Website, CSF, and lots of attacks.

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.

I thought Raptors were 10,000.
An SSD that is fully compatible with PCI-E 3.0 x 4 will be the fastest type with a theoretical speed of 32Gb/s (4GB/s).

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?

Re: Website, CSF, and lots of attacks.

it is faster, they have been around for many years - if you use scsi.
i have some.

there are also sata ones now - raptor series i think they are called.

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.

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?

The 15,000 RPM drives are really fast. I think they're more or less used in servers and usually come in SCSI form, but don't quote me on that. They're also expensive, or at least when I was looking at them they were.

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.

Re: Website, CSF, and lots of attacks.

...M.2 is a standard that can connect to PCI Express, SATA and USB...

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?

Re: Website, CSF, and lots of attacks.

Yes, that's what I was trying to say. There is the seek time and rotational latency to deal with in hard drives but not with SSDs.

They do 15,000rpm hard drives Keeney.

Re: Website, CSF, and lots of attacks.

If I'm understanding him correctly, I think what he means is:

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.

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.

Keeney123, I might be misreading what Diif is saying, but I don't think he's saying there's no difference in read speeds when it comes to comparing solid state hard drives with non-solid state hard drives. If I'm understanding him correctly, I think what he means is:

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.

Re: Website, CSF, and lots of attacks.

Things are identical with SSDs apart from not requiring to defrag the drive.
They have wear leveling built in to spread the wear across the cells, the data is spread across the drive. It makes no difference to read speed.

Gotcha, but it does matter, right? In the sense with a normal harddrive, you don't require the wear leveling, right? And although the user doesn't do it, if the data wasn't equally written across the drive like it is (with solid states), the drive would fail much quicker, wouldn't it?

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.

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.

Re: Website, CSF, and lots of attacks.

I would say there is a difference as with a HD it has to spin up the read head arm has to find where the data is on the disk. With a SSD it is a matter of an electronic address.

Re: Website, CSF, and lots of attacks.

As I remember it prevented things loading on the CD ROM and from being able to connect up to the USB that would load on all other widows platforms. It demanded I put in a HD password, a supervisory password and a user password to get full use of the system. Also, if one did not put in a HD password it froze the password. In order to unfreeze it one had to go through a bunch of steps and then one only had one shot at that. The 320 GB hard drive was broken up in 5 different partitions with 2 of those being over 100 GB. This slowed the Acer down. There was no option for Legacy. I really did not know at the time why would someone want to put a 2.5 TB drive in a netbook or for that matter a laptop as the look up time increases with Hard Drives. I guess now with the newer Solid State drives that is not as big a issue. The initial boot up time was faster, but once loaded it was slower. I wanted a small computer that had the quickness of a larger computer at half the price. The only reason I would ever need a computer over 250 GB would be for storage. Storage is not accessed as often so that drive could be off until I need it to come on line. In this way the computer would not have to consider a large drive in every operation.

We have, I have a computer with what you'd probably consider a lot of storage. One drive is 2.5TB, one drive is 3.0TB, and then I have a couple 2TB drives. Although it seems like a lot of space, believe it or not, I use it up fairly quick like.

With solid state, things are a bit different, right? For example, on a normal hard drive, you want data organized. You defrag the drive so the PC can access it quicker. With solid states, don't you want the data randomly spaced out among the sectors? So the cells don't wear down quick like? Try to make sure every cell or whatever they're called gets written to an equal number of times...maybe someone more knowledgeable with solid states could correct me if I'm wrong.

Re: Website, CSF, and lots of attacks.

Legacy BIOS caused some headaches with me for a little bit when I bought a 2.5TB drive. Took me a little to figure out why it wasn't working.

Just curious, what was your problem with the Acer and the UEFI BIOS?

Was it something with that secure boot?

Re: Website, CSF, and lots of attacks.

The install was not from a disk. I installed from a bootable hard drive. The hard drive has all the drivers and updates, user folders up til July 2015. I do have some third party stuff, but if I get annoyed with it I will just uninstall it. Thanks for the offer, but I find from experience this is the best way to reinstall the OS. Being that it sits on a self it is not exposed to the internet.
I do not believe my computer was infected because it operated just fine when not on the internet and I was able to stop the action from happening. I think the infection was out on the other side my router.

I think your PC had to be infected. This one customer I had, the symptoms only appeared when they were using google. It was a rootkit. I could run her PC normal like, albeit a little slow, and no pop ups or anything. Anytime I googled something though, about every 4 queries, I'd get redirected to adware. TDSKiller successfully detected the rootkit. If they were able to change your homepage, I'd think they had enough access to do other bad stuff.

When I was trying to find a weakness into a computer I was working on, on another computer, I used metasploit to create a shockwave video file with a craftily created small piece of code. Then I had metasploit setup a webserver. On the client machine, I just connected to the website. The small video played. It looked like a normal video, but when it played, I had the payload download a remote shell and set it up so I could get a command prompt remotely on that machine.

It wasn't anything illegal or anything like that. I was just messing around. I owned both PCs. But a normal user would have never of known they were ever infected. I could have even of hidden the remote shell process from the task manager so no one would have seen the remote shell running.

UEFI is evil, a payload can be uploaded into the bios.
just ask Lenovo victims/customers!
