Plextor is still living 2012

post #1 of 16
Thread Starter 
Plextor M6S has came and there is nothing special about it except his price:
Tweaktown source:
Plextor's MSRP for the M6S products is almost laughable in 2014 for a mainstream SSD offering. Just days before the product launch, Plextor sent over the MSRP information. The 256GB model we reviewed today costs $249.99. That's higher than the Intel 730 enthusiast SSD (Newegg $229.99) and higher than the new Crucial M550 (Newegg $168.99) with an 8-channel controller that offers higher performance.

When are we going to get more performance out of SATA drives?

 

We want more 4k read and PCIe 3.0 x16 drives that fully saturate bandwidth!

How much i can see EVO that got 400mhz processor,100 more then 840 Pro, made broke through 40mb/s border.So i think what we need is to go in that direction=1ghz.

The 40MB/s 4k RR is due to the cache on the ssd. If you try larger testfile, the 4k RR will be lower thumb.gif

Then 840PRO is still faster

The EVO's 4K Random Read of 40MB/s is due to the cache on the SSD? What cache is that?

If you are referring to the RAPID mode caching in RAM, the 4K random read speed of 40MB/s is possible without RAPID enabled.

A performance comparison of any SSD with RAM caching to one without it is not valid, and Igor did NOT quote the 4K random read speed with RAPID enabled.

If you are referring to the DRAM cache used in both of these SSDs, it is identical in size across all available capacities.

Or are you referring to the buffer that TurboWrite uses in the EVO? The SLC-like buffer used to store data before it is permanently written to the main NAND? That buffer is only used for write purposes, and is not associated with read performance at all, and does nothing for 4K random read performance.

I assume you think data is read from the TurboWrite buffer during a benchmark test before it is written to TLC NAND? I don't find that information in any of Samsung's documents.

Samsung specs for the 840 EVO: 4KB Random Read (QD1): Max. 10,000 IOPS.

Samsung specs for the 840 Pro: 4KB Random Read (QD1): Max. 9,900 IOPS (256GB/512GB) Max. 9,800 IOPS (128GB)

The 840 EVO's slightly faster 4K random read performance, given the higher read latency of TLC NAND, is compensated for by the higher speed of the EVO's MEX controller.

Since the 840 Pro and 840 EVO use the same speed NAND chips (that transfer rate is not related to the NAND cells being programmed as MLC or TLC), it seems to be the controller itself that can be a bottleneck in performance, not just the NAND itself.

Try 12GB+ testfile in Anvil. Can it manage 40+ MB/s RR then?

My statement that EVO is faster because it has faster controller ,was only assumption.Problem is I don't have EVO,but I would also love to see Anvil benchmark with bigger test file then 1GB.What I am 100% sure is that PRO is not faster then EVO.

Faster with what tongue.gif

Looks like 840pro is better in many benchmarks smile.gif

For ASSSD benchmark, the Evo is the best. For real work, 840 PRO is the one biggrin.gif

The Pro is better for both. Don't forget that the Pro has RAPID support now. ;)
