Silicon Power 128GB SSD 3D NAND A55 SLC Cache Performance Boost SATA III 2.5" 7mm (0.28") Internal Solid State Drive (SU128GBSS3A55S25AH)

i bought this i think almost 2 years ago it has never given me problems i own 2 ssd's from this company and when i end up buying more its going to be this brand too since i have good experience with them i put them threw hard work as i use them to install large mod packs im talking 700 gb mod packs for skyrim and stuff they load super fast too given how big the mod packs are that im playing from them they are super easy to install since they are sata ssds pretty much plug and play which is nice overall really good and the price is super nice for what you get

Using 2tb for 'modernizing' of a PS4 pro. Installation easy, does the job you expect of a SSD in this cost bracket. Can't speak for long term longevity, or comparitive read/wrote speeds on competitive SSDs, but does the job well enough as a budget HD. Recommend a back up be kept for long term contingency as a fail safe for saving any data of importance, just in case of failure after years of usage.

it a good value for a fair bit of storage, but lets be real, no, its not the fastest cutting edge drive .. fantastic for storing games etc.. what i can tell you from past experiences with many drives, particularly sata, is its easy to wind up with flakey low level/boot sector/partitions letting windows set them up, and especially a raid subroutine IF ITS MESSED WITH MORE THAN ONCE .. that seems to be where the problems start, ive had drives jacked up beyond all recognition using the standard tools ... best bet - get yourself a respected partitioning app, delete and re-set up partitions and set your drives up with that, saves alot of headaches ..

The SSD works well I used them for 4K video storage in SABRENT 5-Bay USB-C Docking Station and have no issues they just work. great product

FINAL UPDATE: 6/20/2023=====================Well this last batch (23015096) is failing now too with I/O errors on blk_upddate_requests. I am cutting my losses at this point - not even worth RMAing as the new drives they sent back are garbage too. While I could keep claiming RMAs, I have to pay for shipping each time. It's no longer cost effective to try to get stable drives. $$$ wasted now. Only acceptable solution at this point is a full refund but unfortunately the drives lasted long enough to outlast Amazon's return policy. (To be clear I am not faulting Amazon for any of this - the fault lies fully with Silicon Power and their garbage SSD line).Drives show no SMART error but fail to handle writes during resilvering. Not suitable for storing data, much less "RAID" use as the product claims.UPDATE: 6/7/2023===============I just received my RMA replacements for the 3 drives drive below - this new batch 23015096 has some changes again, shouldn't be a surprise by now...Firmware: H220916aSize: 2.05TB/1.86TiBDRAT/DZAT *is* supportedCase is now made of metal instead of plasticQuality remains to be seen and given the extreme variance within the product line my prior review still stands. A potentially OK replacement does not make up for the inability to provide a good product the first time - data is too valuable to risk to random drives.UPDATE: 5/17/2023================I now have 3 more failed drives - all have serial numbers starting with YTAK from batches 23000184 and 23003845. These 3 latest failures powered down during a reboot and then refused to power back on at all. No system recognized them now.For those keeping score, I now only have 3 of these drive left alive, their serials start with AA (2TB, Firmware V0303B0), BB (2.05TB, Firmware SHFM60.0), and BC (2.05TB, Firmware SHFM60.0). Drives BB and BC are from the same batch. The AA drive is the first drive in this line I purchased end of October 2022. The BB/BC drives are from March and April 2023 respectively. The failed three (YTAK drives) are from December 2022 and February 2023. All drives were purchased exclusively from the Silicon Power merchant here on Amazon.The A55 2TB drive line is a complete disaster - do not trust your data to these drives. Regrettably these latest failed drives are under warranty but not within the Amazon return window so I am stuck with a RMA drives which will result in A55 replacements that can't be trusted...Too bad I have to give at least 1 star for a review - this product doesn't deserve even 1 star...UPDATE: 5/8/2023===============Verified that batch 23011662 with firmware HPS2704M is bad. All drives in this batch fail with the same errors when subjected around 5 hours of continuous writes. Since there is no way to determine which drive belongs to which batch when ordering (or even if any future batch will resolve this) the product is no longer able to function as intended - it corrupts data when writing.They were nice while they lasted but I can't rely on drives that change their internal hardware so frequently and then with relatively high probability of producing faulty devices as a result. I may consider them again at some future point but at this point I can't trust these drives to store my data. Rating is formally reduced to the minimum (1 star) as such a volatile produce design is unacceptable. If you get a good drive it will be fine but drive roulette is not game to be played.UPDATE: 5/7/2023===============Formally reducing review by 1 star (now 3 stars) because of the new 23011662 batch with firmware HPS2704M drives. The drive in my prior review was of this batch and so was it's replacement. Both drives show ATA errors already (this new one as soon as I plugged it in) and neither drive supports SMART self-tests (prior batches/firmware did - as do ALL other SATA drives I've ever used). SP tools do not (yet) recognize these drives so they can't run tests on them nor is there any new firmware to update to. The ATA error appears to be some sort of bug in the firmware that may not necessarily affect drive functionality so in a slightly risky move I am attempting to resilver onto this new replacement - time will tell if it suffers the same fate as the one it replaced. I also have another unopened drive of this same batch. I will be waiting a little before opening and testing it, pending the results I see here.This represents a significant reduction in quality control and makes me question further purchases. For now I am considering this a batch specific issue but if this continues I may need to review my star rating and find a new drive manufacturer.UPDATE: 5/1/2023===============I have purchased 8 of these drives so far for use in my ZFS pool. Overall I am pleased, especially for the price - they are replacing mechanical drives of comparable specs and as expected greatly outperform the spinning array.Quality control seem to be an issue though - of the 8 drives (technically 9 drives) two have now been defective shortly after arrival. As in showing I/O errors within 10hr of operations. This latest entry had a firmware version of HPS2704M and had ATA errors starting around 4hr resilvering mark (heavy write operations). It also refused to run SMART self tests - a bit odd since it does report SMART data... I might just have bad luck but we shall see as I have more drives to replace. 2 of 9 being faulty isn't good odds from my personal experience. The drives that work are working fine - no issues there so it seems that so far either they die quickly or work fine.Other interesting bits of information that might be useful to some - I run raidz2 with 8 drives per vdev. This last drive would have been the final replacement to an all flash vdev. I was getting sustained resilver speeds of around 350MB/s for several hours (i.e. up until failure). Back when the vdev was more spinning than flash I was getting speeds around 200MB/s for resilvering to flash and about 70MB/s resilvering to SMR 5400RPM drives - so overall a decent sustained performance despite being DRAMless.UPDATE: 2/6/2023===============The drive with firmware SN12429 (2.05TB) had write errors, only detectable via dmesg and ZFS error counts (SMART, badblocks, self-test, etc. all said everything was fine). Drive had to be RMAed.RMA process was quick and easy. Replacement drive has been received but is using firmware V1031C0 (2.00TB) which lacks DRAT/DZAT (not a big deal, just leaves me a little confused as to which firmware and feature set is supposed to be current and further proves the hardware variance despite using identical models and external appearance).(No firmware updates are available as per their firmware tool.)UPDATE: 1/6/2023===============Since for my use cases the limitations from my original review are acceptable I purchased another of these drives just a couple months later and I am surprised (in a good way) to report that the latest drive I received has a different firmware (possibly controller and/or NAND chips - not going to disassemble to verify).This new drive has firmware SN12429 and is 2.05 TB (1.86TiB) so slightly larger than the older drive. This new drive also DOES support DRAT/DZAT. Trim appears to function on my LSI 9211-8i (IT mode) under ZFS (2.1.4) with this drive.Other than those difference the drive appears to be otherwise identical to the older one. Hopefully this change remains in future drives, if so this is a decent drive for RAID/ZFS home use.Star rating remains unchanged as there is no way to know which version of the drive you have until you plug it in.Original Review (11/1/2022, Still Valid)=======================Does what it should for the most part. It does slow down once you fill the SLC cache (as expected).Plastic casing (common for lower end SSDs) gives it a cheap and non-durable feel. This shouldn't matter too much unless you are doing a lot of hot swapping of the drive.GParted reports 1.82TiB usable space, the same as the 2TB HDD it replaced (so storage is a true 2TB not 1.92TB like some other "2TB" models - this matters when replacing drives in arrays).Does not support DRAT/DZAT (Deterministic Read ZEROs After TRIM) - meaning no TRIM when connected to an LSI/Broadcom HBA. So while SP claims TRIM/RAID support it won't fully operate in all cases. Unfortunately the LSI/Broadcom HBAs are quite common and popular.Firmware V0303B0

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.
