Adata Premier SP550 SSD Review (240GB)

CRYSTAL DISK BENCHMARK VER. 4.0.3 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

Adata Premier SP550 240GB CDMCrystal Disk Mark shows us again read and write speeds that are in line with the 560MB/s read and 500MB/s write spec. 4K speeds look very good as well with reads reaching 34MB/s and writes reaching 151MB/s.

AS SSD BENCHMARK VER 1.8

The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

Looking at the performance in AS SSD we can see that it achieved an overall score of 904 points. As normal read and write speeds are a bit slower than in the other benchmarks with reads coming in at 526MB/s and writes reaching 478MB/s. AS SSD also gives us a look at IOPS performance. For reads it was able to deliver performance over its 75K rating, reaching 78K IOPS, however, during writes the IOPS are half of specification, reaching only 25K.

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. 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 use in our benchmark testing.

Finally, Anvil shows off an overall score of 4155 points. Read and write performance is in line with AS SSD’s results, however, in terms of IOPS we see an improvement in writes. The Premier SP550 reached just shy of 70K write IOPS, which is much better than AS SSD revealed.

  1. 80MB/s write on TLC area ?

    Thats really really bad. That means 120GB model would only achieve 40MB/s at best.

    Looks like hynix TLC isn’t really on par with micron or toshiba flash.

    • That fourth ‘Performance’ star is more than a little bit generous.

      • To be fair, look how well it does in PCMark 8. Sure, large transfers aren’t great past the cache buffer and are slower than the Samsung EVO, but in PCMark it is on par with it. In most consumer workloads you have short bursts of writes. For the given use and market segment, the performance, while slower than the competition in large write transfers, is still decent.

      • I wounder how endurance fairs, given this clearly isn’t the best TLC out there.

      • Well, we are guaranteed what the specs state. The 120GB and 240GB models are rated for up to 90TBW, the 480GB is
        rated for up to 180TBW and the 960GB model is rated up
        to 360TBW. If it wears before then within 3 years one can RMA.

      • Hello, I have been using this drive about 1 month, I found out that Reallocation event count RAW value is 7 from the first day and drive temperature is around 36C- 42C. Is that normal?

      • What are the top 5 consumer ssds for large file transfers in your opinion?

      • Why type of drive are you looking for? PCIe, SATA, M.2, etc?

      • SATA. I have an old motherboard. M3a78pro

      • Your only going to get around 200 MB on that MB-
        Restricted by it’s 3Gb Sata ports.
        Modern MB have 6Gb ports that max out around 500 MB.
        But in answer to your question
        Samsung 850 pro.
        Sandisk extreme pro.

      • Tanks for the suggestions. I have a Asus g74sx laptop also. I know the Samsung pro and sandisk pro are good but I am looking for the 5 best ssds at large transfers not just the top two. So I can get the best deal on price.

      • Well, there are still many mainstream drives that can do that, you don’t need to buy the best of the best. The BX 100 and Samsung 850 EVO can sustain write speeds and are usually popular choices. Just stay away from the dirt cheap value segment, especially TLC if it isn’t 3D.

      • Hi Mike, Forgot to mention in earlier post-Capacity of the drive plays
        a big part in the write speed.
        Example-If you wanted only a 120/128GB size then your almost
        totally limited to Samsung pro.
        If your considering 480/512GB then most MLC drives will be fine.

        Personally I will only buy drives where the flash has been cut and
        binned by the manufacturer-So that cuts out the likes of A-Data
        and Kingston-This is only personal preferance-Remembering
        that this was what gave OCZ a 60% failure rate on some of their
        drives.

      • All of those qualifiers don’t get reflected in that Performance star rating. Perhaps an additional category like ‘Price:Performance Within the Consumer Value Level Peer Group’ is needed.

      • I have been thinking about this and will consider this highly for our future reviews. Thanks for the suggestion!

      • Smaller drives may not need fast transfer speeds ( OS ) 120gb 240gb ,but the larger drives are used for ( backup, storage, large transfers ) 480gb 960gb. these larger drives need more write speed after the buffer.

  2. Good thing you guys test these ssds for us consumers. thanks for the reviews! Some or maybe more than it should be of these new ssds are slow. 80 mbs transfer speed for a 30gb file I think that’s terrible, when these ssds are advertised for 560 read / 510 write max. hdds are faster than that. If not for the slc caching and the dram buffer how slow would this new nand really be. These new controllers with their slc caching and there dram buffers paired
    with inferior nand hide their true speed and give some new ssds a bad name. I know ssds are all about access and read speeds , but come on cant we get decent transfer speeds on large files on sata? Why if we want decent transfer speeds we now have to have a pci ssd? And average users do transfer large files every now and then.

  3. Please change: “Overall, there are 8 NAND packages on our 240GB model with room for another 8. The NAND is supplied by SK Hynix. Each package is 32GB in capacity for a total RAW NAND capacity of 256GB. Since the usable capacity is 240GB, we can see that it is over provisioned by ~7%. The total usable capacity once formatted in our system is 223GB.”

    To:

  4. If you are not using your laptop for gaming our any thing that intensive like rendering these ssds will do the high end ssds are costly

    • I beg to differ, at least for the gaming part.
      This seems like a nice little SSD for entry-level SSD game loading speeds. And since games don’t write much, save for installation and updating/patching, the slow-ish writes won’t matter as there won’t be “frequent” Gigabytes of writes for games.

      Also, if you don’t mind, you could use some punctuation in your sentences. I had to read that several times to get it.

  5. And before you say it i live out in out back Queensland and a lot people out here are cattle people so there funds are restricted so they dont have the money for they high end stuff but they want something that works and will do the job ssds are more responsive faster but the high end ones can be a bit costly for what they want them for

  6. Why this (240GB sp550) does not on and is not properly detected on Lenovo T500 (p8600cpu) but runs fine on older hp nc6320 (coreduo 1,6 ddr2) and newer hp 6540b (i5, ddr3) ? Both with compatibilty and ahci setings ?

    • try cloning the drive, then swap, worked for me to get detection of unrecognized drives in many a machine in an enterprise environment. macrium reflect free – for clone

    • Just wanna put it out there.
      MiniTool Partition Wizard works great too for migration. Its free.

  7. Switched from kingston UV300 240gb drive to the adata SP550 becuase i felt the kingston had degraded overtime
    big mistake this adata caps at 40mb/s write speeds whenever you write more than 16GB of data
    and reads seem much much slower
    it was cheaper so.. bleh time to get a real fast drive

  8. So far, I’ve been using the Adata Premier SP550 SSD Review (240GB) for about 4 months (since Mar-2016), and things are good: My laptop bootup speed is up by about 3 times, to under 30 seconds! Worth the upgrade from HDD to SSD!

    Only thing was the need to use a disk imaging software to copy the laptop OS & setup from the old HDD to the new SSD.

  9. Hi guys, I just pick this SSD for a good price, but after few review I’m a bit concern about the performance of this drive, is still new, I will install it in a couple of days, should go fo a new one? o better product?, I’m using it mainly for documents such word, excel, pds, and some java development in netbeans, show I be worry or the drive is good for my work? thanks to all
