ADATA XPG SX300 256GB mSATA SSD Review

AS SSD BENCHMARK VER 1.6

Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data.  AS SSD, for the most part, gives us the worst case scenario in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

We had expected to see better benchmark results in both transfer speeds and IOPS performance, although the results are very good.  Test results such as this are specifically why we run a variation of different benchmarks, many conducting the same testing.

On the other hand, the AS SSD Copy Bench result is amongst the best we have seen and some very quick transfer speeds were achieved through the three file transfers.

ANVIL STORAGE UTILITIES PROFESSIONAL (BETA)

You may not see this for long (and its definitely not common) but you get a freebee simply for reading!  Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility.  Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize in our benchmark testing.

COMPRESSIBLE (FILL)

INCOMPRESSIBLE (RANDOM)

Providing both Anvil Storage Utility results gives us a birds eye view on how performance fluctuates when testing with highly compressible data vs incompressible data.  As we can see, response times slows a bit as does the total IOPS and write performance at high sequential levels when testing with incompressible data.

Understanding that our system starts and runs programs with highly compressible data enables us to understand why compressible data speeds are so important.  Conversely, many enthusiasts prefer incompressible testing as it is representative of transferring highly incompressible files as we might see in movies, photographs and music.

  1. the sx300 256GB costs $270 @ Newegg…

  2. How do we know if it is compatible with Lenovo T420s? Manufacturer website does not provide such information. Kindly suggest.

  3. Does the SandForce controller on this msata ssd is good than other controller? Which msata sdd is fast and best quality?

    • This is an excellent mSATA SSD and the fact that it offers 7% additional space just might be key here. With respect to controllers, the main competitors in the market today (SandForce, Marvel, Samsung) have all earned a reputation of quality simply because of company development and experience in the industry.

  4. I recently purchased this mSATA SSD for my HP Elitebook 2740p and performed a clean install of Windows 8 RTM. The SSD is a ADATA ASX300S3-256GM-C MSA which they list on their website as the XPG SX200.

    I frequently experience a Blue Screen on Windows 8 after resuming from sleep.

    The SSD is my boot disk. It’s about half full. Running chkdsk at boot time shows no errors. Windows Disk Management reports the drive as healthy.

    The Crash Dump analysis output (all the dumps are similar to this) shows the following:

    ERROR_CODE: (NTSTATUS) 0xc00000c0 – This device does not exist.
    BUGCHECK_STR: 0x7a_c00000c0
    DEFAULT_BUCKET_ID: WIN8_DRIVER_FAULT

    • I checked again today and I can confirm I have the latest firmware for this model.

      • Thanks for that Sol. I was just about to purchase this mSATA SSD to install Windows 8 on it on my ASRock PC! Will now just replace the standard HDD with a SATA SSD with the likes of a Vertex 4 or so. Thanks again for posting this 🙂

  5. Where is firmware 5.0.3/5.0.4?

  6. Work on windows 8?

  7. Be aware – I bought this from Amazon and returned it and tried again…. both times, this card does NOT WORK on the Drobo 5D.

  8. Great reviews. My question is simple, Crucial M4 256GB vs ADATA XPG SX300, what difference,if any, is there between these 2 ssd’s The m4 is 50+ dollars cheaper. Is the Adata msata drive , although better on paper, going to give me better performance on my laptop in the real world?

    • And real-world use, you, or even an SSD expert, cannot visually tell a difference in typical day-to-day operations. Both solid-state drives would do great in your system. Both have great reputations. Unless you are looking for something specific where higher incompressible data testing is necessary, I would simply look at the price.

      • Thanks when you say “visually” I interpret that to be things like boot time, program opening, shutdown times etc. It is the write speed that stands out for me the Adata being in the 500mb+ per second and the m4 not breaking 300mb per second. Those numbers really mean nothing in term of real life use?

      • Real life user in typical use yes. Unless you are transferring large incompressible files you will never be able to visually see a difference.

      • In real world i think the m4 ssd will perform as well as the ADATA drive. ADATA drive (sandforce driven) will never reaches the announced performance. It relates only an optimal situation with compressible data.

      • Yes but compressible data is what we see in operating systems and software and can’t be overlooked. In the typical user scenario, it would be impossible to tell the difference.

  9. So I bought the adata sx300 256gb drive I installed it but it appears to give me only 238.5 gb is that correct? I understood from your review that this drive gives us that 7% lost space or is that not the case?

  10. Please join the forums and posts screen shots of your system and not with the CPU states altered please.

  11. Which Adata sdd would you recommend today: the SX300, or SP310? Almost the same price (SP310 a tad cheaper).

    I have had two of these drives fail in my Msi GE70 within a year. I’m going back to conventional HDD’s.

    • You need to ask yourself what occurred…. Were they fresh installs? What was similar betwen both instances?

      • Here are a couple of similarities:
        1. Both were Adata SX300 mSATA 256GB SSD’s
        2. Both were installed in the same system (MSi GE70 Core-i7-3630M, 8GB DDRIII RAM, Nvidia GeForce 660M)
        3. Both crashed within less than 6 months
        4. Both crashed after waking up the laptop from sleep
        5. Both were gone from the BIOS after the crash
        After a couple of searches on Google I found out that I’m not suffering alone as these are crashing all over the place. It looks like it might be a problem with the Sandforce controller – but don’t take my word for it – I’m an accountant.
