No, no SSD recommendations, please. ;-) AFAIK, the WD VelociRaptor 1TB (WD1000DHTZ) - was/is the fastest HDD (SATA3 connection). I searched the web, it looks like it's not longer sold - at least I can't find an online-shop which sell this HDD still. Which HDD is now the fastest (reaction/access time, data transfer) available HDD? (I searched the web, but I'm not smarter now.) With 1TB or max 2TB (AFAIK, Windows can be installed just on HDDs </= 2TB). Thanks. |

If this is in a new PC then consider a small boot disk and a large "data" disk. (Noting of course if this is for a SETI cruncher the overall performance difference between the slowest and fastest disks is almost too small to measure - once a task is loaded everything happens within the processors and memory.

I'm an old man and don't 'trust' SSD's. ;-) The HDD should be for a gaming PC. I know I can't increase the FPS with a faster HDD, but the reload (new area, next level) should be so fast as possible. With a few online games it's important... |

I'm an old man and don't 'trust' SSD's. ;-) Then I suggest you read this article- Tech Report SSD endurance experiment. SSDs are limited in the number of writes they can handle, reads are limitless. Reliability of SSDs in general isn't an issue. Just like HDDs there have been some that haven't been up to the job, but they are very much a minority. I know I can't increase the FPS with a faster HDD, but the reload (new area, next level) should be so fast as possible. In which case an SSD is the only option as HDDs are just incredibly slow by comparison. If speed isn't important, use a HDD. If it is, use a SSD. The fastest consumer drive is the WD Velociraptor. As HDDs go it's performance is excellent. Compared to a SSD it's woeful. The first link shows SSDs v a HDD, the HDD is down the bottom. That comparison is 2 years old. The second link shows current hardware. The benchmark is for 128kB sequential reads, something HDDs are pretty good at. When it comes to random I/O SSDs are even faster compared to HDDs.

Personally, I am a SSD convert. However, I help maintain the Family PCs and the HDDs I encounter do their job. It really comes down to personal preference. A quick search on Newegg or TigerDirect will give you an idea of the quality and performance of any drive based on user ratings. In the end, BOOT and application loading are greatly enhanced on SSDs vs HDDs. Just my 2 cents worth.... Peace and happy crunching... |

What do you mean with fastest, Dirk? Access speed? Read speed? Write speed? Rotation speed? Here are 4 terabyte HDDs, 3.5 inch, at speeds of 5,400/5,900/7,200 rpm. Apparently the German Alternate site does not allow further filtering down on rotation speed. A cheaper alternative, but faster because of the on-board memory are these Hybrid HDDs. Though at a slower rotation speed, they do have 8GB of NAND memory on board in which the drive will store the most used programs, so they're accessed quicker. |

In the end, BOOT and application loading are greatly enhanced on SSDs vs HDDs. Greetings Louis, I used to buy from TigerDirect almost exclusively. I found out recently that they have been bought by a company called PCM and they (TigerDirect) are being downsized to nothing. PCM is pulling a Micro$oft and putting TigerDirect out of business. They have virtually nothing left. They have 3 or less of most everything I looked for. Yes, Micro$oft has been known to do the same thing to at least one company I know of. The company was in Carlsbad, CA and they found out that their HDD compression software was integrated into MS-DOG v6.0 They sued M$ and won and that was when MS-DOG v6.2 came out shortly after. M$ turned around and bought the company and put it out of business. I can no longer remember the name of the company. I will be going to Newegg and Amazon from now on. Keep on BOINCing...! :) [edit]Or was it MS-DOG v6.2 and then v6.22? ;) Memory fading way to fast. ;)[/edit] CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS? "What a piece of junk!" - L.

If you want the same performance as a WD Raptor in a HDD the you will need to look at SAS drives instead of SATA. SAS drives have several spindle speed options but you would probably only be interested in 10K & 15K RPM models. Depending on the number of SAS ports you need. You can get a SAS controller that only uses a PCIe x4 slot. Personally I went from raptor drives to SSD. You could use 2 SSD in RAID1 if you didn't trust them. A slow SSD is still faster than the best HDD. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

M$ turned around and bought the company and put it out of business. I can no longer remember the name of the company. Once again, bad information about Microsoft and it's history. Yes, MS-DOS 6.0 came out with hard drive disk compression. As with a lot of DOS utilities at the time (e.g. Defrag was a slimmed down copy of Speedisk from Symantec; VSafe.com was from Central Point Software, etc.), Microsoft had approached Stac Electronics to include Stacker compression in DOS. Stac demoed their product for Microsoft, but they never came to a deal. Microsoft then developed their own in-house solution for disk compression to include in DOS. In rare circumstances, disk corruption would occur in the original release, called DoubleSpace. Microsoft fixed this bug in MS-DOS 6.2. In the meantime, Stac Electronics filed suit against Microsoft claiming they had found DoubleSpace infringed upon their code. After a full review, a judge ordered Microsoft to stop shipping copies of DOS with the infringing code, which included MS-DOS 6.0 and 6.2 (at this time, IBM and Microsoft were alternating version numbers; IBM had PC DOS 6.1). Microsoft quickly released MS-DOS 6.21 which removed disk compression altogether, but still supported DoubleSpace if you installed it previously. After Microsoft rewrote their code, they re-included disk compression in MS-DOS 6.22 as DriveSpace. Microsoft never bought out Stac Electronics. Stac Electronics moved their headquarters from Carlsbad to Estonia. After changing their product lineup, they changed their name to Previo. After the dot com bubble burst, they went out of business. All their assets went to Altiris, and all remaining cash going to shareholders before disolving. https://en.wikipedia.org/wiki/Stac_Electronics#Microsoft_lawsuit |

I could swear that what is in my head about that was correct. :| But, as mentioned above in the quote, memory is fading. Either I read, or heard on the radio, what I stated was correct, or I am remembering wrong. Whatever... At this time I will state that I stand corrected only because one cannot argue with Wikipedia. If they say it is so, then so be it. All I ask is that you do not continue to rub my nose into it. And besides, what you refer to as 'bad information' or whatever from a month or so ago is flat out wrong. It was, as I told you before, speculation, nothing more. So I ask you to step off your high horse and leave me alone from here on out unless I state something that is absolutely wrong as fact and not speculation. Ok? :) Keep on BOINCing...! :) CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS? "What a piece of junk!" - L.

I used DoubleSpace once... ... and never more! Would "They" warn you not to use that on a highly fragmented disk? No, they would not. I was fascinated by the novelty and compressed all my data directory. No back-up... All my life till then going in compression without safe net. That was at that time my faith in Microsoft. That was at time my imprudence level. Hit return and... bang! All my data lost in 1 second. All my electronic life gone. One of my worst nights ever. Then in the morning I called MS. Reverted somehow back. All data saved and safe (and back-uped). "Defrag the disk first next time", they advised me. There would be no next time. Ever. Never compressed a partition any more. Not even for back-up purposes. Always raw, original format. Sleepy |

Either I read, or heard on the radio, what I stated was correct, or I am remembering wrong. Whatever... No worries. I just dislike misinformation. I don't care who hates Microsoft, I just think it is important to have the facts straight. All I ask is that you do not continue to rub my nose into it. Interesting that my attempts to correct bad information come across as rubbing people's noses in it. This would be why I stopped posting so much. Apparently people take me the wrong way or I suck at communicating with people, or both. I guess rather than impressing people with my knowledge, people would rather get defensive about being corrected when wrong. /shrug And besides, what you refer to as 'bad information' or whatever from a month or so ago is flat out wrong. I stopped reading the Windows 10 thread altogether. The entire thread is filled with speculation based upon bad information, and promulgated as fact by other prominent members of the message board. I'm far too busy with real life to write dissertations, complete with links to supporting sources, just to prove people wrong. In short, I don't care anymore. It was, as I told you before, speculation, nothing more. So I ask you to step off your high horse and leave me alone from here on out unless I state something that is absolutely wrong as fact and not speculation. Ok? :) I'm not on a high horse. I would urge you to get to know me better; to understand me better, before making such a judgment call. It's easy to point out flaws in my character and think me as just another jerk on the internet. It's another thing altogether to understand that I'm simply trying to be helpful. I feel like I should apologize for my character, but I'm not really sorry about who I am. I am sorry that you and others can't accept me for who I am. Sorry to drag the thread so far off course. I'll stop posting in this thread. |

If you want the absolute fastest then probably the Intel 750 Series NVMe PCIe SSD's that plug straight into a PCIe x4 slot would be hard to beat. You need a large bank balance though. |

I have used two SSD on one Linux box, one OCZ and one Samsung. They both failed after a while and now I am using a 1 TB Seagate Hybrid disk I also have a 2 TB Hybrid disk on my Windows 10 PC by HP. I prefer slower but more reliable disks, once a SSD has failed it cannot be recovered, you lose all your data. I have a 40 MB Maxtor disk on my Olivetti AT&T PC running UNIX System V vintage 1987, and it still works. Tullio |

I have used two SSD on one Linux box, one OCZ and one Samsung. They both failed after a while and now I am using a 1 TB Seagate Hybrid disk I also have a 2 TB Hybrid disk on my Windows 10 PC by HP. I've had at least a half dozen HDDs fail over the years. No SSD failures yet. I prefer slower but more reliable disks, They may be slower, but they aren't more reliable. Depending on how the information is gathered & reported SSDs can come out way in front for reliability, or HDDs come out slightly in front. So overall SSDs are probably more reliable, but not by a large margin at this time. So overall, SSDs and HDDs are roughly on par with each other for reliability. once a SSD has failed it cannot be recovered, you lose all your data. Not true. It depends on the type of failure. Just like with HDDs- when they fail sometimes the data can be recovered, sometimes it can be recovered for a massive cost, and sometimes it's lost forever. Grant Darwin NT |

Have to agree SSD's all the way now. My first hands-on experience is when I bought a Surface Pro 3. I was amazed how fast it booted. So when I built my latest box (10/15), my boot drive is a Samsung 850 Pro (512GB). Couldn't be happier, and it has a 10 year warranty. HDD's don't come with that. And put a 256GB SSD in an old laptop, and it's like a new machine. |
