Product as advertised. All is OK. Satisfied.
This is just an initial feedback. SSD came well packed. Like it is the rounded corner version. Very lightweight and compact as expected. Have to test it in a USB 3.1 high speed enclosure yet to see about the write and read speed and also how much capacity is available under Windows 10 and Mac OS.
My initial review was positive. But the real life testing shows some serious concern about this 4TB SSD. On Windows 10 there is 3.63TB available. Formatted exFAT or NTFS, same capacity. On MAC OS system real write speed on high quality enclosure is just 370-390MB/s, read speeds about 360-370MB/s on exFAT. That's acceptable, but not great. If formatted as NTFS, write goes nearly up to 450MB/s, but read speed drops to 320MB/s. Here comes the worst part though: when testing the overall health status on DRIVEDX software, an immediate warning on FAILING indicator regards the life span of the SSD comes up. This effectively means this drive can fail anytime. Every time a new write of data is executed on this SSD, the number of raw value of the fail count rises! I do not recommend this SSD whatsoever. I repeat, do not buy this drive, if you care for your precious data. As a backup of not important stuff, maybe it's OK. But not for critical work. Shame on the manufacturer
