arghhhhh must resist.. I want a 4tb..


Please SSD Gods.. give us a $100 4tb drive..
Updated on 7/21: The actual TBW rating of the 2TB PNY drive is higher than I thought - calculations updated to reflect this.

I purchased 2 of them a month ago and installed them into my 4-bay QNAP NAS as the system drive. They are configured as RAID1. I ran several tests by doing a drag-and-drop of a 1.13GB file between a windows 11 laptop and the NAS. I ran the tests in both directions. The copy speed was consistently 1 gbit/second, which means it was constrained by the gigabit network speed.

Update: I just reran the test with a larger file -- 2 gigabytes. Same results -- the copy speed was consistently 1 gbit/second, which means it was constrained by the gigabit network speed.

I just installed a 3rd one to the by recording drive for the 4 IP cameras I have on the outside of the house.

For those concerned about wearing the drive out from all the writes from the cameras: My cameras average a write load of about 192GB/week. Per PNY the TBW rating of the 2TB drive is 540TBs, so the drive should last about 54 years. ((540*1000)/192*7/365)

Of course, many of those bytes written may require multiple writes, but I think it's a safe bet I'll get 6-years of use out of the drive, which is an average annual cost of $10/year.

TLC drive, no DRAM. From what i found the TBW is 450

Would have bit for my unraid cache drive upgrade, but a friend just gave me a 1tb ssd as a thank you for upgrading their computer and doing a few other things for them. It's hard to beat free.

This drives speed drops from 400+ mb/s to 20mb/s after it transfers 100gb, according to a review. Bought one anyways

That's good to know. I've been eyeing these as cheap NAS storage, I'm assuming the drop in speed occurs once 100gb has transferred in a single job and then resets once you start another transfer?

Yup, they said after about 20 seconds a new transfer started at full speed. Definitely not an os drive, but seems like a good storage drive

The copy file speed is limited at 100MB in 1gb network. If you can get 1gb coping speed, your network must be 10gb.

He said 1 gigabits. So he is right. Of course factoring protocol overheads.
