Sharing is caring.I almost jumped on this train, but then I remembered that we'd be decommissioning soon enough Netapp with dozen of PM1633 3.84TB SAS12 drives (7K TBW).

I'm not very good at translating LBA to terabytes, but it looks like the drives have had 5 years of power on time, only terabytes written, and like 31 power cycles. 100% reserved space. So they are probably fine.Two toshiba drives smart data:
Thoughts?
I think people, or at least me, get excited about the idea of giant piles of storage just... escaping into the wild at once.I don't understand why so many folks got overexcited about me mentioning these drives.
There are websites that will do the conversion for you. Each LBA is 512 bytes.I'm not very good at translating LBA to terabytes, but it looks like the drives have had 5 years of power on time, only terabytes written, and like 31 power cycles. 100% reserved space. So they are probably fine.

A lot of us here at the STH Great Deals Forum will always jump at the opportunity to purchase fast reliable storage at big discounts.I don't understand why so many folks got overexcited about me mentioning these drives.
a) As I said soon, which translated to my company language, means several months, not days. It may not even happen until next year.
b) You don't have to guess too hard what I do for a living, so, of course, I looked up prices of LSI 3k series SAS HBA controllers (around $100-150), which seems like a cheap way to go potentially run these drives in my pc.
c) I am not the only engineer aware of these drives' existence, and my colleague gets his cut before any of the STH crowd does. Sorry, c'est la vie.
d) I'm not even 100% sure if the NetApp SSDs are PM 1633s or something else entirely.
I can't put the cat back in the bag, but please understand that my post was mainly for my reasons for not jumping on this deal. That is all.
15% life leftI think mine was delivered today. Will give it a spin later.
Mine was 9% for 4 drives and 7000 bad sectors.15% life left

It's strange that 'Average block erase count' equals to the 'life remaining' in this software. What does 'Micron storage executive' reads about these drives?just received the drives and here are the details.
Has anyone cracked one open to see if the PCB is full or half sized?
Nice! Yeah the two I purchased perform really well. Very pleased.Thanks all for this thread, I went with the THNSN81Q92CSE, its currently going for $62 and with the endurance its a safer bet than the Micron 1100 [$50] as well as better IO performance than a lot of these cheap new ones (PNY CS900 2TB[$62] or TeamGroup AX2 2tb[$66])
shwifty five ;-)Ugh, I really don't need more SSDs right now... How many should I buy?
