The Wally with EHD will be continuously writing because of buffering. I wouldn't even dream of using SSD with it.
And SSD's have other drawback's compared with HDD's, especially as an archive
medium. I would stick with HDD's regarding Dish external drives, but the quality of external
HDD's today from legacy big brands is pretty bad these days, but I would suggest the WD Purple (opps, WD Purple is not an external HDD, but maybe the solution is to use a docking station--can that work as a Dish external HDD?)
because they do quite well as they are designed to take a beating with something like 20+ cameras (channels of video) and they perform well with 4 and 6 tuner TiVo's that can end up buffering 24/7/365 if the TiVo "Power Saving" feature is not used--and many do NOT use that feature--also the WD Purple has lasted me years and WD Purple are still CMR/PMR, as opposed to most consumer HDD's today being PMR withount the manufacturer stating so. The external HDD's these days seems a crap-shoot, unfortunately. I see nothing bad posts of rotten experiences these days. I am at a loss of what will replace my external HDD's I use for network access.
The SSD's are for more sensitive to heat and can lose efficiency quite soon or even just die
, but even worse is the discovery of inferior chips inside the most recent SSD's that do NOT meet the speed/efficiency specs claimed on the specifications. The theory is that the microchip shortage may have caused ALL the manufacturers of SSD's to use inferior chips that cause under-performance rather than have no stock of SSD's to sell. After all, if one SSD's brand does it, than all the others have no real choice but to follow, and this includes the vaunted Samsung SSD's, as well. I'm glad I got my two Samsung SSD's before this current chip shortage. SSD's do have some good uses--especially the Samsung's, but they have not completely
outdone HDD's yet. I would suggest one keeps an HDD backup of any important data saved on an SSD.
