Pros:Easy to use web based management softwareSupports sata tooSupports larger capacity hard drivesAlert you when a drive is failing and the management software tells you which drive is failing where it’s connected (the alert states it based on the corresponding connected connection and the fact my cables are labeled and my drives are also labeled doesn’t hurt either) it automatically rebuilds raid 1 arraysYou can mute the really loud shrill noise it makes when you have a failing driveIt’s not too slow (then again I had a raid controller that was pretty old and slow and was a pcie 2.0 pulled from a retired r710 server after i upgraded the r710 so really anything was better than that Dino)Drivers support windows 11Easy and painless to install and usePhysically durable and well built. Doesn’t feel cheapSupports multiple large capacity drives on multiple arraysCompatible with multiple operating systems including windows 10 and 11. Definitely has windows 11 compatibility. This includes drivers.Functions well hasn’t crashed or froze up my computerIt costs less than $200 for me it was about $150 plus taxWell packed.Drivers are easy to find on the manufacturer website.Works in desktop PCsIncludes low profile bracket if you need oneIs a true one slot card not a 1.5 slot with tall heatsinkIt’s pcie 3.0 not some stupid halfarsed pcie 2.1 or something olderDoesn’t overheat and thermal shutdown or BSOD due to overheatingGood for 24/7 use (so far) so it’s good for home labs and NAS RAID setups that are used as primary centralized data and application software.You can run and access multiple arrays at once with minimal slowdownAnd best of all it absolutely totally DOES NOT SUCK!!!!!Definitely worth picking up especially if you’re a Windows 11 centralized data and application server userThere’s also a similar controller by the same manufacturer here on Amazon for $100 if the extra $50 plus tax scared you off. If so I recommend that one as well it also supports windows 11 and 16 sata drives across the same type of cables and is also a 4 port card. So keep that one in mind too if you want.These are great controllers with great compatibility and easy to install and easy to use so DEFINITELY pick one up!Cons:Doesn’t include cables but you can get some cheap third party ones here on Amazon. I got a 2 pack of relabeled mini sas to sata ones for less than $30 including tax on Amazon. This controller supports 4 cables and 16 drives totalIt states it supports Linux but I’m a Windows user not a Linux user (I can’t Linux even if my life depended on it) so I can’t really speak on that myselfNo support for Mac according to what I seeSorry rich 1% people and major conglomerates who are so filthy rich they can afford a Mac without using their mortgage money entire life savings work five 9 to 5 jobs not eat for a year and go into massive debt to afford a Mac like everyone else in Main Street America would have to do to afford a Mac. This is not the card for you!

I'm using RAID-5 on a custom Windows 10 pc for a home media server used both as a LAN server for home streaming and as a Plex server so friends can stream my collection remotely. I originally started out using Windows 10 software RAID for a couple drives, but that was terrible and I quickly outgrew it, upgrading to a HighPoint RocketRaid 640L which worked great but maxed out at 4 HDDs. Since I run 4tb drives, this meant it topped out at 12tb in RAID-5 which I once again outgrew. I figured out that it was going to be a lot more expensive and a much bigger pain to replace all the drives with bigger ones than to just get a different RAID controller that could hold more drives, plus staying with 4tb drives is cheaper each time I need a little more storage space.So that's where this RocketRaid 2840C comes in. It can hold up to 16 drives via two of their SAS to SAS or SATA breakout cables (don't get the cheap 3rd party ones, suck it up and overpay for the HighPoint ones). For my purposes with the 4tb drives, that mean's I'll have up to 60tb in RAID-5 which should last a good long while even with a 4k UHD bluray collecting habit lol! This card and the HighPoint online RAID management also supports running multiple controllers withing the same RocketRaid family, so I have no concerns about running out of storage space (at that point, the bigger problem will be the physical space the HDDs would take up lol). As an additional note, hardware-wise the controller card doesn't draw huge amounts of power from the PSU, it's low-profile, and has heat sinks.I really can't say enough good for the HighPoint online RAID management, this is an absolutely brilliant solution for users like me. The interface may be clunky, but there are clear walkthroughs available for how to use it and the online management makes maintenance, adding storage space, and changing controllers just sooo easy--and you do not need to be a computer wizard to use it. If you posses some basic to intermediate knowledge of computers and the ability to know what to google to do your research in setting up the right RAID array for your needs, you can use this brand's controllers no problem. When I upgraded from the 640L to the 2840C, I was staggered at how smoothly it went. It literally involved pulling the old card out of my pc, installing the new card, running the new SAS to SATA breakout cables to my drives, booting back up, installing the driver for the 2840C, and my entire RAID array was just...back. Like nothing ever changed. No new configurations, no problems, no bs. At the same time I also added a new drive to expand my total array storage capacity by another 4tb; this is very easy too, you install your new drive to your case, run the cable, initialize it in Windows and then go through the couple of steps to run Online Capacity Expansion in the online HighPoint management. This will rebuild the array with the space of the new drive added, which takes a while (doing 16tb with 5 drives took about 34 hours for me, but the array was accessible during that time--the wait is just for the additional capacity). I haven't had a need to change RAID levels, but I understand that it's similarly doable with the online management.This is just suuuuper smooth and simple and maximized the uptime of your array. I'm giving the old chef's kiss to this entire setup and I'm totally sold on the RocketRaid products with online management concept, it's absolutely brilliant and a great choice for the many of us who are increasingly getting fed up with fickle, greedy streaming services and/or are digitizing our hard copy collections for centralized home or remote streaming and finding the all-in-one box NAS setups too limiting. If you possess the ability to set up something like that, you can certainly use these controllers with a basic, familiar pc and have something way more flexible and upgradable. Highly recommended!

I have 5-4TB drives connected in RAID5 using SAS to SATA Cables. Has been running for several months with no issue at all. Performance is great for a mass storage device, no issues playing 4K movies from it. Setup was painless.

元々RocketRaid2300で4台のHDDにてRAID5で運用していたのですが、2300はPCIeが1レーン、HDDも3Gps対応と、HDDのパフォーマンスを生かせないのと、容量に不足が出てきそうだったのでこちらにリプレイスしました。環境：Mother:Asrock H61M-ITXCPU: Intel Core i3-2120T 2.60GHz定格Memory:4GBSystem SSD:Intel 520 60GBDATA HDD :Seagate ST3000DM001 ３TB×4 RAID5にて運用。使用可能容量９TBOS：WindowsHomeServer2011にて、特にトラブルなく運用できています。RocketRaidはハードとソフトのハイブリッドRAIDですが、特に転送速度も問題なく（下記データ参照）HDD本来の転送速度の3倍近く出ています。今回は2300に繋げていたHDDをそっくりつなぎかえたので、そのまま認識してくれました。前回の2300は時々SATAケーブルの認識不良が起きましたが、今回は評価の高いファンアウトケーブルを同時購入して接続したためか、使用後全くエラーが出ていません。11月頭に購入したので、BIOSは最新の1.5でした。スリープが使えないのが難点ですが、他の方のレビューでサスペンドは使えるようなので、試してみます。---------------------------------------------------------------------CrystalDiskMark 3.0.1 x64 (C) 2007-2010 hiyohiyo Crystal Dew World : http://crystalmark.info/-----------------------------------------------------------------------* MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 434.445 MB/s Sequential Write : 432.581 MB/s Random Read 512KB : 53.853 MB/s Random Write 512KB : 37.241 MB/s Random Read 4KB (QD=1) : 0.819 MB/s [ 200.0 IOPS] Random Write 4KB (QD=1) : 0.394 MB/s [ 96.1 IOPS] Random Read 4KB (QD=32) : 5.689 MB/s [ 1388.9 IOPS] Random Write 4KB (QD=32) : 0.534 MB/s [ 130.3 IOPS] Test : 500 MB [F: 74.8% (6270.4/8383.2 GB)] (x2) Date : 2014/12/23 5:36:52 OS : Windows Server 2008 R2 SP1 [6.1 Build 7601] (x64)

最初のものは動作が安定しなかったので交換しました。特定のPHYでエラーが多発しました。V1.0のものは非インテルマシンでも正常でしたが、今回買ったV2.1は非インテルマシンでHGSTのドライブを正常に使えません。BIOSが関係しているように思えます。V2.1では背面のNVRAMや電源周りのICが無くなっています。スペック的にPCIe gen2 なので高速SSDx8では性能を発揮できません。2枚使って分散させるのも手でしょう。ディスクフェイル時のブザーの停止方法が不明でした。純正のソフトウェアRAIDの機能は評価していません。LinuxのMD RAIDで評価しました。あと、ケーブルが付いてくる物の箱のパッケージが表示されていますが、この製品にはケーブルが付いてきません。ケーブルが付いてくるのはRocketRAID 2722LFなのでしょうか？ケーブル付きなら安くていいのですが。。。

Unfortunately having purchased 3 of these cards found to my dismay that only one functioned correctlySo retuned item unopened to save all the headaches trying. To set it up

I bought this instead of an all in one NAS solution.I had a spare box and had to purchase the drives anyways, So I thought I would take a crack as using this.I LOVE THIS CARD.Super Price point.Great performance.Raid 5 solution to protect our families data.Did I say how awesome the price was.Look for my review on the cables that go with this.Get a Life time warranty with Star tech and not a cheaper brand.Great card.Good forums for information.
