  1. http://www.anandtech.com/storage/showdoc.aspx?i=3531&p=13 New vs Used SSD Performance We begin our look at how the overhead of managing pages impacts SSD performance with iometer. The table below shows iometer random write performance; there are two rows for each drive, one for “new” performance after a secure erase and one for “used” performance after the drive has been well used. 4KB Random Write Speed New "Used" Intel X25-E 31.7 MB/s Intel X25-M 39.3 MB/s 23.1 MB/s JMicron JMF602B MLC 0.02 MB/s 0.02 MB/s JMicron JMF602Bx2 MLC 0.03 MB/s 0.03 MB/s OCZ Summit 12.8 MB/s 0.77 MB/s OCZ Vertex 8.2 MB/s 2.41 MB/s Samsung SLC 2.61 MB/s 0.53 MB/s Seagate Momentus 5400.6 0.81 MB/s - Western Digital Caviar SE16 1.26 MB/s - Western Digital VelociRaptor 1.63 MB/s - Now keep in mind, Unraid's purpose is not random reads and writes, but more sequential. So let's loko at the average write speeds: According to Tom's Hardware Guide: http://www.tomshardware.co.uk/charts/2009-flash-ssd-charts/Average-WriteTransfer-Performance,718.html These values can be double with short stroking drives: INTEL X25-M is limited to 75 MB/s write throughput Intel X25-E 155 MB/s AVG but needs a sas controller I believe. ACARD is reasonable price for video editing! ACARD ANS-9010 150MB/s write (245$ plus ddr2 cheap ram 40$ for 4GB and up) Problem is sata2 can only go so fast! 510MB/s in raid0. But limited to 64 GB of space. http://benchmarkreviews.com/index.php?option=com_content&task=view&id=308&Itemid=60&limit=1&limitstart=11 Very cool price for 1TB of insane speed on the PCIe slot! OCZ 1to4TB SSD PCIE card 400-500MB/s Write sustained speeds. 1500$ to 2000$ http://www.engadget.com/2009/03/05/oczs-z-drive-puts-1tb-of-blazing-ssd-capacity-in-your-pcie-slot/ Fusion Iodrive 1,400MB/sec http://www.engadget.com/2009/03/11/fusion-io-breaks-out-roomy-nimble-iodrive-duo-ssds/ Note that the “used” performance should be the slowest you’ll ever see the drive get. In theory, all of the pages are filled with some sort of data at this point. All of the drives, with the exception of the JMicron based SSDs went down in performance in the “used” state. And the only reason the JMicron drive didn’t get any slower was because it is already bottlenecked elsewhere; you can’t get much slower than 0.03MB/s in this test. These are pretty serious performance drops; the OCZ Vertex runs at nearly 1/4 the speed after it’s been used and Intel’s X25-M can only crunch through about 60% the IOs per second that it did when brand new. Granted there is a new firmware out for it now. I think it is too early for SSD adoption just yet. The price point does not make it worth while when you can raid cheap drives to gether and get the same performance. I originally thought of using ssd for my cache drive until I did a little research. Besides, the bottleneck will be the network Gige! If you can hit 80MB/s on your Gige, your doing awesome. I think most of us hit 50-60MB/s at most.

    New toys

    Where do I start? When ?
  3. Same here, with the same newgroup server. Of course, if they say on tuesday they now have 300 day retention, it will take a little while to get to 300 days. Newsleecher does not search beyond 200 days. I am trying to search for things that were there over 200 days. What are my options?
  4. It does not matter what port I use, 8080, 9090, 88, doesn't make a differnce. All I get is a blank page, no errors on the http. Maybe I will uninstall and try the full package...
  5. I ignored the error for now. I see the ps -ef |grep SAB shows it is running... root 2694 1 0 22:19 ? 00:00:00 python /boot/custom/usr/share/packages/sabnzbd/SABnzbd.py -d -f /boot/custom/usr/share/packages/sabnzbd/SABnzbd.ini -s 192.168.1.55:9090 But nothing comes up when I http to it. Thoughts? This works great on my xp machine. My install was the step by step install not the combined package one, as like the ability to easily upgrade.
  6. I am getting errors when I do this: root@Tower:/boot/custom/usr/share/packages# tar -xzf par2cmdline-0.4-tbb-20081005-lin32.tar.gz tar: par2cmdline-0.4-tbb-20081005-lin32/COPYING: Cannot change ownership to uid 501, gid 501: Operation not permitted tar: par2cmdline-0.4-tbb-20081005-lin32/libtbb.so: Cannot change ownership to uid 501, gid 501: Operation not permitted tar: par2cmdline-0.4-tbb-20081005-lin32/libtbb.so.2: Cannot change ownership to uid 501, gid 501: Operation not permitted tar: par2cmdline-0.4-tbb-20081005-lin32/par2: Cannot change ownership to uid 501, gid 501: Operation not permitted tar: par2cmdline-0.4-tbb-20081005-lin32/README_FIRST.txt: Cannot change ownership to uid 501, gid 501: Operation not permitted tar: par2cmdline-0.4-tbb-20081005-lin32: Cannot change ownership to uid 501, gid 501: Operation not permitted tar: Error exit delayed from previous errors
  7. SSD are not all they are cracked up to be. Their write speeds are slower than disk, and read speeds are also a little slower. The 1.5GB Seagate drives are faster on both read and writes, and cheaper. The bottleneck will most likely be the GigE Network. I want to test network teaming soon. Also overtime, the SSD tend to lose their speed.
  8. It will be hard to beat this user community as well! With a few addons, it is hard to see flexraid compete, although the fact that it can run on windows will probably pickup a few people. I think if slax ever goes 64bit, unraid with vmware server, openSSH, unmenu, sabnzb, ps3media, hamachi/vpn, and other addons, it will be hard to beat. We just need to make it easier for the addons so end users (windows only type people) can click on a weblink in unmenu "Install VMware Server", Install "ps3Media" ... and poof, it would download a package and do the install...It might be easier than we think. Especially if we get support from all these open source folks. Add to unraid a cheap ram cache or one day fusion IO(4K$ today) card for cache and wow. I am just impatient when it comes to file transfers. So far I love my experience with unRaid, and I still consider myself a newbie, as I have only being doing this since December last year.
  9. astraweb.com Has had 240 day retention for the longest time, and are planning on 365 day retention. Astraweb Statistics Retention: 240+ Days across ALL groups - Retention is being upgraded to 365 days at the moment. Keep watching it rise! Completion: 99%+ Connections: 20 connections (Unlimited Plan) 50 connections (Pay-by-download Plan) Servers: United States (us.news.astraweb.com) Europe (europe.news.astraweb.com) Network: Level 3 LimeLight Networks Savvis Tiscali Cogent That is my point!
  10. I use both newsleecher and sabnzb. If nzbget had rss feeds and ssl, I would have no problems switching over. Love those rss feeds!!! What websites are you using to do your news searches on, and do they go back more than 240 days for searches?
  11. What are the better PC Blue rayplayers ? Firmware version? Fastest for ripping Blu-Ray to HD? Fastest for burning dvd,cd's? Any drives to avoid?
  12. Thank you for removing private data from the syslog. That is great, and will save me alot of time. Can we also have a button on the gui to zip and download the syslog file, instead of having to do a copy command to the usb drive from telnet? Second, where is the list of next features to come?
  13. Once the new Unraid beta comes out, I will try it. Beta 5....
  14. Go Tom Go! Did I say how much I love the support in these forums and from Tom's Group. Take that Flexriad!
  15. Muf, check to make sure that the 10 sata ports, none of them are on the pci bus, but go straight to the chip. Chances are that most MB today go straight to the chip. Same thing for your Gige!
  16. Drive expert has three modes: backup (raid1), Speed (raid0), normal (but only one sata connector works in normal mode I believe). My intention was to use it for cache in raid0 mode, or parity. But from my tests, I did not see a huge improvement using it as a parity drive, so for me i will become my cache drive as soon as I pickup two new 1.5 TB Seagate drives. I do not need TB of cache for my drive, but the speed is there and cheaper than two veloraptor(spelling???) 10K drives. So far I am very happy with how well the system has been performing. You should also look at the other threads where some people have their unraid using 30 watts at idle instead of 114-118 I use. Right now, I think that a single gigE might be my bottle neck. Cheers for now.
  17. I have not had any problems with drive expert, but I only tested 16GB of file transfers. 50 is good speed. Just need to bring that up a notch now...
  18. sabnzb! it even has rss feeds. There is a thread about someone building it. I will be attempting it soon. Running it on Xp right now.
  19. Nice low wattage. What kind of performance are you getting on reads and writes?
  20. Would/could it show up as a share?
  21. Well if it is speed you want the 1.5TB seagate drives are just as fast as the 10K veloraptor drives. Which Tsunami case do you have? Does it look like this one? http://lime-technology.com/forum/index.php?topic=3536.0 If it does, you can add one more drive under the drive cage by drilling four little holes. Then make your own 5-3 plate and slide it in to have 5 drives in the top 3 5.25 inch bays, plus 2 in the 3.5 inch bays, plus 1 in the 5.25 bay not used, plus the 5 3.25 inch tray, 1 underneath it, that makes 14 drives in that case. I have pictures of the 5-3 in the link below. Also check out the thread on mb and testing I just finished: http://lime-technology.com/forum/index.php?topic=3630.0
  22. It was the cable. I moved my entire rig over to a new box now. I ran out of hard drives to continue testing on this platform. It is a good size and platform, but me new build with the p5Q Deluxe/premium is much better. See post in MB section. End of Line.
  23. ASUS P5Q Premium has 10 Sata connections. I know the Deluxe version works, and so does the drive expert raid 0 onboard also works. Many people forget to count that esata connection that can be wired right back into the case with a simple esata to sata cable.
  24. Is there a posting of lowest wattage boards/cpu/memory somewhere? I have a few friends that want to build their systems next.
