Raid stripe size small files
Under NO circumstances do you initialize the drive, you will lose all data if you initialize the drive. Basically the "new" raid 1 must match your previously documented setting except for the stripe size. If you have multiple array sets, go into the logical drive menu and check that the "set boot drive" is correct logical array to boot from. Go back to the main menu , go into logical drive, choose the raid 1, properties, check that the setting match to original raid 1, except for the stripe size.

With hardware raid, stripe size is not physically marked off on an array set's disks, as are clusters in an OS format , there is NO slack due to the stripe size. My posts above concern changing the stripe size only performance, where file size or database records are a particular size, and would benefit from a size other than the default size; this basically is useful for specialty servers, or to correct a mistake in an initial array setup.
An example where a smaller stripe size increases performance would be with an Exchange server. Yes, you can change the stripe size on a particular array set without affecting other array sets on the same raid adapter.
Thanks pcmeiners, If it's not drive slack, how can I account for the difference between the 'size' and 'size on disk' values reported by Windows Explorer.
Is there something else I can tweak? With large files the only wasted space is on the last cluster the file uses, so if the file uses With small files under the format cluster size, there is wasted space with every file, with a 4k cluster, a 2k file wastes roughly 2k.
Post Reply. Which would you use if you were in my place? I personally consider 64KB and KB to be pretty small stripes already so I would use either one of those, we use much larger stripes for some of our customer products admittedly those products tend to hold exclusively large files Based on that, I'd suggest a 64KB segment size. Quote: I just wanted to get some recommendations Don't do it. The RAID 0 stripe won't benefit to random access enough to be worth taking the hit on the reliability.
For many most? If it makes you feel any better, one of my hard drives died in my home computer about an hour ago. Fortunately it's a mirror and I have backups. I just noticed that SSD for the OS is plugged in the Adaptec controller being a "simple volume" and not passthrough - does anyone know if I can just plug that SSD to the mainboard and boot it up? I need that 8th port for the RAID 10 :- - otherwise I might have to try clonezilla, but if that fails I am in for a lot of fun It has been a long time since I worked with an Adaptec controller, but I know that on LSI controllers a single drive is usually treated as a single drive RAID 0 and presented to the OS as a virtual drive and thus will not boot as a standalone drive if connected to a SATA port on a motherboard.
I'm guessing that the "simple volume" vs. If you clone it with clonezilla it will just make an identical bit for bit copy of it and you will have the same issue. In your case, going from a virtual disk presented from a RAID controller to a SATA motherboard controller, you will want to make sure that the proper driver more info here for your motherboard is present and enabled in Windows before you run the backup. Depending on how the Adaptec controller has configured your drive, you may just get by with changing this setting s and then moving the drive.

Stick with NTFS. Hi Northlandeng thx for the extensive answer. Northlandeng wrote: What Adaptec is describing is "strip", or stripe element, size so I would go with 64K in your case.
