ADATA SU635 240GB 3D-NAND SATA 6Gb/s, 2.5" Internal Solid State Drive

There are a lot of reviews claiming problems with a lot of generic replies "thank you for helping me with choice!" These drives are pretty solid for the price. They're not the fastest SSDs but much faster than mechanical drives. A friend was thinking his 2 year old Costco computer was needing to be replaced because it was so slow. A drive that runs $30 and a quick drive clone and he's blown away by the performance.In testing, I averaged over 500MB/s read and juuuust shy of 500 on write, about 490MB/s. It's a great investment to kick the performance of a machine up and extend its usable life. I have one of these in an old HTPC with a Q6700 from 2006 and the machine boots in about 15 seconds. The SATA2 bus obviously limits the potential of the SSD but it's still plenty fast.Seriously, for $30 you can revive your old box to be a responsive and snappy machine. I've recommended and installed these for several friends and they've been enjoying trouble-free performance for quite some time.

I have a laptop I purchased around 2010, i3 Mobile, integrated graphics, 3gb ddr2, 320gb hdd, Windows 7. Eventually being upgraded to windows 10.I eventually built a gaming Pc, then upgraded it and eventually just built a new one. The laptop gathered dust as it hardly saw use. College provided me with Thinkpads and Macbooks, so the old laptop had no life for me, and honestly was too slow to push onto someone else.I purchased and installed the most advanced CPU the motherboard supported without the thermals being an issue, an i5, upgraded to 8gb of ram (as it was the max), and replaced that old hard drive.I had not touched the hard drive at first. I tried experimenting with duo booting Win 10 and Zorin linux. It was okay but not really practical. After not having the Macbook that I had grow accustomed to in college for art work, I decided to purchase this SSD (as im using a similar make in my gaming pc as I type), and its working great. This time I only installed Mint OS after playing with different makes. It is shockingly fast. Gaming is fine given it still has a 10 year old int graphics inside of it. Files load fast, searching loads fast. Honestly, Shocked it preforms so much better with this ssd. Obviously most SSDs would improve off of a HDD but like, if you need an SSD that is cheaper and doesnt require every feature, say for an old laptop or a relative who isnt huge into tech, I suggest it.

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.

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
