Meine SSD erreicht nicht ihre Geschwindigkeit?
Moin,
Ich habe mir jetzt eine neue SSD (Samsung 870 Evo) geholt nun habe ich sie eingebaut und den rechner gestartet, dann wollte ich direkt mal testen ob sie auch die genannten übertragungsgeschwindigkeiten hat. Natürlich geht nichts im Leben Fehlerfrei und so erreicht sie nur im Lesen 200Mb/s oder so, sie sollte aber um die 500 erreichen. Also mein Mainboard und mein Bios ist schon ziemlich alt (MS-7728) Bios habe ich auch nicht geupdatet man findet sowieso nicht das richtige update. Ich habe mir extra ein Sata zu USB 3.0 adapter geholt damit ich meine neue Festplatte daran machen kann um bis zu 500 Mb/s zu erreichen weil mein SATA 3 port ja auch zu alt ist und es nur bis zu 300Mb/s übertragen kann. Ich hätte mir auch eine Steckkarte für PCIe holen können und daran die Festplatte machen aber da möchte ich noch eine WLAN Steckarte ran machen. Jetzt ist es aber so das die Festplatte nur 200Mb/s erreicht was mich wundert weil eigentlich mein Mainboard ein Usb 3.0 port hat und der schneller übertragen müsste, es ist aber nicht so ich verstehe es nicht. Ich habe die Festplatte schon Formatiert, und verbessert, trotzdem kam nicht mehr als 215Mb/s an. Treiber Updates habe ich schon von USB Controller sämtliche gemacht. UASP wird mir auch angezeigt das ich das habe und zu info ich benutze WIN 10. Nun habe ich gegoogelt und gefunden das es eine Einstellung XHCI gibt im Bios, dann habe ich direkt nachgeschaut aber nichts gefunden, später habe ich gelesen das es nicht jedes Bios hat. Aber was soll ich jetzt machen? Das Bios upgraden ? Das würde ich eigentlich ungern tuen und ich finde sowieso nicht die richtigen Datein dafür. Ich habe schon so viel versucht aber es hilft nichts. Kann mir bitte jemand tipps geben darüber würde ich mich sehr freuen. Kann es auch sein das das Mainboard selbst ein grenze hat zum Datenaustausch? Weil es ist ja schon alt aber warum hat es dann Usb 3.0? Ich werde mal meine Festplatte an Usb 2.0 anzschließen und schauen wie schnell sie dann ist. Ich weiß nicht ob das wirklich wichtig da ist aber mein RAM ist alt ddr3, wird nur 10Gb erkannt, hat dual, und so um die 1300Mhz oder so weiß nicht genau. Aber es hat ja nichts wirklich damit zu tun wie schnell meine SSD Daten Liest und Schreibt
Freue mich auf Antworten

Hello

This is an intel base 1155 H61 motherboard.
On this motherboard there is no SATA III support, but only SATA II with up to 300MB/s, from which the SATA protocol Overhead has to be deducted. If the SSD runs at one of the SATA II port with 200MB/s, then it’s completely OK. That’s all I can do.
On the board there are USB 2.0 and 3.0 support. Data rates up to 480Mbit/s are possible via USB 2.0, or 60MB/s, from which the USB protocol overhead has to be deducted, so that a useful data rate of 40MB/s remains and USB 3.0 would allow up to 5000Mb/s, i.e. up to about 400MB/s for user data. Even with an SATA III -> USB 3.0 adapter, a SATA III SSD connected to a USB 2.0 port can only run at a maximum of 40MB/s and on a USB 3.0 port with up to 400MB/s.
The USB 3.0 ports are internally located on your motherboard and are not accessible from the outside if you do not open the case, except it has been connected to a USB 3.0 front panel. Then USB 3.0 is available to the USB case sockets.
These are the two USB 3.0 ports.
The USB 3.0 support has been realized via an extra chip because the intel H61 chip has not yet mastered a USB 3.0. The ASMedia ASM1042 PCIe to USB 3 Host Controller is connected via PCIe with a PCIe Lane, which is a PCIe x1 connection.
http://images.100y.com.tw/pdf_file/35-Asmedia-ASM1042A.pdf
Since only PCIe 2.0 support is available on your motherboard, only a maximum data transfer rate of about 250MB/s can be achieved via a PCIe 2.0 x1 connection. A USB 3.0 host controller connected via PCIe 2.0 x1 can not change anything like the ASM 1042 chip and therefore the SSD itself runs on a USB 3.0 port of your motherboard only with 200 to 250MB/s.
This would also not help, as there is no PCIe 3.0 support on your H61 motherboard, even with a socket 1155 series 3000 processor and if you use a PCIe x1 -> SATA controller card, then only PCIe 2.0 x1 speed would be possible, which corresponds to about 250MB/s for user data.
The 500MB/s data rate that could reach your SATA SSD will not be able to reach it on the H61 motherboard, either via SATA, USB or via PCIe.
You should also take care of and not confuse Mb/s with MB/s.
Byte and bit are not the same, but 1 byte corresponds to 8 bits.

This is not really the case 🙂
and my only option is to buy a new motherboard now? 🙁
you can switch off or throttle the USB protocol overhead somehow, I would not buy a new motherboard because then I need to replace all components directly and that will be expensive. Does it somehow help to update the bios so I hopefully activate xhci hand off so that the UASP works? I don’t know so much about it.
So really thank you again, you helped me a lot more and told me a lot of information I didn’t know before. I also sometimes wondered why the B at MB and Mb is sometimes small or big, now I know. Kiss. Now I also know why my hard drive is running a bit slower than with sata, despite the same transferatte. But can’t I update the Intel H61Chip? and maybe it gets USB 3.0 or is it the hardware of the chip?
The H61 chip is what is still available from the motherboard chipset on the board itself. This is the Southbridge chip of a motherboard, which is a PCIe I/O controller hub. The Northbridge has now completely migrated to the processor.
However, the upgrade of a motherboard chipset is not provided. You won’t be able to upgrade the H61 chip. For this, you would have to replace the motherboard against one with an intel series 70 chipset. These would be intel bases 1155 motherboards with a B75, H77, Q75, Q77, Z75, Z77 chipset. Your Socket 1155 processor should also work on it, no matter what you have.
SATA III (6GBit/s) support is available on base 1155 motherboards with a series of 70 chipsets and USB 3.0 support. PCIe 3.0 support is also available in the first PCIe x16 slot when a socket 1155 series 3000 processor (Ivy Bridge) is used. With a socket 1155 series 2000 processor (Sandy Bridge), the first PCIe x16 slot with PCIe 2.0 support reaches the end. This is because the first PCIe x16 slot is connected directly to the processor. The remaining slots are connected to the motherboard Sothbridge chip and in principle only offer PCIe 2.0 support.
Okay many thanks, you helped me very much!
With USB3 you are already relatively close to the 560MB/s maximum speed.
But now comes the protocol overhead from USB and Sata. So I would expect a speed of about 2.5Gbit/s at USB3 which would be 312MB/s.
Moreover, it does not have to mean that each USB3 port creates the full data rate in the long term, which depends on the connection from it.
In other words, I would not expect the full data rate of the disk via USB 3 and you would probably have to measure it with Sata.
What is the Overhead protocol? What’s he doing?
Well, the 5GBit at USB is only the pure data speed. You have to take all the control commands away from USB.
Then, this USB interface also sends a protocol to address the hard disks, which is again additional data that are not useful data for you.
These necessary data, which are not directly usable for you, are the protocol overhead.
He’ll be the bigger you nest.
Intel FCLGA 1155 socket with H61 chipset. There is PCIe 3.0 only with a 3rd. Gen. Intel Core CPU, and even DAS has not been self-evident depending on the board and switch at Intel’s H61 PCH.
However, only 200 MByte/s would be a bit leaner even on SATA III / 6 GBit/s or PCIe 2.0 @ 1 Lane in the peak. 450 to 550 GByte/s would have, depending on the interface, under optimal operating conditions of the SSD Peak can jump out.
Note, however, that with benchmarks such as “Crystal-Diskmark” the best possible read/write peak marks can only be ticked out from an SSD under very specific conditions.
SATA III / 6 GBit/s creates approximately 550 MByte/s in the user data traffic in practice minus the coding overhead in the peak.
