Need advice on M.2 with PCIe
Goal: the get meaningful speed increase from SATA 250G Samsung EVO
to some m.2 500G
CPU i7-2600 , 1155
MB: ASUS P8B75-M with no M.2. There are
1 x PCIe 3.0/2.0 x16
1 x PCIe 2.0 x4
2 x PCI
I am thinking about:
StarTech.com M.2 Adapter – x4 PCIe 3.0 NVMe
https://www.amazon.ca/StarTech-com-M-2- ... B01FU9JS94
and 207$ WD-Blue (m.2, 2280 whatever it means), can not find speed
https://www.amazon.ca/WD-BLUE-CSSD-M-2- ... B073SBX6TY
or 250$ Plexator, NVMe 2,000/1,400 MB/s
https://www.amazon.ca/Plextor-PX-512M8P ... 01JCXXYMQ/
or 283$ Samsung ,m.2, 2280 Up to 540MB/s and 520MB ??? really ????
https://www.amazon.ca/Samsung-850-EVO-I ... 00TGIW1XG/
Q1: what is the difference between m.2 2880 and M.2 PCIe as in the link:
https://www.wdc.com/products/internal-s ... DS512G1X0C
Q2: m.2, 2280 often reported as having 540 read/write. But it is
ordinary speed of SATA-III-SSD. Where is 2.5/1.5G speed?
Q3: is selected adapter good for given MB? Adapter is PCIe3x4, MB has PCIe3x16, it is OK?
Also: Is oldish i7-2600 good for targeted high-speed?
Q4: is "NVMe" necessary to get high speed > 540M/s ? Plexator is reported as NVMe but Samsung -- not.
Q5: any related advises are welcome. another adapter? another ssd?
Thanks in advance.
