ADATA SU900 512GB Ultimate SATA SSD Review

Final Thoughts & Conclusions

ADATA SU900 Ultimate SSD Retail Packaging 512GB Model

The ADATA SU900 Ultimate SSD series is ADATA’s flagship SATA II SSD model that was designed for someone needing a 2.5″ storage drive to replace an aging hard drive (HDD). This drive features the latest 3D MLC NAND Flash, SLC Caching, and large DRAM cache buffer to ensure it is reliable and fast. Those features and the 560 MB/s sequential read and 525 MB/s sequential write speeds make this a solid choice for a SATA III solution. The accessory bundle that includes access to migration software is the icing on the cake. When it comes to performance this drive performed at the level we expected to see on the SATA III interface.

ADATA SU900 Pricing

What is the negative? Price. The ADATA SU900 Ultimate 512GB SSD that we looked at today has ranged in price from $169.99 all the way up to $229.99 over the past 60 days. ADATA says the NAND Flash shortage is to blame, but consumers just care about the retail cost. At $169.99 this drive is a good value and something we’d recommend, but at $229.99 this model is something we’d tell you not to get as you can get an M.2 PCIe NVMe drive like the ADATA XPG SX8000 512GB for $211 shipped ($0.39 per GB). When we wrote this review on May 11th the ADATA SU900 Ultimate SU900 was $171.99 at Newegg and then on May 12th when the review was published the price was back up to $229.99 shipped. Amazon has it right now for $210.54 shipped, so we’d suggest not buying this drive at those prices and waiting for sales. So, if you can find this drive priced in the $165-$175 price range we recommend it, but if it’s in priced over $200 we suggest waiting. If your platform has an M.2 slot on it we highly suggest looking to the newer M.2 PCIe NVMe solution if you can.

LR Recommended Award

Legit Bottom Line: The ADATA SU900 Ultimate SSD performs well for a SATA III and should be on the short list for those looking for a 2.5-inch that uses 3D MLC NAND Flash memory.

    Good warranty … fair price … outstanding TBW.

  • Nate, it could be better if you add Windows booting time, applications loading time, games loading time, and file transfer speed (or time) to reflect “real world” performance.

      Thanks for the feed back and I wish there was a fast and easy way to do what you are asking when you are behind on reviews and only have so much time in the day.

      Boot times are tough to do as there really is no good way as stop watches don’t work well. I’ve done them as recently as last month though and had a script that times how long it took to open chrome – http://www.legitreviews.com/intel-optane-memory-review-32gb-module-3d-xpoint-tested_193876/3

      It takes under 150ms to open the chrome web browser, so you can’t stop watch that. I’ve not looked into making a script for game times, but if you know how to make one or can help let me know.

      The other issue is ROI (Return on Investment). Installing Windows on each drive and setting up the drives and downloading the latest updates takes a good 1-1.5 hours. You then have to load up all the apps and games from our local steam files and then do all the testing and extra charts. It might add an extra 4-6 hours to the review process, but I’m not sure it’s really worth the time.

      For example the market for this drive is really small. ADATA won’t be selling millions or hundreds of thousands of these drives as the market is pretty small. Likely only tens of thousands of drives will made and sold before this product goes EOL. The traffic on specific SATA SSD reviews is small. Take YouTube results for example. There is only one review on the ADATA SU900 Ultimate SSD on YouTube and it was from 2 months ago and has just 1,400 views. (see below) I’d love to tell you that this review has been read 100,000 times since it was published, but it hasn’t been. It’s been read by just over 1,000 unique visitors so far and no one has bought a drive through any of our Newegg or Amazon affiliate links. The traffic on SATA SSD reviews is pretty small to be honest and is one of the reasons you’ve seen so many hardware reviews sites close down in recent years. The ones that are doing well have diversified (Many are focusing on mobile, and some are doing movie reviews and other stuff to bring in a wider audience to get traffic numbers up).

      • As a hardware reviewer myself(one working on the SU900 currently at that) I feel your pain specific application times are so small and honestly unless a drive is particularly amazing(or horrible) the real consumer impact is very small it’s something I struggle with drawing a final conclusion when I have to look at all the differences and ask myself, can the reader actually feel 20mb/s ? will they notice the .02 second difference here or there? SATA SSD reviews need to be done but we can only spend so much time on a specific drive before we’re beating a dead horse.
