Pros: Inexpensive and fast

Cons: None yet

Overall Review: I bought two of these to use as backup drives. I have filled both of them to capacity about 12 times so far. No complaints. Speed is great, I worry a little about heat in an essentially sealed plastic (insulating) housing.

Pros: Small, cool. Works pretty well, except for when it doesn't

Cons: It is slow - I hoped to replace a power hog Xbox 360 slim with this. It worked well for a while, but was very sensitive to network conditions. I have gigabit ethernet running from the media center PC to a Cisco Gbe switch, the Ceton wire directly connected works great, if I add in another switch inline, it doesn't work reliably. Not an issue for the other HTPC's that stream from that same media center host. Recently it has been rebooting itself during the first 10-15 minutes of operation. I never could get the Ceton add-in loaded on the media center host.

Overall Review: I finally pulled the Echo out and put the Xbox back in place... It is a really cool idea, and I will hold onto it hoping for a firmware update. It's so close.

Pros: Very fast for a rotating drive, high throughput and fast seeks. Error recovery supposedly can be disabled, so it should work in RAID arrays. I'll try soon enough.

Cons: None so far

Overall Review: I have had very good luck with Hitachi drives, I used to have good luck with Seagate, but I have replaced so many of them in the last couple years that I will not be using them any longer. WD Black and enterprise drives are great, but too expensive. I hope these work as well as the Hitachi drives of the last 10 years.

Pros: This one worked for 349 days!

Cons: Then it died

Overall Review: Luckily we have a reasonably current backup. No more seagate consumer level drives for important customer PCs. I used to be a Seagate fan, but I have been RMAing these things for about a year now, and I am scared to use the replacements.

Pros: It's a WD Black drive - they have been at or near the pinnacle of performance for rotating drives within their class. I was worried, reading many online reviews that the access time may be slow, but using the same test software I am getting consistent ~12msec seeks including latency. Lots of reviews show 15+

Cons: Throughput for this old beast is not quite up to par with other drives today, but for my workloads, access time is more important than throughput. Still a hot drive.

Overall Review: The new model just came out with higher throughput, and apparently optimized seeks. That makes this drive suddenly cost competitive with other drives that do not have 5 year warranties and do not have the low seek time. For the time being, this will replace Hitachi as the go to 7,200 rpm 4tb drive for me.

Pros: Low Profile, small footprint. Same width as network racks Look good, price is right. You can actually fit 2 3.5 inch, 1 2.5 inch drives and an optical drive all at the same time.

Cons: Tight assembly takes some planning. Some motherboards don't play well with connector locations. Power supply depth is a major concern.

Overall Review: I have 4 of these cases in use right now. One has 2x4tb drives a 128gb OS drive and an Antec SATA hot swap tray - used as an HTPC and media server w/ i5-760 and AMD HD6670. One has an i7-4770, Intel quad GBe NIC, 2 Velociraptor 500gb drives, a C300 128gb boot drive and a WD320BEKTdrive. One has an i7-3770 and a couple drives running Windows Server 2008 and Exchange 2013. They are all silent and stay cool. As mentioned above, they are the same width as regular rack mount gear, so I have a couple of them sitting in a network rack with the other network gear.
