Kioxia's Exceria Pro G2 writes its whole five-year quota in about a day at rated speed

Take the warranty first. Up to 600TB written per terabyte gives the 2TB model a 1,200TB rated write budget across its five years ^[5][1]. Spread evenly, that is 240TB a year, or about 658GB a day for the whole term ^[2]. At 13,700 MB/s, the top rated sequential write figure, 1,200TB of writes goes by in roughly 24 hours of continuous writing ^[3][3].

Both rated figures belong to the 4TB capacity, and Tom's Hardware says most of that performance is achievable at 2TB, which it calls the likely sweet spot ^[3]. For 14,900 MB/s to show up in your own logs you need a PCIe 5.0 x4 link, largely sequential access, and enough queue depth to keep the controller busy. The review's pros list credits the drive as cool-running and reasonably efficient, so throttling is less likely to be the thing that caps you ^[17].

The OEM-firmware framing is the reviewer's reading, offered as an argument. Tom's Hardware wrote that the drive is "like a Kingston Fury Renegade G5 made for OEMs, providing most of the performance you expect from this class of drive with reliability-minded firmware built in" ^[9], and that "we make the argument that this is a deliberate trade-off for a drive with roots in an area where reliability is a bigger priority" ^[10]. The review names no firmware setting or measured behaviour that separates this part from the retail one. Sustained write performance is listed among what the drive delivers ^[11].

On the EU pre-tax estimates, the cost per terabyte is $190 at 1TB, $170 at 2TB and about $163 at 4TB ^[7][4]. The 4TB gets there with 16-die NAND packages instead of 8-die, and stands 2.63mm tall against 2.38mm for the smaller two ^[12]. Tom's Hardware says that height should not be an issue in most cases but is worth noting for devices with specific limitations ^[12]. Kioxia makes the flash it is using, and the review gives that, plus reduced competition after Crucial left the market, as one reason the price stays down ^[8].

If your build requires a self-encrypting drive, the specification stalls here. The drive reports support for the commands TCG relies on, Kioxia makes no explicit claim of hardware encryption, and Tom's Hardware expects TCG Pyrite 2.01 and software encryption only ^[14]. The PSID on the rear label allows a security reset to the factory state on an unlocked drive ^[15]. All of the pricing above is estimated from pre-tax EU listings, because Kioxia does not officially distribute the drive at US retail and the Amazon.com listings may be imports ^[6][7]. An import also means settling in advance who handles a warranty claim in year four.
