    WD 500GB RE2 drives

    I don't have anything to say about the RE series, but I've replaced 2x 500AAKS which is the SE series in the last 2 months.... Now these are crammed in an old P4 Dell case with 2 SCSI u320 drives, and temp readings are off the chart 100*C which I have read can be false, as that is boiling temps and would cause a quick death... This all in a mdadm raid 1. Without Smartd, I would've never known, I don't know how I'll ever trust a windows raid again, I get alerts when the smart test fails, or has a read error, and next day it's replaced. what more could you ask for?

    High I/O in Linux raid as SAN?

    I'm not necessarily worried about the raw bandwidth, but more so the I/O load, i.e. if I can really use it as a good file server on PCI and gigabit, and raid-5. I suppose I can try on the PCI, and then if it doesn't work well, buy a cheap PCI-E motherboard/combo... I guess I still don't understand the layers of Linux raid, I intend to use mdadm to build the array, I just thought you had to use LVM also in order to grow the array at a later time if you wanted to.

    2.5"x4 SAS/SATA 5.25" Cage/Backplane

    Hi sorry, this was sold to a friend a long time ago, sorry.
  4. I'm building a home raid system with 3 or 4 1TB drives, and just a regular old 60$ PCI SATA II card on an old box... I want to have a high I/O file server, That when I have this mounted, I am able to to push downloads straight to it from my box, and also be extracting/compressing files at the same time. Is this something I can get from either a raid 5 or 1+0 setup? I've decided on linux raid because of it's flexibility, and It's hella cool, and I've dedicated myself to figuring it out to the point where I can recover/repair if I ever have any problems... I just want to know what to expect, whether I should just start with 1+0 or maybe I can squeeze a bit more space out with 5... It's all over gigabit network, but I won't be pushing bandwidth > 20 megs/s anyways, it's more the i/o I don't want it to chug when I'm playing movies, downloading to it, and extracting files from it... I WANT the network to be the bottleneck. Is this unrealistic to expect of this type of setup? This is pretty much all that old box is doing... file server.

    eSATA + cardbus ?

    I would stick to USB, PCMCIA is really really really old standard, 33mhz, and I believe really slow. like it's been around since 1995.
  6. very nice, is this just an ICH9 software raid? I think the uncatcheable experience I would like to "feel" is the zippiness of a OS drive. Have you used them as main OS drives?
  7. I don't know what they were thinking with the sata plugs. The cables are too stiff, and eventually YOU WILL bust one of them. Of course as long as it's just on that L Bracket, you can replace that, but having to shut down gracefully... Even internally, multiple sata cabling can be a nightmare. I've broken sata brackets twice, rendering an array useless. The clip on cables were a boon, but only to the point that they kept the cables plugged in. They actually are what broke my internal sata cage, the cable moved, and instead of unhooking, it busted the sata plug right off... so, locking cables are NOT the solution, there just isn't enough meat on those plastic connectors, really need threaded metal to be safe. If a comparable solution is available for the same or close to price, I wouldn't hesitate to do away with the internal cables, externally. Because really that's what you're aiming for. One cable, ok, 2, maybe, but when you're talking whole bundle, be very careful, as they are just plastic. I would like the plague avoid multiple ordinary sata plugs... it's not something I would do to save only 250$...

    iPod alternative

    I'm still using my iRiver H120 which is fairly old school, but it's a drag and drop system, has optical out, remote. 20 gigs. pretty large compared to the newer ipods, but battery life is great, and replaceable 20gig or 40 gig drives and battery when that wears out... I plan on staying with that... Or I think some of the ipods you can load rockbox which turns an ipod into the device it should have been (drag drop, flac etc...) Check out rockbox, or any of the non protected hardware devices, iriver used to be pretty good, but I think most have all transitioned over to the flash memory instead of the hard drive size...
  9. Is the 3210s card still available?

    Best hard drive in the $100-$150 range

    I have raptors in an Antec P180 and they're more or less silent, even with seeks. I think you'll find that decoupling will mitigate almost all of your noise... A good case is essential. It seems like a round about way to find a "quiet" disk, but the rubber grommet cage of any of the antec "lifestyle" series or the P180 are amazing. Raptors straight coupled to a aluminum/steel cage is asking for noise, but in mine, it's silent.
  11. Sorry, it is a software raid type card, nothing more than a HBA with "raid" functionality, and it is in line with the ICH9R, either software raid is pretty poor... I ran some benchmarks with HDtach, and another tool, and they all came to the same conclusion. I'll be abandoning that project, my friend doesn't want to do anymore with it, so it's a wash.
  12. I bought a 200$ LSI SAS/SATA card thinking I was going to get a decent Raid-0 array, and it stinks, only 150MB/s sustained. Intel Matrix isn't any better really, about the same. This is with 4 Raptor 150s... So what is a good card that will have onboard processing and would actually benefit If I'm just all out wanting to pay a ludicrous price (preferably under 600$) for a Raid-0 card... one that would actually improve significatly I/O coherence i.e. multiple accesses... I'm talking ripping 3-4 rar files apart which are 8 gigs each... at the same time... Would I need to move into SAS that had a higher capable i/o levels? The raptors tend to get bogged down when doing multiple items, but they're fast for the OS... but my Seagate 2.5" disks seem slow for the OS, but will tear up RAR files like they're doughnuts... sorry bad analogy, but the 15k 2.5" disks are just amazing under high i/o levels from my experience... The seagate 2.5" SAS 15k drives are 73gigs, and running on an HP E200 controller, which I am not sure if that card really helps if it's just 1 SAS drive... what about cards with multiple ports, is that ever an advantage for SAS drives if it's a single system? Can a card make up for a drive's firmware that is meant for single drive useage? like my friend bought a 200$ LSI card, and 4x7200rpm 200 gig 2.5" laptop drives, thinking that the card would be able to make use of the multiple spindles and work like a cheap database server... after all the old IBM Blades used ATA-6 7200rpm drives as a server... I know SAS is it now, but is there a card that could make SATA drives handle the load like a SAS enterprise disk? Fiber channel not necessary, this is just to try and make the nicest workstation... may have actual ramifications for work, but for now we're just trying to have some fun. Thanks in advance. Oce

    New to SCSI could use help

    Enjoy the drives, then if you are still game, save up for a new 15k drives. Sorry to be another nay-sayer, but SCSI and now SAS are Expensive! I plunged 5 years ago for 2 new 15k drives, and loved them for a few years, but I've fallen back into the SATA camp because I didn't want to put out 500$ everytime I wanted a new set of drives... Maybe again in the future... The card is key, onboard hardware will make a huge difference in raid... A good card will put you back 200-300$ yikes! so yeah... play with them, but if they're not a world of improvement, don't be disappointed, just know that it does get better, and if you do decide to pony up the money, read the reviews and pick the card and drives knowing you'll pay a ridiculous amount of money for teeny tiny storage... but it's sweet, my first "new" 15k drives made my system last for 3 years or more before anything else would compete... nothing else in the last 5 years has made me say "wow" like those new 15k drives did back in the day. Remember with SCSI cabling, if they are on the same cable, you have to number them with jumpers 0-15, the card is usually 7, so make one 0 and one 1... get the spec sheet on the manufacturer's website, and keep track of those teeny tiny jumpers because they get lost easy! Everyone gets started with "old" SCSI drives, and gets the bug, and gets more into it... welcome! (not that I'm a spectacular member or anything, just saying that we all have done the exact same thing, and you shouldn't feel by any means different).

    Sandisk 32GB SDHC

    15MB/s is still fast enough to capture full speed DVD which is limited to 9Mb/s so I am not sure about HD bandwidth, but I imagine 15MB/s would be sufficient... we're on the cusp of solid state, exciting! I am however going to dearly miss my spinning bundles of joy... "you used to have spinning things in your computer grandpa???"
  15. I have a slightly damaged SAS/SATA cage... it has dual ports for SAS and SATA, I broke off one of the sata plugs accidentily. All 3 other SATA plugs are fine and in perfect condition. I took it apart to assess the possibilty of resoldering the pins of the SATA plug, but unfortnately it's not likely without a hot air rework station... However, all 4 SAS plugs are fine, so it would work 100% for SAS, and 3/4 for SATA... nice little cage, fits inside a 5.25" CDRom slot. Goes for 72$ on newegg, selling for 40$ shipped. It was actually a friend's cage, but since I broke it, I bought him a new one. Works great, just don't flex the SATA ports horizontally!!! All original parts and packaging included. See pictures, and the new item at newegg: http://www.newegg.com/Product/Product.aspx...N82E16816119006 Note this is the SAS/SATA combo, NOT the just plain SATA version. You could possibly RMA it to Athena, their website is here: http://www.athenapower.com/ Thanks for looking, Bill
