The Alienware X17 R1 does not have Hard Disk Drives (HDD). RAID 0 shares its data 50 50 between two Hard Disk Drives to improve system read/write speeds. Hi to this user to user discussion forum. Otherwise, stick with RAID 0, but have good backups - not because of the RAID 0, but because you should have them anyway. even partitioning the RAID 0 virtual disk into multiple partitions would not serve your purposes. So I'd only do a rebuild if you specifically want to treat your storage as completely independent devices, i.e.

I've seen several threads here saying, 'I ordered my system with a small SSD and large HDD, but I don't know how to store things on the HDD.' Evidently some users are unfamiliar with the concept of multiple drive letters and the ability to move data to drives other than C. And that may be why Dell only sells multiple disks that way. If you'd prefer to have all of your storage available as a single disk rather than two independent disks for your purposes, then RAID 0 seems like a reasonable strategy. RAID 0 or not, I'd still plan to have frequent, reliable backups, including image backups of at least my OS partitions. But I don't think that should necessarily change your strategy. of writes, so you wouldn't want RAID 1.RAID 0 does double your chance of data loss since a failure of either SSD renders the data on the remaining SSD unusable. But if you've got 2 SSDs, why wouldn't you RAID them? I backup, I'm not worried about one failing. Wooo Hoo! that's fast ! I know I don't need anywhere near this for what I'm doing. no idea if block size had anything to do with it. While I was typing this, I rebuilt the RAID w/256k and that seems to have gotten me back to the original speeds I had a year ago. How much a difference does the right or wrong block size make? Any impact on SSD life? All I use the Server for is Time Machine and CCC imaging for my other 3 Macs. Most of my music and photos range from 6-25 MB files, videos are HD, a few are 25 Gb, most are around 2 Gb. as far as file handing: Right now it's my Media Server for Photos, Movies & Music and for Image Backups for my other Macs. 😎 I'm an Engr and I love tinkering, I used to build my own PCs, then the world changed and I discovered Mac. I mainly wanted to see how fast I could make it go.

Although, I have seen some high-end SAN units that can alter the block size, although this technique is incompatible with all versions of Windows except Vista. In virtually all cases, this is 512 bytes and is not changeable. The block size would refer to what sector size the RAID controller abstracts to the computer. If you're not doing either one of these, then a good overall size for many applications is 64K. For primarily large, sequential accesses like video files, a higher stripe size like 128K is recommended. If you access tons of small files, a smaller stripe size like 16K or 32K is recommended. So, for use cases such as databases and email servers, you should go for a bigger RAID chunk size, say, 64 KB or larger. Here you want a single I/O to be dealt with by one drive with one seek action rather than be spilt between more than one drive and multiple seeks. For this use case smaller RAID chunk sizes (for example, 512 bytes - one block - to 8 KB) fit the bill because you want to take data from one drive while the others seek the next chunks to be read.Īt the other extreme in terms of use cases would be running a database in which the amount of data read on each operation is small, say, up to 4 KB. That means you will need to spread data across individual drives as much as possible. For example, if your business works with lots of video or large image files, you will want to ensure maximum throughput.
