Can anyone comment on the reliability and general performance of this 2 bay SATA DAS enclosure: http://www.cwol.com/serial-ata/esata-usb-raid-ds3rpro.htm It seem to be a generic make since its got multiple labels on various websites.

How do these consumer NAS boxes handle file locking? ie. two or more clients trying to modify the same file?

Not sure if this is the thread to ask but I couldn't find another one that was more suited. Recently I bought 2 raid5 DAS boxes and both have issues with my machine. They are both based on the Oxford 936 chipset and seem to be the best in their class. One is the OWC Mercury Elite Qx2 http://eshop.macsales.com/item/Other%20World%20Computing/MEQX2KIT0GB/ The other is a Raidon GR5630-4S-WBS2 http://www.newegg.com/Product/Product.aspx?Item=N82E16816142003&cm_re=raidon-_-16-142-003-_-Product The hard drives I'm using are Samsung HD204UI 2TB drives which have all passesd a full surface scan with Samsung's ESTOOL and a low level format. The machine I'm connecting these two boxes to is a Shuttle SP35P2 Pro which has an Intel ICH9 sata controller running in ACHI mode. The Shuttle has the latest BIOS. I also did a fresh install of Win7 Pro 64bit and also installed the latest Intel sata drivers (~march 2010). Whenever I attach these boxes to my machine via esata, windows shows them as 1.4TB disks even though they should have ~5.5TB with 4x2TB in raid5. I made sure that any 2TB limiters were not enabled. However, if I attach the units via firewire, I see them with correct 5.5TB size and can format them (GPT of course). When I reattach them via esata, they show up with the correct 5.5TB volume I made over firewire. Here's where it gets screwy. I can write up to ~2.5TB to the volume fine over esata but when I go over that the whole array will stop responding and I'll be forced to power cycle the raid box. Both boxes don't report any kind of error or disk failure when this happens. When I remount the array, the partition is just gone. I can predictably do this over and over so its not just a one time thing. Now I'm hesitant to get another box because I'm not sure if the problem is with my ICH9 or something else. Any thoughts? I've kinda got my eye on the new 2nd gen Drobo S but its hella pricey.

Hopefully some of you would find this amusing. I started a project to keep me busy by upgrading some older Core2 machines for shits. One thing that stood out was external IO. This is a Dell Optiplex 960 SFF so it has eSATA natively but eSATA is rare and a chore. I looked into adding USB 3.0 but options are limited because the mainboard only has PCI 32bit expansion (133MB/s paper spec). I found some cheap Startech USB 3.0 PCI cards for $20 direct so I went and bought one and here are the results. C2Q 9650 8GB DDR2 Intel Q45 chipset Windows 8.1 64bit (bonus Windows 8.x has native USB attached SCSI -UAS- support) Here's the IO chain: Samsung EVO 840 500G (should max out PCI 32bit bus) V Seagate 2.5" bus powered SATA > USB 3.0 card (ASM1053 controller) V Startech USB 3.0 PCI card(Renesas D720200AF1 PCIe > Pericom P17C9x PCI 32bit bridge) Sequential R/W speeds are ~100MB/s:73MB/s respectively. A bit shy of the 133MB/s paper spec for 32bit PCI. Still, not bad especially considering this is better than FW800 which would still require an additional card for most systems and USB 3.0 is more ubiquitous now anyway and is backwards compatible with USB 2.0. edit: Also the PCI USB 3.0 card has a 4 pin molex connector for power but with it unplugged the card can still power 2.5" 7200rpm spinning drives so I don't think its necessary to have it plugged in at all since anything requiring more power will most likely have its own power supply anyway.

I'm looking for a NAS that can run transmission or some other torrent app with a web interface (transmission is still king right?). Right now my local Fry's has the WD EX2 4TB for $250 on sale which I think supports transmission. They also have the ReadyNAS 104 diskless for $130.

Umm, so how are you supposed to deal with a NAS hardware failure? Not a drive failure but an actual hardware failure of the NAS? Can you pop the drives out and read them in some other device? What if it was in a raid?

I have a WD Live Plus media player with a HDD inside it. Does anyone know if I can mount a share on this(or any other) media player so that my NAS can either directly download torrents to that mount or sync to that mount? Right now I'm just streaming files from my NAS to my media player but since these files are more or less disposable I'd rather have them live on the media player and free up the NAS for other stuff.

So what are some use scenarios for iSCSI? Is it literally to move a storage volume so its not physically local to a host? Less overhead than using file sharing with access restrictions if only 1 host will ever access that volume? Sorry if I'm getting it completely wrong here.

I got a cheap WD EX2 at Frys and its my first NAS. I like it in that it hasn't done anything I didn't want it to do and doing basic things has been pretty intuitive and the web UI seems to be decent. I'm thinking about going up to a 4 bay NAS. The WD EX4100 seems tempting in that it would be very similar to my EX2 as far as interface. My only gripes are that it only has 2 USB3 expansion ports and the power supply is an external brick vs internal. Also I'm not sure if its CPU/mem are any good for its price class. Just looking for any recs given I like the WD EX2.

Skandranon posted:What are you planning on doing with it, beyond a 4 disk array? What is it you need more than 2 USB ports for? Good question. I want 4 disk so I can have more storage without resorting to bigger disks in a 2 bay although now that I think about it I like the portability of the 2 bay. The USB expansion was to keep externals hooked up for backups and also any data I don't really care for like movies. I guess I can live with 2 USB ports. 1 for backup and 1 for movies.

Also, why is it so slow copying from the NAS to an external attached to the NAS? I'm SSH'd into my WD EX2 and rsync'ing from the NAS raid1 to an external USB3 single drive. rsync is reporting 15-20MB/s.

Well my home is about half PC and half Mac but HFS is only Mac and I don't really care for PC 3rd party HFS support. NTFS seems like a better choice given OS X can at least read it without additional software. Although I'm not sure I'd get any better speeds with HFS on the NAS though.

I think I found the problem why my NAS>USB3 speeds are so slow. It's not the file system. I'm getting ~17-20MB/s for NTFS and EXT4. However, the CPU goes right up to 100% during the transfer so the bottleneck is the CPU. NAS is a WD EX2.

Anyone venture to guess which of these 2.5" HDDs is more reliable/better than the other? Segate/Samsung Spinpoint M9T 2T (9.5mm 667G/platter 32M) vs WD Green WD20NPVX 2T (15mm 500G/platter 8M) Both are found in common consumer 2.5" externals. The WD being thicker due to lower density.

Are disk'd NASes warrantied for the disks inside? If a disk dies within the warranty period I guess its best for an end user (read: not business) to backup from a degraded array and send the whole thing back to get replaced? Also, do any of you guys do surface scans/low level format scans on new NAS drives before putting them into service? Is it necessary? What do big enterprises do when building storage? Obviously there's a time cost in scanning 4/6/8TB drives.

SamDabbers posted:As I said above, I run the badblocks utility for Linux (it's in the sysutils/e2fsprogs port for FreeBSD), and a SMART Long Test on all my new drives. The badblocks utility writes every sector on the drive a few times with different test patterns and reads each one back to verify. If either test fails, or SMART data shows uncorrectable errors/reallocated sectors after a full badblocks run, then I get an RMA. I test an entire batch of new drives in parallel, so it only takes a day or so to burn in a full array of multi-TB drives, and another couple if you need to do an RMA. For a NAS that you'll be trusting with your data for at least a couple years, an extra day or two to make sure you're starting off with solid hardware seems like a no-brainer. Neato. I wonder if my NAS has those tools. Probably not. Does badblocks run on the raw disk? edit: Ha, my NAS has badblocks tool. WD EX2 btw.

Interesting math. Seagate/Samsung 2TB 2.5" 9.5mm drive is 30.14GB/cm3 Seagate/Samsung 8TB 3.5" 25.4mm drive is only 21.23GB/cm3 So the 2.5" drive is by volume 42% more dense than its 3.5" cousin. So in the same unit volume as the 3.5" drive the 2.5" can achieve ~11.3TB. Of course density isn't everything but fun to know.

I can get into it fine from a local device and am prompted for my credentials/can ping the box remotely, but it won't take either the password nor a SSH key. As an aside, if anyone else has this box, would you be able to recommend how to prevent everything in ~/ from being deleted when the box is restarted? Get one for cheaps? Did you turn on SSH in the web panel? Did you set the password in the web panel? AFAIK, you can't prevent ~/ from being cleared so I don't keep anything there. Its lovely but I can live with it.

I can't tell if hosed up my drive. I ran a ATA secure erase on a Samsung 2.5" 2TB spinner from Parted Magic for shits and it was saying it would take ~360minutes and that I shouldn't try to stop it. I've never run a secure erase on a spinning drive before but I always thought that nothing can hurt them functionally. Well I was impatient and forcefully killed the secure erase. Now I can't seem to partition/format the drive. I haven't tried using the Samsung/Seatools yet but is force killing ATA secure erase on a spinning drive enough to brick it?

I guess there were some OEM(?) 1TB PATA drives? The largest I found before were 750GB segates which I own 2. http://www.ebay.com/itm/1TB-IDE-40-PIN-PATA-UDMA-133-Western-Digital-WD-Caviar-Green-HDD-1000GB-NEW-/301578890078?hash=item463780ab5e  I can't seem to find any documentation about this drive on google though. Looks like a retro fit SATA drive but still, no record of it.

At UHD res and 16bit depth and 24fps you're looking at 5-6TB of compressed tiffs for a 90minute feature mono only. Double it for stereo. The seagates are just for small 4-5 bay DAS devices to shuttle material between vendors and what not. The actual backend storage is much more robust that I don't manage.
