Crucial M550 SSD Review (1TB) – Increased Speed, Capacity and Value

It’s been some time since Crucial introduced the M500 Series SSD and, as it was when first released, the M500 remains to be a top value premium SSD offering. At $439 for a 960GB M500, this translates to .43/GB which is still lower than some premium SSDs of half that capacity.  Not so much a difficulty with respect their  target market, performance of the M500 family was a bit lower than the competition, although Crucial seemed hit a bulls eye when considering capacity and value.

Today’s introduction of the Crucial M550 SSD family is intended to cross that speed hurdle, offering the consumer the perfect combination of performance, capacity and value.  Crucial has accomplished this, not only through introduction of a new Marvell SATA 3 controller, but also by effectively using both 128Gb NAND, as well as 64Gb NAND, to tackle the performance numbers we saw in the M500. Will the Crucial M550 have what it takes to conquer the SSD triangle of speed, capacity and value?

PRICING AND AVAILABILITY

The Crucial M550 SSD will be available at the time of this reports publishing (Check here!) and Crucial has identified this SSD as being a 15-20% price increase on the M500 SSD.  The goal of the M550 is to attract power users and gamers, while still holding a very competitive price point with that high 1TB capacity point.  When calculating current pricing, we should see the 1TB capacity of the M550 at the low $500 mark.  Check Amazon pricing!

M550 PACKAGING AND COMPONENTS

The Crucial M550 is a 7mm notebook SSD which also includes a 7mm to 9.5mm spacer for older systems.  Exterior packaging consists of a simple cardboard exterior of minimal detail.

There is a thermal pad that is on the exterior casing and sits upon the controller to dissipate heat, this also resulting in the branding being a bit difficult to photograph.

By using the Micron FBGA Decoder, we can identify this memory as having the product number MT29F512G08CKCABH7.  It is 20nm mlc NAND flash memory with each module being 64GB in capacity.  Although the total RAW capacity of this SSD is 1024GB, the user will only have 954GB at his disposal for storage .

Like the M500 family, the M550 contains power capacitors that ensure your data is safely stored should a power failure occur.  Even with the M500 having been released just under a year ago, this remains to be a feature not seen in the consumer SSD arena.

Timing was good for the 550…the 500 was quickly slipping to the under-performing ranks of the asynch value drives. Best thing from this new launch was the decision to bring back 64Gb die and thus the very desirable jump in performance with the 128GB drives. Combine that with power protection and good crypto and you have an unmatched offering that is perfect for those looking for a dependable/affordable ssd for their lappy. Doubtful anyone without their own nand fab will be able to follow suit re: the 128GB offering. Well played indeed.

Well to be fair, async drives tend to perform MUCH worse than m500. Remember, its not all about sequential speeds. m500 is performing just fine, especially given the price.
And m550 is not meant to replace m500 in any way, it’s just a better performing verison of m550. m500 is here to stay (atleast according to crucial)

The m550 is a better performing version of m550? This is a Mark II or something?

Hello mr necro-poster, he clearly meant to say:
“And m550 is not meant to replace m500 in any way, it’s just a better performing verison of m500.”

The differences are very marginal though, see the Anandtech review…
Unless prices have come down a lot more since the review, the M500’s a better buy.

couldn’t agree more, I upgraded my MBP 2012 which is loaded with gigs of music (Hi Re Albums Arts) many applications. I’m so happy right now, as long as it preform and launch my application so fast.

how does the Native
Write Acceleration of the m550 work? is it a cache of some sort similar
to how samsungs 840 evo turbowrite feature works? would i lose all unwritten data if their is a system error? can it be turned off?

I believe its just a marketing thing for highspeed writes caused by using smaller dies (and thus more of them for a given capacity).
Crucial unlike other competitors isn’t using any kind of tricks to achieve writes speeds such as turbowrite and performance mode.

what is the m.t.t.f./m.t.b.f. and the t.b.w. for it?

you read my post incorrectly, NOT what is m.t.t.f./m.t.b.f., but what are the m.t.t.f/m.t.b.f. and t.b.w. for the M550?

I was refering to mtbf rather than TBW and thanks for that.

Why would MTBF matter to you anyway ?

its not like drive with higher mtbf is gonna last “longer” anyway.

Oh man, this is awesome! I was about to purchase a SanDisk X110 or X210 for my Drobo, but I’m liking this! Let’s see some M550’s as loss leaders at Slickdeals, huh? haha…thanks for another great review! You are THE SSD man! ~
