In Reply to: RE: Power Supply for External SSD? posted by AbeCollins on November 07, 2016 at 14:07:09
Thanks Abe, I think that the solution in your final paragraph is a particularly practical one.Just for the record, I haven't actually got a Samsung T3. I just used the image of one to show Paco what I meant about the connectivity of these devices. Still even if I don't buy that Sammy I daresay I will get a similar device. At the moment I am just looking at how to do it all as, unlike using HDDs, the cost of SSDs of a usable capacity for my music library is still such that I can't afford to just take a punt and write it off if unsuccesful. The idea is to get rid of disc spin up noise without the complexity of going down the NAS route which , aside from this specific issue, has no other clear benefit for my limited requirements.
I am, however, still left with an unknown. If, as is pretty clear to me, the cable from the drive to my PC makes a large difference to the end sound, how great is the effect going to be of routing the data via a hub or other solution? The only way to find out seems to gamble and try it.

if your main idea is just to get rid of hard disc spin you really don't need to use SSD:
all you need is using Audirvana, or similars! they put your selected music from HD onto RAM before playing,
so when you are playing your music it comes from solid memory and nothing is spinning!... :)
Thanks again Paco. My problem isn't hard disk spin but spin UP. This still occurs when playing from memory (as I do) as the player does not store an entire album but loads a track at a time into the memory. So, towards the end of the preceding track, the player requests the next track to load. This causes the hard disk to spin up and a brief (under a second) noise as it does so. Thereafter the disk ceases to spin.
I use JRiver MC 22 as my player. One feature ( yet to be implemented) in the specification for 22 compared to 21 is that an entire album will be loaded into memory. Once an MC 22 build is issued with the entire album from memory feature my problem will be over. However with JRiver the specifications for a new version may be more in the way of aspirations at the beginning.
you're very welcome! what you say about JRiver astonishes me! with Audirvana
i never experienced any noise at all!! when a track is finished it downloads the next one
in total, absolute silence, and very very fast; you should try! they have a 15 days free trial...
No, the noise doesn't come from JRiver. It is a noise from the mechanism of the Seagate HDD as it spins up when it receives a command to send data for the next track. That is why I want to replace the HDD with an SSD. JRiver itself is a great piece of software.
I am very pleased for you that you are happy using Audionirvana. However it cannot be appropriate for me as it is an application solely for Apple Mac (or , more precisely, OSX). My operating system is MS Windows 10.
i see... i didn't know those drivers are noisy... my iMac internal driver is silent, as far as i'm able to notice... anyway, good luck with your investigation!
I was under the impression that you already owned the T3.
- Buy a bare SATA SSD, not one that is already in a case. Then buy your own external case that has an external 5VDC power jack. Example linked below, but there are several others to choose from. It will house a standard 2.5" SATA SSD, has a jack for external power, and a USB 3 port to attach to your PC.
- Or buy a powered USB 3 Hub
Thanks again Abe, you are a gentleman.
I have subsequently spent the last 45 minutes on line looking at just about every case for 2.5" drives with USB connection that is available in the UK. I cannot find any that take external power. All power the drive via the USB bus. So this result just takes me back to my initial problem.
The case that you kindly linked is not available via Amazon here. The nearest equivalent that they have is , again, USB bus powered.
I am only able to find cases/caddies for 3.5" drives that take a dedicated external power input. As far as I am aware SSD drives do not come in 3.5".
So , it's now time to look at powered hubs :-). However I am not keen on this as I suspect that the hub itself and the additional links it entails will degrade SQ.
Maybe I'll have to end up using NAS with , perhaps, the new dCS network bridge or maybe buy a Rossini ;-).
Many enclosures for 3.5" SATA disks will accommodate 2.5" SATA SSDs through the use of adapter brackets. And most 3.5" enclosures come with a power jack for external power, but it will be 12v instead of 5v. Some will come with the brackets, or you can buy them separately. They're just inexpensive brackets to fit 2.5" disks in an enclosure made for 3.5" disks.
Search Amazon for:
3.5 sata to usb case
3.5 to 2.5 drive bay adapter
I don't think that these dedicated usb2/3 ssds are good deals. First, you may not be able to pullthe disk for use as Sata or pcie devices.
Second, you'd probably get a speed limited controller which is cheaper for the vendor and
Third, you loose the ability to power independently.
I'd go for a regular ssd in a high quality box bought separately, with usb, eSata or Sata and separate power input. There will be a cheap regulator inside but this will be helped by a good external 5V power source.
