Pros: I took a quick Blackmagic Disk Speed Test and the R/W transfer rates were faster than specs -- 190/90 (in OS X 10.8.5). I don't know what happens to flash speed over time. It's a bit slower in Windows 8.1, 180/80. Okay, okay, if you spend a whole lot more money, there are faster drives.

Cons: Bulky, large, which I suspected would be the case before I purchased, but I liked the graphic design. It does not fit in the first USB slot under an Ethernet port. The drive is too wide, thick. But I have gobs of USB 3.0 ports, top and back, so clearance will not be a problem.

Other Thoughts: The 64GB capacity is about right for me. I always worry I'll need more room than I have, although my 32GB flash drives have very little on them.

Pros: Crucial Ballistix Tactical 8GB Low Profile BLT8G3D1608ET3LX0

Bought a couple singles, not a 16GB kit. There's never a problem running singles. These are specified as 1,600MHz 8-8-8-24 @ 1.35V, so it was a no-brainer to run them 7-7-7-24 @ 1.5V -- on Shell Shocker for a great discount. Too! Note: the 1.35V spec is a dead give away that they'd run faster.

Opened my case, opened the new memory, took out the old 2-stick 8GB, put in the new, booted into BIOS, set memory to the second of two XMP profiles to get the 1.5V setting, changed the timing (only those shown above), rebooted, ran Windows 8 memtest with no errors, ran WEI to no avail since the results were the same 8.1 as before. So now I'll hold my breath for at least a month before I'm confident in this new RAM.

The yellow isn't too prominent because they are so short, but what I can see goes quite well with some of the yellow power wires. Sort of ties everything together. It all looks great with my purple cold cathode light.

Pressing the memory into the slots worried me, but the heatsinks took the pressure and they felt nobly robust.

Low profile. Where have these been all my life? I've needed them forever. For my last three systems I have needed low profile. Except I don't need 32GB, four sticks, and my ASRock Z87 Extreme6 motherboard wants two sticks in the outside slot pair, therefore there is no heatsink clearance problem out there anyway. But I don't care. My first low profile DIMM and I love them. Actually, I don't need 16GB, either. I just wanted to see if they would run 7-7-7-24. I knew they would. Maybe it helps that I worked for a memory manufacturer who's initials are I.

Cons: none

Other Thoughts: I'll let you know if there are any problems that come up later.

For this new build I got a Haswell i7-4770K.
