Pros: -Reliable memory at rated speed -Arguable great value -Oversized heatsink presumably assists heat dissipation, larger compared to competing RAM solutions at similar price point

Cons: -Nothing

Overall Review: This only reason I am leaving a review 4 years after the fact is because I came back to buy another two sticks to fully populate the FM2-based AMD A10-6800K MSI system I built for them in 2013. It is their primary system and I used two of these sticks of RAM running at the rated 1600 speed and the system has been running solidly as the day I bought it. My parents use their desktop system for very light duty use including web surfing, word processing, and lots of YouTube video watching. Overall I'm very pleased with this RAM, it did it's job and has produced no errors. I just ran a memtest86 and the RAM tests perfectly, so I'll be purchasing another two chips to bring the total system spec up to 32GB. Admittedly, another thing that spawned my review was the surprisingly number of folks rating this at 2 stars claiming that it brought nothing but instability to their systems. As a system integrator/PC builder with over 20 years of experience, I feel I know what I'm doing and this RAM worked just fine.

Pros: -One of the only MATX X570 options -Pretty, good price

Cons: -Major issues posting -Quality Control issues -Compatibility issues

Overall Review: It pains me to leave a 1-star review on this product because I really wanted to like it. I have 7 other X570 boards (ASUS Dark Hero X570 x4, GIGABYTE X570 Master x1, ASUS X570-I Strix Gaming mini-ITX x2), and all of them work perfectly fine, post with no issues with the G SKILL DDR4 3600 RAM and CPUs. Then there's this Asrock X570M Pro4, and it had major issues. I purchased this in early November 2021, it came with the 3.10 BIOS, rendering it non-compatible with the 5600G I wanted to pair with it. No problem, I installed a 3400G, it posted, and I upgraded the UEFI to 3.60, it posted successfully at that, so I gracefully shut down, installed the 5600G, exact same RAM (at 2100 speed) and it would not post. CPU, VGA and BOOT lights stay lit, DRAM not lit at all. DRAM was fully seated and I tried it in various slots, including the recommended slots that the manufacturer has in the manual (A2 and B2), tried single RAM stick in A2 as well to no avail. Apparently, a lot of people have issues with this board not posting and the DRAM light not lighting during post. Some experience endless boot loops. For me, having experienced numerous other X570 motherboards that work flawlessly out of the box, I don't have the time or patience to deal with this poor offering with low compatibility and/or quality control issues. So it's getting returned for a full refund. Another user even RMA'd the board, received a 1:1 replacement and the replacement board had the exact same problems. If this is your only motherboard, avoid it. If you intend on putting a 5600G or any new Ryzen 5000-series in it, you may get it only with the 3.10 BIOS, rendering it non-postable unless you have an older Ryzen to install temporarily to flash, then it still may not boot. I owned two other Asrock motherboards in the past, and never had any issues with them. This was a bad experience. Maybe I wasn't doing something right, or maybe the board genuinely had issues. I don't know, but I don't have the time to mess with it any longer.

Pros: Quiet operation Fast operation Customer service Extreme reliability

Cons: Device is stamped as a 2000GB capacity and not a true 2TB which would be 2048GB.

Overall Review: I've been using four of these drives in a Buffalo LS441de 4-drive RAID 5 array Network Attached Storage (NAS) unit that runs 24/7 in a residential setting. The drives run quietly and perform fast and can deliver data to network users very fast. I was previously using one of these drives in a Nexstar 3 external USB 3.0 enclosure as a backup drive. I have never experienced any faults or errors with these drives and they perform fast, quietly, and without any issues at all. In the long past, I've had very positive dealings with Seagate customer service and have been impressed by their quick action taken on any issues I've encountered. Additionally, if you do ever have any data corruption or loss, Seagate's Seatools and rescue software is available freely and only functions on Seagate devices. Both software applications have saved me on several occasions. I now ONLY use Seagate for all of my hard drive needs.
