Slightly cheaper than Samsung 860 EVO 4TB but i see almost no reason to buy this SSD as you could get the mentioned SSD at couple of tens more but unless if you had a very tight budget to buy 4TB SSD. May or may be not worth it depending on pricing of this SSD and 860 EVO 4TB and pricing delta as both of them had nearly identical performance aside from HDD-like R/W when this SSD runs out of cache while transferring huge files. [Dec '19 ColdSpy]
