Re: Website, CSF, and lots of attacks.
The computer still has an address for the data on a hard drive, but with greater fragmentation those parts are scattered across the platter/s and it takes time to seek the data and then read it.Comment

Re: Website, CSF, and lots of attacks.
I would say that even if there was 0 fragmentation a mechanical device is going to be slower than one that is electronic and having tracks on the inside platter and ones on the outside platter have to be considered on a hard drive. I think top maximum speed is 10,000 rpm's. A hard drive was part of the bottle neck and as a result we have the SSD. Complete load time for Widow 7 Pro and all other associate drivers and programs on my Legacy T400 is 53 sec. with a HD it would be a the minimum 120 sec.Comment

Re: Website, CSF, and lots of attacks.
The reason it doesn't affect read speed is because of the way they're designed, isn't it? No moving parts, no need to search for the sector, etc.Last edited by Spork Schivago; 09-25-2016, 08:35 PM.-- Law of Expanding Memory: Applications Will Also Expand Until RAM Is FullComment

With a normal hard drive, reading sector 1 would be quicker than reading sector 107. With a solid state hard drive, reading sector 1 is just as quick as reading sector 107.
The latest bottleneck is (was?) the SATA interface I believe. They have M.2 now which is even faster than SATA, if it's implemented correctly. If I understand it all, I think some companies use an M.2 connector but are just using the SATA stuff, so you only get speeds up to SATA 3 or something. But if it's done properly, you can speeds faster than SATA 3. I get a little confused in that area because I haven't had a lot of time to research it much.-- Law of Expanding Memory: Applications Will Also Expand Until RAM Is FullComment

Re: Website, CSF, and lots of attacks.
M.2 is a standard that can connect to PCI Express, SATA and USB.
They do 15,000rpm hard drives Keeney.Comment

Re: Website, CSF, and lots of attacks.
I guess I was not understanding you correctly, sorry.15,000 rpm that is impressive. The article I had read some time ago said the highest usable top end speed would be 10,000 RPM. I wonder if the 15,000 rpms is actually faster in operational use?Comment

Re: Website, CSF, and lots of attacks.
it is faster, they have been around for many years - if you use scsi.
i have some.

Re: Website, CSF, and lots of attacks.
This here...so M.2 is a standard and the standard sas it can connect to PCI-E, SATA or USB? It's up to the designers which interface to connect them to?
When they connect the M.2 socket to the SATA interface, they're limiting the maximum transfer rate of the drive to whatever the SATA interface is, correct? When they connect it to the USB interface, same thing. PCI-E is the fastest out of all of them, right?
Is there a good reason for buying a board that has an M.2 socket connected to the USB or SATA interface instead of the PCI-E interface, besides maybe cost?
With the PCI-E interface, we can have NVMe which fully utilizes the high speed PCI-E stuff and allow for that parallel operations, which we can't get with SATA and USB. Is that right?-- Law of Expanding Memory: Applications Will Also Expand Until RAM Is FullComment

Re: Website, CSF, and lots of attacks.
Regardless though, M.2 implemented on the PCI-E bus should be the fastest now I believe.
A 15,000 RPM hard drive is theoretically 50% faster than a 10,000 RPM hard drive. It's theoretically around 100% faster than a 7,200 RPM drive.-- Law of Expanding Memory: Applications Will Also Expand Until RAM Is FullComment

Re: Website, CSF, and lots of attacks.
You beat me to it. I didn't see your post. Sorry. They have SATA 15,000 RPM drives now? I'll check out the Raptor series.-- Law of Expanding Memory: Applications Will Also Expand Until RAM Is FullComment

Re: Website, CSF, and lots of attacks.
Diif, you know a lot about hard drives. Let's say I have a 15,000 RPM SATA 3.0 (6Gb/s) drive and a 7,200 RPM SATA 3.0 drive. The 15,000 RPM drive spins more than twice as fast, but isn't it still limited to the 6 Gb/s? I'd be able to retrieve files faster from the drive but the transfer rate would never go over the 6 Gb/s, right?-- Law of Expanding Memory: Applications Will Also Expand Until RAM Is FullComment

Re: Website, CSF, and lots of attacks.
in theory, a 15,000rpm harddrive could write data much faster than an SSD, but in most cases, not read as fast.
the interface is another matter, because you also have to look at the pc side.
a lot of these interfaces are already faster than the data can be dma'd into the ram.

Re: Website, CSF, and lots of attacks.
There aren't any 15000rpm SATA drives as far as I am aware.
A faster drive has a faster access time and IOPS input/output operations per second.
Whilst a drive might be connected to a SATA 3, that's not its read speed. Thats the theoretical max speed.Comment

Re: Website, CSF, and lots of attacks.
I'm having a hard time seeing how the speed of the drive affects overall transfer rates.-- Law of Expanding Memory: Applications Will Also Expand Until RAM Is FullComment

Re: Website, CSF, and lots of attacks.
Imagine a conveyor belt in an Amazon warehouse with two order pickers. One is a little faster on his feet than the other, the parcels still move along the conveyor at the same speed but there are more parcels with the faster picker.Comment
