Primer on SSD and internal hard drives

As others have noted, HDD (hard disc drives) are yesteryear gear and SSD (solid state Drives) are current technology. Another bonus of the SSD is that it is pretty much impervious to outside interference like vibration. Stick with good brands like Western Digital, and Samsung and look for read rates at least 560 mb/s for smooth playback and faster access. SATA and IDE refers to the type of cable connection that the internal drive requires and you want to make sure the drive you choose is compatible with your DAC. Since your DAC does support an internal drive, it will be set up internally to mount either a 2.5 or a 3.5 and the cable may already be installed. The DAC manufacturer may have support videos on their web site for installing an internal drive. You can usually find "How To" videos on YouTube as well. 

Ok I am assuming that you bought a streamer with an internal SSD slot... Buying one and putting it in is a waste of time because when you burn more music you have to now find a way to put it on the SSD drive that is now screwed into the slot provided by the streamer or figure out how to connect it to your computer to do it which is terrible...... you have a USB slot also I'm assuming... if so buy an extension that fits into the usb port (from ebay or Amazon) move it to around to the front where it is easily accessible... once you've done that buy a flash drive whatever amount of GB you need (flash drives are essentially SSD drives) and then put your music on there. It allows you to remove it easily and change your media around without difficulty.

There are basically three types of SSD drives which have been explained very well above... two are internal and one external and yes size does matter in this case. If you are going to use the slot provided by the streamer, it has to fit correctly and usually has a hard cover around it. The second type is open and usually are used in computers... so get the correct one.

Finally if you decide to buy the internal one (I did at first and took it out), you will realize what a hassle it is to deal with and then you probably should move to the method I use.

I use an internal SSD in my streamer which is connected to my LAN via ethernet. Both it and my PC are on the same network so moving files is simple. I can't imagine an easier way.

All very helpful responses.

Thanks so much!

Sounds like your streamer is compatible with both a 3.5” HDD/SSD and a 2.5” SSD. Both connect internally via the SATA interface (which is just the standard for connecting internal storage). I prefer 2.5” SSD cause I like the smaller form factor and I think it’s much more common.  You’ll likely find a better selection of capacity and speed with the smaller form factor. Buy the best quality, largest, and fastest (read/write) you can afford that is compatible with your streamers requirements. They are incredibly cheap now, relatively speaking. +1 @cleeds, if your streamer is connected to your network and it does not have an internal optical drive to rip CDs, you should be able to copy things to it from another computer easily (this is where read/write are important as well). You should also get better performance connected internally than an external connection via USB. I’ve had good luck with Samsung SSDs but there are many quality manufacturers. Western Digital is good as well.
