AVTech DG1007A home surveillance system, has a 1TB regular platter WD Purple 10PURX hard drive 64 MB cache. When HDD goes south, is it a good idea to replace with a SSD instead? I'm thinking a Samsung 870 series. The WD and Samsung both have 6Gbps rating. (BTW, the WD label says for surveillance use. Curious to know how this makes it different from regular WD hdds.)
