These cables are not available separately for the time being and we do not have any information if they will be available on the market any time soon. Please bear in mind that the Intel® SSD Data Center Family such as the Intel® SSD DC P3500, Intel® SSD DC P3600, Intel® SSD DC P3700 were designed to work with HBA ( Host Bus Adapter). The cable that comes with the 750 would actually work with the SFF-8639 model of the Intel® SSD DC P3500, Intel® SSD DC P3600, Intel® SSD DC P3700.
first one is on market
seller answer me via e-mail .. "sff-8639 cable will be available in a few weeks"
so with that adapter they used p3600 - http://ecx.images-amazon.com/images/I/610WhHOq5lL._SL1010_.jpg
and got only ~500mb/s speed - http://ecx.images-amazon.com/images/I/711A78uw4FL._SL1001_.jpg
so that doesn't work good at all
Please keep in mind that Intel does not endorse or recommend the use of unofficial 3rd party adapters.
The Intel® DC SSD P3700/ P3600 / P3500 and Intel® SSD 750 Series are available in 2.5" and Add-in-Card HHHL form factors. The AiC version can be connected directly to a PCIe Gen3 x4 slot and does not require an adapter.
The 2.5 in DC P3xxx drives do not include the U.2 cable since they were originally intended for enterprise usage. Now that some motherboard manufacturers support the NVMe 2.5" SFF-8639 drives using a compatible adapter and cable, we are working to make the supported U.2 cable available, however, we do not have a specific date for this yet.
if this adapter use pci-e 3.0 with 4 lanes... total bandwith must be around 4GB/s ..it looks like just using sata 3.0 interface .. i think pci-e lanes doesnt work at all or passive at the moment.. but i ordered this item before these photos added..when i receive my item i ll give u my results.. i have p3700 ssd..
Hello eczanet, I would like to add some information regarding link bandwidth.
Sata 3.0 link performance is 4.8 Gb/s (Gigabits per second), and the one for PCIe 3 x4 is around 4 GB/s (Gigabytes per second). Since each Byte contains 8 bits, 1 Gigabyte is equal to 8 Gigabits. So there is a considerable difference between SATA 3.0 and PCIe 3.0 x4.
The SATA III (revision 3) interface runs at 6.0Gb/s, with a maximum uncoded transfer rate of 4.8 Gbit/s (600 MB/s). The PCIe 3.0 performance is 7.877 Gb/s (984.6 MB/s) per lane, so, the theoretical maximum for PCIe 3.0 x4 is 31.508 Gb/s (3.9384 GB/s)
You can review the following links for more information:
As you can see in the Specifications for Intel® SSD's, PCIe NVMe drives' performance exceeds the maximum possible with SATA 3.0, and high end models like the Intel® SSD DC P3700 Series actually use a good portion of the PCIe 3.0 x4 bandwidth.
Hello Jonathan, Many thanks for all your help here.
You've probably heard that a picture is worth a thousand words.
Lots of Enthusiasts are stumbling on the differences between
the 8b/10b "legacy frame" and the 128b/130b "jumbo frame"
(my choice of nomenclature / not necessarily industry standard).
It would help a lot of you could prepare a simple graphic
comparing the two frame types. We did that here
in our presentation to the Storage Developer Conference:
(see Page 7).
I believe PC users generally understand that
a byte requires 8 bits. It's the START and STOP bits that
are confusing people. A more detailed graphic could
also illustrate the 128b/132b "jumbo frame" adopted
in the USB 3.1 specification. A good well designed graphic
will help PC users understand how PCIe 4.0 will double
raw bandwidth, using the same 128b/130b jumbo frame.
Keep up the good work!
This request is still under consideration, however, the cable is not available separately from Intel at this time. Currently, we are not able to confirm if this will change in the future.
The U.2 interface is meant to be used with the Intel® SSD 750 Series (consumer SSD's). Even though it may be possible to find 3rd party cables on the market, these are not tested/validated as a supported configuration for Intel NVMe* Data Center SSD's.
