![]() ![]() When you need to write to these previously used sections, data has to be erased first, slowing the process down. SSDs that don’t use TRIM (such as all USB flash media) get slower the more they are used, because instead of actually erasing old data, flash just labels those sectors as “clean”. It’s a good idea to regularly “revitalize” or “recondition” your SD memory cards, and SoftRAID’s certify can help you do that. Use certify to “revitalize” your SD cards Remember to use at least 2 certify passes 3 is even better. Whether it’s an SD, SDHC, or SDXC card, SoftRAID will let you know if your new card has any bad sectors on it that could put your data at risk. You can use SoftRAID’s certify feature to test new SD memory cards before you use them in your digital camera, video recorder etc. ![]() SoftRAID doesn’t just certify rotating drives. On Thunderbolt buses, certifying 4 – 8 disks at once takes only slightly longer than certifying a single disk. After you have certified a disk, you know that it can safely and reliably store your files. If you don’t take the time to certify a disk, you run the risk of losing all the data you put on it. But I'd like to hear some other opinions too.Certifying a large disk with SoftRAID can take a long time-often a day or two (or more)-but it’s worth it! The comment on the OP of this post seems to follow my line of thought-that if IOPS are important, more spindles are preferred. Or should I just RAID-6 the whole goddamn thing? ) Should I opt for two RAID-5 sets? As far as I know, the only benefit to this would be more storage space. How should I divide up the disks?ĭo I do three RAID-1 arrays, for maximum spindle sets?ĭo I do a RAID-1 and a RAID-10? RAID-10 has higher performance than just a plain stripe/mirror AFAIK, but if my workload performance is dependent on separate spindles, could this be unoptimal? It will be running vmware, though all of our other servers are running Hyper-V as a service. ![]() The server is mission-critical, but does not need to have 24/7 uptime. My idea is to get the stores and transaction logs on seperate spindles, and possibly even the OS itself on its own spindle. Ultimately, it will be running VMs hosting various services, such as Exchange, and others. I have a server with room for a total of 6 disks. ![]()
