HDTach
HD Tach will test the sequential read, random access and interface burst speeds of your attached storage device (hard drive, flash drive, removable drive, etc). All drive technologies such as SCSI, IDE/ATA, 1394, USB, SATA and RAID are supported. Test results from HD Tach can be used to confirm manufacturer specs, analyze your system for proper performance, and compare your performance with others. HD Tach is very easy to use, quick, and presents data in easy to read graphs, including the ability to compare two storage devices on screen at the same time for easy analysis.
Bursts are provided only for your review. SSD's don't cache the same way HDD's do (in many cases they don't cache reads at all), so burst testing typically results in figures that are lower than the sequential throughput figures, regardless of controller used.
HDTach feeds the tested drive a continuous string of small sequential requests. This is a single threaded operation, which means the SSD doesn't get to see what's coming next. The lower the QD=1 latency of the controller pipeline, the better the numbers we see from this test. It doesn't equate to real-world maximum throughput, but it does mean something for analysis, which is why we include these results. Here we can see how the various controllers handle this type of workload, with slight variances in the way those different controllers handle QD=1 sequential IO streams.

Tempted I am on upgrading my 4 year old c300 256 gig sata 6, to these in raid 0 or 2 evos 500 gig models. I feel these are more about reliability then performance.
2 cheap ssds in raid 0 or upcoming sata express ssds.

Not sure that I see much wow
Not sure that I see much wow factor out of this one. All presented models has more or less the same performance.
Only difference with the newer model is probably the reduced cost (still minimal) which is starting to show for all SSD on the market. And the actual die has reduced in size.
For a budget, the 128GB would be my pick. An additional HDD would support additional greater storage for the same cost. All my HDD has outlast all my flash devices.
As for the controller, ain’t the Marvell the same as the Sandforce? My mother board doesn’t like Sandforce controllers.

The failed flash devices were
The failed flash devices were not SSD. However, though they were primarily USB flash devices, the concept is the same. You could blame the poor components, but consumers often don’t have control over that aspect.
One of the devices were replaced without any cost or questions asked as it was still under it’s warranty. Luckily, before it failed, I had a backup made of its contents. Backing up your data to various media is key.
I also have another USB flash device that is 10 years old. I treat it like a travelling floppy disk. The only one that has shown best compatibility among various systems used and shows little symptoms of wear.
Currently, I have another USB flash device which is starting to show a lot of wear. It’s primary cause is due to extreme data writing at low bytes. I have reduced it’s wear by optimizing the tool(software) when it was targeted a the source.
All this is great. I am not suggesting that the technology is a failure, however, when looking at cost and reliability, I prefer to have each of both worlds. From experience, Disc platters can sustain much greater amount of data wear than Flash. As proof, I still have 20 years old HDD, though now it no longer has a purpose due to it’s fading technology.
Hope that clarifies my comment.
Cheers!
There really is no comparison
There really is no comparison on relative reliability of USB flash drives vs. SATA and up SSDs. USB drives are not rated at anywhere near the longevity / usage.
I JUST bought a 240gb M500
I JUST bought a 240gb M500 for $100 last week. Is is worth sending it back in exchange for an MX100 256gb, or am i better off just keeping my M500?
great review allyn 😀 though
great review allyn 😀 though this line really needs a 1tb option.
according to this, yes you
according to this, yes you should exchange it (tho ssds are all pretty fast, and the real-life performance gains may be negligible, so ymmv)

Hi Allyn,
I just read a review on http://www.trustedreviews.com. They said,
“the MX100 is at greater risk of the electricity leaks that can effect transistors when they’re packed in such close quarters”, is this true?
