## Description

High Transfer Speeds for Fast Start Up Powered by high quality controller and original synchronous NAND flash, Ace 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.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: The company spec is a bit conservative. I get about 3500 for read and around 3200 for write with CrystalDiskMark benchmark. At about 250-300GB of usage, the cache will run out and starts to slow down like an old school hard drive. This happened when I was cloning a backup disc only. Update - It's been 5.5 years and the drive still works great with no drive errors or heating problems. I'm currently in the market for a new Gen 4 SSD so I came back to look up the brand and leave a quick update. I highly recommend this brand for quality and affordable SSD.

Most All M.2 / NVME drives deliver performance. Silicon Power's 512GB offers everything a Samsung M.2 has at a lower cost. (I own two of these). This review will start out with practical information the moving into the more technical aspect of the SP 512GB NVME drive. This will be a long review. The biggest concern for anyone buying this is: "How can I use this if I don't have a slot on my motherboard for a M.2 SSD?". You need to get an adapter like this: QNINE NVME PCIe Adapter, M.2 NVME SSD to PCI Express 3.0 Host Controller Expansion Card This M.2 NVME SSD is the right "key" for the above adapter. The "key" is just the notched pattern for the NVME drive. (without getting too technical about it). You can put the drive + adapter into any PC that has a PCI-e slot. BOOTING from the NVME Drive may or may not be supported by your motherboard. Your operating system has to be 84-bit and supports UEFI; Windows 7*, 8*, 8.1* or Windows® 10. (Check your motherboard information about UEFI and NVME) If all this sounds technically confusing you can do this: 1) boot off a regular 2.5 inch SSD drive (have your Operating system on it). 2) install the PCIe adapter + M.2 NVME drive into your PCI-e (x4){version 3.x} slot (check your motherboard specs) 3) make the M.2 a secondary drive like D: or E: or F: (all you have to do is format it, windows will give it the drive letter) 4) install any heavy loading programs on the M.2 I have this above outline configuration. Heavy programs or data goes to my M.2 Drives. You can even get two of these and make the M.2s into a RAID 0 stripped drive for double the speed. My advice is to format the M.2 as ReFS.ReFS protects against data corruption. (see attached image) (SKIP this section if you are not interested in ReFS formatting) Checking if TRIM is set for your ReFS formatted drive: 1) click on start or type in the windows 8/10 search box "CMD" 2) once you see CMD right click on the black icon and select "Run as Administrator" 3) type in the black window (Command Prompt) that just opened: a) fsutil behavior query DisableDeleteNotify 1) NTFS DisableDeleteNotify = 0 (says that TRIM is active for NTFS) 2) ReFS DisableDeleteNotify = 0 ((says that TRIM is active for ReFS) 3) if you get = "is not currently set" for either NTFS or ReFS You can enable it with the following command: a) fsutil behavior set DisableDeleteNotify ReFS 0 (this will set TRIM for ReFS) b) fsutil behavior set DisableDeleteNotify NTFS 0 (this will set TRIM for ReFS) Silicon Power M.2 NVME Drive: Speeds: (Crystal Disk Mark) {See attached image} (NTFS formatted) - READ and WRITE speeds: 2,000 MB/s (ReFS formatted) - READ speeds: 2,000 MB/s - WRITE speed: 634 MB/S (due to error/checksum checking) Write speeds are slower on ReFS due to error/checksum checking. 634MB/s is still SSD fast. ALL NVME drives are subject to thermal throttling which means once the M.2/NVME drive reaches a certain temperature the onboard chips will throttle down the speed/transfer to save the chips from overheating. Larger, longer transfers will trip the "thermal throttling" so just be aware it isn't the manufacturer's fault but the nature of the NVME design overall (across all manufacturers) My systems have SP SSD drives installed. I do large data transfers almost daily. SP drives keep pace with Samsung on speeds. Reliability can't be gauged on a short-term basis. Most of my drives are a year or younger in age. I do suggest trying either this M.2 drive or one of SP's other SSD drives. If you have an older system that doesn't have PCI-e (3.0) or greater to go with a regular 2.5" SSD drive. You really won't notice the difference. If all this sounds overwhelming find a geeky friend to help you out. I hope this information helps someone out. I always try to revise my reviews as needed.
