flitschbirne Posted October 25, 2013 Share #1 Posted October 25, 2013 (edited) Hi everyone. I have XPEnology (DS3612xs_4.2-3211) installed on a HP Microserver N54L. The DMS is installed on a internal 250GB SATA harddrive. Furthermore I have two 2TB WD Red harddrives installed and under DSM I configured them as RAID1. When I copy data on the RAID1 I get a data throughput of 55 MB/s, but I have a gigabit network at home. I red that people have up to 110MB/s. Is there anything I can improve to get more data throughput? Gruß! Edited October 28, 2013 by Guest Link to comment Share on other sites More sharing options...
MarsManden Posted October 25, 2013 Share #2 Posted October 25, 2013 Hi Did you choose to check the disks for errors when creating the RAID as recommended? Has it finished checking the disks? Checking the disks may take 5-6 hours for 2TB disks. I'm able to reach 100MB/s just using the 250GB disk, that came with the server. Have you tried making a volume without RAID on the 250GB disk?

Dadudeondacouch Posted October 26, 2013 Share #3 Posted October 26, 2013 I did have 2 3tb red nas drives in raid1 on my n54l and I was getting 100mb+ everything is new I have change my setup now though. I use the bays custom bios and trantor's x64 3211 build. Link to comment Share on other sites More sharing options...
shteve Posted October 26, 2013 Share #4 Posted October 26, 2013 How are you copying data to it? If copying from one area of the microserver to another via a PC, you'll see about 50MB/sec. If not, check your network card settings - you might be running half duplex (shouldn't half your throughput, but will have an impact). Link to comment Share on other sites More sharing options...

Yes I checked the disks for errors. I let it run all night, it was finished in the morning. I never tried to copy something on the 250GB because I don't need it. All the data I need is stored on the RAID1 with the two 2TB WD Red drives... How are you copying data to it? If copying from one area of the microserver to another via a PC, you'll see about 50MB/sec. If not, check your network card settings - you might be running half duplex (shouldn't half your throughput, but will have an impact). From two different Windows 7 PCs over a samba share. The network is fine, I checked everything. All Nics automatically choose Gigabit connection, Cat6 cabels and a good gigabit switch from HP...

shteve Posted October 28, 2013 Share #6 Posted October 28, 2013 I suppose it's possible for the RAID1 itself to be having that kind of impact, after all it is writing the same data twice. What are your read speeds copying from the microserver to your win7 PCs? Link to comment Share on other sites More sharing options...
fonix232 Posted October 28, 2013 Share #7 Posted October 28, 2013 RAID1 will have the speed around 50-60MBps. I myself use my hard drives in a Synology Hybrid RAID, and I can get speeds up to 80-90MBps on wireless. Wired can go up to 120-130MBps momentarily, then stabilizes around 110-120.

flitschbirne Posted October 28, 2013 Author Share #8 Posted October 28, 2013 In the future I wanted to buy a third harddrive and go from RAID1 to RAID5. Can I expect a performance increase with a RAID5? I mean it has to write the same amount of data as in a RAID1 plus parity stuff... Link to comment Share on other sites More sharing options...

Have you tried making a volume without RAID on the 250GB disk? Just copied some HD videos on the 250GB disk where DSM is installed (configured as Synology hybrid raid - SHR). Also 50-55MB/s...

MarsManden Posted October 28, 2013 Share #10 Posted October 28, 2013 From where do you copy the files? Are you sure that it isn't your source, that isn't able to deliver more than 55MB/s? If my harddisk on my source computer is fragmented, I also see low transfer speeds. How are the led-light for the harddisk on the N54L behaving when copying files to it? Is it constant on? If not, then the harddisk in the N54L isn't the bottleneck. Link to comment Share on other sites More sharing options...

If not, then the harddisk in the N54L isn't the bottleneck. Oh man you are right. I copied the data from an older 500GB SATA harddrive in my gaming pc to the raid1. Now I tried copying something from my SSD harddrive and there you go. 110MB/s!!! I wouldn't have thought that this 500GB harddrive does not deliver the speed...
