USB vs eSATA connection

by Comus » Sat Jul 15, 2017 9:17 pm

Hi folks,

Newbie here; first post.

I've read that the internal drive in the BDP-2 is connected via eSATA. Would this mean, then, it would be preferable to connect external drives (that have both USB and eSATA outputs) via eSATA as well? I have an OWC Mercury Elite Pro SSD that offers both options; it also has its own power supply.

Q: Would a self-powered external SSD connected via eSATA offer better SQ than via USB? [Btw, I mention 'self-powered' only because I presume (perhaps erroneously) eSATA drives don't draw power from the host device via the cable, as with USB?]

Thank you in advance.

Cheers
Comus

Hello

Yes any device using esata would require an external power source, however if you intend to use the internal sata hookup a power source is provided. There shouldn't be any noticeable difference in sound quality due to how the BDP operates.

Thank you, Chris.

The ONLY reason I'm considering an external eSATA drive is because (from what I've read elsewhere in this forum) it's seems much easier to transfer/rename/edit/delete folders and files by plugging the external drive directly into my Mac, as opposed to trying to accomplish this with the internal drive. Is that a correct assessment? If it is, I'd much rather take the easier route. (Easier for me, anyway, as I'm an incorrigible Machead who doesn't know how to even boot up a PC; given that Bryston's stuff is Linux(?)-based, I'd rather avoid any PC-like protocols/procedures.)

Thank you.

Cheers

Chris,

Btw, my reasoning for taking the eSATA route as opposed to USB [my SSD offers both options]:

I figured there was good reason (in terms of achieving best SQ) Bryston decided to connect the internal HD via eSATA. If I went in via USB (with or without an external power supply, split cables, etc,), the signal would necessarily have to undergo a conversion, and end up on the same board the internal SATA drive is connected to? If this were indeed the case, I reasoned that since it's 'generally' accepted that the internal eSATA drive yields the best SQ, I would achieve exactly the same results by connecting via external eSATA, thereby obviating the need for USB-to-eSATA conversion. Does this make sense?

Thank you.

Cheers

If this is your goal my suggestion would be to get a USB drive and format it as exFat. USB drives are hot swap capable where as the esata is not and using exfat should provide high reliability.

First the 'e' in eSata stands for external, internally it just known as sata and sata happens to be a drives natural interface. The only difference you're likely to notice is the time taken to update the library and the earlier mentioned hot swap limitations.

Hi Chris,
I ve decided to install the internal drive. (I currently have a SSD that's connected via USB, which I'll also keep.)

The new Samsung EVO850 SSD arrives today. From all that I've managed to gather online, it appears the new SSD would need to be formatted to "Fat 32" on my Mac BEFORE installation in the BDP-2. Is this correct? I was under the impression the formatting was done after the HD is installed, and the BDP-2 connected to the Mac. Please advise. Thank you!

Cheers
