ADATA SU635 240GB 3D-NAND SATA 2.5 Inch Internal SSD (ASU635SS-240GQ-R)

This review is targeted toward businesses that likely do not need gaming features. This is not a gaming SSD; anyone building a gaming rig should use an NVMe drive in their machine and never look at SATA in any form as a boot option. My company has installed around two thousand of this drive model in the last three years. As a result, I feel somewhat uniquely qualified to write a review on it! I am sure there are other contractors who have installed quite a few of these drives as well and I would be interested to hear if their experiences match mine. Pros * This drive is shipped in easy to open packaging. It takes approximately three seconds to remove this drive safely from the packaging. When you are doing one, who cares right? Welllll...... This is my first pro for a reason - when you are opening two hundred drives this is a very important metric. * Read / write speeds are very close to advertised speeds * Price / performance / GB ratio is close to the best we've used * Our observed failure rates are currently three out of the ~2000 drives we've installed which is the best of any other brand SSD we've tried (we've extensively used all major manufacturers) including top tier producers like Samsung. We do still use other brands for specific use cases but these are the most reliable SSDs that we've found. Cons * The drive housing is flimsy and lacks the heft or sturdiness of higher end drives. * Certain Dell BIOSes have issues with this drive series. They will randomly reboot and then a BIOS level message will show saying that there is no hard drive detected. We've seen it on multiple models but most frequently on Inspiron 3471 and Vostro 3470 units with not-current BIOS versions. If you do use this in a Dell from the last two years, I would advise flashing to the newest BIOS version before you image over as you definitely don't want it crashing in the middle of the update. We actually did have that happen once and were fortunately able to recover the machine. * These don't play all that well with 2.5" to 3.5" adapters with electronics in them like Icy Dock units and will occasionally cause IO errors with some BIOSes. Try looking for a 2.5" to 3.5" adapter that doesn't use electronics. There are some Dell server-specific models that work well for using them in servers - Dell part number 9W8C4 is good if you use some models of Dell server and there are lots of other manufacturers that make these types of adapter for other systems. We have three cases in which we use this drive: 1) We have a client that wants to upgrade one or more of their office workstations to SSD. We have used many models but I currently prefer this because of the factors I list in the Pros section above. 2) We are selling a low cost workstation model that we have upgraded with additional RAM and an SSD. We use these vs m.2 drives because we want a drop in replacement for the hard drive that came with it. 3) We have a few clients that are non-profits and rely on donated hardware. In a few cases, I decided to use these low cost drives in donated servers instead of used hard drives. Surprisingly, none of these (of various sizes) I've used in these server use cases have ever had an issue. In the three years since we started using them, zero out of probably thirty have failed and none of them have ever lost RAID sync. These are all obviously low-write environments but they are definitely getting more use than a normal desktop PC and I think that's pretty good considering how inexpensive these are. I wrote this review more or less to thank Adata for making such a quality product. I don't often write reviews and usually when I do they are negative but the low rate of failure we've seen on these is simply astounding. It makes my job sooooo much easier and more lucrative when I don't have to deal with pissed off clients expecting free work because a part we sold them failed in under a year. This drive won't win performance awards from gamers but the value and reliability it represents for businesses is absolute.

Phenomenal SSD for the price! I was so hesitant (HP Probook 4440s i5 2.30ghz 8gb RAM) I didn’t think it would boost my laptop the way it did. It took about 5 mins for my laptop to boot up with no lag, when I did the upgrade my laptop was brand spanking new. It saved me so much money because I was going to spend hundreds of more dollars on a new one. I’m able to play flawlessly 4K quality movies, the boot up is less than 30 secs. I’m running Windows 10 Pro which is heavy on an older laptop like mine and it handles flawlessly with no lag time. Now it’s been a few weeks so I’ve definitely put it through the test, I do not game so I can’t speak on that but everything else, even video editing is up to par. I will definitely but again, my package was nice and simple, just remember to upgrade your BIOS before you install your new SSD it’s important so you can have a flawless experience with the SSD.

If you've got an old, slow laptop you're looking to breathe new life into, this is the SSD to use. It's cheap, it's plug and play, and it sure beats any HDD for speed. The storage capacity is 240gb, so I would not look to store movies or games on this, but for a laptop this fits the bill just fine. Pair this with some new RAM and you can definitely save a few hundred bucks not buying a new laptop. If you've got an old, slow desktop you're looking to upgrade, get one with a little more storage if one drive is your only option. If you're comfortable keeping your larger files on a separate drive, this is great for an OS or boot files, not for mass storage. TL;DR: Great speed, good reliability, small storage

Great entry-level SSD with solid everyday performance I installed the ADATA SU635 240GB SSD in an older Dell Optiplex to give it a new lease on life, and it did not disappoint. Boot times are now under 20 seconds, programs load quickly, and general responsiveness is far superior to the mechanical hard drive it replaced. For everyday tasks like office work, web browsing, and streaming, this drive feels fast and reliable. The 240GB size is just enough for a light user or secondary machine—Windows plus a handful of applications fit comfortably, though heavy gamers or content creators may want to step up to a larger capacity. Build quality is good, and installation was straightforward with the 2.5-inch form factor fitting neatly into the bay. It runs cool and quiet, which is a nice plus for compact systems. This is clearly aimed at the budget-conscious market, and while it doesn’t have the write speeds of higher-end NVMe drives, for SATA it performs well. It’s an affordable way to extend the usable life of older PCs or to set up a speedy basic workstation. Bottom line: A dependable, wallet-friendly SSD that makes an older computer feel new again—ideal for everyday users who need a simple, reliable upgrade.

Brought extra life to 2 aging laptops. One was my lightweight travel laptop, an Acer Aspire One whose hard drive was always the limiting performance factor. This 2011 vintage notebook is great, works anywhere around the world, but it was just too slow nowadays. With the new SSD, it will last a few more years running 32-bit windows 10. Now it's memory limited, but I can't expand it beyond the 2 GB physical limit. Set the virtual memory high and hope for the best. It's working OK and tolerable for a travel laptop. The other laptop is an HP 6930p circa 2008/9. It's fast enough now for the wife to use as a secondary PC for the times she needs a PC. Her primary is a Macbook Air.

Replaced an aging PC with an HDD. Went from a minute of boot time, to maybe 10 seconds. Adata is a Taiwanese co, so you get a high quality SSD at a great price. Comes with software to do drive cloning. Bought a 3.5" adapter. Overall, just perfect.

Worked as I'd hoped and haven't had to contact support or customer service.

So i ended buying this SSD for an old computer I have, to use as a media server and stream relay point for my high end rig. Problem was... when I installed Windows 10 it took minutes just for the browser or applications to open up. The hard drive was starting to fail I assume. Anyways I got this today and installed it in the old PC and the boost was insane! Previously it took literally 3-4 MINUTES or even longer for the computer to go from a cold start to fully loaded windows. With this new SSD it now takes SECONDS for the computer to go from a cold boot to fully loaded windows. Item came super fast and in good packaging. Seems like a good quality product for the crazy low price. But Adata products are usually decent, and they are a good company. Ive never had any problem with any of their products. So highly recommend this one. If you have an old computer you want to revive. This will certainly do that.

Works.

I've had this running for a few months and have no complaints. I got it as a replacement for an HDD, and , of course, it is seriously faster. I haven't done any measurement of transfer rates etc. because all I was looking for was a stable, faster boot/OS drive.
