5 out of 5 eggsSo far, so good

This review is from: Seagate Constellation ES.3 ST4000NM0023 4TB 7200 RPM 128MB Cache SAS 6Gb/s 3.5" Enterprise Internal Hard Drive Bare Drive

Pros: 16 of these in production at present in a large file storage cluster. So far they've performed well.

Cons: None so far.

Other Thoughts: This probably goes without saying, but as drives get bigger, it's really important that you engineer your solution for not only enough raw space but also enough IOPs.

5 out of 5 eggsGreat SAS drive!!

This review is from: Seagate Constellation ES.3 ST4000NM0023 4TB 7200 RPM 128MB Cache SAS 6Gb/s 3.5" Enterprise Internal Hard Drive Bare Drive

Pros: Drive came in a nice clear plastic case and wrapped in Bubble wrap.

The 4TB size is superb for an enterprise drive. Physically the drive looks like a standard 3.5” black and metal Seagate drive (but still nice!) The Formatted size with a single NTFS Partition was 3.63TB space available!
This drive has SAS Performance and quality with energy efficiency + 6GBps!

Here are some bench results:

Using AS SSD (it was one I had available)
Seq Read: 172.87 \ Seq Write: 170.85 (MBps)
4K Read: .80 \ 4K Write: 2.05
Acct Read Time: 11.927ms \ Acct Write Time: 1.877ms

Using Crystal Mark3 @ 1000MB
Sequential Read: 181.9 \ Sequential Write: 178.8

Cons: SAS drive so you are limited to a SAS controller with the correct pin setup to connect the drive – you cannot connect this to a SATA controller.

The temperature of the drive seemed to be a little hotter than SATA drives, but for systems that would use this type of drive as sufficient air cooling is necessary anyways, this isn't a major deal. The difference may have only been 2-5 degrees but I don’t have a Infrared Thermometer to accurately read the temps so was just an observation from touch.

Other Thoughts: This was installed in a WHS 2011 Server.

I used this drive with an SAS controller (LSi PCIe 2 x4 card (SAS9211-4i). The cables I had were only for a SATA drive, so I did have to order another cable (Mini SAS to SAS). I thought I had one, but was wrong)

You’ll have to make sure that your SAS controller card supports the 6.0 Gbs speed, has a SAS cable, and that it supports a 4TB hdd.

I was unable to put the drive into a raid to test raid performance due to only having a single drive in this size / format. However I’m sure the performance in a raid setup would be quite nice!

To help with speed references, My Server Hardware is an ASROCK AM3+ motherboard with a Phenom II 965BE processor, 8GB DDR3 memory with multiple HDD’s. This was installed as an additional drive with server storage. (not used for primary OS)

The speed of this drive does not match up to the performance of an SSD (as most would expect), however in comparison to other mechanical hhd’s with the size and performance for money.. this is still a great performing drive, and still only a 7600 RPM!!

Overall, if you have a need for a drive like this for your system, Order one!

5 out of 5 eggsExcellent Hard Drive, Solid.

This review is from: Seagate Constellation ES.3 ST4000NM0023 4TB 7200 RPM 128MB Cache SAS 6Gb/s 3.5" Enterprise Internal Hard Drive Bare Drive

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.

5 out of 5 eggsGreat drive.

This review is from: Seagate Constellation ES.3 ST4000NM0023 4TB 7200 RPM 128MB Cache SAS 6Gb/s 3.5" Enterprise Internal Hard Drive Bare Drive

Pros: I am using this as my primary genomic dataset decompression/analysis/recompression drive. It replaced the competitor’s highest-end consumer-grade performance hard drive, which also has a five year warranty. Sustained writes of 170MB/s are amongst the highest I’ve seen from a single (mechanical/platter-based) hard drive. For comparison, the drive it replaced topped out at 150MB/s according to my testing. This Seagate drive also has slightly lower latencies than the drive it replaced. At idle it pulls a few watts less than the drive it replaced. Finally, it is noticeably quieter (though in an enterprise setting this is irrelevant).

Cons: It runs a few degrees warmer than its predecessor (it’s in the same spot in the same case so I am confident in that assessment). The system also pulls 2-3 watts more under sustained use as measured from the wall controlling for the addition of the SAS controller card I installed.

Other Thoughts: Moving from a high-end consumer drive to this enterprise drive yielded minor performance increases given my usage scenario; I am most pleased that it is quieter than the drive it replaced though as alluded to most purchasers likely will not put this in an mATX case that’s sitting on a workstation desk. Of course, I unfortunately can’t yet comment on one important aspect of a hard drive, reliability.
