What is the difference between SHR and RAID? https://nascompares.com/2019/10/04/sy... • Synology Hybrid RAID or SHR, has been around for quite a while now, and though it has not made the big impact that Synology NAS’ Btrfs file system has, it is still an increasingly popular choice for many when it comes to protecting their hardware and their data in a Hard Drive Enclosure. Both NAS and DAS utilise RAID as a form of protection from an HDD or SSD failing and the consequences of data loss that can follow. It should always be highlighted that both traditional RAID and SHR are NOT forms of Backing up and you should ALWAYS have an offsite or at the very least off-system backup in place creating real-time images and copies of your mission-critical data. However coming back to the subject at hand, which method of redundancy should you be considering for your storage array – RAID or SHR? • Order your NAS from the NAS Experts, - https://www..com/search/Synology_space_NAS_space_Drive/10-Synology • 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 priority. However with the large scale growth of Hard Drives these last 5 years and more, with Terabytes of data becoming available on single disks, the primary function of RAID has shifted towards data protection. • That isn't to say that pooling smaller drives does not still happen, but with drives currently available to buy in 14TB such at the Seagate Ironwolf NAS Drive, you can see why the purpose of RAID in an archive and cold storage is more about hardware protection. • Available in numerous types, but the most popular of which is below: • JBOD – Just a Bunch of Disks, not really a RAID in any shape or form. • RAID 0 – A method of combining two hard drives or more into a single GIANT volume of data, however, if you lose one drive, you lose all your data! • RAID 1 – Using pairs of drives, this will HALF your total capacity, but give you a complete and up to the second copy of all your data. Meaning if a drive fails, you have an EXACT copy ready to access. • RAID 5 – One of the most popular RAID levels, It requires at least 3 drives or more, data is written across the drives in stripes (waves) and across each stripe of data one drive holds a tiny nugget of data called ‘parity’ with is basically a coded blueprint of the data on the other drives in that stripe, then each stripe has the parity deposited on a different disk each time. The result is that if a drive fails, the system can re-build the data using the parity (blueprints) on each stripe. This can take time though and it should also be noted that the read and write of data in a RAID 5 is a little slower than normal as the system has to work out background calculations whilst writing data. • RAID 10 – Think of this as a combination of RAID 0 and RAID 1, or RAID 1+0. You require at least 4 drives and drives are paired up as 2x2. The result is that you have two hard drives whose capacity to added together, and another pair of drives creating real-time copies (again, up to the second) of all the data. Probably the most expensive of all the RAID types here in terms of cost per GB, but gives you much MUCH higher read and write speeds compared to other RAID levels. • Find out what is new in NAS by visiting me on the Blog - htto://NASCompares.com • Need Free NAS advice?
