    • Seems to be very good value, more trouble to find what would work than to install.
Capacity: 1TB Style: 2280 M.2 SATA
Silicon Power M.2 2280 SATA 1TB SSD. Installed in Dell Inspiron 3470 Small Form Factor Desktop built in 2019. Biggest issue was determining what SSD card to get. NVMe will not work in this machine, and most offerings for a 1TB card are NVMe, so I settled on the SP brand. I needed to match the existing 1TB HDD to be able to clone without partitioning, then use the SSD as a Boot Drive and the HDD as a backup drive. Within 2 hours after UPS delivered it, I was up and running without any problems. I used Macrium Reflect 7 (Home Edition that I purchased during the Black Friday sale) to clone the SSD from the HDD, about 30 minutes. Watched a YouTube video for instructions to change the designation from E to C drive and rebooted and everything worked as hoped and wow, what a difference. Downloaded DiskMark 64 to test the read/write speed and got the following results. HDD Read (MB/s) 184.76 Write (MB/s) 171.61 (Top line results) SSD Read (MB/s) 552.85 Write (MB/s) 439.23 (Top line results) This is my 3rd upgrade from HDD to SSD as boot and retaining HDD as backup. One Windows HDD to 2.5 inch SSD, one Apple MacBook Pro from HDD to SSD (replaced HDD) and this one. All are well worth the effort and expense. All my parts are from Amazon, no issues just ordered the mounts with the 2.5 inch and didn't need anything for the M.2 slot. Since I wanted to retain the old HDD, I didn't have the option to just add a 2.5 inch SSD because the drive bay was not big enough to mount a SSD and HDD. I did not rate the Longevity because only time will tell. Since I kept the old HDD as a backup and will schedule monthly backups, failure will not be fatal. ... show more

    • Trusted the other reviews but this brand is instant garbage - Failed after 3 months of light-duty
Capacity: 1TB Style: 2280 M.2 SATA
I just needed an SSD for an enclosure to operate as a backup drive for my Time Machine (OS X). This drive, nearly like clockwork, will mount and begin to accept the backup, but within 10 seconds will fail and disconnect from the computer. I have tried multiple housings and internal drive connections, and every time it behaves the same. Poor quality. Spend the few extra bucks and get a brand-name drive that is more reliable. This is just instant garbage. ... show more
