A time period, most often three or five years is also enforced. The TBW ratings represent the amount of writes vendors determine they can guarantee and still make a profit at the price they charge. They’re generally a deliberate underestimate of monumental proportions. The thing about TBW ratings is that they’re not particularly accurate. You might not realize that a ton of temporary files are written then erased on the SSD, including the memeory swap that’s the issue with the new M1s
Typically the rating runs around 600TBW for every 1TB of capacity for end-user drives.

Samsung’s 980 Pro is a typical end-user SSD, “rated” for 600TBW for every 1TB of capacity.Īs for vendor ratings, by far the most common stat used for solid state storage is TBW, or the number of TeraBytes that may be written over the life of the drive. The fine art of controller design has come a long way, and I haven’t heard of a failure in years. As it turned out, it was hardly ever the NAND failing, but the controller locking up. That’s due partially to the early days of SSDs, when the lifespan of NAND flash storage used on an SSD was severely underestimated, and drives often quit after a relatively small amount of use. SSD longevityĪ common misconception about SSDs is that they don’t last very long.

The reports became a cause for alarm for M1 Mac owners, but is it really a problem? While it’s true that SSDs have a limited lifespan, how long that SSD lasts comes down to how you use your Mac.Įditor’s note: updated on to reflect further information about Rosetta 2 translation and specific programs that may cause excessive wear. One in particular showed 15TB written in two months. That’s quite a bit, and almost certainly due to swapping main memory to the SSD. We have found that customs offices and international post offices are constantly losing packages and destroying parcels: and we simply do not wish to accept liability or the increased costs of these transactions.Recent reports have shown that some users of M1 Macs are experiencing what they feel is unreasonable, excessive usage of the SSD. These terms may seem harsh – and if you find them to be, I reiterate: if you live outside the United States: I would highly suggest you find a local repair shop! If you are outside the United States, we are NOT a good option, are not trying to convince you that we are, and suggest you look elsewhere before sending us a device under those terms. If a device is lost in transit either way, we are not liable or accountable, on any shipments outside the United States.return shipping, even on warranty issues, is the responsibility of the customer. We do not cover shipping, even on warranty issues.We do not cover shipping, either way, whether or not we repair it.That being said, if you want to send something to us, outside the United States: International shipping restrictions, terms, and conditionsįirstly, if you live outside the United States: I would highly suggest you find a local repair shop! Dealing with customs and international shipping adds cost and time, and we cannot guarantee delivery times on international shipments. We are not able to service any device that contains urine, excrement, or insects. We do not service devices that are contaminated with human or animal waste. Please do not mail us iMacs: bring them in person or find someplace local. To be clear, we take no responsibility for shipping damage on iMacs since our site says that we will not work on them if mailed to us. Unfortunately, they send us iMacs anyway, and they wind up damaged in shipping. We have told several people over the phone that they should not send us iMacs because of potential for shipping damage.

We only work on devices when the full machine is sent – we do not work on board only repairs where the logic board is sent by itself. However, we do not service 2011 Macbook Pros with AMD graphics with board 820-2915 or 820-2914. We service 2010 15″ machines with 330GT graphics for kernel panics, and 2012 retina machines with 650 nvidia graphics for kernel panicing/blank screen. We do not service 2011 Macbook Pros for GPU issues. If you are a computer repair store, worked on it yourself prior to sending it here, destroyed it, and do not contact us in advance, we are not fixing it and will make fun of you live on camera. If sending in a board that has had prior work, please contact us first to see if an exception can be made in your case: same for hard drives. We do not work on boards or hard drives that have been already worked on.
We do not service logic boards and hard drives with prior work.
