3G (1,000Kbps) = 125KB/s (yea iphone is slow)
1.5Mbps = 192KB/s (some DSL still at this speed and T1s)
6Mbps = 800KB/s (cable and maybe DSL)
10Mbps = 1.3MB/s (cable)
18Mbps = 2.3MB/s (cable)
25Mbps = 3.1MB/s (cable)
50Mbps = 6.3MB/s (still waiting for this in USA)
100Mbps = 12.5MB/s (fiber, 10/100Mbps ethernet)
1000Mbps = 125MB/s (if all switches, routers are gigabit ethernet)
Time to download 10GB bluray.
1.5Mbps = 15 hrs
6Mbps = 3 hrs 45 mins
10Mbps = 2 hrs 30 mins
18Mbps = 1 hr 15 mins
25Mbps = 1 hr
50Mbps = 30 mins
100Mbps = 15mins
Time to copy 10GB bluray to NAS
unrar on the fly 7MB/s = 24 mins
10/100 ethernet 12MB/s = 14 mins
5900rpm 17MB/s = 10 mins
7200rpm 21MB/s = 8 mins
