Silicon Power 4TB SSD 3D NAND A55 SLC Cache Performance Boost SATA III 2.5" 7mm (0.28") SSD Internal Solid State Drive (SP004TBSS3A55S25AD)

I installed this drive into a Sata2 based computer to extend the life of a 10 old desktop computer that is still very functional as a non-gaming work and multimedia computer.My operating system boot drive and additional internal storage drives began to fail so I purchased this SSD to replace the operating system drive. Even though this drive in my situation is running at half speed due to Sata2 motherboard the speed of booting into windows desktop from completely off went from between a minute 40 to 2 minutes just to get to the desktop and then another 7 to 10 minutes for the computer to become usable waiting on all the software to load and startup tasks to complete.Replacing the failing spinning platter hard drive with this SSD it takes around 30 seconds to a usable computer in the desktop, all the background tasks loaded and completed and all the software loaded and running.Writes and Reads are faster than a spinning platter hard drive.All software loads and in general operates faster and in some cases dramatically faster.If you have a SATA 2 based computer and it is working but slow, replace the operating system drive with this SSD and you will get 3 to 5 times speed increase. Even if you have been told that your computer will not support SSD's, you just replace your existing hard drive with this and it will just work. Look at installing the most recent BIOS for your motherboard to give some additional features, possibly, but the drive itself should just work either way. Exceptions to every rule but if Windows 7 or above is running currently on your computer, this SSD WILL WORK.I have the 2 TB drive. Windows 7 and Windows 10 in dual boot.When you format the drive and need to choose between MBR or GPT for the file system and you are running Windows 7 then choose MBR.In BIOS set UEFI AND Legacy Boot OR if you just have Legacy option by itself then choose Legacy or your SSD will not be recognized and will not boot windows.If you have Windows 10 ONLY then choose GPT file format and then UEFI boot in your bios. Windows 10 will also work with MBR and you need to set that if you have less than 2TB of space on your SSD. It depends on the size of the SSD AND the operating system(s) you are running.Samsung Magician Software is GARBAGE and does not work either at all or will randomly stop working and you have to uninstall and reinstall the software. I have tried all versions from 6.3 to 7.1.0 and experienced the same result on my system.You only need it to test to make sure the drive is good and does not have bad sectors and to do a secure erase if you choose to do that.If you have a DUAL BOOT system like I do and use their data migration software to transfer your operating systems to the SSD it will fail or seem to work but the second partition with the additional operating system will be corrupted in some fashion. You MUST test and actually use software and do normal use things in both operating systems before you call it good and working.I had to reformat and reinstall using TWO third party paid software to complete the transfer and have both operating systems working. Even then I had to reinstall several applications that I should not have had to. AND reactivate Windows 7 after a BIOS setting change during testing.Due to the failures of Samsungs Data Migration Software for my unique use case it cost me over 2.3TB of writes to the SSD in less than 60 hours of owning the drive. This comes to less than half a percent of life of the drive for life time writes, but still.Every test I used came back NORMAL. The SMART results for all the SMART log fields that show errors all kept coming back 0 on the raw data column. The speed of the drive over time has actually gotten faster according to CrystalDiskInfo and Mark8. Every test keeps showing Normal, no errors.One of the software I had to purchase to migrate my dual boot disk to the SSD has a backup utility and I have been doing daily and just setup hourly backups but so far there is NO issues at all with the drive in using or test results.I transferred a 1TB disk that was in the process of failing to a 2TB SSD and due to Samsungs crap software I had to do this multiple times, multiple reformatting and alignments which is why the process ate up over 2TB or writes in 60 hours of trying to get a stable dual boot system.Due to custom configuration of both Windows 7 and Windows 10 AND thousands of dollars of PAID software with customizations I did not have the luxury or fresh installs. Also Windows 7 is no longer supported by Microsoft so there are no downloads of that ISO any more. I have paid for BOTH operating systems which are the PRO versions and did not get either one FREE.Eventually I was successful in migrating and stabilizing both operating systems and everything that should work, works.EXCEPT for Samsung Magician which is total CRAP software and has seemingly been very buggy from day one and has never been fixed. It is FREE software but is supposed to be the end all be all for Samsung SSD management. It is not. It is SO buggy they had to role back 7.10 to 7.01 and even that version has issues.Samsung Magician keeps telling me in red letters under the Help Center section that my SSD has Failed LBA. Under the actual Test Logs it shows NO ERRORS and Successful Completion of ALL tests.I called Samsung Support and it was confirmed that the software has a bug that produces this false flag message. As long as the Test Logs show no errors and SMART shows no errors then this is a bug in Magician.After I was satisfied that the tests were showing the SSD was 100% I uninstalled the software.After doing this I opened up a Disk Sector Reader and looked at the Over Provisioning space that Magician setup on the drive and discovered it was NEVER written to. All the sectors were 0's... No data written ever...I just did a speed test and it is showing a few percentage faster than the last test so I am happy with the SSD. Some say this drive fails or that the older drives manufactured before mid 2021 are bad batches.The drive I have was manufactured in December 2021 and was brand new when I received it.SMART is showing '0' for all the Raw Data Columns regarding Failure, CRC Errors, Recovered Sectors and swapping sectors with good - forget the name... it has increased to 3 for Wear Leveling which is the stat that tells you how many times the entire drive has been completely erased. 3 times but this was due to trying to get Samsung Migration to work with my Dual Boot setup and then having to use 3rd party software to successfully migrate my operating systems. 1TB's written and rewritten many times to the 2TB SSD.Through this I discovered that this drive can take a lot of abuse and the end result, the drive has gotten faster. The only thing I am sad about is that the computer this drive is running on is only Sata2 I would like to see what it would be like at full speed.Don't use Samsung's software other than to test the drive is working properly, do a couple weeks of tests on the drive, once or twice a day for a few weeks. If all is 100% and no changes in the ERROR counts in SMART.. uninstall Samsung's software and in the mean time setup daily backups using some software other than windows backup and go until it dies.

My laptop took several minutes to load and open any applications. It was constantly saying ‘said application’ was not responding. So frustrating! What should take 5 minutes of my time was taking 20 minutes if not longer. Once this was installed in my laptop, the speed of opening any application has incredibly increased. Very pleased!

Great deal, works great, exactly as described with the read/write speed! 5 year warranty upon registration! I highly recommend seller & product! Thank you Amazon & Silicon Power!
