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. 3-year Warranty The Ace A55 is backed by 3-year warranty. *Please register your product via SP official website to get the complete manufacturer warranty services, product support and more. Box Contains 1 x Silicon Power Ace A55 Solid State Drive Review: Good value - Its super fast and quiet of course. There were some reviews mentioned it lags when writing large files to it. This is true because it does not contain the buffer circuitry on the SAMSUNG ssd drives. This will not be an issue for you if you use Aomei or EaseUS partitions software. There is a box you can check, optimise for ssd, to speed up the cloning massively. My steps to move OS- 1 - Clone the System Reserved Partition 2 - Clone the OS partition Be sure not to miss step 1. Of course you can clone the entire drive it is much simpler but I did not do this because it will take forever. What you will want to have in case of boot issues: -Windows PE disc -EasyBCD (critical), and a way to run it Sustained write speeds will not be much of an issue for most people once it's migrated / cloned or setup. If it is an issue for you, shell out the shekels for the Samsung. As all flash memory does, it operates way faster with small files, sustained writes and probably even reads, are going to slow down after about 500mb of file size This is a great value and it will perform fine for most users. Very cool to have and great value I do not regret this purchase even .001%. Would have like to get the Samsung, but its 3X as much money, for what boils down to nearly the same thing, once the drive is cloned Make sure to check optimize for ssd in cloning software. Definitely use fast mode clone (copy files) in Aomei to save yourself hours. I'd probably avoid using clonezilla because it wiped my boot record then failed to clone, and it takes forever in sector clone mode. Do not expect the disc cloning to be easy or fast, it will not be unless you clone entire drive, and if you do that and your drive is huge then prepare to wait overnight if not days. So is why I suggested the steps above. Only took about 30 minutes to clone a 270 gb partition just now. works best to just not delete anything on source disk and you will be fine as long as you are able to run EasyBCD again (make sure that you can!) Review: Died in less than a year - Update: I RMAed this and Silicon Power came through! I sent it back as it was under warranty and they replaced it despite the fact that it cost $90.97 in March 2025 and now cost $219.97!!! Props to Silicon Power!!! The thing was hardly used and now it’s dead. Computer recognizes it , but hangs when trying to use it. Chkdsk hangs and cannot complete. Tried this on multiple computers and through a sata to usb dongle. I went to the homepage and the model number of this particular device does not show up when searching the warranty status, so out of luck. DO NOT BUY. ## Features - 3D NAND flash are applied to deliver high transfer speeds - Remarkable transfer speeds that enable faster bootup and improved overall system performance.

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 ### ⭐⭐⭐⭐⭐ Good value *by T***S on November 9, 2024* Its super fast and quiet of course.
