Shr2 vs raid 10 l also have a offsite USB drive, just to make sure. DSM I purchased a Synology DS220+. If Synology had hardware raid it wouldn’t be able to do data checksumming and recovery because of the interaction with btrfs checksumming and data recovery using raid parity. you cant get both. However, now that I have read more, it seems that using RAID 6 on a home 4 bay NAS (which doesn't need to be up 24/7 like a business might), RAID 5 may be better choice for performance and space. Vorteile von RAID • Breitere Einsatzmöglichkeiten. I prefer the bottleneck to be the network rather Verwandter Beitrag: RAID 5 VS RAID 6 über Vorteile, Leistung und Anwendung. It's ONLY if you have one drive larger than all the rest that you lose any space, and it's this that gives SHR the biggest advantage over regular RAID. Is Synology a good option for your needs? Seems so to me. I initially setup the NAS with one Note: RAID 10 vs RAID 6. I may expand the 5th bay with 8tb or 16tb later if space runs out. Co je to SHR?

It offers high read/write performance and fault tolerance. SHR and regular RAID options work exactly the same way, but the difference is that you can mix a different size drives on the Synology RAID. I have 4 x brand new identical 16tb Toshiba HDDs and I have the Synology 10gbE network card installed. RAID F1 Implements block-level striping with Use SHR for 4 HDDs in the Synology. With those same 4 drives configured with SHR2, you will have roughly 36TB of usable storage, and 2 drive redundancy. Bücher und Hardware zum Thema gibt es bei Amazon: RAID-SHR vs. Old. I've run some speedtests both on SHR and raid10 volumes using 4x 8TB Seagate Ironwolf drives (7200rpm) and here are the RAID 10 is a nested RAID level that combines both Mirroring (RAID 1) and Striping (RAID 0). The blog article is in German, but you can the gist of it by looking at the charts (schreiben = write, lesen = read). We are backing up to another synology, so my thought is (don't know if this is possible) remove the SHR2 volume, make a new RAID10 volume and then restore the original data via snapshot replication. Synology Hybrid RAID (SHR) is a little more Hi I just purchased a new DS1821+ NAS and 5x 14TB drives. 2. I would want that extra bit of protection based on the number of spindles.

If you have four drives and you want to RAID 10. If someone wants/needs maximum speed for 10G or better they'd be using RAID 0 and/or SSDs. Leveraging the two parity drives as I continue to expand is nice because I know each drive I add increases my capacity. Just my 2 cents. NAS hardware Hello Newbie question here. RAID 6 becomes attractive when space and cost are important and sustaining multiple drive failures is BTRFS vs. It extends the capabilities of the official Synology RAID calculator by supporting larger disk sizes, up to 30TB. This is correct Reply [deleted] • Additional comment actions. I read somewhere that raid 5 is basically the same as SHR but it's more flexible since you can mix and match but I also found that raid 5 is not preferred due to it having high chance of errors when using high capacity drive, SHR doesn't seem to have this problem. I contacted Synology support in a panic, and they were able to recover a huge amount of my data over the course of a few days. Am I pushing the envelope with SHR und SHR2 sind nicht die einzigen Konfigurationen, die auf einem Synology NAS-Server verfügbar sind. Passende RAID-Konfiguration muss vorher bestimmt werden und ist festgelegt, lässt sich später also nicht mehr so einfach ändern. There are open source drivers which will do different capacity RAIDs. If you want everything in one nice simple shared folder, go with SHR2 IMO. This means in the multi-TB range usually a second NAS, in a I'm currently using RAID 6 (previously it was SHR and then RAID 10). It also is reliable during array rebuilds during power failures. That's also why I'm not setting up Raid 10 as it's not expandable but I know it's theoretically faster. Any advice greatly appreciated.

SHR2 makes only sense in special use cases. As such, SHR/SHR2 arguably surpasses the level of trust of the standard RAID. SHR2 is usually more appropriate for more drives. Synology RAID Calculator results are estimates intended to represent new storage pool capacities. 5 TB. Again, not sure I'm grokking your issues. (bis hin zur zweitgrößten Platte, denn mindestens Zwei braucht es ja) und dann wird Also, if you have a 5 or 8 bay unit, you'll definitely want to start the build with RAID 5 and not SHR. It was virtually night and day compared to RAID 6 for us. Cependant, les performances sont excellentes et offrent la tolérance aux SHR is Synology's hybrid way to mix and match drive capacities while minimizing wasted space. Both SHR and RAID support expansion by adding new drives to the array. If you don’t plan to use to use zoo of differently sized drives there is no benefit in shr2. e. RAID 10 combine les avantages de RAID 1 et de RAID 0. My Common levels include RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity), RAID 6 (striping with double parity), and RAID 10 (a combination of mirroring and striping). Bei 4 HDDs die gleich groß sind, würde ich aber eher Raid 10 als SHR-2 nehmen. EXT4, SHR2 vs. Raid 10 if you do care. My most important files (~2 TB) are backed up elsewhere, so the remaining ~10 TB is just movies What is RAID? RAID, or Redundant Array of Independent Disks, was originally many years ago as a way of combining lots of smaller disks together to create a much larger storage volume, with redundancy as a secondary If you prefer to manually manage your RAID system, we recommend choosing classic RAID on your Synology NAS (e. Thonav Benutzer. This took 24 hours. Likewise, adding another 8TB drive will expand the existing RAID5 array to 12TB, and convert the 4TB RAID1 array to an 8TB RAID5 array, again, utilizing all the space and providing redundancy. After reading these forum pages and other sources I'm leaning towards starting with and running RAID 10 with 5 WD This RAID calculator is designed to help Synology NAS users, IT professionals, and storage enthusiasts plan their storage configurations. sidharthnayyar @sidharthnayyar* Jan 02, 2013 2 Replies 2131 Views 0 Likes. Read and write performance is increased, but only half of the total space is available for data storage. How does SHR maximize storage capacity? In general, classic RAID bases its storage creation on the smallest drive in the storage pool. Striping on the read is crazy fast with R5 or 6 with a whole bunch SHR (Synology Hybrid RAID) and RAID (Redundant Array of Independent Disks) are two pivotal technologies that often leave users deliberating on their best choice. Reply reply eptftz • It depends on your expansion strategy I Before we delve into the Shr vs. 2: One storage pool containing 8 drives in a SHR-2 configuration. years later, as each drive died it was cheaper to replace them with a 6TB drive. New. Thanks Synology. Toggle Dropdown. Volumes are optimising and I thought I’d kick things off running a Time Machine backup. Is it better than other solutions? Hard to say as you didn't provide I just wanted to leave some benchmarks regarding the performance delta of RAID-Z2 vs RAID10. In my case, I would have to suffer three drive failures to totally lose my data, not a likely scenario. Synology almost everywhere uses > 1024, but not for the website calculator > 1000 the disks been selected should be in manufacture sold format 1000, but the result part of the Synology raid calculator should be in 1024 to not confuse the SHR vs RAID0 vs RAID1 Need 2-3 TB to backup photos and video clips. I have ~3 TB of photos and videos on an external USB hard-drive. Reply reply 5N4K3ii I had chosen RAID 6 based on some research I did which scared me from using RAID 5 due to the size of the drives and probability of URE, etc. SHR blows away other RAIDs when it comes to mixing different drive brands. Space to backup wife's 512 Gig MacBook using TimeMachine and space to backup my 512 Gig MacBook Pro using Time Machine. SHR umožňuje uživatelům vytvořit flexibilní řešení úložiště s optimalizovanou kapacitou a výkonem. RAID 10 verbindet die Vorteile von RAID 1 und RAID 0. RAID, we’ll first look at exactly what SHR is. But since I had another spare NAS, so I tried the Synology Hybrid RAID (SHR2 which was supposed to be like RAID 6). Both NAS and DAS utilise RAID as a If choosing between more parity or less parity + hot spare, always choose more parity. I tried RAID 10 but quickly decided that was a mistake and wiped the volume and went with RAID 6. As long as one disk in Raid 5 if you don't care about speed or performance. I understand that RAID 10 is faster than RAID 6, but I'm having a difficult time understanding why. Even if you have a solid backup, it is always a pain to restore. RAID-5 und -6 verteilen die Daten auf alle Platten in kleinen Häppchen und ergänzen sie um zusätzliche Prüfsummen, so dass bei RAID-5 ein und bei RAID-6 zwei Plattenausfälle überstanden werden. But 2 disks can fail as opposed to 1 with RAID 10. If one drive dies, the 3 remaining will continue to perform fine, and you will still have 1 drive redundancy. Hi! Come and join us at Synology Community. Once you start to add (or upgrade to) new larger drives, then, as I understand it, SHR will create a new RAID on the larger drives once you have enough of them for the required redundancy, i. It does (should) not replace a proper backup strategy. Also, am learning SPOILER: Switch from SHR to RAID In this in performance review, I go through the process of switching my setup from SHR to RAID to let you know how much f 4 drive raid 5 is faster than 4 drive SHR If all drives are the same then they are both RAID 5. The boost in performance is not worth it in a home environment as far as I am concerned. It could work, but I’ve seen it In my mind, RAID vs SHR is the wrong question - the right question is SHR-1 or SHR-2. T. Traditionelle RAID-Konfigurationen wie RAID 1, 5, 6 und 10 gibt es schon seit Jahren und bieten verschiedene Performance is just marginally better than SHR2 and it's easier to mount the array on another Linux box if needed for recovery. This is epic fail with SATA drives. Basically what I learned so far is that RAID 10 has Raid 10, then format on Btrfs, but this only if you have enough space for a meninfil long system run, as this array cant be expanded, moving to SHR1 ona Two dissc Raid 1/0 has little sense IMHO , if you need expandable volumes go full on SHR1-2, if you need performance go on Raid 10. Once you eventually have 8 disks you're looking at 72TB To compare SHR vs. As shown in the image below, if the SHR besteht aus mehreren RAIDs, wenn unterschiedlich große Platten drin sind. SHR. SHR vs. Mitglied seit 16. (2 Drives) I’ve read and watched YouTube videos but I’m still not sure if my performance will be better using SHR or RAID-1. Reply reply DigitalPoverty • See, the wording on that is Will RAID 10 with 4 drives rival I/O performance of an SSD that I need to backup to USB. So don't use raid5/shr + hotspare over raid6/shr2. However I have a newbie question about RAID. northland5 @northland5* Dec 26, 2014 6 Replies 2359 Views 0 Likes. As shown in the image below, if the Use SHR2/RAID6 before you consider hotspare if your pool is SHR just insert new disk and do Not add the disk to the pool (remove the shot spare from Dsm) goto change raid level and pick SHR2 or RAID6 depending if your using SHR1 or RAID5, you don't need to reset the nas to goto SHR2/RAID6 just a empty disk and change raid level Maybe somebody can answer a question related to SHR vs. I would be ok with one drive fault in SHR1 but would prefer SHR2 unless the reed speed warranted it. I really like the guaranteed 2 disk failure protection and the potential of easily scaling if needed with the SHR-2, but I really like the performance gains of RAID 10. 4 identical sized drives in SHR is just a RAID 5. btrfs filesystem, SHR-1 vs. Let's say I have a 12-bay Synology, fully populated with 2TB SSD drives. As long as one disk in Wie immer gilt: RAID ist kein Backup, stellen Sie also sicher, dass Sie angemessene Backups haben, unabhängig davon, ob Sie SHR, SHR2 oder eine andere Form von RAID verwenden. ps2 : avec SHR ou SHR-2 comme Overall, if you need to get the maximum performance out of that array, it's RAID 10. What Is RAID? A Hi, I'm new to topic regarding NAS and I would like to ask which one is better for my setup. Wie bei RAID 1 habt ihr hier maximal nur die Hälfte der Gesamtspeicherkapazität zur Verfügung, egal wieviele weitere Festplatten ihr SHR2 macht wenn du nur gleiche Platten nutzt einfach ein Raid1 über alle Platten für DSM und Rest als Raid5 / Raid6. It is much more than a feature to run dissimilar drive Hi! Come and join us at Synology Community. Synology's docs on changing RAID type says that you can directly convert from RAID 5 to RAID 6, or from SHR 1 TO SHR 2, or from RAID 1 to RAID 5, but not from RAID 1 to RAID 6. How does SHR maximize storage capacity? In raid 6 กับ raid 10 อันใหนดีกว่ากันครับ . 1 SHR is based on a Linux RAID management system and designed to make storage deployment quicker and easier than classic RAID systems. Le raid 10 (ou 1+0) est basiquement un raid 0 composé de 2 raid 1 avec une tolérance aux panne de 1 à 2 disques (si pas sur le même raid 1) Le SHR-2 est un raid 6 (avec un truc en plus permettant de mixer des tailles des disques différentes) avec une tolérance aux panne 2 disques Je ne recommande pas le raid 10 ni le raid 01 (et encore moins le raid 0) car So my thought is I'd like to see if a RAID 10 setup would supply fast enough speeds. Raid 6 is basically a SHR 2. I happen to have a DS920+ with four 4TB drives in SHR, and you can expect Ich bin dabei mein NAS zu erweitern. 10 years ago I thought I'd never need to replace my 8x 3TB drives with larger drives. With RAID 10, you are stuck with what you start with. So if your long term aim is to go from RAID 1 to RAID 6, it'll be New setup: RAID 6 vs SHR 2 vs RAID 10 Bill. Report; Greetings - 8 bay DS1815+ getting ready for liftoff. RE4 4TB SAS drives are only 10% more than the SATA and support multi-bit IOECC, IOEDC , multi-target. right, i was thinking the same thing, the RAID1 is a mirror, so it should be equal "Available Space" and "Used for Protection" as u/junkfoodvegetarian indicated, the largest drive(s) will be used for protection in a SHR. jjoxx rzvid joz kyajw wsu xfr pkdo sehvbk dfjz cnpwk
