Silicon Power A55 1TB 2.5" SATA III 3D NAND SSD, SP001TBSS3A55S25 Solid State Drives (SSD)
Time is money - don't waste it 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 A55 is able to boot your computer or launch applications within seconds. Bad block management for higher reliability Even new disks can contain one or more bad blocks which may cause irreparable damage to your system. But have no fear! To prevent flash memory corruption, the A55 is built with bad block management technology. Bad blocks are continually monitored and replaced to keep your system in good condition and to improve reliability and endurance of the SSD. Durability and performance Equipped with an original controller and 3D NAND flash, the 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 A55 will bring you a smooth, lag-free experience. SLC Cache Technology The A55 applies SLC Cache technology with an advanced caching architecture that combines both SLC and TLC flash blocks. This technology enables all data to be written in the SLC section before being sequentially copied to the TLC block, and as a consequence allows for higher peak writing performance. The A55 also uses "DRAM buffer cache" to improve overall performance and to reduce write amplification on the TLC portion. This leads to enhanced endurance and a longer lifespan of the SSD. Internal auto-copy technology The A55's auto-copy technology allows automatic copy operations from the SLC cache to the TLC blocks inside the NAND without using the controller or DDR. This supports higher efficiency by reducing the controller's and DRAM's workload.

Silicon power I was hesitant to buy when I first heard of the brand but for the past few years I have had not 1 failure. I also like the smaller sizes as they are 128gb 256gb and 512gb instead of all the other brand being 120, 24 or 250 and 480 or 500. So that little bit of additional space is great

i have the 1tb i wanted to use it for games but whenever it starts filling up it slows down to the point it slows down my pc when i reformat the drive my pc goes back to normal speeds i would never reconmend this brand to my worst enemy
Cant fault it,im not a super gamer or heavy pc user, But I bought this ssd for an older laptop (2years now) that was a retired photo/video editing machine to be a dedicated media hdmi to tv laptop.This thing bought it back to life and to be honest Ive used it every single day for the last year since i bought this drive (along with a external hard drive cloner) and it hasnt let us down at all.Ive run photoshop on it, Gta iv, euro truck sim, media programs and the laptop is quicker now then when i bought it.To be honest I bought two more and put them into friends laptops and they seem to be a pretty solid drive. Backed by a 36month warranty as well.Id honestly not done all the super in depth research I would usually do and just bit the bullet and bought this ... MoreCant fault it,im not a super gamer or heavy pc user, But I bought this ssd for an older laptop (2years now) that was a retired photo/video editing machine to be a dedicated media hdmi to tv laptop.This thing bought it back to life and to be honest Ive used it every single day for the last year since i bought this drive (along with a external hard drive cloner) and it hasnt let us down at all.Ive run photoshop on it, Gta iv, euro truck sim, media programs and the laptop is quicker now then when i bought it.To be honest I bought two more and put them into friends laptops and they seem to be a pretty solid drive.

All i can say is that I coudlnt personally justify spending big for the other brand names,Maybe if I was still using the laptop commercially Id buy a big name brand for extra peace of mind, but from memory plenty of samsung and other ssd's had problems too and if you have a backup system in place it shouldnt matter anyway.But its been 12months without a hickup and as I said I cant fault it.For the price its well worth trying!
I needed flesh colored paint and these 2 appeared too pale after drying, for what I needed. I just went too Walmart and found the same paint for 50 cents a bottle.
Excellent product and is fast. If I ever need another SSD I would not hesitate to buy another Silicon Power product.
I never had a problem with this product, great performance low price.
Easy install, cloned the software with a download from Silicone Power website. THINKPAD T420 is now very fast and reliable.
Very good shopping. Works perfectly.
