Ace A 55 M.2 2280 128GB SATA III 3D NAND
17 January 2019ADAM S.

This could be an issue with my ASUS ROG STRIX B450-F GAMING MB or this SSD. I have noticed that when it slows down, my USB3 transfer speeds drop too; so it could be a BUS issue. (50GB File Copy from SATA1/2 RAID to M.2 SSD with a second file copy (450GB from SATA4 (single) to USB3 4TB Drive) - the USB3 file copy is faster after the first 10 minute. (I suspect that it's a BUS issue.)) This is on a clean Install of Windows 10 Pro to the SSD.

I would defiantly recommend this product and company and will be buying more to install in client machines.

Best value 512GB SSD for the M.2 form factor

Pros -Simple packaging -Cheapest 512GB M.2 SSD as of the current date -Much faster than my traditional hard drive (transferring my ~400GB steam folder took a few hours rather than a few days Cons -Not the fastest? (Only SATA and not NVME, but at this price point that's to be expected)

It worked great while it worked. I had hoped it would last quite a bit longer than a year. Would not buy again.

I think this is just about as fast as a sata drive can get. Paid $30 shipped. More than happy with my purchase. Sequential Read : 560.984 MB/s Sequential Write : 525.499 MB/s

Fast SATA SSD M.2

Used this SSD in a RPI Argon 1 m.2 case. Perfect fit and worked flawlessly. Fast delivery was great too.

First time installing a M.2 drive
11 March 2022

There's a sticker on it that says "DO NOT REMOVE" but it really looks like it should be removed. I googled it and there were a bunch of articles saysing "DO NOT REMOVE" the sticker. So I looked it up on youtube (known to be the center of everything true on the internet) and found yet more videos exposing "DO NOT REMOVE". I'm not really sure if I should leave it on though.

Great little M.2 256GB SATA III SSD
21 December 2018

Just sharing my solution to emulate RAID1 with a motherboard that only has 1 NVMe and 1 SATA3 M.2 (i.e. 2X M.2 connectors): IF my MB had two NVMe slots, I would have purchased two NVMe SSDs to get the RAID1 security I have used since Day 1 (like a million years ago). I am sure I could still form a RAID 1 using 1 NVMe and 1 SATA3 SSDs, however, I am sure the speed would then be just 6Gb/s (SATA3). The next best thing is to provide a "close-enough" "recovery" solution - just in case the Samsung unit ever fails! I clone the Samsung unit (with only 1 partition) to this Silicon Power unit every day. If the Samsung failed, I can use the SP unit as boot drive, not even need to open up the PC case (so I can keep working). Folks, if you have lots of money to burn, you don't ... MoreJust sharing my solution to emulate RAID1 with a motherboard that only has 1 NVMe and 1 SATA3 M.2 (i.e. 2X M.2 connectors): IF my MB had two NVMe slots, I would have purchased two NVMe SSDs to get the RAID1 security I have used since Day 1 (like a million years ago).
