1 out of 5 eggsdoesn't work with asus p7p55 mb

Pros: it works but at speeds lower than what i get when the sata 3 ssd plugged into sata 2 port. oh yeah easy to install card and drivers and no BSOD's

Cons: computer is up to date with all win 7 and bios updates. after installing card and drivers got seq read/write of about 200/180MB/sec. with sata 2 port on mb got seq read/write of about 280/260MB/sec. tried different pcie slot - same results. downloaded latest drivers from Syba website - same results. tried other port on card - same results.
always checked device manager to see if any issues with drivers - none.

Other Thoughts: Could be compatability issue with mb though Asus says they are PCIE 2 X1. glad I didn't pay more - not worth returning.

5 out of 5 eggsClarify PCI-e Versions

Pros: This SYBA card is designed for PCI-e revision 2.0 / x1 slot.

See Other Thoughts below for explanation.

Cons: none at the price.

Other Thoughts: You already know about USB ports and their speeds. We had USB 1.1 ports (slow), then USB 2.0 (faster), and now USB 3.0 (even faster).

PCI-e is sort of like that. We had PCI-e 1.0 (fast compared to old PCI which it replaces), then PCI-e rev. 2.0 (faster), and now PCI-e rev. 3.0 (fastest).

But there's more. Each PCI-e revision has several different size slots. The bigger the slot the more bandwidth/speed it offers.

An x1 slot is the really short / small slot and has 1 "lane" of bandwidth offering around 380MB/sec. max. Read or Write speed.

An x4 slot is slightly longer and has 4 lanes of bandwidth allowing , for example, an SSD to reach over 500MB/sec. Read speed (Write speed may be slower due to overhead in the system).

An x8 slot has 8 lanes of bandwidth. This type of slot is rarely seen on motherboards.

An x16 slot has (up to) 16 lanes of bandwidth. Some motherboards have 2 or more x16 slots. Usually one slot has full bandwidth and the extra slots are limited to x8 or x4 bandwidth.

So, an add-on card like this particular SYBA card is designed with one lane of bandwidth and fits in an x1 slot. It will also fit in an x4 slot or x16 slot but don't expect faster speed because the card itself is x1 speed. If you connect an SSD to this card it can achieve around 380MB/sec. compared to around 280MB/sec. on a motherboard SATA II port. A nice improvement at very low cost!

The next grade up in SYBA controller cards is x2 bandwidth (for example SD-PEX40054). Those cards fit in an x4 slot BECAUSE THERE ARE NO x2 SLOTS ON YOUR MOTHERBOARD. The cards are x2 speed.

Finally, if your motherboard is really old it may have PCI-e rev. 1.0. These add-on cards will work OK in rev. 1.0, but the available bandwidth and speed are CUT IN HALF.

Hope this clarifies the PCI-e thing a little bit for everone !

4 out of 5 eggsA sideways step on my older Gigabyte motherboard ...

Pros: The card was easy to install in my standard-sized case. I didn't have to change any settings in drive boot order in the BIOS, it just booted immediately with my 256 GB Samsung 840 EVO. Windows 7 x64 automatically found and installed the drivers.

Cons: On my Gigabyte EP43T-UD3L, the printed manual says the motherboard is PCIE 2.0 compliant, but the online manual says the PCIE slots are all 1x. Double check between the manual and the web site before you buy. :) That having been said, it's still a slight speed bump in regards to throughput, but routing data through the PCI bus seems to introduce a bit of lag. It seems like a wash to me. Still, this is a decent, inexpensive card.

Other Thoughts: I gave this four stars even thought it didn't quite work out the way I expected it to. This is a great value card, and I can still use it to expand the number of SATA ports on my system (I was running out.) Four stars from me!

5 out of 5 eggsWorks as intended

Pros: Easy to install. Worked immediately with on a system that was already set up earlier.
Gives a significant speed improvement to my SSD compared to SATA II.

Cons: the "press any key to abort" step during boot should be shorter.

4 out of 5 eggsBootable

Pros: Bootable ACHI SATA. Exactly what I needed.

Cons: Only two ports? I mean, it was <$30 So I got what I paid for.

4 out of 5 eggs

Pros: Easy to install and the drives attached to it was immediately detected in the bios. Windows OS"s automatically installed drivers with no fuss. Its bootable and allows pretty good speeds. Loading windows 10 on a ssd was only a few seconds slower then an on board sata III port. Great considering the card is plugged into a pcie 1.1 slot.

Cons: While drives are visable in the bios the controller doesn't appear to be. Which means i can't changer any functionality of the ports. The drives don't appear with a sata port number. Not dropping an egg cause this is the first controller I had to buy and i don't know if this is normal.

Other Thoughts: I have three ssd's, two 2tb storage drives and a dvd drive. One of my sata ports malfunctioned and causes bsod rendering system unbootable until drive is disconnected from it. Didn't matter if it was a storage drive or if the port was disabled in the bios. Having a drive connected was enough. This left me one port short so i'm using it for my dvd drive. I did test with an ssd and only saw a relatively minor increase in boot time. Also worth mentioning when I first power on the cards info displays over the bios boot screen. It competely blocks it. However it still responds to key commands (F12, delete...etc) even though the options aren't displayed anymore. Just pointing it out in case anyone worries that their bios functions are gone with the card connected not so. Also the card was quickly picked up and drivers auto installed by windows 7, 8.1u1 & 10 preview. The install disc shouldn't be necessary. Perhaps on older versions maybe. Haven't tried it on XP or Vista so can't say. Overall if you have a bad port you need replaced (like me) or just an unnecessary about of drives (also like me) this card is an inexpensive way to get more capacity at solid performance.

3 out of 5 eggsbad card

Pros: It can add SATA iii ports to your motherboard. It is very small. It is cheap when it is on sale.

Cons: It couldn't recoginze my Toshiba Q Series HDTS212XZSTA 128GB while my motherboard could recognize. I inserted 2 drives into 2 ports at the same time. Only one drive showed up. I have tried many methods to make my Toshiba Q 128GB SSD work, but no hope.

5 out of 5 eggsSeems like a great SATA Card

Pros: I'm hoping this SATA card will work with my OpenSuse 64-bit Linux works, won't be running on any other OS.
My review is therefore centered around Linux. Other reviews have said this works on Linux Unbutu and others.

Cons: 0

Other Thoughts: Onboard SATA2- Read/Write average: 266/235 MB/s - Good
Add-On budget SATA 3- Read/Write average: 371/364 MB/s - Good

It uses the AsMedia 1061 chip which has been around for a while.- Good very stable
It DOES support TRIM commands through Windows and Linux - Good

It has maximum read speeds in the 500 MB/s range - Good.

Great! Very respectable! This $17 card provided a nearly 50% increase in read/write performance over SATA 2, good price.

1 out of 5 eggsNice Package

Pros: None

Cons: Doesn't work with the Intel mobo I bought it for.

Other Thoughts: Not heavy enough for a paper weight and cost too much to ship it back so "file 13 here I come."

3 out of 5 eggsIt's a roll of the dice...

Pros: When it works, it works well. Easy to install, and is also very lightweight. I have a Blu-Ray burner w/3D and a DVD burner, both connected to it, and have no trouble with either drive. When it works, the throughput is just as smooth and vast as can be, at least to me it seems that way, even when playing a Blu-Ray disc in 3D from my PC to my 3D HDTV.

Cons: There are no cable-locking notches to hold the SATA cables in place, which allows for them to come loose very easily. The card, somehow, also tends to slowly creep out of the PCI-E slot just enough to start causing a lot of issues with the motherboard (system freezing, disappearing drives, etc.), and you don't realize it until you get down in close proximity of it (it's such a slight creeping that it can easily go unnoticed for months, until you start having issues, for me it usually takes a few weeks). This happens much more easily in X8 and X16 slots, but happens in X4 and X1 slots as well.

Other Thoughts: I'm considering RMAing the thing, but am unsure simply because if they give me another one of the same model, it's still going to creep like this one and not have the cable-locking notches either, thus providing the same issues. Sadly, I can't get a refund from Newegg by now, so I'll see what SYBA says, as soon as I get my affairs in order and figure some things out. This card aggravates me to no end, and the fixes for these issues are so extremely easy to do that I honestly have no idea how they haven't been done by now. I know it's not an expensive card, but still there's no logical reason it should be made so cheaply and such important details be left out.

Manufacturer Response:
