Its slim 2.5-inch design fits both laptops and desktops, delivering rapid boot times and smooth application loads. Built for durability and backed by a 3-year warranty, this SSD is the perfect budget-friendly upgrade for professionals seeking reliable, high-performance storage. ## Description A high-quality product for the budget-minded among us, the Ace A55 is positioned as one of the most cost-effective SSD models. With its advanced SATA III 6Gb/s interface and an affordable price, you can now easily upgrade your old computer without spending a fortune. Still wasting precious time while booting your computer or loading applications? Then it's time to get rid of your old hard drive and switch to an SSD. Powered by SATA III 6Gb/s interface, the Ace A55 is able to boot your computer or launch applications within seconds. Equipped with an original controller and 3D NAND flash, the Ace A55 can not only guarantee stability and durability. It also delivers outstanding performance which enables 10-second quick boot-ups, shorter application load times and faster data transmission speed. Whether you are web surfing, enjoying a good movie, or have to handle paperwork, the Ace A55 will bring you a smooth, lag-free experience. A bad block management (BBM) mechanism detects and marks bad blocks to avoid storage in those blocks and eliminate access errors. And, even if errors do occur in new blocks during an erase, this mechanism can move the data to other effective blocks to prevent data loss resulting from the failed erase. The Ace A55 is one of the lightest and thinnest SSDs of its kind yet it is shock- and vibration-proof, because it contains no moving parts. Equipped with a S.M.A.R.T. monitoring system and ECC (error correction code) technology, it also promises higher data transmission safety. The Ace A55's auto-copy technology allows automatic copy operations from the SLC cache to the 3D NAND Flash inside the NAND without using the controller or DDR. This supports higher efficiency by reducing the controller's and DRAM's workload. Review: Value for money - This is a really awesome one. Value for money. I don't understand why SATA SSD of other companies are still that high. I mean we can get a gen3 nvme m.2 with 3GBps speed with that pricing instead of 500MBps SATA SSD. Review: does its job as a ssd. - good ssd drive. works well. I am using for music production purpose. my plugins are dam heavier than any games. the ssd handles it very well. worth buying ## Features - 【Versatility】Designed for content creators, DIY system builders, and everyday users who are looking to upgrade their PC for faster boot-ups, data transfers, application loads and response time. - 【Performance】Sequential read speed up to 500MB/s and write speed up to 450MB/s. - 【Responsiveness】Adopts 3D NAND flash and SLC Cache technology to improve overall performance. - 【Compact】2.5-inch SATA SSD (7mm) suitable for desktop and laptop computers. - 【Reliability】3-year limited manufacturer warranty ensures superior quality and reliability.

First some preliminary info: Unfortunately, the question was probably asked incorrectly, at least the vendor appears to believe so as the vendor provided the info for the A55 series. The S55 series is in sizes 120GB, 240GB, 480GB, and 960GB. The A55 series is in sizes (in GB) of 128, 256, 512 (and in TB) 1, 2, 4, 8, 16TB. All things being equal, they are relatively the same in performance specifications (S55 and A55 of nearly same sizes). However, the S55 series is pretty much defunct by now, though you can still find them available. Now, on to answer your question: TBW stands for Total Bytes Written. It is the standard of measure for how long the SSD drive will last, or more correctly, how long you can still write to it. In layman's terms, SSD drives can only have data written to them so many times (in actuality it is the "erase" function which clears a block of space on the drive that this really relates to) and so they in a sense "get used up" after a period of time. All in all it boils down to the old MTBF (Mean Time Before Failure) that regular magnetic hard drives (HDDs) are measured against. TBW is generally measured in Terabytes (unless otherwise stated) so as an example, if you have a 512GB (Gigabyte) SSD drive that has a TBW of 250 it means that you can write up to 250 Terabytes of data on the drive before you can no longer write to it. In this example, that means you could completely write to the entire drive (and erase/overwrite it) 500 times (512GB being half a Terabyte relatively). Once you have reached the TBW of the drive, you could no longer write to it, though you can continue to read the existing data on it for as long as the drive works "electronically". Hope that answers your question as well as possible. **Q: Does it have power failure protection?** A: does it matter? the purpose of power loss protection is to write data from the dram cache to nand (flash) in the event of power loss. If an SSD does not have dram cache (such as this), there are no writes to in dram to protect. does that necessarily mean a drive is good or will survive a power loss? depends on firmware-if done correctly, yes. dram is much faster, so for high end drives, dram is almost a necessity. some of them with dram to hit high performance numbers do not have power loss capacitors...if you're looking for an application or use case that needs both the performance of dram caching and power loss protection of that dram cache, you likely already know enough to know the answer. if you don't have one of those use cases, power loss protection is really a moot point. This is not a drive someone would use for a ZFS ZIL, or a virtual machine swap file datastore, or big SQL server temp db.. **Q: Is this a good boot drive?** A: I used to own a comp company..still build several high end rigs a year and enequivacly can say these are excellent "not " drives. Very stable through all functions esp here in Hawaii with sometime spotty power supply. Rgds and aloha Tim **Q: Anyone else have problems with this drive not registering on userbenchmark?** A: I have not had any issues at all with this drive. I just recently installed it on my pc and it works perfectly ## Customer Reviews ### ⭐⭐⭐⭐⭐ Value for money *by A***A on 29 December 2023* This is a really awesome one. Value for money.

I am using for music production purpose. my plugins are dam heavier than any games. the ssd handles it very well. worth buying ### ⭐ I made a mistake buying this 2tb instead of sticking with 1tb samsung *by S***I on 8 July 2023* There is a reason why this product sold at less price. Like every other customers I took fall for the offer and now suffering with no replacement I received a non working 2tb SSD card which is not recognised in my system. While my return window is still opened, Amazon denied to replace this bad SSD with working one. I have been cheated by both Amazon and the seller. Buy at your own risk, if you want a long-lasting product better buy 1tb Samsung instead of this poor quality 2tb product. I don't know what I am going to do with this useless drive which I spent more than 7,500 rs. If you see non returnable product, please don't take a risk and buy from Amazon. Better visit to your nearest markets and spend extra money to receive a quality product. This was unexpected from the best online shopping. Cheated and robbed by both.
