these are consumer SSDs
so what
Even the "PRO" is consumer and a 2TB is priced about 800 USD
in doubt - so what too - nothing you buy every day and in case of a
RAID10 i put out the drives holding the OS and data and move them to the
next machine, change the MAC of the internal NIC in the config and i am
done (the other network cards and the wireless card are move too)
Look at one of Intel DC SSD, the S3610 1.6TB is about 1500 USD. Twice
the price, 40% less capacity
and do you really need them?
for what usecase?
performance?
well, the RAID10 versus RAID1 with two nearly double priced achieves the
same or at least nothing different you could notice in real world usage
and if one dies that's what RAID is for (the I is for inexpensive) and a
few years later you get a "consumer SSD" with the same size probably
much cheaper while a ton of tests prove that the consumer SSD's suck a
lot of writes over a long time too
