SP 1TB SSD 3D NAND A55 SLC Cache Performance Boost SATA III 2.5 7mm (0.28) Internal Solid State Drive (SP001TBSS3A55S25)

Used this to upgrade my old iMac and so far so good. A good performance boost from the old HDD.

Excelent SSD 2T and a convenient price. Thank you

I have three of these disks (1 TB) installed in a ZFS pool (no mirroring, no raidz). I needed cheap SSDs for my workloads, which are heavily write intensive, but require sporadic, small sized, random reads, a few times every second. Well, NAND flash can be great for that. Or at-least thats what youd expect. Sidenote: if you know anything about 7200rpm spinning drives, you know they can sustain a reasonable ~150-200MB/s sequential write, but throughput will suffer quite a bit if they need to simultaneously seek to fetch non-contiguous data. And then theres the issue of limited IOPS. I wasnt expecting miracles from these SSDs, but I was certainly expecting each to sustain atleast ~200 MB/s sequential writes. Well lo and behold, once you blow through the onboard SLC cache after a measly 30 seconds of writes at ~500MB/s, the drives start choking. Nothing more than ~65MB/s after that. I know these are TLC drives with SLC cache, but woof, those numbers arent great. So, if your workload isnt write heavy, by all means get this thing. But Id think youd want a little more performance out of something only fractionally cheaper than better performing alternatives. Also, no benchmarks posted on here use a large enough test file size to actually blow through the SLC cache, so the only thing you see results for is your SATA connection and/or packet congestion in the PCIe lane. On the positive side, sustained read performance was as expected, saturated the SATA III link without any issues.

Using it for months now. No problem at all. Great item.

I directly copied over my O.S. (Operating system) from a mechanical Hard drive (HD) to the SSD using Macrium Reflect. The boot time of Windows 10 / 64-bit is never speedy {even with the SSD - about 20-25 seconds from BIOS logo to windows login}. The noticeable speed difference will come when you launch bulky applications like: Photoshop, games, photos, etc. Boot time will vary depending on different factors. The Silicon SDD speeds are the same as the Samsun 860 EVO 1TB (Up to 550/520MB/s seq read/write speeds). My tests are showing A55-1TB Silicone SSD with 550/440MB/s (screenshot posted with this review). My speeds are not tested with an Empty drive the A55/SSD was tested with a fully functioning OS on it (20% of the drive filled during testing). This is a fast drive at a reasonable price. IF, anything should occur with the hard drive over a period of time I will return to update this review (if possible). I am using three different variants of the Silicone SSD: 1TB, 480GB, and 256GB. (desktop, laptop, desktop) All three SSD drives are meeting or exceeding their competitions speeds. A note to all Windows users, please change your advance settings / hard disk timeout in your control panel unless you dont care about very noticeable lag spikes when you open or launch applications/documents. This is under control panel, top right search box type power, left window Edit power plan. Change advanced power settings, Expand Hard disk by clicking on the + symbol to the left of it. Click on the + symbol to the left of turn off hard disk after, click on Setting change to 0 minutes. (do this for M.2/NVME/SSD) otherwise you will wonder why your highspeed drive is acting slow. UPDATE: I have now purchased about 5 Silicon SSD (2.5) drives. ALL 5 are still working very well 5 months in. I have done speed tests on a few of them every month (I have multiple sizes: 256, 512, 480, 1TB) The speeds are stable. Meaning you will get a slight variation (either faster or slow) in the speed test numbers but nothing dramatic. If you are concerned about data loss, get a second hard drive (mechanical if you wish). Go get Macrium Reflect, home edition, and you can make a direct copy of your OS boot drive into an image file. Macrium is a UK based software company that has powerful free (home edition) software. YouTube has wonderful videos on how to do this, very simple. Remember to buy a USB stick (2GB more than enough) to make a media boot for recovery purposes.

The SSD performs really well for the price (400ish write/read speeds), but I would recommend getting a better SSD if you plan on copying tons of data on it repeatedly (+500GB) in one sweep, cause it does throttle down to 20MB-30MB.

So I just purchased two more of these drives which are used in laptops around the house. The one that I purchased 4 years ago died at exactly 3.5 years. If you use these for anything more than light storage, the drives themselves will just stop responding to anything after the warranty expires. No complaints on the actual drive during use, and they seem very stable until they crash hard.

I got this basically non-stop since November 2022 and its been great. Ive had no trouble moving it around to various computers, and anything I have on it loads up nice and fast. I know technically this isnt as fast as some of the other drives out there but for last gen/pretty simple gaming and other applications I havent really noticed a difference. Highly recommended for storage for setting up a MiSTer or other similar FPGA or emulation box or other small project.

Reading is fast, but writing is different from MX500. I wanted to get this as a temp storage and mainly for reading. If you need a cheap SSD, this may serve you. If you need constant reading and writing, get a Crucial or WD.

Never had a drive without serial numbers before. All 000000000s here. Seems to be working, good bang for the buck. Also the cheap comes out expensive. Was not recognized a few times needed to coax it to be mounted in the system. Installed Dell rack server as a VM. Only had to a day and not impressed, hope it changes my mind over time.
