Solid State disk for a desktop system C drive?
Is there any reason why I shouldn't use a sold state disk as a C drive on a high performance desktop system? 36GB would make a fine C drive for my work. Newegg has 36GB solid state disks starting at 70 bucks. They feature screaming read rates. The write rates are a little slower but still faster than a 7200RPM hard disk. Latency should be zero but I know that something has to happen in the write cycle for a SSD and the summary specs don't list delay times which would be a form of latency. I do Photoshop. I'm thinking of using the SSD for a second disk and dedicating it to swap, temp, and PS work files. That way, if it dies, I haven't lost any work. comments? -- Al Dykes News is something someone wants to suppress, everything else is advertising. - Lord Northcliffe, publisher of the Daily Mail |

In fact I have done this recently witn an OCZ 30GB drive. Not that much faster, but noticeable. Newegg has 36GB solid state disks starting at 70 bucks. They feature screaming read rates. The write rates are a little slower but still faster than a 7200RPM hard disk. Latency should be zero but I know that something has to happen in the write cycle for a SSD and the summary specs don't list delay times which would be a form of latency. The one thing slower is small accessed. I believe these SSDs have something like 128kB sectors (internally, not visible). So if you do very small writes or reads, the data rate may drop significantly. I do Photoshop. I'm thinking of using the SSD for a second disk and dedicating it to swap, temp, and PS work files. That way, if it dies, I haven't lost any work. Also a good idea. However SSDs should be at least one order of magnitude more reliable that well-treaded HDDs. comments? Go for it. Arno |

Have you tried google before posting? Check this out. http://internetbestsecrets.com/2007/...r-ssd-use.html I think this is now mostly obsolete information. Unless you have a system that swaps a lot, you are not going to hit the FLASH life expectancy within 5 years or so. Incidentially you can get SSDs with 5 year and more warranty time. Some ElCheapo SSDs may still be affected though. The solution should be to get a better SSD IMO. Arno |

Is there any reason why I shouldn't use a sold state disk as a C drive on a high performance desktop system? Depends on the technology and the OS. Win and Vista both use it pretty intensively for temporary files and some solid state disk technologys dont have that may write cycles. 36GB would make a fine C drive for my work. Newegg has 36GB solid state disks starting at 70 bucks. They feature screaming read rates. The write rates are a little slower but still faster than a 7200RPM hard disk.

It may not last very long given the limitations on the writes. |

I have an SSD as main drive on my desktop and works well. Newegg has 36GB solid state disks starting at 70 bucks. They feature screaming read rates. The write rates are a little slower but still faster than a 7200RPM hard disk. Latency should be zero but I know that something has to happen in the write cycle for a SSD and the summary specs don't list delay times which would be a form of latency. I do Photoshop.

I would put the OS on the SSD but it's worth experimenting, as there is little usage history of these systems. If you do, make sure your backups are reliable, as they should be. You may have different priorities, but I have only the SSD drive in that system and enjoy the silence and the low heat inside the box. Anyway, have fun and if you don't mind share your experience when you have time. |

Are there any SMART extensions that are peculiar to SSDs? My OCZ does only give temperature and vendor stuff. Goven that most HDD measures (including reallocated sectors) do not make sense, this is not surprising. I am a bit disappointed though that it does not support self-test. I am back to a complete, timed read with error detection for the SSD. Arno |

Goven that most HDD measures (including reallocated sectors) do not make sense, How would bad areas of memory be accounted for? The problem here is that SSDs do not use the 512 byte sector size (instead something much, much larger, like 128kB) and do not use the HD reallocation mechanism. I would like to see something like "failed reads" or "ECC recoverd bytes", and it is possible that the drive actually states them, but in vendor specific attributes that at least smartctl cannot interpret.
