Something I haven't seen emphasized enough with this move is that by obfuscating a drive's vendor and manufacture date, you won't know if your drives are from the same batch. This is important because if there's any manufacturing defects in a given batch of drives, the failures are likely to happen around the same time, greatly increasing the chance of losing data.
Basically, Synology drives are not only more expensive, they're also statistically speaking less reliable when building a RAID with them, negating the very purpose of the product. What a dumb move.
