Hi,
I am running out of space on my server at home which is acting as a NAS with a few extras.
I have the following mounts (consolidated for ease );
/: Root area for the OS (Fedora 14) - WD Scorpio black 2.5" 300GB. No space issues.
/home/[USER]: Main users home area - Seagate 1TB 7.2k drive. No space issues and could happily function with 500GB.
/mnt/raid: Storage of all media (Movies/Music/TV/personal data/IT stuff like install files) - 3* WD Black 1TB in Raid 0. Low on space.
/mnt/backup: Archive of all the data on the Raid. 2*WD Green 2TB + 1 WD Green 1.5TB - No space issues.
There is only one user account and I use samba for compatibility with my Win7, Win XP, and WD media players.
I regularly transfer files from the home area to the raid and archive areas and this is slow. The home area also gets a lot of action with reads and writes from other processes running and I believe this may be slowing down the transfers.
I see 5 options;
1. Add 1 or more WD black 1TB drives to the raid.
2. Sell the WD black 1TB drives and replace them with 2TB WD black drives. Possible but a little pricey and would have to wait for the units to be sold before I could buy and rebuild the array.
3. As option 1 + Change the /home/[USER] drive to a WD scorpio 500GB (more than enough space).
4. As option 3 but use a WD RE3/RE4-GP instead of the scorpio black.
5. Same as 4 but sell the WD black 1TB drives and replace with WD RE3/RE4-GP drives as well as the home area.
I can get the RE3s for about the same price as the WD blacks on EBay.
The big question is, are the WD RE3/RE4-GP drives much better than the WD blacks for coping with multiple simultaneous reads and writes ?
I am also concerned that my Raid 0 array is no faster at copying files back and forth than a single WD green 2TB drive (averaging 70-80MB/s on both) and the machines are both on Gb connections with the PC using 2*60GB vertex 2 (raid 0) as source / destination depending on direction of transfer.
Any insight on the usefulness of changing to RE3s or anything else to aid speed-up of transfers would be very welcome. The slow transfers are not a killer but are around half what they should be able to manage and so frustrating.
As I am using in a home environment, I don't need quick recovery hence no raid 5 or 10.
Thanks
