Network Storage

Verb

Hi
I'm looking at the following as a replacement for my Windows 2003 Server as I don't utilize as I possibly should and think the following will be more suited.

D-link ShareCenter DNS-340L 4-Bay Network Storage Enclosure

I have been doing some reading about and I'm getting conflicted information on the type of HDD to use in it.

Will the normal HDD I have in the server be fine or do I need to use NAS HDD??

I keep reading stuff about 7200rpm & 5400rpm. Red & Green NAS drives.

What should I do??

Consider one of these instead, far better value for money, £110 after cashback:

http://www.ebuyer.com/722189-hp-proliant-gen8-g1610t-4gb-ram-microserver-819185-421

Has a much more powerful CPU and 8x the RAM of the D-link.

NB need to add an OS

NAS etc.. description drives generally mean they have been tested for 24/7 use.

This includes the drive used in say your sky box. I replaced the green WD 250 green "xxx" (I forget the words but it was something implying to use it in such a manor (as a dvr)) drive with a standard pc 750 green WD drive and have never had an issue.

Some people may say the green pc drives and the green DVR drives are exactly the same and you are paying for the certification/guarantee. However a cert/guarantee does not help you if you have a dead drive and data loss.

So I would say in a NAS just use a green cert drive and keep a backup.

I have a 320l , had it for 12 mths , sits quietly with 2 x red drives in it ,


when I first bought it I just put any old drive in it.


the CPU is not powerfull and the file transfer speed not the greatest ,




they have dropped in price , £39 from dabs http://www.dabs.com/products/d-link-sharecenter-2-bay-cloud-network-storage-enclosure-873L.html?utm_source=google&utm_medium=ppc%20product%20search&utm_campaign=Components%20and%20Storage%20-%20Hard%20Drives%20-%20NAS&gclid=Cj0KEQjw98mvBRD-_ciSovKhq7gBEiQAEvsBZz-Q3Lm5dmMXptOW2UYm7yn1i7_8O4cwLnaHPJrS-NMaAmVC8P8HAQ


any sata drive(s) will do , you can set it to go to sleep at night






green drives are low power consumption drives (eco friendly) ,




red drives are the ones for 24/7

Cycrow

The main difference between red and greens is that the reds have some additions in the firmware of the drive that helps in raid setup, for WD this is TLER (time-limited error recovery)
Which allows the device to limit how long the drive spends when there is an error, and lets the hardware raid handle it instead

Green are eco drives because they spin slower, which makes them cheaper, quieter and use less power. But this comes at a cost of performance. Access time on hard drives is less of an issue over NAS because you are limited to the network connection speed anyways, so getting faster drives have less benefit

realistically, for a basic NAS, any drive should be fine as long as it has the correct interface.
ie, dont get a SAS drive if your running on SATA or SATA drive on SAS

I_have_spoken

Ideally NAS drives should not run at exactly the same RPM to avoid a resonance that shakes the system and increases the chance of failure. Also buy drives from different outlets to avoid a 'bad batch' problem that affects all drives.

really ? do western digital know this fact?


I actually think your statement is rubbish .


however you must know better than the manufacturers of the NAS units


any chance of "resonance that shakes the system and increases the chance of failure" would be down to the manufacturer of the units , and to push this further any server units that have been built in the last 40 years would be sat on the floor , totally wrecked by faulty drives that resonate and die ,,,,,,,,,


did someone at PCWorld tell you this?

How Rotational Vibration Contributes to RAID Failure and a Need for RAID Recovery

enfield_freddy

best start ringing the manufacturers of all servers made in the lasdt 40 yrs to warn them




I notice that the statement (joke) is on a data recovery (give us your £) website?


apart from companies stating doom will happen , and your kittens will die , any other GENUINE statements to verify your stupid comment?

That article doesn't suggest that selecting drives that do "not run at exactly the same RPM" mitigates this alleged problem of "rotational vibration". In fact, wouldn't that result in beating that exacerbates the problem?
