The ODROID HC4 with OLED + RTC Battery  - which we call "The Toaster" - is an updated and much more powerful new revision of our popular Home Cloud line of NAS server systems. The "toaster" form factor accepts 2 x 3.5”, 2 x 2.5”” mechanical HDD or SSD storage devices, or any combination of the two.

ODROID-HC4 accepts 2 x 3.5” or 2 x 2.5”” mechanical HDD or SSD storage devices. You can also mix and match using one mechanical and one SSD. With our implementation of Linux LVM or mdadm Soft-RAID, you can combine two disks in RAID 0, RAID 1 or optimize IO with a large disk using one mechanical drive for the storage, and an SSD for disk caching.

This is the HC4 unit with RTC + OLED. It is pictured with 2x SSD drives (not included) and features a dual slot mechanism at the top allowing you to plug in either a SATA 3 SSD or a SATA 3 HDD drive.  This includes an RTC (Real Time Clock) and an OLED display built in.
