/O Crest 4 Port SATA III PCI-e 2.0 x1 Controller Card Marvell 9215 Non-Raid with Low Profile Bracket SI-PEX40064

Ok, just so that everyone is clear, this card does NOT support RAID or HyperDuo!! What this card does, and does very well, is to add an additional four internal SATA ports to your system via the PCIe slot, which is perfect if you have an older motherboard, like mine, and need additional SATA ports, but don't have the money to buy a new board, or simply have no reason to change your existing motherboard. The card come supplied with two SATA cables, which by my guess are 45cm in length, the driver CD and a low profile backing plate. It turned out I didn't need the driver CD, because after inserting the card, connecting my drives and powering the system back up again, Windows installed the needed drivers perfectly and my attached drives appeared straight away. If you're after a quick and affordable solution to add additional SATA ports to your system, this is it. But once again, this card does NOT do RAID or HyperDuo...

If you have to keep your somewhat older PC with older SATA protocol, get this and change your drive with an SSD. You will be amazed. Even if you use a mechanical HDD you will get an instant double speed (6Gbps compared to 3Gbps of the older protocol). What is worth noticing is that it can be used with the standard windows drivers, meaning you can clone your older driver straight to this one and it will boot right away. Of course you can install the specific drivers which are compatible with all windows up to 8.1 64bit so far. Some warning, this is a special type of SATA controller -that is why is somewhat expensive. It uses 2 PCI-e channels attaching 2 disks per channel (it has 4 ports). The hyperDuo function allows the combination of SSD and HDD to act like one super fast, high capacity drive. The SSD stores the most used stuff while the rest of the data are piped to the HDD which in general has a bigger capacity. It also offers disk encryption at hardware lever (I did not test this). If you do not need these functions e.g. you have one only drive, then a simpler (i.e. cheaper) solution will also give you the double transfer speed.

Running Linux Mint 17, 16GB DDR2 Ram Core2 Quad. I Used this to replace a SATA 2 card which I had bought 3 years ago. I plugged it in, connected my drives, leaving the boot drive and BD Burner on the motherboard and switched on. It just worked. No messages, no installing drivers, no anything. Just the 4 x 3T drives sitting there ready to be accessed. I tried a copying 1TB data from one drive to another. A mixture of large >10GB files and small files 20KB-100MB. A total of 4000+ files. All went accros in 5 to 6 minutes as opposed to the 20+ minutes with the old card. Not the fastest of SATA 3 cards, but the speed/cost ratio means I give it 4 stars. But only because I've just been using it for 2 months and so have no idea about long term reliability.

Running with an ASUS motherboard with all 6 SATA ports taken up. SATA - Serial AT Attachment is used to connect disk, optical and Solid State Drives to your motherboard for the uninitiated. I wanted to install a second Solid State Drive (SSD), but had no spare SATA port to connect it to. I had spare PCi-E (Personal Computer Interface - Express, oh these acronyms get so annoying!) slots so this card provided the interface for another 2 SATA ports. Installation took less than 5 minutes and perfect results (using Windows 7 64 bit). Usefully the box also contained 2x SATA leads which weren't advertised as included - many thanks. Good product and does exactly what it said it would without fuss or drama. Connects at max 6Gb per second.

Plugged into a free PCIe slot, started the computer, and Windows picked this up and installed it immediately. Shut down and attached a SSD drive, and this was immediately recognised and running at its full speed (although it is only an older 3G version: I am still awaiting delivery of my shiny new 6G drive). I suspect that those who have had trouble with this have installed the card and attached a drive together. My advice is to install and boot up with the card alone and let Windows find it, then shut down and attach the drive separately. My system is running windows 7 pro x64. I did not find any noticeable increase in boot times after installation. It was also a pleasant surprise to find that the box includes two bundled SATA cables. Looking back at the listing, these are show on some of the pictures, although are not highlighted in the text.

I bought this to solve the problem of not enough SATA III ports on a new motherboard. My old board had eight ports, all of which were in use. The new one only has four ports plus a riser board for two M2 SSDs. I have a high end PC, but I refuse to pay the exhorbitant prices for M2 SSDs. I need ports for an SSD, four 1TB HDDs, a blu-ray drive and will soon be adding two more 4TB HDDs. Yes I really do need all this storage and have no intention of trusting my precious data to cloud storage or it's vendors. My data is my data! The answer to my port problem is this wonderful Syba 4 Port PCI-e x1 Controller Card. It's easy to install and does the job perfectly. Full marks to the vendor and manufacturer. Sorry for my rambling rant ;¬)

10 Crest SY-PEX40039 2 port SATA III is a very good card. I got it today afternoon and installed it on my PCIe 2 slot (as suggested by the product manufacturer) and connected my boot ssd and set it as drive 1 (boot drive) through bios. I was in doubt, but it booted instantly. My motherboard supported only SATA II interface, which was bottleneck for my ssd and I could solve the problem with this card only at an expense of Rs. 1900/-. My statisticsare : Before installation (SATA II) : Sequential Read and write speeds : 257.6 and 204 Mbps; Random Read and write speeds : 160.9 and 63.9 Mbps After installation (SATA III) : Sequential Read and write speeds : 365.7 and 231.4 Mbps; Random Read and write speeds : 202.9 and 182.9 Mbps Not a jump indeed, but a formidable boost beyond doubt. I highly recommend this card for the SATA II motherboards for an easy and inexpensive upgradation (need not to change the motherboard)

No hace maravillas, pero incrementa la velocidad de transmisión de datos de discos sata III a placas con sata II. Para que funcione medianamente bien es necesario que el puerto donde se conecte sea, al menos, PCI Express revisión 2. He hecho test y a más velocidad del puerto PCI Express, algo más rápido es la transmisión de datos (tampoco muchísimo mas). Tiene que quedar claro que no va a llegar a la misma velocidad que una placa sata III, pero por muy poco dinero, puedes alargar la vida de ese ordenador al que tanto cariño le tienes. Tiene dos conectores internos sata II y se puede conectar en un Puerto PCI Express x1. Lo he probado en placas Gigabyte y HP y no me han dado problemas, aunque en equipos workstation de HP, no se por qué, no funcionaba en los PCI Express x4 y lo tuve que pinchar en el x1. En otros equipos lo he puesto en x16 que tenía libre. Ideal para conectar discos SSD. Me ha dado problemas con Windows 10 (va lentísimo, mucho más lento que usando los puertos sata II de la propia placa. En Window 7 funciona perfectamente.). La mayoría de las placas lo autodetecta sin problemas y no necesitas del CD de instalación que se incluye en la caja. Desventajas: No se puede hacer Raid sobre los discos montados en este adaptador.

Edited my previous review. I thought it has given up on me after 2 years. Relocated the card away from GPU and working great. Used it for boot SSD but now running 2 3TB drives on it. No frills no hassles plug n play. Default windows generic drivers perform best.

Je souhaitais une carte contrôleur pour avoir 4 ports SATA III supplémentaires afin de brancher un HDD de 5To, un HDD de 10To, le dock 2.5" externe de mon boitier ainsi que le port eSATA en façade. J'ai reçu la carte hier (si il y a un soucis j'éditerai ce commentaire). Je l'ai branché sur un PCI-E x1 et elle a fonctionné directement sur mon PC sous Windows 10 sans rien faire de particulier. Le pilote s'est installé de lui même et les disques durs ont été détecté directement. J'ai tenté un test sous CrystalDiskMark et les disques n'ont pas perdu en débit. Mon transfert de 1,3To s'est passé sans soucis autour de 130-200Mo/s comme d'habitude. Je n'ai constaté aucune déconnection jusqu'à présent contrairement à ce que j'ai pu lire sur d'autres commentaires. La carte est livrée avec 2 câbles SATA rouges classiques de 40cm et un adaptateur pour les petits boitiers. Livraison rapide en 3 jours. Le seul point négatif est que cette carte est en PCI-E x1 2.0 donc debits limités à 500Mo/s. Sachant qu'un disque dur, dans des conditions idéales, peut atteindre 200Mo/s en lecture/écriture, cette carte pourra éventuellement brider 3 ou 4 HDD transférant des données en même temps. Mais bon, pour le prix de cette carte, c'est vraiment chipoter. :D Important pour les étourdis : Cette carte ne supporte pas le RAID. A noter qu'elle est garantie 3 ans. Bref aucun regret, je recommande.

Il controller funziona perfettamente e ha fatto si che il disco ssd sata venga riconosciuto come ahci anche se la mia vecchia scheda madre non supportava quella modalità. In sostanza il controller fa si che la scheda madre, pur contrassegnadolo come ide, si interfacci con l'ssd sata con modalità ahci e velocità di trasferimento nominale sata 3. È aumentata la velocità di lettura scrittura su ssd (che è passata da 1.500, quando il disco era attaccato direttamente alla porta sata della scheda madre, a 2.000) ma soprattuto sono stato attivati la modalità ahci e trim, vantaggiosi per l'ssd anche per evitarne il deterioramento. Windows 10 riconosce automaticamente il controller e installa il driver storahci che gestisce il disco meglio del driver marvell (che si trova nel cd all'interno della scatola). Per far si che la scheda madre faccia il boot bisogna ricordarsi di indicare l'ssd come primo dei dischi collegati. La cosa non è automatica perché la scheda madre vorrebbe mettere per primi gli altri dischi (sata meccanici). Invece bisogna specificare che si vuole fare il boot dal disco ide. Il controller, nell'interfacciarsi con la vecchia scheda madre, indica il disco come ide, ma in realtà, dopo il boot, il disco viene riconosciuto correttamente come sata 3, con il driver storahci e la fubzione trim attivati. Chiaramente la scheda pcie x1 a cui è collegato il controller, ha i suoi limiti, quindi il disco ssd non viaggierà comunque al massimo delle sue possibilità. Però, come ho già detto, i protocolli di gestione adesso sono quelli ahci (che prima di fare il collegamento che ho descritto non potevo attivare perché non previsti dalla motherboard). Consiglio di collegare altri dischi(meccanici) alle porte sata della scheda madre e non al controller, in modo che tutta la banda della scheda pcie x1 resti dedicata al controller e al disco ssd di boot (su cui ho installato tutti i programmi e il sistema operativo). Ho finito con le espansioni possibili, non mi resta in futuro che cambiare scheda madre (e quindi ram e processore). Però il mio vecchio pc (con 8 giga di ram ddr2 e processore phenom) , truccato com'è regge ancora botta e windows 10 si avvia in modo istantaneo
