When You really want that URL too large source:

6-Port SATA II 150 PCI Host Card w/Raid:


Yes that was your Google search, but then you got a link that only a total computer nerd could ever like an no one would ever think to actually type out:

Lets have a look (for convenience I will not actually make it into a hyperlink) here:

http://www.google.com/products/catalog?hl=en&sugexp=ldymls&xhr=t&q=6+port+sata+ii+150+pci+host+card+w+raid&cp=16&qe=NiBwb3J0IFNhdGEgSUkgMQ&qesig=7xz3NFyGt8qphP7XUkN5Rw&pkc=AFgZ2tmQbiGAUH_fhhsjUPKyEnTR433qC8vVJasV7MaKmYw99VlQmfr81BRTYwxuyMjLMc7JDVnYZlXs46Mr2tStMYe1RnBxrA&biw=1010&bih=540&bav=on.2,or.r_gc.r_pw.&um=1&ie=UTF-8&tbm=shop&cid=11328797192038667533&sa=X&ei=eQ3TTaL8FcH40gH6zrHnCw&sqi=2&ved=0CDkQ9AIwAQ&os=reviews

After writing and researching this entire article, I did go back to one of the corollary ideas and simply thought it would also be worthwhile to shorten the link:

I like bit.ly because its fairly easy to remember.

So the monster above becomes:

http://bit.ly/j8bqDp

Yes, that's the whole monster IP put into a little tiny package!



Yeah, so then you understand that something like that is barely tolerable to all but the most jaded Google Tech working his way up the ranks.

What was my original thought:

Gee, there is something cool about this 6-Port SATA II 150 PCI Host Card w/Raid its kind of expensive for a cheap card, and definitely too cheap and too slow for a good card. 


So, I figured before opening the box and maybe getting stuck with it for life, I thought what are other people saying:


The following one was the best:


"I can't get enough disk space. So even though I only want to add 2 disks I bought this card. Plus I too have gotten in the habit of using internal disks externally as removable backup. So even though I usually buy the cheapest I just decided to spend a little more . An extra $15! What a big spender I am this week. Works with Linux. Thanks to the other reviewers for mentioning this. See below. Yeah, it is sort of cheesy that they list this as a 6 port rather than noting is is 4 port with selectable 4 innies and 2 outies. And if I read the instructions right you can only redirect the connectors at the very corner of the card away from the card connector tabs to the external connectors. If you had something in your case blocking the center of the card and couldn't fit the cables there, you can't select those connectors to the external ports. I have over 32 partitions and volumes in this PC and the encrypted volumes are via Truecrypt so I have to figure partitions, volumes and devices. It was too much trouble so I just plugged everything..."

Apparently this review has run out of space, real cliff hanger eh?


So, we start off with genuine inquiry, and leave off with a little humor. Something for the geek and the kid in you. As far as my personal dilema is concerned, it really centers on the fact that you spend all this money to get the fatest processor, 8-Gigabytes of Ram but then you want an e-Sata port (why, who ever really knows) and at first you thought 4 internal Sata ports would be just fine, but now you want Raid 1 and extra Terabyte or so of extra back up and somehow you are thinking that you have to be able to copy one CD or DVD directly from another at high speed, and you already need 5 Sata ports!

Somehow when I read the motherboard specs and the HDD specs and read that these things were running at either 3- Gigabytes per second or 6 Gigabytes per second, so what could this 150 PCI card really do, so I wanted to know:

How fast is the 6-Port SATA II 150 PCI Host Card w/Raid in Gigabytes per second?:

"Great PCI SATA controller card
I originally used this card to add additional sata controllers for my PC, as my motherboard is older and only has four on board slots. It worked great, was easy to install and did exactly what I needed it to do with little to no effort. I ended up upgrading to Windows 7, only to find out that my mother board is not fully supported and my onboard sata controller did not have drivers for Windows 7 and gigabyte had no intentions of supporting Windows 7. I was able to move all of my hard drives over to this card and get back up and running, thanks to this purchase. It is now my primary sata controller and has been working for 8 months without one single issue. The eSata port is a great addition but it does use up an internal slot if you chose to use it. Still, the additional option is a great feature. If you are looking for a PCI SATA card - I would highly recommend this product. Price is great for the product that you get. Click BUY to read more Reviews
" Supports Sata up to 150MB/Sec "
Now when I was in the store I read that and showed it to the tech person, and asked; the new Sata drives are at 3 Gigabyte per second, and the newer one are at 6 Gigabytes per second. Now I keep hoping this package has some sort of typo, and then the store clerk says the 3 Gigabyte per second is the bandwidth?

Okay, I have done this before:

convert 150 MB to Gigabytes (in a Google Box)


I usually scroll down a few, from the results list and got:


http://www.t1shopper.com/tools/calculate/


Then after inputting 150mb and clicking Gigabytes I got:


 

A file size of 150 gigabytes can also be expressed as *

1,288,490,188,800 .......... bits
  161,061,273,600 .......... bytes
      157,286,400 .......... kilobytes
          153,600 .......... megabytes
              150 .......... gigabytes
                0.146484375  terabytes
                0.0001430511 petabytes
                0.0000001396 exabytes
                0.0000000001 zettabytes


Which is all well and good but lets face it, they are not answering the question I asked!

So I scroll down lower (BTW, never bother scrolling up, if the 4th guy on the google results is too busy selling you what ever they want to sell you, then chances are the 1st through the 3rd will no doubt have some similar purpose of their own) so here is what I wanted:



150mb = 0.1468 GB, which is kind of what I thought. 

Now if the box had said:

Supports Sata up to 1500MB/Sec "
Then I would have never bothered writing this article. After all:



It is simply not so uncommon in the rapidly developing computer technology race to back one or two quantum to save a few bucks. Yeah, thats right can you believe that in the days of dual core, quad core, and six core, and if not yet then as soon as I am dome writing this, 8 core processors, that people are still buying refurbished Pentium 4's. (Were those things even called that back then) what are they using socket 370 motherboards?

So, what is the spec on this Sata card, is 1/10 as slow as compared to the 1st generation Sata or is there simply a typo on the box. Or do I have to go back to computer Geek school and take 3 major pegs down for ever doubting the tech behind the counter who had the whole issue wrapped up when she told me the 3 Gigabytes and 6 Gigabytes per second was just the bandwidth?

Ah yes, but the whole bandwidth thing, thats a whole other story.

Until then, lets find out the straight talk, from the true techs!



SATA revision 1.0 (SATA 1.5 Gbit/s)

First-generation SATA interfaces, now known as SATA 1.5 Gbit/s, communicate at a rate of 1.5 Gbit/s. Taking 8b/10b encoding overhead into account, they have an actual uncoded transfer rate of 1.2 Gbit/s (150 MB/s). The theoretical burst throughput of SATA 1.5 Gbit/s is similar to that of PATA/133, but newer SATA devices offer enhancements such as NCQ, which improve performance in a multitasking environment.



So there you have it folks.The whole 1.5 Gigabyte thing was pure fiction after all. What kind of transfer ever happens at 1.5 GB per second?

Second generation SATA interfaces running at 3.0 Gbit/s are shipping in high volume as of 2010, and prevalent in all[citation needed] SATA disk drives and the majority of PC and server chipsets. With a native transfer rate of 3.0 Gbit/s, and taking 8b/10b encoding into account, the maximum uncoded transfer rate is 2.4 Gbit/s (300 MB/s). The theoretical burst throughput of SATA 3.0 Gbit/s is roughly double that of PATA/133.

So you see you had the answer all along, it really is just half as fast as the 2nd generation Sata devices.



All SATA data cables meeting the SATA spec are rated for 3.0 Gbit/s and will handle current mechanical drives without any loss of sustained and burst data transfer performance. However, high-performance flash drives are approaching SATA 3 Gbit/s transfer rate, and this is being addressed with the SATA 6 Gbit/s interoperability standard.

So if you really are not fully up to spec with 6 GigaByte per second motherboards and drives, then when you get going with your 150mb per second e-Sata ports, then you need this final comparison:

A USB 2.0 port (regular everyday USB) has speed up to:



USB 2.0, by now the most common interface around, boasts theoretical speeds of up to 480Mbps, surpassing the 400Mbps of USB's rival interface, Apple's FireWire (or iLink). Real-world speed tests, however, still hold that FireWire is the fastest interface, with actual speeds generally running double that of USB 2.0


So even if the USB port lived up to its boasted reputation, it would at best be less than half as fast as your as your now two generations old " 6 port sata ii 150 pci host card w raid"


What's all this obsession with speed, I imagine a tech newbie might ask? My answer goes like this, be sure to tell your boss the safest way to back up your entire system is to clone your HDD, before any major upgrade, when he has the technical guy from the software company on the clock at like $180/hr, waiting to do a major software upgrade.

 This might be a good time to try to monetize this blog. 


Have a safe night, and don't forget to clone your HDD!
