Will this work on Macbook Pro 2012 non-retina A1278?

Absolutely it will! I have the 2TB QVO 870 in my Macbook Pro 2012. Works flawlessly. If you use the Disk Utility to clone from an upgrade (from Recovery mode) don't forget to go to Startup Disk in System Preferences to select the new disk afterwards.

Does it come with a sata cabel?

It does not, I had to order extra data cables along with it.

Does it have power loss protection?

Ignore the answer about journaling, it's only meta-data journaling, not full-data journaling. Yes, you can still have data not committed on a power loss. Meta-data journaling, which NTFS, Ext[34]/XFS and other file systems do, only mitigates the change the file system is inconsistent on a journal replay after power loss. Meta-data, such as date, allocations (FAT in NTFS, iNode in Ext/XFS), ownership and permissions are what's stored in the FAT and directory attributes in the case of NTFS, and the inodes and areas like the superblock in the case of Ext/XFS. Inconsistency is what causes future data loss, so meta-journaling and any replay after a power-on is so the file system remains consistent aka 'well ordered.' But data blocks may still be lost as a result of a non-commit, which is not made to the journal, only meta-data goes into the journal. Consumer NAND devices use DRAM for buffering and, at best, have capacitors and maybe 1-bit SLC or 2-bit MLC for buffering some writes, before it is written to 3-bit TLC or, in this case, 4-bit QLC. But they are not really designed for data loss prevention. The NT kernel in Windows also isn't designed for NVRAM on the system board, and 'raw' management of the NAND cells themselves. That's why consumer NAND devices continue to ship DRAM. At one time Microsoft had a more embedded/mobile OS called CE that did do some of these things, but it is long gone now. The Linux kernel is the opposite, and can actually manage raw NAND cells and support NVRAM directly on the system board, so it could have a means to ensure all data is written post-recovery. There are also new 'zoned' devices from storage vendors that are really high density, low cost, including specific file systems, like Western Digital's ZDS. But these are only supported by designs like the Linux kernel, and not on Windows. And because Windows dominates PC sales, the consumer devices available at economies-of-scale (lower cost), have to be Windows compatible, even if the Linux-only hardware is cheaper to make. So, just like GPUs, specialized storage devices that can take advantage of Linux features are all data center-specific, where Linux is the massive OS of choice, so the vendors make the most money there. It's not worth them to sell to consumers.

Mine seems slower to boot and normal operations. Windows 10 latest update. Also using magician, why?

Download the latest version of Samsung magician and add a 5 or 10% OP Operational Cache and then turn on Rapid Mode an it'll perform faster by a lot. The OP cache allows it to cache its data through its controller to use and also protects the drive from using up all its space. If you example have a 1TB an you use the full 938GB it'll be a lot slower, you'll need an want 5-10% For a cache.

Reasonable price. Faster than SAT HDD

I'm happy with the product. The price is reasonable and the performance as EXPECTED.SAT SSD is not fast as SSD but this is expected. But it is also better than SAT HDD. it is recommended if you have SAT HDD laptop.

Fast SSD

I use it to upgrade my son laptop, at the beginning it did not read any thing, then I took it to laptop shop to confirm it is not working. Then I read the Q & A for my case found that when I contacted the ssd go to windows storage management on the control panel it successfully discoverd it then format it.

Great value but beware if using as recording media.

Fantastic value but wish I'd spent a little more for the EVO as it can't handle highest settings on my camera. Great for a computer or 30fps prores.

Huge improvement upgrade

I bought this to upgrade an aging laptop's spinning hybrid HDD. The transformation in startup and performance is huge and makes the second generation i7 laptop feel just as fast as my newer system! The software suite is probably the best, just ahead of Seagate providing all kinds of detailed information on the drive. Simple installation and highly recommended.

I was contemplating building a 5-bay NAS using SSDs for quite a long time but prices were prohibitive. Finally I found these 8TB SSD at an offer price I was willing to pay, so here they are delivered as promised by Amazon. I tested and checked every drive and they are the REAL thing and NOT knock-off clones. Luckily I bought them when I did because the price has gone up significantly. Vigilance does pay dividends.

も，当方ではついにSSDになりました．夏場，自室ではエアコンを控えめにしていることもあり，デスクトップPCのケースを開け扇風機で強風を当てても， HDD温度が40度を超えてしまいます．室温まではなかなか下がりません． SSDに交換することで，大容量HDDの故障の不安が，今夏以降は多少は払しょくされるだろうと期待しています．

Upgraded from the 250gig Samsung. Transferred operating system and many programs/apps using Samsung magician software. No problems. Slightly dearer than othet similar products but worth it.

Adquiri 3 no Day Prime (promoção excelente) e nenhum apresentou defeito, por enquanto. O número de série dele vem escrito também na caixa. Vem com um manual bem completo. Geralmente, os SSDs não apresentam defeito.
