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 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.. Review: Good value and long lasting - Can't believe how long it lasted for the value, several years with no slow down, greatly improved the boot speed and load times of the aging laptop it was fitted to. Easy to install if you know what you are doing, great budget option Review: this impressed me so much after the first one that ive just brought 2 more of the same. - So if (a couple of years ago) you had told me that a half terabyte SSD would be less than the (then) price of the same size hhd i wouldn't have believed you. Zoom forward to today and often, the even faster m.2 nvme drives are cheaper still on a per gb basis. However for builds such as the updating and speeding up of both my HP enterprize z600/z800 builds which wont easily boot from nvme, and (for the same reasons) my updated Mac Pro a1186 builds for music studios, these are the perfect addition. Faster than any given hdd, and with using it in older sata 2 systems, it will run as fast as the system underneath can chew through data. What i will mention is that, although i was initially nervous as to using a dram cacheless drive after previous issues with older equivalents from other brands, i can confidently report that the tiered nand flash approach that this drive uses is perfectly suited for the application and plenty fast. It uses a smaller and lighting fast single layer nand flash cache, (exactly as a dram cache would be utilised, but in many cases significantly faster than the old and slow ddr3 used) it then moves the data archived onto the still fast but less-so qlc nand which is the size of the drives headline capacity to store. Again at the £44 i paid this is a no brainer. Good quality, great price and no issues and all testing using crystal tools reports at least advertised speed on a fast top end HEDT platform and in some cases its actually run faster than advertised. ## Features - 3D NAND flash are applied to deliver high transfer speeds. Operation Voltage: 5 Volts - Remarkable transfer speeds that enable faster bootup and improved overall system performance. The advanced SLC Cache Technology allows performance boost and longer lifespan - 7mm slim design suitable for Ultrabooks and Ultra-slim notebooks - Supports TRIM command, Garbage Collection technology, RAID, and ECC (Error Checking & Correction) to provide the optimized performance and enhanced reliability - 3-year warranty.

Circa 560mbps read and 420ish write. **Q: would this fit a would this fit a toshiba satellite C55-A-1R8** A: No personal experience with the Toshiba satellite, but if it has a 2.5 inch drive with sata connection plug it will fit, remember the Toshiba satellite will have to recognize a 1TB drive, maximum hard drive size will be found in you manual. **Q: Will this work with an android rablet** A: you looking for SD card not an SSD! so no it doesnt not work with rablet! it also doesnt work wit tablets!

The first one was bought a couple of years ago, the second recently, and overall they offer very good value for money as secondary storage. They're a QLC NAND based DRAM-less SSD. That means write speeds are dependent on whether or not you fill the SLC cache in a copy operation, which in turn depends on the remaining capacity as it treats some of the unused QLC as SLC. Using Macrium Reflect to copy the partition from the old HDD was a bit slow, around 50Mb/s for the 123Gb of data. However, copying 2 large datasets of 50Gb and then immediately another 80Gb ran at 200-400Mb/s for the most part for the large files in each, with occasional drops below 100Mb/s. This is more than acceptably quick given the low price. I wouldn't use cheaper QLC as a main boot drive, but as secondary storage for large game installs there's nothing wrong with it. Once installed most games have lots of reads and relatively few and small writes. My only gripe is the screw fittings. I had to use a Dremel to shorten the old HDD mounting screws by 1-2mm to get the tray to slide into the laptop mounting bay. For some reason when using the side mounting holes the screws catch and jam on the underside mounting threads, which as the photo shows wasn't the case with the older HDD. I only had this issue with 1 laptop and drive, it was annoying but doable. ## Frequently Bought Together - Silicon Power SSD 1TB 3D NAND A55 SLC Cache Performance Boost 2.5 inch SATA III 7mm (0.28") Internal Solid State Drive - Cable Matters 3-Pack 6.0 Gbps SATA Cables 45cm (SATA 3 Cable, SATA data Cable, SATA Cable) Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/94047539-silicon-power-ssd-1tb-3d-nand-a55-slc-cache-performance](https://www.desertcart.tn/products/94047539-silicon-power-ssd-1tb-3d-nand-a55-slc-cache-performance) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-07*
