IO Crest SY-PEX40039 2 Port SATA III PCIexpress x1 Card

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 MbpsAfter installation (SATA III) : Sequential Read and write speeds : 365.7 and 231.4 Mbps; Random Read and write speeds : 202.9 and 182.9 MbpsNot 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)

Using it for a couple of months now. I essentially bought it for my unRAID NAS. The onboard Marvell 88SE9230 has been buggy as hell with Linux Kernel giving me random RW errors. However, this card based on the ASM1061 is well compatible and working as intended.

Many many thanks to IO Crest & Amazon also, and also thanks to Customers' Rating. The Card successfully supported with my Intel DH61HO(H61 chip set) Motherboard, got it 1409₹. Working perfectly and Awesome speed.But the Card price is very unstable.

Working as expected. Thank you.

Does the Job.. working good

It just redirects internal sata bus . Does not serves the purpose of adding additional sata port.

Good work
