A classic 2.5-inch solid-state drive with SATA3 connection, which stands out among other budget SSDs due to its impressive memory capacity of 4 TB. This solution is suitable for users who need large storage for multimedia files, backups, or replacing HDDs in systems where performance is not critical. The Silicon Power Ace A55 is based on 3D QLC NAND memory with high recording density, which allowed reducing the drive's cost while maintaining capacity.
The Silicon Motion SM2258XT controller is a simplified version of popular solutions—it is not equipped with a DRAM cache, which helps keep the price down, but may limit speed in scenarios with numerous small files or under high system load. Sequential read and write speeds reach 500 and 450 MB/s, respectively, providing a standard level of performance for SATA drives when booting OS, loading programs, and transferring large data. However, when writing large volumes of information for extended periods, speed drops may occur due to the specifics of QLC memory and lack of buffer. The declared resource is 1.5 million hours of mean time between failures. The device is supplemented with an official three-year warranty, meeting the requirements for consumer SSDs of this class.

Do not take from me and did not live 1.5 years Speed Uptime  Jey West: use Silicon Power SP128GBSS3A55S25 more than year |
A simple ssd, and, as they say, it’s understandable by clothes. The usual plastic transparent container, and the disc itself, that's all. No fasteners, nothing. I personally don't mind, I'm just saying it like it is. Functionally, it is also a normal disk. The peak speed that I measured was a little over 500 MB for reading and 400-410 for writing. The only thing is that files larger than 18 GB in the end clog the buffer, and the speed drops from 400 to 100-80 MB. In principle, it is not critical, and this is extremely rarely transferred to the disk. I use it as the main, under the operating system. I replaced the usual hard one, but the system loads many times faster. It is also normal for programs, they load quickly, which is not surprising at a speed of 400 mb / s and more. If someone is looking for an inexpensive, but full-fledged substitute for the usual hdd, this is it. The price is mega pleasant for such volumes and speed combined. More than fast for the money. The buffer sags after 18 GB in a single file. But I don’t even consider this a minus, because the price eats up all the minuses.  Anton Ch: use Silicon Power SP128GBSS3A55S25 few months |
