    Put them in a server and run some sort of SDS on top of it like Nexenta. Fun learning experience and gets you a cheap SAN.

    Note the three years in between though...they've been surprised by the interest in the platform I think. Now, if WD could just get those 2.5" Reds up to 2TB in a 9.5mm...

    Long-time watcher of StorageReview, but I registered just to be able to comment on this review. An excellent review, though your testing seems a bit high-end for the likely intended usage. I'd bet the majority of the target users for this SOHO device won't have a backbone that supports iSCSI or even dual-port aggregation. As you point out, 2-10 users in a casual / small office setting or for home use seems a likely audience. Such an audience would be much more likely to have an entry-level GbE switch as opposed to a managed backbone that costs 10x more. To that point, I've used the entire line of BlackArmor devices, and there are three critical issues common to them that seem to be repeated with the replacement Business Storage line... none of which are mentioned in the review, but they may not impact everyone so I'm not sure they necessarily bear mentioning up-front. 1) Performance. You obtained okay numbers in your testbed, but as summarized above, I doubt you'd see that infrastructure in the wild. I'd suggest you at least pair it with testing results from a cheapo GbE switch using a single LAN plug and simple Windows file sharing / disk mapping. Unless the BS line has markedly improved from the BA line, you'll see performance on the order of 15 MB/s read, 10 MB/s write. Horrendous for anything but backups, really, which is all I use my BA boxes for. Also, I recognize that there's a massive disparity of price points and target audience, but I get 110 MB/s--TEN TIMES the performance--from my Synology boxes, and 50-70 MB/s from my Drobos. And that's on a cost-conscious backbone of entry-level GbE switches using one LAN port per device and simple, iSCSI-less file sharing in Windows. There's no comparison at all. 2) Compatibility. Massively overpriced with disks, the BA and BS line are very reasonable when purchased diskless. I've used Buffalo, Seagate, Synology, and Drobo NAS boxes in small-business and personal settings, and diskless BA/BS boxes are far and away the cheapest way really of adding reliable (but not fast!) NAS storage in such contexts. But these NAS boxes only support Seagate disks. True, this is a Seagate device, but it seems as though someone had to intentionally code a rejection routine into the firmware, which is just kind of an obnoxious move. In addition, some of the compatibility notes for "certified drives" listed for the BA line are flat-out falsified--the diskless BA 400 will simply NOT work with the 1.5 TB desktop line of Seagate disks, period. 3) Risk. For those who know what they're doing, these are fairly easy boxes to deploy, and the web-based UI is second only to Synology's in my experience. But it's easy, far too easy, to make a catastrophic mistake. For example, if you set up a BA box using one LAN port, and then try to plug in a second LAN plug, it will not only not work, but it has a strong chance of corrupting the entire array, forcing you to not only lose all data and set everything up again, but in order to even begin to do so, you must eject each disk individually and reformat it using a separate computer. Otherwise it won't set itself up. Now, much of my comments above are from my experience with the older BA boxes, but I'd like to know if those issues have been resolved with the replacement BS line. Anyway, as always, I love seeing info on Storage Review.com so keep up the good work!

    You're almost right here. What's missing is that copying small files, even from the same directory, will automatically include some random access too. The files being read may be spread across the disk, they may be written different locations, filling up holes in the current file structure (what ever the OS see fit) and the MFT may be accessed. That's why multi-threaded copy for higher queue depths still improves throughput: the disk can arrange the accesses better through NCQ and can reduce access times. BTW: if the folders you're copying are often the same I'd look into incremental sync'ing with e.g. DirSync (nice freeware). Not sure it can increase QD, but it certainly saves time not to transfer untouched files again. And I'm not a fan of buying large SSDs for storage, that's often a waste of money (IMO). I'd rather use the SSD for temperary storage and as automatic cache. If you're concerned with many small files an SSD would be ideal. And if the SSD cache also buffers writes you may see a massive speed increase. The cache capacity would also be huge compared to the amount of storage required for small files MrS

    Ultimately the storage-centric R730xd offers new degrees of flexibility for those who want to keep storage as close as possible to the compute layer. The chassis has a lot of potential in SDS situations too, something Dell likely had in mind as they continue to innovate generation after generation with leading storage server solutions.

    What Progressive Capacity means is that WD can use odd-formatted platters in drives in boxes of 20 drives to hit a specific capacity point, like 1PB. The capacity of the drives within that box to hit a 1PB target are somewhat irrelevant, data centers looking at this class of drive often are not using RAID and are more concerned about capacity in a specific footprint.

    To be fair they're not claiming this would ship in mass quantities to end user stores. I concur with Brian in that it's probably SMR and by "support for archive workloads" they actually mean "don't try to use this for anything else than archive workloads". By "consistent enterprise-class performance" they probably mean "it's always slow". If it was any better than this they surely would have said so. That's not to say the drive wouldn't have its place.. but I think it may actually be good to limit their availability for now. BTW: it's no excuse, but Seagate has been soft-launchnig drives for years. Sometime retail availability took a full year! I see no reason to get any more tired of this than in the past years. MrS

    Sadly, reinstall. It's a massive pain if you have a lot of apps, but the end result is worthwhile.

    I think eventually geometry will be layered so tight together sectors will suffer magnetism bleed. 0s next to 1s will flip, etc..... Arms and pivot points will be tight and accurate for only so long. Electric motors will get sloppy stepping after a while... Sent from my rooted HTC Supersonic using Tapatalk 2 Pro

    Yeah, we know we need to work on the charts to make them less confusing to read in a row, thanks for that pointer. The drive isn't intended to be in heavy write use cases, per our disclaimers in the review. That said, I'd take our real application tests as a better indicator of performance than synthetics. One other comment I'd add is that Pure Storage used to use SSD 830s in their AFAs. Not sure what's in there today but we've seen a lot of high-end client drives show up in AFAs or Hybrid Arrays.

    We have some new Areca cards in for testing, we'll see if it's best Looks a lot like LSI.

    What is a S.M.A.R.T diagnostic saying about the drive? Check the Hard disk manufacturers' site or use UBCD for hdd diagnostic tools. The tools may not work so well if the hard drive is in a usb enclosure,so you may have to put the hard drive back into the orginal laptop and run the bootable cd/usb tools. http://www.ultimatebootcd.com/ If it comes back clean, the OS(Vista) is corrupted. You will need to look into repairing it or just reinstalling it(sometimes best option). It it gives you a specific error message during loading, do some research on with Google. If SMART fails, then it would be time for a new drive. You may also want to consider a SSD. SSD VS Hard disk(HDD) guide.

    I haven't noticed the file naming issues you are referring to, although I'll admit that my primary usage with the Synology units is from Windows/Linux PCs. I do use a MacBook Air at home to one though which I've never encountered any issues with. I can use a thunderbolt to LAN adapter to see what the file transfer speeds would be like back and forth. The DAS storage options for the Mac Mini are somewhat limiting. The Drobo units are painfully slow, and the Lacie/WD/etc units that attach over thunderbolt while incredibly fast are limited to RAID0/1/JBOD through software RAID in the OS on your mac. I'd prefer going with RAID6 to capture more usable capacity and protection for such a large dataset, which is something the NAS will provide.

    You're already sad with the Drobo performance, trust me, it's not any better now, so I'd mark that off the list promptly. In terms of NAS vs DAS though, how many people or devices will need to access the storage? Do you see any benefit from the NAS features like remote file access, etc or do you really want the performance DAS offers by comparison? Both the LaCie and G-Tech products are very nice incidentally. There are also other options form the likes of Caldigit and others who have quality products as well.

    Saw a post somewhere (was it here? Or somewhere else?) showing they had opened up a Seagate 2TB 2.5" external or something and it had a Samsung M9T inside with a standard SATA connector.

    Your Toshiba 2.5" HDD appears to be a standard laptop SATA "form factor": as such, there appears to be an adapter affixed to that Toshiba HDD, which mates with the data and power connectors on your laptop motherboard. In your last photo above, just count the pins. BIG CLUE was your statement that you just "drop it in": that appears to be the geometry implied by those 2 rows of contact pins. MY SUGGESTION / FWIW: remove the Toshiba entirely, and check to see if you can remove the plastic adapter: it may be screwed on, or it may be a "press fit" (as we used to say, when I was a carpenter). "Press Fit" means NO FASTENERS (nails or screws etc.) I'm making that suggestion because I upgraded a laptop for a friend, about 5 years ago, and it also had the same type of adapter: I merely removed the adapter from the old 2.5" HDD and installed that adapter on the new 2.5" HDD, and the new HDD worked fine. 2.5" SATA SSDs have the same connector geometry as 2.5" SATA HDDs. Therefore, if that adapter can be removed you should try attaching it to your 2.5" SSD, being very careful not to bend any pins. Hope this helps. UPDATE: Here's what your Toshiba MK1665GSX HDD2H85 looks like, as manufactured by the factory i.e. withOUT that plastic adapter: http://www.geeks.com/details.asp?invtid=MK1665GSX-NDW

    I formatted a 12TB spanned volume with exFAT once. Worked perfectly! Windows GUI won't let you format HDDs exFAT, but you can use the FORMAT command in CMD to do so.

    Format the drive as exFAT. exFAT supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K, 128K, 256K, 512K, 1M, 2M, 4M, 8M, 16M, 32M.

    Synology has announced the launch of the RS3614xs+, the latest in their XS+ rackstation line. The new RS3614xs+ provides enterprise features at SMB prices so that small businesses can now take advantage of performance, scalability, and the virtual storage options of VMware, Citrix, and Hyper-V all the while still offering general-purpose storage that businesses require.

    Did you consider just using a NAS and throwing it in the basement or wherever your router is?

    Also it may be cheaper to buy two UPS's (one for monitor, one for computer) than one big one. If you are borderline your existing UPS where removing the 50W of load of the monitor will make it work, then a second cheap UPS may be better than trying to buy an extremely expensive larger one.

    But how is the cached used in long sequential operations that would allow for higher speeds without quicker throughput through the heads? Thanks The only thing missing is a hybrid drive option with this drive.

    Hiya, just tried entering info for some drives I have spinning accross different systems, but I am in a dead loop: - RS tells me to login or register, I click on register and go to the forums, where I am logged in ?! - If I click on RS, then I am again not logged in... Browsers tested: IE 8 and Firefox 15.01 on win7 pro x64. Account created literally an hour ago. However no e-mail for activation came through ...
