PCIe SSDs?

What are the benefits of PCIe SSDs over SATA SSDs?

[Snickerzz]

Faster read/writes, they look better IMO, larger capacities (i think)

[Octavialicious]

Super fast, they are just very expensive

[Picky Peep]

No cabling :-D

What are the benefits of PCIe SSDs over SATA SSDs?

More bandwith -> higher speeds are possible

technically higher capacities, but we aren't at the limit yet. There is more space on 2.5'' drives for more chips.

Doesn't need a SATA power cable, cause PCI-e provides enough power

Doesn't need a SATA data cable, for obvious reasons

I have the Intel 750 series PCIe SSD, it is very fast. Latency is also faster.  The price is still fairly high, but worth it IMO.

Faster ect.Take longer to start due to them having to be initialised

[Lolucoca]

Really huge bandwith... They aren't bottlenecked by the Sata-bandwith-limit...

I'm pretty sure that's not true for NVME drives.  NVME seems to have a bright future for SSDs.

The m.2 ones on the cards have to I think.

Right now, today? Very little. The reason why lies with the programs you run rather than the drives themselves. Most programs load data synchronously one chunk at a time. This leads to a queue depth of 1 for most requests and makes access time the single most important factor in making an application go faster. PCIe SSDs are not significantly fast enough to justify their 3x markup over SATA drives today. In the future this will not be true.

 

If you happen to run an application you both want to run faster *and* know takes advantage of the performance via asynchronous reads or multiple read streams (like a software backup, database, or enterprise level application) then the PCIe SSD will offer massively increased throughput, in excess of 1GB/s. Yea, Gigabytes. It's a sad fact that where the technology and software are today, you need a queue depth of 4-8 to really start seeing any boost from NVMe drives and you need asynchronous reads to really see any benefit from PCIe larger bus bandwidth.
