Hi. I'm hoping some people here may be able to offer their opinions on my question re the best drive to go for in my situation.
I have a HP Proliant Microserver, which I wish to buy four 2TB discs for.
I was going to buy some Seagate ST2000DL003 drives:
But I have also been recommended to consider paying a little more (approx £20 extra per drive) to get this other model. The Seagate ST2000VX002
The latter drive has a 5 year warranty and says it's made for 24/7 usage which all sounds good. Has the same number of Platters, Cache, 64MB Buffer etc.
But if you read the page it does say:
Video surveillance digital video recorder (SDVR)Video surveillance network digital video recorder (NVR)Direct-attached JBOD video storageNetwork-attached JBOD video storage
The SV35 Series hard drives are engineered for rigorous 24x7 video surveillance systems, offering tuned performance, high capacities and durable reliability required for the high-write workloads of video surveillance systems
It does not say, suited for Server/NAS applications.Should I be concerned about any of this, as it "Sounds" like a more reliable drive with a longer warranty that's built to be on all the time, as opposed to the other which is just a "normal" hard drive for PC's in general.
I'm having a LOT of trouble finding out anything about these ST2000VX002 models
I didn't want to pay extra and then find they are not really suitable for a NAS device.
Thanks in advance for any thoughts on this you might have

The price, acoustics, seek times, and warranty of the 2TB SV35 are much closer to the Barracuda XT than the Barracuda Green. I think that is a better comparison. Newegg.com has the three drives for $80, $120, and $130. There is a lot of information about the Barracuda XT around to help you make a decision.

Thanks for that. I shall read that link.
DL = Entry Level
So the Seagate ST2000DL003 that people are using perhaps in a home server is not even up to the grade of a middle grade or premium desktop grade. Let along anything higher up the scale.
It does make you wonder just how much you should trust such drives if they are the lowest grade they make.
If the VX = Surveillience (which I believe they say is built for 24/7 work) you would THINK it's built better, esp as it comes with a 5 year warranty AND is built for continuous use.
I have read there are or can be some issues with using the "green" disks, such as the popular Seagate ST2000DL003 due to all the power saving things it does.
Basically I just want to make sure I purchase the best value for my money

The drive names have different tasks in mind, none of the drives are weak, but the higher end ones either spin and seek faster or are built to withstand many constant hours on, probably by improving their thermal abilities.
If you want a little tip, mount any HDD in a fan assisted case bay, a drive with air going across it will stay at 20-30 degress, one without will idle at 35-39 and after work it will burn your fingers removing it. hth.

Thanks for the replies.
Both the DL and the VX drives seem very similar in general.
They both have the same 5900 RPM, 3 platters, Voltages, 64MB Cache
The only "REAL" differences on the spec sheets seem to be:
1: The VX is 0.6 Bells louder (2.7 compared to 2.1 on the DL model) I'm not sure what difference that makes.
2: The VX has a 5 year warranty as opposed to 3, and they say it's built to stand 24/7 running.
3: The VX has MUCH faster read and write seek times of 8.5-9.5ms compared to 12.0-13.0 on the DL model. That's around 40% faster, which is a lot in anyone's books.
4: It's about 33% more expensive (but that's only £20 in reality)
I'm still wondering which would be the better NAS drive.
The more expensive VX with the longer warranty, 40% faster access times?
Of the DL which promotes itself as the "Green" drive, and yet seems to be pretty much the same drive in many respects. Apart from being 0.6 bells quieter, whatever that means in reality?

Where I go shopping the green is £60, the XT is £135, if you get better deals then go for the higher model, but unless you are like Gamespot etc with servers that are constantly being asked from, I wouldn't bother, the green will probably serve you just as well as long as you feed it good reputable power and keep it cool, I think cooling is the major factor here tbh regarding longevity and lack of hanging etc.

As you say, some things just don't seem right.
Actually the link you posted to here: http://groups.google.com/group/comp.sys.ibm.pc.har
About drives made for surveillance has pretty much put me off the VX model which is good, as I needed something to persuade me one way of the other as I was on the fence over this.
I'm 99% sure I'm going with four Seagate Barracuda Green ST2000DL003 drives now.
