| 1331183 | 2013-03-04 21:05:00 | I have 2 SSD disks running in RAID 0. Can I defrag them without losing everything? I know you shouldn't defrag ssd's |

| 1331184 | 2013-03-04 21:44:00 | Yes you can but no you shouldn't. Why would you want to ? I'm thinking of getting a 2nd one and raiding them also, just because it's cheaper than getting a bigger one. I was wondering about trim support using RAID myself. What I do is have a convential hard disk dedicated to backups and windows scheduled to backup the SSD once a week, makes me feel safe even if I have never used the backup. |

| 1331186 | 2013-03-05 01:58:00 | DO NOT defrag an SSD period, all you are doing is accelerating the wear which will decrease performance, the only way I know to increase the performance is to image the logical drive, then erase and re-image down.... If disk performance really is a big issue for you, their are a couple of options.....buy more RAM and create a RAM Drive, or purchase a PCIe Expansion Card with RAM on it... |

| 1331187 | 2013-03-05 02:15:00 | Buy a hard drive and then defragment it, instead. | Agent_24 (57) | ||
| 1331188 | 2013-03-05 02:18:00 | I have been useing ssd's ever since they became available. I have always defraged them every three or so months. My computer always seems to run faster after the defrag. May just be my imagination, but they have never caused any problems or damage. I notice the warning that says MAY cause this or that. I believe the warning is to protect the manufacturer. In my case I'm more concermed with upsetting the RAID. |

| 1331189 | 2013-03-05 02:20:00 | "Being careful" doesn't usually exist in the same neighborhood as "RAID 0" Personally I avoid RAID0, because you're doubling the chance of a disk failure destroying all your data. The exception is temporary files, browser caches, memory page files, or other non-production temporary files that are always rebuilt on restart. ("TempDB" for SQL server). Still to each his own. |

| 1331190 | 2013-03-05 02:21:00 | Yup, definitely just your imagination. Defragging orders the files sequentially, and together, on a drive. Fragmentation occurs when one single file is stored in dozens of places all around the HDD. The "slow down" is the seek times as the head physically moves across the drive to the different locations. SSDs are flash-based, they're like a thumb-drive, you don't defrag them. It's a genuine warning, there's no need to do it, and there's definitely no performance increase. |

| 1331191 | 2013-03-05 02:29:00 | I'm not concerned with backups. The only reason I use RAID 0 is to boost r/w speed. It doubles their speed. I am told it will double again if a third disk is added. |
