This review is from: CORSAIR Hydro Series H100i Extreme Performance Water/Liquid CPU Cooler. 240mm
Pros: Looks nice.
Worked well for a short while, until it sprayed a leak.
Had software for it but we didn't get far enough into testing to be able to use it before the failure.
(Less than 2 months)
Cons: Expensive. Low quality, and a good reason to stick with Koolance products. Danger to your system when it leaks, not if.. A real pain to clean up if you are lucky enough to catch it.
I'd be shipping it back to Corsair for a refund if it weren't for the rebate,which I am SILL waiting on, should have known better.
Corsair should stick to what they do best, and it isn't making water cooling solutions.
Other Thoughts: We'll see how things go when a new solution arrives.
Corsair may be looking at 64GB replacement ram, I7 6 core and the usual $300-400 motherboard.
First came a hissing sound, next thing I'm going is scrambling for the power cord. the connection at CPU water block just sprayed all over the motherboard CPU and ram.
All in all for us, this rates at an Epic FAIL.for equipment.
Pros: Newegg product listing N82E16822178306, Seagate Constellation ES.3 ST4000NM0023 boasts as solid drive.
I haven't visited Seagate's High-end product line since their departure from the 5-year warranty of standard consumer lines several years back and only have had two 1 TB models recently for video editing / capture ( RAID 0).
Since some time has passed from owning a high-end Seagate product, I welcomed the opportunity to see what Seagate has been putting under the hood lately on their Pro line of hardware, especially one in the price range near a half grand. Even with a high price there are just some inherent advantages that SAS offers over SATA and I occasionally prefer offloading to a SAS CPU than having local system boards handling data so seeing what SAS2 is in comparison to consumer lines and SATA will be interesting. (Wiki offers a good starting place for the casual beginner when looking at SAS vs SATA and determining if one or the other is a good choice for and particular utilization if you are new to SAS).
With Seagate's Pro lines, I'm seeing a toe-to-toe stance when dealing with their competition and perhaps even a little extra toe stomping when it comes to exceeding longevity and outliving the problems their competitors have on their Pro lines.
The drive is smooth, well put together and operating quietly and surprisingly cool, when compared to other Seagate drives and competing brands. If you see the notes in the "Other Thoughts" section, you should notice that this SAS2 drive falls in line with pretty much the performance of SATA III 6.0 drives. Keep in mind that SAS offers drive controller intelligence that SATA does not; also, SAS has the ability to monitor backplanes via sideband cable options on most mid to high level SAS cards. SATA more often mimics monitoring via software solutions weighing the system down more so than SAS hardware solutions.
Another big factor that stands out is the little amount of heat that this drive puts off. True, I'm not running SQL Server or Oracle DB on the drive, but given the fact that I am moving a 40GB chunk of data all over the drive for an hour, and it's doesn't really get warm, helps draw the conclusion that Seagate's enterprise class drives run cooler and can take on more tedious encounters on a 24/7/365 basis.
Further, not a single sector showed any defect, skip or error after a pounding 24 hour testing session
Cons: With me, the only major and prohibitive hurdle Seagate has thrown me for Pro line models is the price for owning their products SATA or SAS models. In order to get a 5-year warranty, there is a considerable price point difference. With lesser warranty as compared to their competitors for consumer lines, I choose to look at warranty length, reviews / failure rate, customer service and price when buying into a product line for use in my equipment. With consumer lines you'll see a shortfall but no so with the Pro line models. Other than the above, I am not seeming much of any cons physically with the drive or performance.
Still, I honestly have to admit, though impressive performance, at it's current price point it's not something that I'd personally jump at first sight, so do some research to make sure this is designed for YOUR specific needs; otherwise, a good SATA III 6.0 will offer close to the same performance. I might be tempted to burn through a handfull of cheaper drives in a 1 or 5 RAID array at a cheaper price and still be able to have a few spares on hand. With 3 and 5-year warranties for consumer line from Seagate and other competitors, some TCO (Total Cost of Ownership) and performance/failure probability calculations may be in order to see what points work best for any given scenario.
Other Thoughts: Some important considerations for those getting into the SAS arena and Enterprise drives are as follows.
Be aware that /w Seagate Constellation ES.3 ST4000NM0023 & many other SAS drives, you will need either a back plane or cable with supporting connection of SFF-8482 (SAS 29 PIN) and not standard SATA; though they look very similar, you won't be able to plug your data or power cables into the SAS drives as you would on SATA drives. StarTech offers cable solution part SAS808782P50 / UPC 65030848039 /w life time warranty that workes on SAS. SEE NE listing N82E16812400142, if needed.
In my case, it was just a simple task of opening the side panel on rack, opening server chassis and unplugging my (Mini SAS) SFF-8087->SATA cables, swapping to SFF-8087->(29 pin SAS)SFF-8482 x4 cables and plugging the power into the Y pig tails. The particular SAS card used to drive my SAS array and SATA is a Highpoint RocketRAID 2720. Initially the BIOS didn't support over 2TB and the Seagate showed up as 2TB; flashed SAS controller to BIOS V1.5 and had no issues after that; it was a 3-second Flash fix, and everything went beautifully without issue and the drive just worked after that. Both, the HighPoint RocketRAID 2720 and the Seagate drive, worked well hand in hand.

Pros: The size of the drive is a nice offering for archives and backups. The drive runs cool and very quiet. The drive responds well to hot-swapping on SATA as well as SAS interfaces
Cons: Over time I have noticed this dive growing slower and slower to the point that it seems that backups stand still.
I am not running this drive as part of a RAID set but as a standalone drive on a raid connection. While other WD Blue and Blacks show their full speeds this drive for some reason is reading 1.5. The drive is in it's native format as shipped and has no jumpers installed so it should be operating and registering at full speed. I've since moved it to a SAS connection and and have seen slight increase of transfer rate but nowhere near SATA II or III rates. The slowdown and halts are intermittent still with this drive. The drive still registers in BIOS as well as disk Management in Win 7 64 bit as well as AMD RAID and Promise RAID monitoring but is still reading as 1.5 , SATA I. Odd at best but still functional albeit inexplicably slow and has been faster in the past when tested.
Other Thoughts: Continuing to monitor and review this product to determine why there seems to be a performance hits even with latest SATA/SAS controller software and Drivers while configured as a straight non RAID standalone drive.READ FULL REVIEW
