It's been awhile since i've seen a new Raptor drive come out. I would love to see them in larger sizes - while I love my raptor (boot drive), 300GB is barely enough for a proper OS + programs any more. Can we get one in a 1TB or similar size?
At the moment I am building a new home server using a micro ITX case. Because of this there is not much space inside the case and I would like to use 2.5inch HDDs to save energy. I need at least 2 TB usable capacity and I want to use a RAID to increase the availability so it would be great if I could use 2.5inch WD RED HDDs with 2 TB each but at the moment there are only 2.5inch disks for notebooks.
Looking through Amazon and Newegg's comments on Green drives, it becomes obvious that many people do not understand their purpose. Somehow they adopt the idea of a free lunch, i.e. lower power with the same great performance as 7200 rpm drives. Of course this is nonsense because a 5400 rpm drive makes for a slow system drive. My suggestion is not technical, it is marketing. Change your online brochures to state something along the lines of: "Green drives are not recommended for use as system drives in desktops due to their slower access times. They make excellent back-up and data drives, however, and will not contribute to a heat problem even in non-vented external enclosures or laptops."
ou must start production your Hard Drives with 4Kn.
I can't start build my new computer with drives that emulate 512 byte sector instead 4k native
I knnow is because of the market where most of the user uses Windows 7, but Windows 8 and 8.1 almost two years ago, is time to start sell 4knd because Windows 8 and 8.1 deliver native suport out of the box for this
I looked at hard drives in the light of what parts of the pc slows it down.
What are the limits of disc based hard drives?
I found spin speed? Arm movement? maybe circuitry? Size of the disk?
I read a few post on how it has been tried to make them faster. Is it just cost or what is limiting hard drive manufacturers?
2 arms in a hard drive? both able to read and write at the same time?
Multiple arms so any part of the hard drive can be read from in the same amount of time?
Disc- Rotated from the outside keeping the center of the disc?
Magnetic rotation instead of motor based? mag lev stabilization? Spinning and holding from outside/middle/inside of disc? Or even roller/other based?
different kind of arms? or no arm at all? Arm that allows each layer of arm to be in whatever position from tension or other? 1 arm motor moves layer of head each head in set ways? *
Strip/other going the whole length of hard drive able to read or write from entire disc surface at once? *
*multiple arms/strips that do do don't move to cover entire area.
Better aerodynamics inside of hard drive reduce friction? Not just helium-- internal structure. Increase speed from air flow produced?
Better heat disbursement? Air flow in around hard drive?
Sealed area around disc.. Air flow around area in harddrive.. Reverse flow blow out dust?
Single surface that covers entire disc? Be able to read or write from any part of disc at once? Rotating or not? Example: Cones multiple read heads per cone/ mechanical/other redirect for multiple locations?
head head \ / \ _ / \ / \_!_/switch disc disc
Raid hard drives: Can this already be done? Half+ data on different parts of disc? 4x+/- with say 2TB drive with data placed along the disc repeated 4 times? making 4x512gb with 4 spots to read from? 3 backups?
Also what is the limit in write speeds? Multiple discs and heads on 1 arm? Write each bit of data one after another on different disc? Then put them together or however in down time?
Tenho um Wd Black Wd4001faex 4tb mais so e reconhecido pelo sistema 2 TB e o Hd so e usado para armazenamento de arquivos em meu PC mais não estou conseguindo alocar o restante do Hd que não consigo criar novo disco!!!
a standalone (non-raid) drive for desktop computer, that:
1. is meant to run 24/7 (excludes ALL your current desktop drives (blue, green and black drives))
2. has 10+ years warranty at 24/7 online. (excludes all your current offerings)
3. is huge 6TB+
optional, but also nice to have:
4. is quiet and cool and does not vibrate at all.... why would anyone put some vibrating and loud drive to their desktop? ideally everyone would use SSD, if they weren't so small and expensive. Also as I imagine, cooler and less vibrating drives should have naturally longer lifespans.
5. is affordable (Red price level would be nice)
What I am asking for is a storage drive, that lasts forever. I buy one... and need to buy next one when it's full, not because previous one died horribly to crash or started having bad sectors.
ATM using WD Red, although it's designed and otimized for NAS, not desktop. But it's the closest thing in your lineup right now after Red Pro.
We have HP Proliant 350p G8 server. Willing to enhance HDD. Can WD6001BKHG support the same? We would also like to know that if we purchase this HDD will the HDD comes with the fitment according to the server.
I would like to see the lastest (or minimum recommended) firmeware version for every drive listed somewhere.
I bought severel Red 6TB drives. There was a problem with excessive head parking in early versions of this drive. As the new drives are built into an NAS there is no possibility to use the firmwareupgrade program without dismounting the drives. As the firmware data is easely available using smart data readout it would be convinient to compare the firmware version on the drives with the actual corrected firmware revision.
I openend a case to let the FW version check. But this is timeconsuming on both sides. So a list of safe firmware versions available on the internet webside would be time saving.
The last 1.8" HDD i saw was 320GB. Maybe they can be marketed toward tablets/smartphones. I wouldn't mind having 320GB of storage on my iPAD or Android tablet with the snappy speed of an SSD. SSDs are fast, but they are expensive and drive the cost of tablets high and limit the capacity of these devices forcing users to switch to cloud solutions. Then the use of the cloud becomes another bottle neck when the users internet is slow or limited which totatally defeats the purpose of using fast SSDs on tablets and smartphones.
I have an idea to do a Black2 as an industrial item. We have customer up in the Nordic that have alot of automotive drive switching to SSD but SSD is not enough. Why not use a Black2 where you do the SSD part working as long its to cold or to much vibration and as soon as they enviromental conditions is good enough it can start moving data from SSD to HDD to get enough space on SSD?

Currently using a RAID controller to create a Striped RAID volume (RAID 0) on two seperate Harddrives is the only way to get SSD like speeds and still benefit from large capacity storage. However, at minimum this requires atleast two Harddrives, two SATA cables, and two seperate SATA ports on the PC motherboard. The benefit of doing this is the native speed of the drives is multiplied by the amount of drives striped in RAID 0 volume.
With the new SATA Express interface technology currently being implemented on the newer Intel 9-Series Platforms, PCI express is able to interface with storage devices to achieve up to 10Gbps bandwidth on a single SATA express port. The current WD HDDs will not be able to fully take advantage of this technology without the use of an onboard SSD which is usually a fraction of the HDD capacity.
Instead of using large platters to make the current 3.5" SATA HDDs, why not use multiple 2.5" HDDs (or the parts) and insert these inside of a 3.5" HDD form factor casing? Doing this means that RAID technology may be used in an internal HDD to stripe the multiple platters/heads/HDDs. Have an internal SATA express/RAID controller and then Add an 8GB/16GB SSD for disaster recovery and BSODs.
Eventually maybe striped RAID + Redundancy can be applied to this concept for higher reliability.
This concept would probably be closest to bringing HDDs to max SATA express speed (10Gbps) without using highspeed SSDs.
I have a 2011 Cisco MCS 7816 but I know that it's orgianlly a ibm system x3250 4251. So the problem is that I bought two 250 GB Enterprise class HD's product number WD2503ABYZ , when I when I go into the bios it will not see the hard drives at all, have you guys encountered this problem before and how did you resove it?
