    Intel X25-M Impressions

    Every hard drive in existence in the history of the world needs to be defragmented for optimum performance. With SSDs, it is even simpler, since you only need to do free-space consolidation. But at least you have clarified the limits of your capabilities.

    Intel X25-M Impressions

    On the OCZ forum, there is a lot of discussion of the benefits of free space consolidation for improving write speeds for their SSDs. http://www.ocztechnologyforum.com/forum/sh...ead.php?t=52329 Diskeeper shows this comparison for their Hyperfast software: http://theovalich.wordpress.com/2009/01/28...zation-utility/ But this indicates that the X25-M is much more resistant to that type of slowdown, though it seems to be dependent on which firmware you have: http://www.diskeeperblog.com/archives/2008...fast_is_al.html Have you tried free space consolidation? It won't do anything for reads, but could help the writes.

    Lifespan of SSD drives?

    I have heard that comment made, but if you check it out (and even better, try it yourself), you will find out that free space consolidation in fact restores the speed to the original value. That is why people do it. I think the better question is that as wear-leveling shuffles the data around, does it continue to work in the long run, over the course of many months or years? The returns are not in on that one yet that I have seen.

    Lifespan of SSD drives?

    I think you will see an effect in a month of normal use. The biggest reason is the need to consolidate free space. That is not the same as defragmentation, but you can do both if you want, somewhat against the conventional wisdom. http://www.ocztechnologyforum.com/forum/sh...ead.php?t=52329 I think the Intel SSD is something of an exception however, and I don't believe it is recommended to do anything along the lines of free-space consolidation with that one, but you may want to research that also. Of course, it helps to do the usual tweaks well-known to all SSD users also; see the OCZ forum for those too, or use the SSD Tweak Utility, for an easy-to-use GUI method. http://www.ocztechnologyforum.com/forum/sh...ead.php?t=49779
  5. You are grasping at straws for an explanation, and got the wrong one. I always bought Maxtor, and have had over a dozen of them. I never had a Maxtor failure and they always lasted the life of the PC which was around 5 years, until they got to the 100 GB/platter level. Then, the two drives I lost were early in the production run, when failure rates are always high. That was not long before they were taken over by Seagate as I recall. But you might as well blame it on Seagate if you want to. But I still have the replacement Maxtors (250 GB and 300 GB) going strong, around 5 years later, not to mention the six-year old 80 GB Maxtor I just removed from active service to put in a standby PC. For comparison, when I bought Seagate, WD and Quantum (one of each), I got failures in the first year. The difference was significant, though I think reliability has improved greatly in recent years for all of them, and I have no problems now. But I also now use well-cooled cases, uninterruptable power supplies and good (series) surge protectors.

    Which? 500gb internal HD

    I don't see any for that Seagate at all, only data sheets. I think you are comparing the old stuff.

    Which? 500gb internal HD

    The data rate is determined by the density and the rotation rate, and Seagate has the highest density at the moment, and the rotation rate of 7200 rpm is the same for all of them. If you mean access time, that can vary depending mainly on how quiet they want the drive to be, but that doesn't affect the data rate. There is an even smaller effect due to buffer size, but 16 MB is plenty.

    Which? 500gb internal HD

    The Seagate 7200.12 is the latest and greatest. It is the only single-platter 500 GB drive that I know of at the moment. http://www.newegg.com/Product/Product.aspx...N82E16822148395 And it does not seem to suffer from the firmware problems that plague the 7200.11 1.5 TB drive, though I don't have either.
  9. Are you going to use it as a boot drive? I have the SAMSUNG Spinpoint F1 HD103UJ (1TB), which is very quiet and cool, and has lasted for 8 months with no problems thus far. If you are just storing videos, I would get the SAMSUNG HD103UI, which is the 5400 rpm version and should be even quieter and cooler. It should last a long time, but any hard drive can fail prematurely, so you take your chances with any of them. http://www.newegg.com/Product/Product.aspx...N82E16822152135 For comparison, I also have the 640 GB dual platter Western Digital drive (WD6400AACS) and I think the Samsungs are cooler and quieter for an equivalent number of platters.
  10. The problem with disk drives as a long-term storage medium isn't so much about their magnetic retention as it is mechanical problems. After sitting unused for a long time, the bearings often fail on start-up. I think it is a problem with the lubricants, though it varies by model. But you won't know for sure until it is too late. I do know that a lot of hard drives that normally operated continuously failed shortly after January 1, 2000. That is because a lot of computers were shut down to avoid Y2K glitches. Then, when they started up again, the drives failed. I don't think you would expect to have a problem sitting on the shelf for a couple of years, but 10 years might be pushing it. If you don't want to keep the drives running, chances are the best bet is to store two backup drives on the shelf, and check them every six months or so at staggered intervals. Then, when one or the other of the drives fail, you can buy another one. Maybe the RAID experts here can give you more guidance.
  11. It is surprising the number of people on a disk drive forum who don't know the difference between the base 2 and base 10 number systems, and who therefore don't know how hard drive sizes are measured. I would almost expect it on Newegg, where every-other post complains about it, even though every third post explains it (or tries to). According to the disk drive manufacturers, 1 MB = 1,000,000 bytes, according to the usual base 10 number system we use every day. But according to the software people, who long ago adopted the binary number system, 1 MB = 1,048,576 (2exp20). Therefore, since they consider 1 MB to be larger than we use in everyday usage, there will be fewer megabytes per disk drive. That smaller number is what is reported in Windows.
  12. Even if you don't disturb the actuator arm, any dust or contamination will crash the head and that is the end of the drive. I would be surprised if you get more than 5 minutes.
  13. Try connecting it to one of the internal SATA ports. It could be an incompatibility with the JMicron chipset.

    Review of 2.5" drives

    The best prices and selection (at least for the U.S.) appear to be: http://www.googlegear.com/jsp/ProductList....goryCode=011006 I bought the 80GN 30GB Travelstar (4200 rpm), which is much faster and quiter than the 10GB that originally came with my X20, and at least as long battery life.
