    I'm talking about the BB deal case. and yeah my clips are on the back side as well.
    I dont have my case near by so i am improvising on the image.

    The red area on the pic both top and bottom is where i started with the flat head screwdriver, i get a little started then put the flat automotive pry tool in and leave it there, then i start the other side using the same process. Once both are in there just gently push on pry tool to wide the size of the gap, do i on both sides evenly then the tabs in the back will unclip "pop" out, then its just sliding the unit out in the direction of the blue arrows.

    Again that is what worked for me, and i got two perfect cases that way. I didnt try it with a card the first time so that is why i didnt try going in from the back side where the usb is with these sets.

    Got the four 8TB drives I ordered yesterday, no problems getting the drives out with the clips intact thanks to all the info in this thread! Only bummer was that two drives are from China, two from Thailand. Are the reliability issues with the China made drives something that's been documented/tested somewhere?

    Got the drives undergoing testing as we speak...

    A quick bench of Four WD 8Tb Reds in Raid 5 on an LSI 9270-8i.
    Quite impressive for platter drives.

    No idea. I had seven 3 tb drives in this rig before manf. in 2011 that were nowhere near this quick. Individually each 8tb drive was showing about 180-200.

    180-200 is what I have seen from other reviews on a single disk. When you pack 8tb onto a disk that is a lot of bits moving under the read/write heads on every rotation. The higher the data density the higher the sequential speeds are. Move to random read/writes that density doesn't help as much.

    I could see 600-700 in those benches since a 1 out of 4 drives is used for parity. But 900+ was really unexpected. I do have all the write back functions and write back policy enabled. No cachecade or bbu installed.

    Yeah that's some really impressive write performance that made me think it was all cached result.
    According to Understanding RAID Performance at Various Levels - StorageCraft, the write performance of RAID 5 is NX/4. So (4 x 200 ) / 4 = 200.
    So i'm very surprised you were able to achieve this level of performance. Hmm, how is this possible without cache?

    EDIT: is this the controller Amazon.com: LSI LOGIC MegaRAID SAS 9270-8i Storage Controller LSI00326: Computers & Accessories?
    It seems to have 1GB DDRIII cache (1333 MHz) cache. Are you sure it's not playing in here?

    The deal is back again. Don't know how long it's going to last.

    Look's like just on the 8TB drives, unless I'm missing something on the 4TB.

    How are you guys ordering more than 3 at a time? I am clearly missing something.
