    I had it in my Mac Pro as storage, not the main OS drive, bought it last June and a couple of weeks ago my Mac started acing up, crashing, freezing...I methodically went through the other discs and this one was causing the problem..... I have contacted their support and see if they can do anything for me....shouldve spent the extra on another Samsung SSD...oh well, you live and learn !

    I bought this as a replacement for a 1TB mechanical drive I had on my DIY NAS. So far so good. No problems with BTRFS and it remains powered 24/7.

    After getting a PS5 using my older PS4 Pro in my bedroom was becoming quite annoying. It seemed like it was frozen half the time waiting for menus to load. After sliding this in and downloading the OS my PS4 was at least 10xs faster. Now I find myself firing it up way more often. For anything that has a hdd this upgrade is a must and the price of this SSD makes it a no brainer.

    Use this Silicon Power SSD as a NAS back up drive even though I know it it not designed for NAS storage. But with the price this low I prefer the Silicon Power SSD over a mechanical drive. Anyway, the Silicon Power SSD and the NAS has been on 24 7 non stop for three months straight and the SSD has been working fine and there is 99% life remaining as it is shown on the drive analysis after three months of non stop usage. Overall good SSD, recommended.

    Have had this drive Since December 9th of 2022 (It is now April 2nd 2023) and so far it is still going ok. The storage is as advertised at the full 2TB, Which for the price was what sold me. Even with the neutral to negative reviews that I had seen. However, The average response time is worse that the 2TB Seagate HDD. Im seeing an average response time of over 500ms on average with occasional spikes to 900ms. The HDD averages around 3.2 to 12ms. The only reason that I have not really noticed the delay is im not running the highest graphics in games that require the fast response. Just simply needed more storage. Not a terrible SSD, but not responsive enough for fast random read/writes. Good for bulk storage. (Longevity is still in question).

    Ive purchased these drives twice, one 512 GB and one 2 TB drive. The 512 GB drive failed within one year. When it failed, all reads and writes to it were incredibly slow, and any system that tried to boot off of it would crash, though I was still able to recover data from it. I called in the warranty on that drive, and both its replacement and the 2 TB drive exhibited the same issue where it *looked* like it was working, but its read / write performance was incredibly inconsistent. The systems booting off of those drives would occasionally freeze for seemingly no reason and at random times. I couldnt figure out what was going on until I did a benchmark of the drives and saw how bad the read speeds were. In particular, I noticed that sometimes the read speeds went crashing down to ZERO. That certainly explains why my systems were locking up. I used a free app called HD Tune to do the benchmarking. Ive attached a few of the graphs it produces as it runs to this review to illustrate what a failing drive looks like. If you buy one of these drives and see something similar to what Ive shared, then definitely RMA those drives ASAP because they will cause your system to freeze or crash. I called in the warranty on both the replacement 512 MB and 2 TB drives (for a total of three RMAs), and the replacements do seem to work correctly. So luckily not all of these SSDs have that issue. But its worth noting that three out of the five of these drives Ive had were faulty, and it still remains to be seen how long these two new replacement drives will last.

    Easy to install ssd but pain to get free cloning software for it from manufacturer. Luckily there are free packages out there (clonezilla if you are somewhat tech savvy).

3D NAND Technology for Enhanced Reliability and Power Efficiency

Applying the advanced 3D NAND flash, Ace A55 features higher reliability and better power efficiency than traditional SSDs equipped with 2D NAND flash. The A55 offers improved endurance and longer battery life that you"re able to work longer without frequently recharge your laptop.

High Transfer Speeds for Fast Start Up

Powered by high quality controller and original synchronous NAND flash, the A55 delivers incredibly high transfer speeds that enable short boot time, fast application loading and quick file processing.

SLC Cache Technology for Performance Boost and Longer Lifespan

The A55 especially applies the ”SLC Cache technology” that allows all data to be written in the SLC portion first and leads to higher peak writing performance. In addition, the technology can reduce write amplification and thus offer better endurance and longer lifespan of the SSD.

Free-download SSD Health Monitor Tool - SP Toolbox Software

The A55 comes with a free-download SSD health monitor tool - SP Toolbox Software, which is especially designed for you to easily monitor the current health status of a SSD. By such, you can run a performance test, get an overall health evaluation and check detailed information about your SSD, including used space on device, device temperature, total bytes written, S.M.A.R.T. status, erase count status and block numbers.

*Please download the software at SP Official Website.

Absolutely Reliable with Bad Block Management

The A55 is built with Bad Block Management, which can continually monitor and replace bad blocks to keep your system in good condition with prolonged lifespan of a SSD.

Multiple Techniques Supported

The A55 is one of the lightest and thinnest SSD of its kind yet it is shock- and vibration-proof since it contains no moving parts. Furthermore, S.M.A.R.T. monitoring system and ECC technology are equipped to promise higher data transmission safety.
