Hi would the Seagate Expansion 2 TB, USB 3.0 7200 rpm external HDD be good for putting my piano/orchestra vst libraries on, I have just recently pucased east west pianos and want it to run well, read on the seagate site that the HDD has "Built-in power management to ensures energy-efficient operation" would this effect the speed of hdd having this on the HDD

Most energy efficient hard drives will do one or both of the following
1) operate at lower spindle speeds
2) spill down when not active.

I'm not familiar with VST libraries. If you need to constantly access files on the HDD, you probably dont' want that style of HD (unless you disable the spin down features).

Ok Yes I will definatly need constant access of the files on HDD for the piano libraries, do you know how I could disable the spin down features, or do you know of any good HDD I could buy for my piano VST libraries, I have USB 3 and Esata on my laptop, am finding it very hard to find a hdd which has a 7200 rpm is usb 3 and that isnt a energy efficient drive.

What is your budget and how much space do you need (not sure if 2tb is needed or a default)?

havent really got a budget would not want to spend a stupid amount on the HDD, I dont really need 2TB would probably need around 750gb for all the VST instrument actually probably less than 750 GB although my piano vst library is 270gb and got some orchestra vsts so 750 gb would be safe size, but dont mind it being higher GB as could put some over stuff on the HDD :-D

Besides disabling spin-down in your computer's power management settings, you may also need to use a special utility to completely disable all power management. I spent many weeks diagnosing this problem, and it is now documented in the EWQLP Play documentation.
The utility I use on Windows is Drive Power Manager

You'll probably have to run it each time you reboot, and maybe if you use suspend/hibernate too.

I didn't look into if this addressed any powermanagement issues, but it is still potentially a good read for you

750 Gb of VSTs?

Goodness me.

In my youth I used to 'compose' songs using OctaMED on my Amiga computer, and store epic masterpieces on 880k floppy discs.

Will you be gigging with it? If not, the spin down thing may not be too much of an issue. It will only spin down when not used for a significant amount of time, and then it should spin up fairly quickly when you come back. A little delay when you come back to the piano after eating lunch or whatever would hopefully not be too annoying.

Another thought: I have a similar external hard drive and when you use USB 2.0 the drive does not spin down. The power saving feature only kicks in while in USB 3.0 mode. I have never used an external drive for a VST, but I suspect USB 2.0 may be sufficient. Anyway, something to look into.

In my case, it was not even usable for casual home use. I had disabled spin-down in Windows, yet I still had problems. After a relatively short period of inactivity, the drive would enter a partial shutdown of the electronics - not a full spin down. This is why I had to use that aforementioned utility to completely disable even this partial shut down.

Greg.

I see. Very annoying indeed. Thanks for the additional info.

Is it your opinion that USB 3.0 is necessary? I mean if not, you could go cheap and skip the power saving.

Something like this.

Yes, I’m using this drive and it’s ideally suited for your purpose with a capacity that gives you some ‘future-proofing’ for even bigger libraries. I’m sure you know that the USB 2 spec limits data transfer rates to around 25-30 mb/sec so the 3.5 inch unit inside the Seagate capable of sustained reading at around 80mb/sec is overqualified. In any case, most sample-player engines seem to manage pretty well with this level of performance (25mb/sec) even with high polyphony – the acid test being a long piano gliss with the sustain pedal held. The corollary to this is that almost any modern external USB2 hard drive will do the job well enough so just go for best price per megabyte + quality/reliability.

- ah, apologies, should have read the Q more carefully. Spin-down hasn't yet been a problem for me but maybe that's because of the way I work where there are few delays between access. Not sure of the spin-down time.

Probably not necessary for playing solo piano, no. I found the East West writeup: See section 5.6 here: http://www.soundsonline.com/Support/knowledgebase According to them, it's a SATA function, so it's nothing to do with USB 3.0.

I'm using an internal SATA drive on my laptop.

Here's another option for you.

I've used this connector to transfer data to my laptop from old IDE drives and it works well with most formats though I haven't tested the transfer rate

http://www.amazon.co.uk/IOMAX-SATA-..._3?ie=UTF8&qid=1334906803&sr=8-3

- then buy something like this (but check the power manangement issue)

I just remembered something else about the drive power management problem. The reason it caused problems quite frequently is that even during playing, there can be long periods when the disk is not accessed at all. This is because of the dynamic sample caching that occurs in EWQL Pianos (and most disk streaming sample players, I think). I.e - in addition to always storing the attacks in memory, it will also attempt to cache a greater extent of the individual samples - samples which have recently been played. It tries to minimise the disk access as much as possible.
