发帖数: 757 | 1 DSM4.1, between PC (old i3) and N54L, there are two gigabit switches in
between. PC source disk is Windows 7 soft Raid 1.
All the diskes used （PC & N54L） are old SATA ones, not II or III. I think
all are 1.5G.
共装了五块硬盘, 单个大文件读写（5G file):
1&2: Raid 1, 640G, 98G space left.
Write 58M/s
Read 60M/s
3: 1.5T, 230G space left.
Write 60M/s
Read Started from 70M, slowly slowed to 42M when finished.
4: 250G(stock), 210G space left.
Write 64M/s
Read Started from 90M, slowed down to 60M slowly, then 60M.
5: 1T, 50G space left.
Write 45M/s this one is strange, speed start from 10M, slowly pick up until
around 45M.
Read 52M/s
Any method to improve the speed？ I think someone said he got 100M read. | a***e

WNDR3700 should handle gigabit no problem.
GFS啊，3700可不便宜，当switch用
话说你没刷什么东西吧
